The mildest skin cleansing products can, at best, produce cleansing without negatively affecting the skin condition. To achieve an improvement in skin condition, the consumer is forced to use a second, separate product often called a "moisturizer".
The use of two separate products to achieve the desired skin state is inconvenient and often unpleasant due to the greasy skin feel resultant from many moisturizers. As a result, many persons suffer from the effects of poor skin condition rather than use two separate products.
There is a clear need for a system which is capable of delivering both mild skin cleansing and a skin conditioning benefit; since most people don't use a moisturizer daily. Some skin cleansing products contain humectant substances which, although effective in topical application, are ineffective in cleansing products. These humectants are ineffective because they are very water soluble and suffer from poor skin substantivity. Hydrophobic emollient m~trrial~ are generally more substantive to the skin, but are more difficult to incorporate into an aqueous skin cleansing matrix and/or are absorbed into traditional cleansing instruments. There are also at least two other sources of difficulty typically encountered with such liquid cleansers: poor lather effects and physically unstable product.
The present invention allows for the use of a selected sponge with a lathering cleansing and moisturizing liquid cleanser Col~t~ an effective amount of hydrophilic, oily or hydrophobic moisturizer and mixtures thereof.
The present invention allows for the use of higher levels of humectants in a "cleansing and moisturizing" lathering liquid to provide a cleansing system which is better lathering, milder and more effective than the prior art kits.

SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a personal bath or shower body cleansing system comprising:
(a) a lightweight polymeric meshed personal cleansing hand held sponge, the polymeric mesh sponge being in a form suitable for use as a hand held cleansing implement; and (b) a cleaning and moisturizing liquid comprising, (1) a moist-lrizing phase comprising an effective amount of a skin conditioning ingredient; and CA 0216~0~0 1998-04-20 (2) an aqueous phase comprising an effective amount of a surfactant selected from the group consisting of soap, synthetic surfactants and mixtures thereof.
In accordance with another aspect of the present invention, there is provided a method of cleansing and moisturizing the skin comprising applying a cleansing and moisturizing liquid to a personal cleansing implement, the implement comprising a polymeric netted mesh, and applying the liquid to the skin with the personal cleansing implement in a manner to create a lather, wherein the cleansing and moisturizingliquid has at least two phases comprising:
(1) a moisturizing phase comprising an effective amount of a skin conditioning ingredient; and (2) an aqueous phase comprising an effective amount of a surfactant selected from the group consisting of soap, synthetic surfactants and mixtures thereof;
such that an effective amount of the skin conditioning ingredient conditions the body skin.

CA 0216~0~0 1998-04-20 - 3a -DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The Personal Cleansing System This invention is a kit or system that includes a hand held bath sponge and a cleansing and moisturizing liquid cleansing composition. The system is sued for cleansing the skin with a mild liquid cleanser with good lather while "conditioning" or "moisturizing" the skin as it cleans in the bath or shower. The need to use a separate lotion or oil on the skin after the bath or shower is greatly reduced. Thus, the liquid is called a "cleansing and moisturizing" cleanser and the package with the mesh sponge is called herein a mild lathering cleansing and moistllri~ing personal cleansing kit.
The mesh sponge and the cleansing and moisturizing cleanser are packaged together in a kit.

CA 0216~0~0 1998-04-20 The liquid cleanser is usually contained in a separate container in an amount large enough for several uses with the mesh sponge.
The personal bath or shower body cleansing system comprising:
(A) a light weight polymeric meshed personal cleansing hand held sponge; said polymeric mesh sponge being in a form suitable for use as a hand held cleansing implement, said hand held sponge having a diameter of from about two (2) inches to about eight (8) inches (5.08 cm. to about 20.32 cm.); preferably the polymeric meshed personal cleansing hand held polymeric mesh sponge is made of polyethylene diamond mesh and has a diameter of from 3 to 5 inches (7.62 cm. to about 12.7 cm.) and (B) a liquid cleanser having: (1) an effective amount of a skin conditioning and moistllri~ing ingredient; and (2) an effective amount of a surfactant selected from soap and synthetic surfactants and mixtures thereof; preferably the skin conditioning and moisturizing ingredient is selected from the group consisting of oils, cationic and nonionic polymers, and ~ lules thereof; and said surfactant selected from mild soaps and mild synthetic surfactants and mixtures thereof; and preferably said cleansing and moisturizing liquid cleanser (1) also contains from about 0.5% to about 10% by weight of said liquid cleanser of a skin conditioner selected from the group consisting of esters of fatty acids; glycerin mono-, di-, and tri-esters; epidermal and sebaceous hydrocarbons such as cholesterol, cholesterol esters, squalene, squalane; lanolin and derivatives;
mineral oil, silicone oil, silicone gum, and vegetable oil, and mixtures thereof; and preferably said liquid cleanser contains from about 0.7% to about 4% by weight of an emulsified petrolatum which has a melting point of from about 50~C to about 60~C.
The Polymeric Mesh Sponge and the Cleansing and Moisturing Liquid Cleanser The polymeric mesh sponge and the otherwise low lathering cleansing and moisturizing liquid cleanser together provide a superior cleansing skin care system vs. the prior art. The cleansing and moisturizing (2-in-1) liquid cleanser provides - "moisturization" via deposition of a oily material in the 2-in-1 liquid cleanser on the skin surface which material is known to improve skin condition and at a level that surpasses the threshold for a noticeable benefit. It has now been discovered that this can be accomplished by the present invention.

CA 0216~0~0 1998-04-20 It has been found that this cleaning system, comprising a polymeric diamond-mesh bath sponge used in combination with a cleansing and moisturizing liquid cleanser, provides many unexpected advantages over the prior known systems. The present system for example possesses the ability to provide both excellent lathering 5 cleaning action and skin conditioning action in one step, so it is not necessary to utilize two separate products for both such actions. In addition, the polymeric mesh sponge possesses a hydrophobic mesh netting surface which allows the cleaning solutions used in the cleansing and gentle scrubbing action to form a rich lather while at the same time permitting the moisturizing materials to deposit and thereby 10 condition the skin. These special advantages allow the system to be mild withunexpectedly excellent lather vs. the known prior art cleansing kits. The present mild cleansing and moisturizing liquid cleanser with the mesh sponge is superior to the same cleansing and moisturizing liquid cleanser used with a regular sponge in terms of lather as well as overall acceptability by a majority of experimental users.
The cleaning polymeric mesh sponge can be prepared from readily available raw materials or with specially designed mesh materials. The polymeric mesh sponge is preferably prepared from extruded tubular netting mesh which has been prepared from special strong and flexible polymeric m~tPli:~l. Extruded tubular netting mesh of this type, and particularly those prepared from polyethylene, have been used for the covering of meat and poultry and are readily available in industry.
The polymeric mesh sponge comprises a plurality of plys of an extruded tubular netting mesh prepared from a strong flexible polymer, preferably of the group consisting of addition polymers of olefin monomers, and polyamides of polycarboxylic acids and polyamines, said plys of tubular netting mesh are folded upon itself numerous times to form a soft ball-like polymeric mesh sponge.
The tubes or stripes of netted mesh polymer can be securely attached by means of a nylon band or suitable closure. This type of polymeric mes sponge is disclosed in U.S. Pat. No. 4,462,135, July 31, 1984, to Sanford.
An example of a hand-held ball-like polymeric mesh sponge is disclosed in U.S. Patent No. 5,144,744, to Campagnoli, September 8, 1992. It is a diamond-mesh polyethylene sponge obtained from a number of netting tubes stretched over supports, joined and bound together at the center and then released from the supports.
Commercially available "polymeric mesh sponges" are sold by The Body Shop and Bynum Concept, Inc.

CA 0216~0~0 1998-04-20 The following are some specifications for suitable bath polyethylene polymeric mesh sponges:

Size Dia Tubes Ea. Length Total Length Wt gm

3" 2 60cm 120cm 15

4" 4 50 cm 200 cm 23

5" 4 80 cm 320 cm 37 One (1") inch = 2.54 cm.; 3" = 3 x 2.54 = cm.; 4" = 4 x 2.54 = cm.; etc.

FIG. 1 is a perspective representation of a diamond-mesh polymeric hand held ball-like bath sponge showing a rope handle 7 used in the present invention.
The ease with which a cleaning polymeric mesh sponge can be held in the hand forcleaning is shown in FIG. 2. A security band 13 holds the multi-layered netting mesh together to form the polymeric mesh sponge. The netting mesh that can be used in making the polymeric mesh sponge is illustrated in FIG. 3 wherein 21 represents the mesh in stretched position. The fine polymeric filaments used in making the netting are represented by 18 with 19 representing the spot bonding of the filaments to form the open mesh 20.
Two 2 netting tubes at 60 cm length each an be used to make a 3-inch ball sponge. They can be bundled m~ml~lly with a loop or rope to form a ball-like polymeric mesh sponge. Other designs such as rectangular gloves and washing implements made with the mesh material also work very well in the system of the present invention by increasing the lather of normally lower lathering cleansing and moisturizing liquid cleansers. Some examples of such cleaning implements are thesubject of two U.S. Patents in the name of Girardot et al., namely No. 5,412,830which issued May 9, 1995 and No. 5,465,452 which issued November 14, 1995.

THE CLEANSING AND MOISTURIZING LIQUID CLEANSER
The term "cleansing and moisturizing liquid" or 2-in-1 liquid cleanser as used herein includes lathering liquids and semi-solid creams which contain both a lathering ingredient and a moisturizing agent.
A plef~ d cleansing and moistllri~in~ personal cleansing liquid product comprises: (a) from about 0.1% to about 20% by weight of anionic surfactant; (b)from about 0.1% to about 20% of amphoteric surfactant; (c) from about 0.5% to about 25% by weight of a vegetable oil adduct, minors and; (d) balance water.

CA 0216~0~0 1998-04-20 The anionic surfactant and amphoteric surfactant together can comprise from about 0.5% to about 30% by weight of the composition; a preferred weight ratio of anionic surfactant:amphoteric surfactant is in the range from about l :S to about 20:1.
A preferred vegetable oil adduct can be made by Diels-Alder addition of a 5 conjugated, elaidinized form of the vegetable oil with acrylic acid, fumaric acid or maleic anhydride. The preferred adduct is maleated soybean oil. The compositionsprovide excellent-in-use and efficacy benefits including cleansing and lathering as well as improved mildness and skin conditioning Another pler~ d cleansing and moisturizing cleansing composition can 10 contain ingredients selected from the group consisting of: (a) 8% to 35% by weight polyol; (b) 35% to 70% by weight; preferably 40% to 65% water; (c) 5% to 20% by weight, preferably 7% to 19%, of mostly insoluble saturated (low IV of zero to lS) C8-C22 fatty acid potassium soap; (d) 0.1% to 7% by weight, preferably 0.5% to 5%, of free C8-C22 fatty acids; and (e) 0.5% to 5% by weight, preferably 0.7% to about lS 4.5% petrolatum, and mixtures thereof.
The polyol is selected from glycerin, glycerol, propylene glycol, polypropylene glycols, polyethylene glycols, ethyl hexanediol, hexylene glycols, and other aliphatic alcohols; and mixtures thereof. When propylene glycol is used as a moisturizer, it is used at a level of at least 5%. The polyols are preferably used at 20 levels of from about 10-30% by weight.
The liquid cleanser can contain from about 0.5% to about 15% by weight of a lipophilic emollient moisturizer selected from petrolatum; esters of fatty acids;
glycerin mono-, di-, and tri-esters; epidermal and sebaceous hydrocarbons such as cholesterol, cholesterol esters, squalene, squalane; silicone oils and gums; mineral oil;
25 lanolin and derivatives and the like; and mixtures thereof.
A preferred improved stable product with a moisturizing benefit is achieved with the incorporation of larger sized petrolatum particles into selected fatty acid/soap matrixes. The larger sized petrolatum particles will vary for a liquid or semi-solid.
The key is to select the fatty acid and/or soap matrix as exemplified herein, and mix in 30 the petrolatum using a minim~l controlled amount of shear to m~int~in larger petrolatum particles and achieve a homogeneous stable product, e.g., an improvedbenefit is also achieved in a semi-solid cleansing cream.
Any fatty acid matter (free and neutralized) used in the liquid cleanser preferably has an Iodine Value (I.V.) of from zero to about lS, preferably below35 10, more preferably below 3.

CA 0216~0~0 1998-04-20 LATHERING SOAP AND/OR SY~ ;llC SURFACTANT
The personal bath or shower body cleansing system preferably comprises from about 0.5% to about 30% by weight of lathering surfactant having a lathering grade at least as well as C16 alkyl glyceryl ether sulfonate. The preferred cleansing and5 moisturizing composition contains from about 1% to about 25%, preferably from about 5% to about 25% by weight, or 10-20% of a lathering soap and/or synthetic surfactant. A preferred surfactant is selected from mild soaps and mild synthetic surfactants and mixtures thereof. Examples of these mild soaps and surfactants are shown in the Examples herein.
The soaps are preferably those derived from essentially saturated hydrocarbon having chain lengths of from about 8 to about 22. It is preferred that the soap be the potassium salt, but other soluble soaps can be used. Some sodium, amrnonium, triethanolammonium, and/or mixtures thereof, are deemed acceptable, at least in potassium blends. The soaps are preferably prepared in-situ by neutralization of the corresponding fatty acids, but they may also be introduced as plerolllled soaps.
The preferred liquid soap is called a dispersoid because at least some of the fatty matter at the levels used herein is insoluble. The level of water in the compositions is typically from about 35% to about 70% by weight, preferably fromabout 40% to about 65%.
Another important attribute of the preferred liquid soap of the present invention is it is phase stable, particularly after storage.
An important attribute of the preferred soap personal cleansing product of the present invention is its rich and creamy lather.
An important component of liquid cleansers is a lather boosting surfactant.
The surfactant, which may be selected from any of a wide variety of anionic (soaps and nonsoap), amphoteric, zwitterionic, nonionic and, in certain instances, cationic surfactants, is present at said levels, namely 0.5% to 30% by weight of cleanser as hereinbefore described.
It is noted that surfactant mildness can be measured by a skin barrier destruction test which is used to assess the irritancy potential of surfactants. In this test the milder the surfactant, the less the skin barrier is destroyed. Skin barrier destruction is measured by the relative amount of radio-labeled water (3H-H2o) which passes from the test solution through the skin epidermis into the physiological buffer contained in a diffusate chamber. This test is described by T.J. Franz in the J. Invest.
De~ t-)1.7 1975, 64, pp. 190-195; and in U.S. Patent No. 4,673,525, Small et al., issued June 16, 1997, and CA 0216~0~0 1998-04-20 _ 9 _ which disclose a mild alkyl glyceryl ether sulfonate (AGS) surfactant based synbar comprising a "standard" alkyl glyceryl ether sulfonate ~ lul~. Barrier destruction testing is used to select mild surfactants.
The liquid composition preferably comprises a lathering surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, zwitterionic surfactants, amphoteric surfactants, and mixtures thereof.
The lathering surfactant is defined herein as a synthetic surfactant or llli~lul~;
thereof that when combined have an equilibrium surface tension of between 15 and50 dynes/cm, more preferably between 20 and 45 dynes/cm as measured at the 10 CMC (critical micell concentration) at 25~C. Some surfactant llli~lule can have surface tensions lower than of its components.
Some examples of good lather-enhancing, mild detergent surfactants include sodium or potassium lauroyl sarcosinate, alkyl glyceryl ether sulfonate, sulfonated fatty esters, and sulfonated fatty acids. Thus, a high lathering surfactant is defined 15 herein as one which lathers on the order of C16 alkyl glyceryl ether sulfonate or better. For a lather volume test, see U.S. Patent No. 5,264,145, to French et al., November23, 1993.
Numerous examples of other suitable surfactants are disclosed in the literature:they include other alkyl sulfates, anionic acyl sarcosinates, methyl acyl taurates, 20 N-acyl glut~rn~tes, acyl isethionates, alkyl sulfosuccinates, alkyl phosphate esters, ethoxylated alkyl phosphate esters, trideceth sulfates, protein condensates, mixtures of ethoxylated alkyl sulfates and alkyl amine oxides, betaines, sultaines, and nli~lules thereof. Included in the surfactants are the alkyl ether sulfates with 1 to 12 ethoxy groups, especially ammonium and sodium lauryl ether sulfates.
Many additional nonsoap surfactants are described in McCUTCHEON'S, DETERGENTS AND EMULSIFIERS, 1993 Edition, published by MC Publishing Co.
The above-mentioned surfactants can be used in the cleansing bath/shower compositions of the present invention. The anionic surfactants, particularly the alkyl 30 sulfates, the ethoxylated alkyl sulfates and mixtures thereof are preferred. More preferred are Cl2-CI4 alkyl anionic surfactants selected from the group consisting of sodium alkyl glycerol ether sulfonate, sodium lauroyl sarcosinate, sodium alkyl sulfate, sodium ethoxy (3) alkyl sulfate, and mixtures thereof.
Nonionic surfactants can be broadly defined as compounds produced by the 35 con(len~tion of alkylene oxide groups (hydrophilic in nature) with an organichydrophobic compound, which may be aliphatic or alkyl aromatic in nature.

CA 0216~0~0 1998-04-20 - . - 10 -The pH of the neat cleansing bath/shower liquid soap compositions herein is generally from about 7 0 to about 9 5, preferably from about 7.5 to about 9 as measured at 25~C. The pH of the liquid synthetic surfactant composition is about 4 to 8, preferably 4.5 to 7.
The cleansing and moisturizing liquid cleanser preferably has an apparent or neat viscosity of from about 500 cps to about 60,000 cps at 26.7~C, preferably 5,000 to 30,000 cps. The term "viscosity" as used herein means the viscosity as measured by a Brookfield RVTDCP with a spindle CP-41 at 1 RPM for 3 minlltes~ unless otherwise specified. The "neat" viscosity is the viscosity of the undiluted liquid cleanser.
Skin conditioner or moisturizer Skin conditioner or moisturizer deposition from a cleansing system is measured by one of two protocols, both are modeled after how skin cleansing products are typically used by consumers. One protocol is done "in vitro", while the second is done "in vivo".
In the in vitro protocol, a model skin substrate is used which is a collagen sheet that has a surface topography similar to human skin and has been pre-hydrated.
Small pieces of the substrates are mounted over flask openings to secure them for exposure to lather. The lather is generated in the palms of hands, the polymeric mesh sponge or other cleansing implement, using the following controlled procedure: one gram of product plus 3 ml of water for 10 seconds. The mounted substrate is thenexposed to the combined lather by overturning the flask and rubbing it on the palm of the hand, etc. This lathering process is continued for 10 seconds and, after allowing the lather to remain on the substrate for 5 seconds, it is rinsed with warm tap water for 10 seconds. The exposed skin substrate is then cut from the mount and dried prior to analysis. The analysis procedure is to submerge the substrate in 1: 1 ethanol:heptane if petrolatum is measured or another solvent suitable for other moisturizers and then analyze this extract by standard gas chromatographic methods.
The in vivo protocol is similar to the in vitro one described above, except the lather generated in the polymeric mesh sponge (or the palm of the hand) is applied to the opposite forearm. The time that the lather remains on the forearm is 30 seconds (compared to the 5 seconds on the collagen substrate). The deposited conditioner is then extracted by ~ll~pillg an open-ended glass cylinder to the forearm and adding the ~propliate solvent to this cylinder. As above, the extract is then analyzed according to standard gas chromatographic methods.

CA 0216~0~0 1998-04-20 The cleansing bath/shower compositions can contain a variety of nonessential optional ingredients suitable for rendering such compositions more desirable. Such conventional optional ingredients are well known to those skilled in the art andinclude, for example, preservatives such as benzyl alcohol, methyl paraben, propyl 5 paraben and imidazolidinyl urea; other thickeners and viscosity modifiers such as C8-Cl8 ethanolamide (e.g., coconut ethanolamide); pH adjusting agents such as citric acid, succinic acid, phosphoric acid, sodium hydroxide, etc.; suspending agents such as magnesium/aluminum silicate; perfumes; dyes; and sequestering agents such as disodium ethylenediamine tetraacetate.
If present, the optional components individually generally comprise from about 0.001% to about 10% by weight of the composition but can be more or less.
Optional thickeners are categorized as cationic; nonionic, or anionic and are selected to provide the desired viscosity. Suitable thickeners are listed in the Glossary and Chapters 3, 4, 12 and 13 of the Handbook of Water-Soluble Gums and Resins, Robert L. Davidson, McGraw-Hill Book Co., New York, N.Y., 1980.
The liquid personal cleansing products can be thickened by using polymeric additives that hydrate, swell or molecularly associate to provide body (e.g., hydroxypropyl guar gum is used as a thickening aid in shampoo compositions).
A suitable thickener is hydroxy ethyl cellulose, e.g., NatrosolR 250 KRTM sold by The Aqualon Company.
Another thickener is acrylated steareth-20 methylacrylate copolymer sold as Acrysol ICS-lTM by Rohm and Hass Company.
The amount of polymeric thickener found useful in the present compositions is about 0.1% to about 2% by weight, preferably from about 0.2% to about 1.0%.
The liquid cleanser can be made with from about 0.1% to about 5% by weight, preferably from about 0.3% to about 3%, of a skin moisturizing cationic polymer selected from the group consisting of: cationic polysaccharides and derivatives,cationic copolymers of saccharides and synthetic monomers, synthetic copolymers and cationic protein derivatives.
MAKING A SOAP-BASED CLEANSING AND MOISTURIZING LIQUID CLEANSER
Most methods of making cleansing and moisturizing liquid cleansers for the present invention use standard industry equipment. For example, a general process for a 6000 gram size batch using a 4.5 gallon jacketed tank agitated by a Lightning MixerTM (Model TS2010) fitted with a three prong propeller size agitator with blades CA 0216~0~0 1998-04-20 measuring one inch. However, mixing times will vary with equipment, batch size, etc.
1. The fatty acids (the oil phase), antimicrobial (if added), etc. is added to asanitary agitated and jacketed stainless steel vessel;
2. The oil phase is heated to about 80~C.
3. Polyol liquids (e.g., propylene glycol) and some surfactant are added to the heated oil phase.
4. In a separate container, a water phase is prepared cont~ining polymers, polyol liquids (e.g., glycerin), and water, and heated to 80~C with agitation.
10 5. The appro~iate base (e.g., potassium hydroxide) for an in situ soap formation is added and mixed into the oil phase.

6. Next, the water phase is added and mixed to the oil phase/soap vessel.

7. Glycol ester is melted and mixed into (6) at about 80~C.

8. Any additional surfactant is added to (7) at about 80~C.
15 9. The product of (8) is cooled to about 45~C at which time other minors such as preservatives and perfumes can be added.
10. The conditioner, e.g., petrolatum is added mixed to (9) at a temperature of between about 35~C to about 45~C or about or at a temperature below its melting point.
Alternatively, the product of Step 9 may stand prior to adding materials such as petrolatum. In case of the product st~n(lin~, the product of Step 9 is reheated to about 35~C., before the petrolatum is added.
In the method of making the product of this invention, the large petrolatum particle size is controlled by mix time and addition temperature. The shorter the mix time and the lower the temperature, the higher the proportion of larger petrolatum emollient particles is achieved.
A preferred mild liquid personal cleanser is disclosed in U.S. Patent Number 5,308,526 issued to Dias et al. on May 3, 1994.
The cleansing bath/shower compositions can contain a variety of nonessential optional ingredients suitable for rendering such compositions more desirable. Such conventional optional ingredients are well known to those skilled in the art andinclude, for example, preservatives such as benzyl alcohol, methyl paraben, propyl paraben and imidazolidinyl urea; other thickeners and viscosity modifiers such as C8-Cl8 ethanolamide (e.g., coconut ethanolamide); pH adjusting agents such as citric acid, succinic acid, phosphoric acid, sodium hydroxide, etc.; suspending agents such as 21650~i0 vvo 95/00116 PCT/USg4l06gl5 magnesiuml~lurrin~lm silicate; perfi~mes; dyes; and sequestering agents such as disodium ethylene~i~mine tetraacet~te.
MAKING A PREFERRED CLEANSING AND MOISllJR~7rNG LIQUrD CLEANSER
This method comprises the following steps:
a) Forming an aqueous phase comprising from about 0.1% to about 50~/~

The Mildness Protocol. Human subjects precondition their legs with an all ~ soap bar by washing twice a day for seven days. T,eatments are applied daily for 5 5 consecutive days. On each day, skin dryness grades can be taken before treatment (to measure chronic effects) and 60 minutes after treatment (measure acute effects).
On each day of the test, three 12.5 cm2 sites are treated on each of the subjects. Three tl~dtllle.lts are acsigned using a Latin square design, which takes into ~ccount baseline site-to-site differences in skin condition within each subject.

0 The trea~ s are:
I. A mild syndet bar.
II. A mild syndet bar plus a moisturizing lotion applied after washing.
m. A cleansing and moistl.r.Lin liquid cleanser, E~ample 6, used with a polymeric mesh sponge as shown in FIG. 1.
15 IV. A cleAric~ and moisturizing liquid cleanser, Example 6, used with a regular closed-cell sponge.
MILDNESS RESULTS
Treatment m ~p.~ ts the "System" of the present invention.
T~ea~ III is the 2-ilT-1 liquid cleanser Example 6 used with a "polymenc mesh 20 sponge" as show in FIG. 1.
Tred~ ..t II is a mild syndet bar plus a lotion. It is a very mild l,c~t..,~
because the lotion is applied directly to the skin a~er washing. This is not a 2-in-1 cl~nc;.~g and moisturizing trc~l...~ .ll but is used as a control. Note, however, that many people do not use a moisturizer a~er bathing or showering. The 2-in-1 25 cle~n~er is always milder than the mild syndet bar alone.
T,eA~ III, the 2-in-1 liquid cle~ncert Example 6, used with the mesh sponge, is si~ific~ntly milder than the mild syndet bar alone, i.e., without the lotion in chronic ~ n~ss and equal to it in acute rniklnPc~
