Description

FLUIDIZED POLYMER SUSPENSIONS OF
CATIONIC POLYSACCHARIDES IN POLYOLS AND
USE THEREOF IN PREPARING PERSONAL CARE COMPOSITIONS
FIELD OF THE INVENTION
This invention relates to fluidized polymer suspensions of cationic polysaccharides and their use in preparing personal care compositions, in particular, hair and skin care compositions.
BACKGROUND OF THE INVENTION
Cationic polysaccharides have been used in many personal care applications, e.g. shampoos, shower gels, hair styling compositions, skin creams and lotions, where they provide rheological properties to the compositions and desirable properties to the hair and skin.
In most cases cationic polysaccharides used in personal care compositions are utilized as dry powders. However, handling of powders is often accompanied by dusting which can be a cause of health and safety problems. Moreover, in the case of cationic polysaccharides the dusting problem is particularly troublesome, because the cationic material tends to adhere strongly to anionic surfaces. Furthermore, particulate polysaccharides are known to lump excessively when added to water, resulting in low rates of solution, and so special care must be taken when adding these materials to water to avoid lumping and gel formation. Often unacceptable gel levels remain in these solutions. For these reasons there has been a desire to develop cationic polysaccharide products that are readily dispersible in aqueous media by dispersing them in liquids with which they are immiscible but which are useful in particular personal care applications.
U.S. Patent No. 4,799,962 to Ahmed discloses particulate water-soluble polymers dispersed in liquid medium comprised of low molecular weight polyethylene glycol, water and high molecular weight polyethylene glycol. Dispersion of cationic polysaccharides is not disclosed.
U.S. Patent No. 5,487,777 to Lundan et al. relates to slurries of carboxymethyl cellulose comprising: a) 10 to 60 ~ of carboxymethyl cellulose, b) 40 to 60 % of water-soluble polyethylene glycol, the average molecular weight of which is below about 1,000, and c) 1 to 50 % of an inert powder or dispersion.
U.S. Patent No. 5,362,312 to Skaggs et al. discloses a polymeric fluid composition comprising: a) water-soluble polysaccharide, b) water-soluble polyethylene glycol or thickened polyethylene glycol, c) one or more viscosified polyol fluid components, and d) one or more viscosifying polysaccharides. The polysaccharides disclosed do not include cationic polysaccharides.
The solvation and solubility properties of various water-soluble polysaccharides can vary widely. Therefore, information on fluidized polymer suspensions of anionic and nonionic polysaccharides is of little utility in predicting what systems will be suitable for preparing fluidized poiymer suspensions of cationic polysaccharides. For this reason, the fluidized polymer suspensions of cationic polysaccharides disclosed herein are novel in composition and in their use in preparing personal care compositions.
SUMMARY OF THE INVENTION
In one embodiment of the invention a fluidized polymer suspension comprises: a) cationic polysaccharide, b) stabilizing agent, and c) water-soluble polyol that is not a solvent for the cationic polysaccharide.
In another embodiment of the invention a process of preparing a personal care composition comprises: a) providing a fluidized polymer composition comprising i) cationic polysaccharide, ii) stabilizing agent, and iii) water-soluble polyol that is a non-solvent for the cationic polysaccharide;

and b) mixing the fluidized polymer suspension with one or more personal care active ingredients.
DETAILED DESCRIPTION OF THE INVENTION
It is characteristic of the fluidized polymer suspensions of this invention that they are stable as made. By the term "stable as made" it is meant that the suspension does not immediately separate into two or more distinct layers when standing. In some instances, where the suspension will be used within a short period of time, it is sufficient that the suspensions be moderately stable, i.e., at least sufficiently stable so that the cationic polysaccharide remains dispersed or may be readily redispersed after standing for a short period of time, e.g. several hours or overnight. However, dispersed cationic polysaccharides tend to agglomerate upon settling into gels or solids which cannot readily be redispersed after standing for more than a few days (or in some cases much shorter periods of time). Therefore it is often preferred that the suspensions be storage stable over much longer periods of time since they will frequently be used in applications where they must be stored for periods of about one to six months. The fluidized polymer suspensions of this invention are stable as made, preferably stable for at least about one week, more preferably for at least about 8 weeks, and even more preferably for at least about 6 months.
Cationic polysaccharides for use in the invention include any naturally occurring cationic polysaccharide as well as polysaccharides and polysaccharide derivatives that have been cationized by chemical means, e.g.
quaternization with various quaternary amine compounds containing reactive chloride or epoxide sites. Example of such cationic polysaccharides include, but are not restricted to, cationic guar, hydrophobically modified cationic guar, cationic hydroxypropyl guar, cationic hydrophobically modified hydroxypropyl guar, cationic hydroxyethyl guar, cationic hydrophobically modified hydroxyethyl guar, cationic hydroxyethyl cellulose and cationic hydrophobically modified hydroxyethyl cellulose. Preferred cationic polysaccharides for use in the invention are cationic guar and cationic hydroxypropyl guar.
Methods for preparation of the cationic polysaccharides are disclosed in U.S. Patent numbers 4,663,159; 5,037,930; 5,473,059; 5,387,675;
3,472,840 and 4,031,307, all of which are incorporated herein by reference in their entireties.
Polyols used for preparing the fluidized polymer suspension of the invention are water-soluble, essentially non-solvents for the cationic polysaccharides (i.e., the cationic polysaccharides are soluble at a level of no more than about 5 % ) and preferably liquids. Examples of such polyols include, but are not restricted to polyethylene glycol, propylene glycol, polypropylene glycol, diethylene glycol, glycerine and ethylene glycol. The preferred polyol is polyethylene glycol.
Polyethylene glycol, also called "polyoxyethylene" , "poly(ethylene oxide)", or "polyglycol" is a well known condensation product of ethylene glycol having the formula H(OCH2CH2-)"OH. Polyethylene glycols are commercially available in several grades and molecular weights. Preferred polyethylene glycols for the invention have a relatively low molecular weight of between about 150 and 1,000. More preferably the molecular weight is from about 200 to about 700, and most preferably from about 250 to about 600.
In the fluidized polymer suspensions of the invention, the cationic polysaccharide is preferably from about 10 to about 65 wt. rb and the polyol from about 35 to about 90 wt. ~ of the total weight of the fluidized polymer suspension. More preferably the cationic polysaccharide is from about 15 to about 60 wt. % and the polyol from about 40 to about 85 wt. ~ . Most preferably the cationic polysaccharide is from about 20 to about 50 wt. ~ and the polyol from about 50 to about 80 wt. % of the fluidized polymer suspension.
The other ingredient necessary in the fluidized polymer suspensions of the invention is a stabilizing agent, which will generally be present at a level of from about 0.5 to about 3 wt. % of the total weight of the suspension. The stabilizing agents are organic or inorganic materials which can be dispersed or dissolved in the polyol medium. Preferred stabilizers are silica, mineral pigments, organic pigments, crosslinked polymers and copolymers of acrylic acid, cellulose ethers and mixtures thereof. More preferred are silica and mineral pigments. Examples of mineral pigments include, but are not limited to calcium carbonate, titanium dioxide, clay, talc and gypsum. Preferred cellulose ethers for use as stabilizers are carboxymethyl cellulose and hydroxypropyl cellulose. The most preferred stabilizer is silica.
The fluidized polymers suspensions may optionally contain water. If water is used, the amount should not be so great that the suspended cationic polysaccharide swells and forms a gel. Water is generally used in an amount such that the ratio of cationic polysaccharide to water is not less than about 5:1.
Fox preparation of the fluidized polymer suspensions of the invention preferably the polyol is added to a high shear mixing device, and then the appropriate stabilizing agent is added. The mixture is stirred for a sufficient time to disperse the stabilizing agent, and the cationic polysaccharide is added. Further stirring is carried out until dispersion is complete. If water is utilized as a component of the fluidized polymer suspension, it can be added with the cationic polysaccharide or the stabilizing agent. However, the order of addition of the ingredients has no effect on the properties of the suspension.
The fluidized polymer suspensions of this invention find use in the formulation of personal care products, particularly hair and skin care compositions. Use of fluidized polymer suspensions of the cationic polysaccharides in place of dry powdered cationic polysaccharides has the advantages that the dusting, low rate of solution, lumping and gel formation of the powders is avoided.
Examples of personal care products of the invention include, but are not limited to shampoos, hair conditioners, combination shampoo-conditioners, sun screen products, shower gels, soaps, hair styling products, hair colorants, deodorants, antiperspirants, moisturizing lotions and the like.
The personal care products of the invention generally will comprise, in addition to the fluidized polymer suspension, some active component which provides benefit to the hair or skin. Such materials may include moisturizing agents, anti-perspirants, anti-bacterials, sunscreen agents, cleaning agents, hair conditioning agents, hair styling agents, anti-dandruff agents, hair growth promoters, hair dyes and pigments, soaps and perfumes.
