Description
~25~
Background of the Invention .
Antiperspirant products are frequently produced in stick form, such as wax sticks, soap gel sticks, and pressed powder sticks. A wax stick, in addition to the antiperspirant active ingredient, is composed of waxes and esters and contains a relatively high percentage of a solvent. Wax stickshave certain inherent disadvantages in that the waxes have a ten-dency to stain clothing~ and the wax residue cannot be removed from the clothing by normal washing procedures. As the wax stick contains a high proportion of solvent, the solvent will evaporate if the stick is unsealed and exposed to the atmosphere, thereby resulting in shrinkage and'dog-boning" of the stick, with a resulting unattractive appearance.
As the wax stick has a relatively high propo~tion of solvent, this reduces -the proportion of active ingredient that can be included in the stick, limitinq the active ingredient to a maximum percentage of about ~0%.
Soap gel anti-perspirant sticks have also been used in the past.~ The conventional soap gel system includes sodium ~; 20 stearate and a low molecular weight alcohol, such as ethanol, ; as well as an anti-perspirant active ingredient in a maximum amount of about 20~. In addition, soap gel sticks have nor-mally used calcium carbonate as a filler. Because of the hygros-~ copic nature of the ingredients, the product has a tendency to -~ 25 absorb water, expand and crack. Furthermore, the calcium " carbonate filler tends to neutralize the anti-perspirant, which is normally aluminum chlorohydra-te, thereby rendering the anti-perspirant salt ineffective. As a further disad~antage, the alcohol will evaporate ir the stick is exposed to the atmos-phere, causing shrinking and "dog-boning" of the stlck.
s~c:~
Attempts have also been made in the past to provide a dry, pressed powder, anti-perspirant stick. In sticks of this type, the active ingredient is incorpora-ted with an inert filler and binder and the dry mixture is compressed or extruded at high pressure into stick form. The compression operation is slow and requires a dwell of several minutes at hi~h pressure, making the process unsatisfactory from a commercial standpoint.
Extrusion of the dry mixture is particularly difficult due to the abrasive nature of the dry powdered mixture. Further, in both compressing and extruding processes, the anti-perspirant active ingredient is damaging to the expensive processin~
equipment.
Summary of the Invention -- . _ .
The invention is directed to a powder stick for ` 15 topical application, such as an anti-perspirant stick, or a cosmetic stick, which is produced without the application of super-at-mospheric pressures~ In preparing the stic~, the active ingredient, a Eatty alcohol and a finely divide~ inert filler are mixea with li~uid siloxane at an eleva~ed temperature to ~orm a slurry. The slurry is then molded into a stick form at atmospheric pressure, and after molding, the stick is dried in air to evaporate a major portion of the siloxane.-The resulting powder stick is hard and firm for stickstrength, but yet will not glaze over during application to the skin.
As the dried stick has a relatively low residual propor-tion o~ the siloxane solvent, the stick is stable and will retain its shape and consistency, even if unsealed and exposed -to the atmosphere for extended periods of time.
3Q The liquid siloxane serves to disperse the fatty alcohol .
. .
5~9 and results in a uniform distribution of the fatty alcohol through-out th~ filler, thereby providing uniform characteristics for the.
stick throughout its entire cross-section. The uniform dis tribution of the ingredients results in the stick being resistant S to humidity absoxption and prevents degradation of the stick : under high.humidity conditions. ' ~ , As the siloxane is substantially entirely evaporated prior to packaging, the stick contains a high proportion of powder form ingredients, generally up to 90%.
Other objects and advantages will appear in the course of the followin~ description.
Description of the Preferred Embodiment The powder stick of the invention is pre~ared from a slurry having the following general formula-tion in weight percen-t:
Finely divided inert fi:ller 7.0~ to I0%
Fatty alcohol 5% to 30%
Siloxane 25% to 60%' When preparing an anti-perspirant stick ac~ording to the invention, the slurry has the following formulation in weight percent:
Finely divided inert filler 66% to :-3%
Anti-perspirant active ingredient 10% to 35%
Fatty alchol 4% to 12 Siloxane 20% to 50%
When preparing deodorant sticks according to the invention the slurry has the following formulation in weight percent:
Finely divided inert filler 69.9% to --5%
Fatty alcohol 5% to 30%
Deodorant active ingredient 0.1% to 5%
Siloxane 25% to 60 s~
In preparing a costmetic stick according to the invention, such as an eye shadow stick or blush stickl the slurry used in preparing the stick h~s the following formulation in weight percent:
Finely divided inert filler 75% to .3%
Fatty alcohol 4% to 12~
Cosmetic coloring materials 1% to 35%
Siloxane 20% to 50%
~ The finely divided filler can take the form of materials .~ 10 such as aluminum hydroxide, koalin, talc, mica, corn starch, calcium carbonate, silicon dioxide, calcined clay, barium sulfate, .
aluminum oxide, aluminum silicate, and the like.
The fatty alcohols serve as a binder for the system .; and contain from 12 to 22 carbon atoms in the molecule. The : 15 fatty alcohol can take the form of cetyl alcohol, stearyl alcohol, ; and the like.
The siloxane is normally a l.iquid at room temperature.
Chemically it is composed primarily of two components-: D4 cyclo- :
dimethicone and D5 cyclodimethicone. The D4 component repres-:1 20 ents the ma~ority with the D5 being a minor constituent.

When preparing an anti-perspirant stick, the anti-perspirant active ingredient can be aluminum chlorohydrate, aluminum hydroxychloride, zirconium hydroxy chloride, aluminum chloride, or other acceptable anti-perspirant materials.
When forming a deodorant stick, the deodorant active ingredient can take the form of:
(A) - 2,4,4' - trichloro - 2'hydroxydiphenyl ether (B) - 1,-(2-hydroxyethyl) carbamoyl methyl pyridinium chloride laurate (C) - Benzenthonium chloride (D) - Zinc phenolsulfonate (E~ - Aluminum chlorohydroxide When preparing a cosmetic coloring stick, such as an eye shadow stick or blush stick, the cosmetically acceptable coloring materials can take the form of titanium dioxide, ferric ferrocyanide or ferric ammonium ferrocyanide, iron oxides, ultramarines, chromium oxide, chromium hydroxide, pearlescents, organic dyes and lakes.
In addition to the above ingredients, the slurry can also contain small amounts, up to 2% by weight, of a fatty acid ester containing from 12 to 22 carbon atoms, such as iso-propyl myristate or isopropyl palmitate, which prevents dusting of the stick; and/or magnesium stearate which aid in preventing glazing ~.
565~
of the stick; and/or a preservative such as methyl paraben or propyl paraben; or perfumes.
To prepare the powder stick of the învention, the fatty alcohol is dispersed in the liquid siloxane at a tempera-ture of 60C to 70C. The remaining ingredients,such as thefiller, active ingredient and other additives,are then mixed into the liquid dispersion to provide a slurry. The slurry is then poured ~y gravity at atmospheric temperature into a case or mold. The slurry at this time has a temperature slightly above the solidif~cationtemperature of the siloxane and generally in the range of about 50C to 60C. On cooling, the slurry will solidify to form a solid stick.
The stick is then exposed to air movement, either by blowing air over the molded product or subjecting the molded product to a vacuum. In practice, the drying air preferably l has a relative humidity of about 15% and is at a temperature in the range of about 25C to 30C~ The air movement serves to evaporate a major portion of the siloxane from the molded product so that the dried product has a residual siloxane content ~f less than 2% by weight. While it is possible to evaporate the entire siloxane content, it is normally uneconomical to go beyond the 2~ level though this can be accomplished by varia-tions in relative humidity and atmospheric pressure.
As ~he siloxane is a relatively expensive material, it is preferred to carry out the drying in a closed chamber or hood so that the siloxane vapor can be recovered for reuse through use of a condensing unit.
The resulting dried powder stick has excellent strength yet provides adequate pay-off on the skin and is not so hard that it will glaze over after several applications to the skin-S65~
Through use o~ the siloxane solvent, the powdered ingredients and the fatty alcohols are uniformly distribu~ed throughout the stick, therehy insuring the same level of effect-iveness for each application to the skin.
As the dried product contains only a minimum propor-tion o~ the evaporable siloxane, and waxes and fatty esters, the product is stable even if exposed to the atmosphere, wili remain effective over a substantial period of time and can be removed from fabric or clothing by machine washing with little or no stain effect.
The powdered stick of the invention is extremely resistant to humidity conditions and will not decompose or crumble under high humidity conditions.
As a further advantage, the product has a low level of dusting so as to be attractive to the consumer during use.
