Abstract: The invention comprises a cosmetic composition which is a translucent to clear stick having low tack. The cosmetic sticks are formed by combining (a) from 5.0-50.0 weight percent of a silicone fluid phase which comprises at least one hydroxy functionalized silicone fluid, at least one stabilizing agent and, optionally at least one additional silicone material; (b) from 40-95 weight percent of a gellant/solvent phase which comprises a mixture of dibenzylidene sorbitol and at least one solvent such as a polyhydric alcohol (for example, propylene glycol); and (c) an effective amount of at least one active ingredient.

Description: COSMETIC COMPOSITIONS WITH DIBENZYLIDENE SORBITOL AND FUNCTIONALIZED SILICONES This invention relates to cosmetic compositions in the form of solid sticks which are based on using dibenzylidene sorbitol as a gellant for sticks, especially propylene glycol based sticks, in combination with a functionalized silicone fluid whereby a significant reduction in tackiness is provided. The cosmetic compositions of the invention may be used to formulate deodorant and/or antiperspirant sticks, especially those which are translucent to clear in appearance. BACKGROUND OF THE INVENTION Dibenzylidene sorbitol (also called dibenzaldehyde monosorbitol acetal, or dibenzyl monosorbitol acetal or dibenzylidene monosorbitol acetal) and derivatives thereof such as those which are substituted on one or both of the aromatic rings with a fluorine or methoxy group and those which have the sorbitol portion replaced with other reduced sugars such as xylitol or ribitol as described in U.S. Patent 5,609,855 assigned to Procter & Gamble (collectively referred to as dibenzylidene sorbitol or "DBS") may be used in various food and cosmetic applications. For cosmetic uses the more interesting ones are those focused on obtaining a translucent or clear product. While dibenzylidene sorbitol is stable in alkaline or neutral media, such compounds are not stable in acicic media. In an acidic environment, such as in the presence of acidic antiperspirant materials, and when in the presence of even small amounts of water, the dibenzylidene sorbitol deteriorates and breaks down. Also, the use of DBS sometimes causes problems in the aesthetics of cosmetic products or problems with structural properties. Accordingly, there is a need to find a way to form products containing DBS which are stable and which have acceptable aesthetics. The use of DBS requires the use of polyhydric alcohols such as propylene glycol as a solvent if a clear, transparent product is desired. The high propylene glycol content, when combined with aluminum salts which are included in antiperspirant compositions for wetness control, contribute to undesirable tackiness or a sticky feel for these products when applied to the axilla region of the body. DBS clear antiperspirant sticks were first formulated in the late 1970's. There have been continued technical efforts to reduce the negative sensory attributes. Some of these efforts have focused on alternative solvents to replace a portion of the propylene glycol with organic esters known in the art as emollients. This creates a further problem since many of these emollients are either unsafe for personal care products or do not achieve acceptable aesthetics. For formulating personal care products the incorporation of silicone fluids is known in the art. Silicone fluids such as cyclosiloxanes (for example, DOW CORNING® 244 and 245 Fluids) are used in some major commercial products. Silicone fluids are used because of their low tackiness, superior glide and skin-feel properties. However, silicone fluids are difficult to introduce into DBS based cosmetic stick products such as antiperspirants because they are not good solvents for DBS and they are not readily compatible with propylene glycol and many organic esters or emollients. Some of the efforts on each of these fronts are described as follows. For example, some efforts have focused on the stability of DBS. United Kingdom Patent GB 2 280 1 1 1 assigned to Union Camp Corporation, describes a gel stick composition comprising a dihydric alcohol as a primary solvent, a co-solvent such as low molecular weight polyethylene glycol. water and/or glycerine, a buffering agent and DBS as a gelling agent.

U.S. Patent Number 4,722,835 to Schamper, et al also discloses antiperspirant gel stick compositions gelled with dibenzyl monosorbitol acetal and containing an acidic antiperspirant compound, and also containing a stabilizer for the gel. This patent teaches that the compositions include a solvent which is a small, polar organic compound, as discussed previously in connection with U.S. Patent Number 4,719, 102: dibenzyl monosorbitol acetal: an antiperspirant-active compound: and a gel stabilizer such as zinc oxide, calcium acetate, magnesium oxide, calcium carbonate, calcium hydroxide, magnesium carbonate, sodium carbonate, zinc carbonate and potassium carbonate. This patent discloses that these basic metallic salt gel stabilizers can stabilize the gel. even at high temperatures.

There continue to be efforts to formulate improved cosmetic compositions especially sticks which have translucent to clear appearance and which have aesthetically acceptable properties. U.S. Patent Number 5,500,209 to Ross et al describes a gel or stick composition for reduction of body malodor using a polyamide gelling agent. This composition is stated to have good stability and to be able to provide a clear antiperspirant or deodorant product with good structural integrity. U.S. Patent Number 5,603,925 to Ross et al teaches the use of a polyamide gelling agent in an antiperspirant product. The composition uses a glycol-free solvent system to reduce the problems of tack and achieve more acceptable properties. U.S. Patent Number 4,440.742 to Marchner discloses a stable cosmetic stick deodorant without the use of bacteriostats and comprising a polyhydric alcohol (such as propylene glycol) solidified by a fatty acid soap and containing from 0.1-70% alkali metal bicarbonate.

There still remains a need, however, to develop translucent, preferably clear, cosmetic products which provide reduced tack in a DBS product. Thus, it is an object of the present invention to provide a cosmetic composition which comprises DBS and which provides reduced tack when applied to the skin. It is a further object of the invention to provide cosmetic compositions contammg DBS which can be used to torm deodorant and/or antiperspirants which are translucent to clear. It is yet another object ot the invention to provide cosmetic compositions which enhance the compatibility ot DBS in propylene glycol systems which also contain silicone fluids These and other objects ot the invention will be apparent trom the following description ot the invention Summary of the Invention The mvention comprises a cosmetic composition which is a translucent to clear stick having low tack The cosmetic sticks are formed by combining the components described below to torm a two phase system. These components, in weight percent based on the total weight ot the composition, are: (a) trom 5.0 - 50.0 weight percent ot a silicone fluid phase (as the first or internal phase) which comprises at least one hydroxy tunctionahzed silicone fluid, at least one stabilizing agent and, opuonally at least one additional silicone material: (b) trom 40 - 95 weight percent ot a gellant/solvent phase (as the second or external phase) which comprises a mixture ot dibenzylidene sorbitol and at least one solvent such as a polyhydπc alcohol (tor example, propylene glycol); (c) an effective amount ot at least one active ingredient; and (d) optionally one or more members selected trom the group consisting of emollients, fragrances, colormg agents, etc.. wherem the materials hsted in parts (c) and (d) may become part ot either ot the phases described in part (a) or part (b) Brief Descnption ot the Drawings Figure 1 shows data trom a Forearm Flex Test done with an antiperspirant sample trom Example 5 formulated with DBS and silanol (Ime with circles) and a commercial deodorant product formulated with DBS but without silanol (line with squares) The tack profile shows that the formulation ot Example 5 is 5- 10% less tacky than a commercial deodorant stick which contams no antiperspirant. This is significant because the addition ot an antiperspirant salt creates increased problems with tack The ability ol an antiperspirant formulation to perform as well or better than a deodorant stick which does not contain an antiperspirant salt is a significant development Figure 2 shows data trom a Forearm Flex Test done with an antiperspirant sample trom Example 5 formulated with DBS and silanol (Ime with circles) as compared to a clear, commercially available antiperspirant stick iormulated with DBS but without silanol (Ime with squares) The tack profile ot the formulation ot Example 5 is significantly less tacky (on the order ot 65-70% less) than the commercial product This result demonstrates the superiority ot the present invention Detailed Description ol the Invention The compositions ot this invention are made by combining the components described above in a two phase system to torm a stick cosmetic composition The first phase is the silicone fluid phase and comprises at least one hydroxy tunctionahzed silicone fluid and at least one stabilizmg agent Compounds ot Formula I are described as follows and can be used with or without additional silicone fluids Suitable tunctionahzed silicone fluids are hydroxy functional fluids with the general structure ot Formula I. (R 1 -Si-O 3 /2)a-( 2 2-Si-O 2 / 2 ) b -((HO)R 3 2 -Si-O,/ 2 )c Formula I where each of R 1 , R 2 , and R'. may be alike or different and are each independently selected from the group consisting of C1-C4 straight chain alkyls (especially methyl): a is a number in the range of 0- 10, with particular values of "a" being 0 for linear compounds and 1- 10 for branched compounds (for example 6-8): b is a number in the range of 0-10.000, with particular values of "b" being 4-6000: c is a number in the range of 1-10, with particular values of "c" being 2 when the compound is linear and at least 3 when there is branching: provided that a and b cannot both equal zero at the same time. It is to be recognized that a. b, and c are average values (including whole numbers and fractions) and mixtures of compounds with various values for a, b, c, R 1 , R 2 , and R' may also be used. Examples of compounds of Formula I include: (a) linear polydimethylsiloxanediols where a = 0, b = 4 - 6.000 (for example, an average value of 4, 40 or 6,000); (b) linear polydimethylsiloxanediols where a = 0. b = 4 - 1.000 and c = 2: (c) multifunctional branched siloxanes where a = 1 - 2. b = 0 - 1 ,000, and c = 3 - 4; (d) linear polydimethylsiloxanediols where a = 0, b = 40 and c=2; (e) multifunctional branched siloxanes where a = 1 , b = 16, and c = 3; (t) multifunctional branched siloxanes where a = 1- 2. b = 10 - 1 ,000, and c = 3- 4; (g) mixtures of the particular compounds described in parts (a) - (f). for example, mixtures wherein the average structure of the mixture is described by a = 0.1, b = 4- 6000. and c = 2-7: and (h) two component mixtures of the particular compounds described in parts (a) - (f) wherein one component is 0.1 - 99.9% of the composition and the other component is the remainder to 100%. For each of the groups listed as (a) - (1) above, particular examples of the compounds are when each of the R groups is selected to be methyl. Also, for any of the groups (a) - (g), additional silicone fluids such as dimethicone may be added, for example in amounts of 0.1 - 90% functionalized silicone and 10 - 99.9% silicone fluid or fluids. One particular group of compounds of Formula I are linear silanols of Formula IA, especially when b = 40: HO-(R 3 ) 2 Si-O - ((R 2 ) 2 Si-0)b - Si-(R 3 ) 2 OH Formula IA Some of the compounds of Formula I may be purchased commercially. For methods of making other compounds of this invention descriptions of suitable methods may be found in the literature for example, U.S. Patent 5,302,382 to Dow Corning; U.S. Patent 3,441.537 to Stauffer Chemical Company: and Noll. W., Chemistry and Technology of Silicones, (Academic Press, Inc. Orlando. Florida 1968) especially at pages 190-196 and 239-245, all of which are incoφorated herein by reference. While the hydroxy functionalized silicones described above are preferably selected to have a viscosity that does not require additional silicone materials (for example, having a viscosity in the range of up to 60.000 centistoke (cst), it is possible to use compositions which are a blend of hydroxy functionalized silicones having higher viscosities such as those having a high viscosity (>500.000 centistoke) dimethiconol in dimethicone where the dimethicone has a viscosity in the range of 5-350 centistoke (for example, DOW CORNING® 1403 Fluid). For high viscosity functionalized silicones (for example, the silicone gums), and for the purpose of facilitating its handling and processing, these materials are generally provided as blends with another volatile or non-volatile low viscosity silicone such as CYCLOMETHICONE. or a non- volatile linear silicone fluid having a viscosity of about 5 to 350 centistoke. Such dimethyl silicone polymers terminated with hydroxyl groups have been assigned the INCI name "DIMETHICONOL" by The Cosmetics, Toiletries and Fragrance Association, Inc.. Washington, D.C. (CTFA). Blends of such silicone gums with a volatile low viscosity cyclic silicone have been assigned the INCI name "CYCLOMETHICONE (and) DIMETHICONOL" by the CTFA. Other blends of such silicone gums with a non-volatile low viscosity linear silicone have been assigned the INCI name "DIMETHICONE (and) DIMETHICONOL" by the CTFA. The DIMETHICONOL content of such blends is typically in the range of about 12 to 14 percent by weight, and the blend viscosity may range trom 500 to about 20,000 centistoke, generally in the range of about 4,000 to 5,000 centistoke. Other volatile low viscosity methylsiϋcone fluids are described in U.S. Patent Number 5,302,382 to Kasprzak, incorporated by reference herein. Examples of methylsilicone fluids having viscosities of less than about one hundred centistoke measured at twenty-five degrees Centigrade, preferably less than about five centistoke and also methylsilicone fluids having a viscosity in the range of 1 - 350 centistoke are disclosed. One group of methylsilicone fluids is volatile low viscosity methylsilicone fluid containing dimethylsiloxane units and. optionally, trimethylsiloxane units. Representative compounds are cyclopolysiloxanes of the formula r(CH ) 9 SiO] and linear short chain siloxane compounds of the formula (CHZ SiO[(CH ) 2 SiO] Si(CH ) 3 , in which x is an integer having a value of from three to ten, (especially 4-6) and y is an integer having a value of from zero to about four. The cyclopolysiloxanes have been assigned the INCI name "CYCLOMETHICONE" by The Cosmetics. Toiletries and Fragrance Association, Inc.. Washington, D.C. (CTFA). The silicone fluid phase can also, optionally, include other silicone materials even when the purpose is for reasons other than viscosity modification. Particular silicone fluids are selected so that a stable silicone/glycol suspension is formed when the two phases are combined and mixed. Such materials can include, for example, other silicone fluids such as polydimethylsiloxanes, polydiethylsiloxanes. and polymethylethvlsiloxanes, having a viscosity in excess of 350 centistoke and up to 2.500,000 centistoke, preferably, 350- 10,000 centistoke. Further examples include cetyl dimethicone copolyol, dimethicone copolyol (such as DOW CORNING® 2501 , Q2-5220 and 5324 products); a mixture of cyclomethicone and dimethiconol (such as DOW CORNING® 1401 product); a mixture of dimethicone and dimethiconol (such as DOW CORNING® 1403 product): cetyl dimethicone (DOW CORNING® 2502 product); and stearyl dimethicone (DOW CORNING® 2503 product). A stabilizing agent is also included in the silicone phase. This stabilizing agent may be selected from several types of groups. One such group is silicone polyether surfactants having a hydrophilic/lipophilic balance ("HLB" value) compatible with the solvent and the silicone phase particularly to form a stick composition. For example, if propylene glycol is used as the solvent a polyether surfactant with an HLB value of 1- 10 is preferred (for example, DOW CORNING® 3225 C Formulation Aid (HLB = 1.7) DOW CORNING® 190 Surfactant (HLB = 5)). If tri- and/or tetrapropylene glycol is used as the solvent a polyether surfactant with an HLB value in the range of 5- 10 is preferred. For example, a cosmetic composition may be formed wherein the stabilizing agent is a member of the group consisting of silicone polyether surfactants having a hydrophilic/lipophilic in the range of 1-10, and the solvent comprises greater than 50% by weight of propylene glycol, dipropylene glycol, tri propylene glycol or tetrapropylene glycol. A particular siloxane polyether has the following Formula II: (R a ) 3 - SiO - [(R a ) 2 -SiOjV - [Si(R a ) (R b -O-(C 2 H 4 O) p -(G-H 6 O),R c ) O] y -Si-(R a ) 3 Formula II wherein R a is an alkyl group of one to six carbon atoms: R is the radical -C m H 2m -; R c is a terminating radical which can be hydrogen, an alkyl group of one to six carbon atoms, an ester group such as acyl, or an aryl group such as phenyl: m has a value of two to eight; p and s have values such that the oxyalkylene segment -(C 2 H-*O) p -(C 3 H 6 θ),- has a molecular weight in the range of 200 to 5,000: the segment preferably having fifty to one hundred mole percent of oxyethylene units -(C 2 H 4 O) - and one to fifty mole percent of oxypropylene units -(C HβO) s -; x has a value of 8 to 400: and y has a value of 2 to 40. Preferably R is a methyl group. R' is H: m is preterably three or tour whereby the group R b is most preterably the radical -(CH 2 ) 3 -; and the values ot p and s are such as to provide a molecular weight ot the oxyalkylene segment -(C 2 H O) p -(G-H 6 O),- ot between about 1 ,000 to 3,000 Most preterably p and s should each have a value ot about 18 to 28. A second siloxane polyether has the Formula III: (R a ) 3 - SiO - [(R a ) 2 -SiO] x - [Si(R d ) (R -O-(C 2 H 4 O) p -R c ) O] y »Si-(R a ) 3 Formula III wherem R a is an alkyl group ot one to six carbon atoms. R b is the radical -C m H 2 „,-: c i a terminating radical which can be hydrogen, an alkyl group of one to six carbon atoms, an ester group such as acyl, or an aryl group such as phenyl: m has a value of two to eight; p has a value ot 6 to 16: x has a value ot 6 to 100: and y has a value ot 1 to 20 It should be understood that in both Formulas II and III shown above, that the siloxane-oxyalkylene copolymers ot the present mvention may, in alternate embodiments, take the torm ot endblocked polyethers in which the linking group R b . the oxyalkylene segments, and the terminating radical R l occupy positions bonded to the ends of the siloxane chain, rather than bemg bonded to a silicon atom in the siloxane cham. Thus, one or more ot the R a substituents which are attached to the two ternunal silicon atoms at the end ot the siloxane cham can be substituted with the segment -R -O- (C 2 H 4 O) P -(C^H 6 O) s -R or with the segment -R -O-(C 2 H 4 θ) p -R c In some mstances. it may be desirable to provide the segment -R b -O-(C 2 H 4 O) p -(C^H 6 O) s -R t or the segment - R b -O-(C2H O) p -R c at locations which are in the siloxane cham as well as at locations at one or both ot the siloxane chain ends Mixtures of silicone polyethers can also be used. Such mixtures include components which themselves met the HLB criteria described above or which, in combination, meet the HLB criteria described above. In one particular embodiment the silicone fluid phase comprises at least a portion of a sihcone polyether surfactant to stabilize the cosmetic composition when it contains an antiperspirant active material. In antiperspirant compositions the polyether component is preferably used in an amount of 1.0 - 25.0 weight percent. These sihcone polyethers can be added to the sihcone fluid phase before the mixing of the first and second phases or the polyether can be added to the combined mixture at the end of the process during the cool down cycle. Examples of suitable sihcone polyethers include DOW CORNING® 190 Surfactant (HLB of 5.6), DOW CORNING® 193 Surfactant (HLB of 12. - 12.45), DOW CORNING® 2501 Cosmetic Wax (HLB of 19.0), DOW CORNING® 5200 (HLB of 6.83). DOW CORNING® 5324 (HLB of5.0), DOW CORNING® 3225C Formulation Aid. and DOW CORNING® 5220 (HLB of 71.7). The stabilizing agent can also be a high refractive index (greater than 1.4325) modifier, for example a member selected from the group consisting of isopropyl myristate, isopropyl palmitate. mineral oil, oleyl alcohol sorbitol, glycerol. octyl salicylate, octylmethoxycinnamate; phenyl siloxanes of Formula IV: (R 5) 3 Si - O - [(R 6 ) 2 Si - 0] p - Si (R 7 ) 3 Formula IV where R\ R 6 and R 7 are each independently selected from methyl and phenyl, and p is a number in the range of 0 - 10 (for example a trimethylphenylsiloxanes such as DOW CORNING® 556 Fluid; and polydiphenylsiloxanes , for example, tetramethyl tetraphenyl trisiloxane such as DOW CORNING® 704 Fluid and trimethyl pentaphenyl trisiloxane such as DOW CORNING® 705 Fluid).

The amount ot antiperspirant active material mcorporated in the stick composition ot the present invention is preferably, an antiperspirant effective amount: that is, an amount to reduce the flow ot perspiration trom the location (tor example, axillary region of a human) to which the antiperspirant is apphed. For deodorant products a level of from 0.5 - 20%, more particularly 0.5 - 5.0% by weight based on the entire weight of the composition is used. For an antiperspirant product an amount of 5.0-25%, particularly 5-20%, even more particularly 7- 15%, and especiahv 7- 12% by weight based on the total weight of the composition may be used. The amount of antiperspirant material utilized is dependent on the efficacy of the specific antiperspirant material, as well as a maximum amount which avoids a reduction in clarity of the final product. For embodiments of the invention which contain an antiperspirant (either at a level denominated "deodorant" or at a level denominated "antiperspirant") it is preferred that a stabilizing agent also be included Examples of suitable stabilizing agents include cosmeticahy acceptable alkali metal salts, bases, amines and other nitrogen containing compounds, particularly guanidine carbonate (described in U.S. Patent Number 5,490,979).

Triclosan. can illustratively be included in an amount of from 0.1 % to about 0.5% by weight, of the total weight of the composition. The fourth component used to make the compositions of the invention is the remainder and portion comprising one or more of the following optional ingredients: emollients, fragrances, coloring agents and ingredients having a lower refractive index than 1.4325 such as water, ethanol, wherein the materials listed in this fourth component may become part of either the silicone phase or the gellant solvent phase. Emollients may be selected from the group consisting of emollient oils such as a hquid mixture of hydrocarbons which are hquids at ambient temperatures (such as petroleum distillates and hght mineral oils), mineral oh, peanut oh, sesame oh, avocado oh, coconut oh, cocoa butter, almond oh, safflower oh. corn oh, cotton seed oh, castor oh, olive oh, jojoba oh, paraffin oh, cod hver oh. palm oh, soybean oh, wheat germ oh, linseed oh, and sunflower seed oil: fatty acid esters such as isopropyl myristate, isopropyl palmitate, isopropyl stearate. isopropyl isostearate, butyl stearate, octyl stearate, hexyl laurate, cetyl stearate, diisopropyl adipate, isodecyl oleate, diisopropyl sebacate, isostearyl lactate and lauryl lactate: fatty acids such as lauric, myristic, palmitic, stearic, oleic, linoleic. and behenic, acid: fatty alcohols such as lauryl, myristyl, cetyl, isocetyl, stearyl, isostearyl, oleyl, ricinoleyl. erucyl, and 2-octyl dodecanol, alcohols; lanolin and its derivatives such as lanolin, lanolin oh, lanolin wax, lanolin alcohols, lanolin fatty acids, isopropyl lanolate. ethoxylated lanolin, and acetylated lanolin alcohols such as ACETULAN®, a trademark and product of Amerchol Corporation, Edison, New Jersey: and hydrocarbons such as petrolatum and squalene. Any of the components such as the hquid esters and sihcone fluids, materials characterized by their refractive indices, especiahy the sihcone fluids, described above can be selected to enhance the clarity and transmission of hght as evaluated by measurements of transmittance of hght. One such device is a turbidimeter such as Model 965- 10A Digital Direct-Reading Turbidimeter from Orbeco Analytical Systems, Inc., Farmingdale. New York, with the use of acceptable accepted test protocols such as ASTM D 5180 - 93 entitled "Standard Test Method for Quantitative Test for Turbidity in Clear Liquids: ASTM D 1889 - 94 entitled "Standard Test Method for Turbidity of Water": and selected methods from Standard Methods for the Examination of Water and Wastewater (American Pubhc Health Association Washington D.C, 1995): No. 2130 "Turbidity". Values in the range of 30-950 nephelometric turbidity units (NTU), preferably below 800 NTU and more preferably below200 NTU, and particularly below 100 NTU are preferred. A desired feature of the present invention is that a clear, or transparent, cosmetic composition, (for example, a clear or transparent deodorant or antiperspirant composition) can be provided. The term clear or transparent according to the present invention is intended to connote its usual dictionary definition: thus, a clear, for example, stick or gel antiperspirant composition of the present invention ahows ready viewing of objects behind it. By contrast, a translucent composition, although allowing light to pass through, causes the hght to be scattered so that it whl be impossible to see clearly objects behind the translucent composition. An opaque composition does not ahow hght to pass therethrough. Within the context of the present invention, a gel or stick is deemed to be transparent or clear if the maximum transmittance of hght of any wavelength n the range 400-800 nm through a sample 1 cm thick is at least 35%, preterably at least 50% . The gel or stick is deemed translucent if the maximum transmittance ot such hght through the sample is between 2% and less than 35%. A gel or stick is deemed opaque it the maximum transmittance ot hght is less than 2%. The transmittance can be measured by placmg a sample ot the atorementioned thickness mto a hght beam ot a spectrophotometer whose work g range mcludes the visible spectrum, such as a Bausch & Lomb Spectromc 88 Spectrophotometer. As to this definition ot clear, see European Patent Apphcation Publication No. 2 1.334 A2. Thus, accordmg to the present mvention. there are differences between transparent (clear), translucent and opaque compositions. Particular embodiments ot the mvention which may be used are antiperspirant sticks having the following formulations which are at least translucent. Because ot the chemical instability ot DBS m the presence ot water low pH media, it is preferred that antiperspirant formulations be essentiahy anhydrous and contam sufficient buttermg agents to keep the pH m the range ot 4.0 - 5.0. Deodorants and other cosmetic preparations which are at a higher pH do not require this restriction Particular compositions accordmg to the present mvention mclude those made by combining in percent by weight based on the total weight ot the composition: (a) 6.0 - 35% of the silicone fluid phase; (b) 25-70% ot a polyhydric alcohol selected trom the group consisting ot propylene glycol. dφropylene glycol. tπpropylene glycol, tetrapropylene glycol and mixtures thereot; (c) 1.5-2.5% dibenzylidene sorbitol: and (d) 5-25% antiperspirant active. Throughout the present specification, where compositions are described as including or comprising specific components or materials, or where methods are described as including or comprising specific steps, it is contemplated by the inventors that the compositions of the present invention also consist essentiahy of, or consist of, the recited components or materials, and also consist essentiahy of, or consist of, the recited steps. Accordingly, throughout the present disclosure any described composition of the present invention can consist essentiahy of. or consist of. the recited components or materials, and any described method of the present invention can consist essentiahy of, or consist of, the recited steps. As noted above, the compositions of the present invention have less tack than conventional cosmetic sticks. This is especiahy true of antiperspirant sticks made according to the invention. Tack can be evaluated by various techniques including the Forearm Flex Test. Forearm Flex Test - In this test the administrator first over- wraps the test products to hide their identity from the panehsts and then gives each sample a code number to hide their identity from the statistician who will analyze the data. These precautions are done to avoid bias of the panehsts and the test evaluators. Next, one of two products is apphed to one arm at the crease of the elbow and the second product is apphed to the same area of the other arm. The two products are apphed in a simhar manner. Product apphcation is done by either counting the number of strokes or by weighing the products to be tested before and after. Products are apphed in random fashion to eliminate left-handed or right-handed biases. The ambient room temperature and humidity are recorded. Using the same control product for every test ahows for a comparison between test results for various experimental formulations. The panehsts evaluate the tested products for several aesthetic attributes including, but not limited to, wetness, oily/greasy feel, glide, and, most importantly, tackiness/stickiness. The panehsts evaluate initial tackiness immediately after a product apphcation and repeatedly at predetermined time intervals for an overah time of 90 minutes. The assessment of tack is made by flexing the arm and judging the adherent forces between contacted skin surfaces. A scale of 1 to 7 is used by each panelist with 1 = Not Tacky and 7 = Extremely Tacky. The collected data is used to generate a "Tack Profile" which is a plot of Tackiness versus Time. Data analysis using a statistical software package cahed JMP from SAS Institute (Cary. North Carolina) permits identification of products which are significantly different from the Control sample. The Control is selected to be a competitive benchmark currently in the marketplace which represents what is beheved to be the best commerciahy avahable standard. In addition to an analysis of product performance at spechic time periods, the performance of the tested sample throughout the 90 minute test period can be made by calculating the area under each curve in the Tack Profile graph and comparing the differences. The following Examples are given as illustrative of the invention but other modifications may be made by those skilled in the art which are within the spirit and scope of the invention. Unless otherwise noted ah amounts are in weight percents. Ah chemical symbols and scientific abbreviations have their usual and customary meanings and ah temperatures are in degrees C. The aluminum zirconium tetrachlorhydrex glycine complex hsted in the following examples is a solution comprising about 28% by weight actives in a mixture of polyhydric alcohols (such as Westchlor® ZR 35B from Westwood Chemical. Middletown. New York). In addition about 0.75% + 0.25 guanidine carbonate was added to the actives solution (although the amount may be varied from 0.5% - 1.0% guanidine carbonate). It will also be appreciated by those sk led in the art that preheating of ingredients was done as needed to ensure good mixing. EXAMPLES Example A General Method A The general method used to make the compositions described in Examples 1-5 is as follows: (a) Weigh all of the ingredients to be combined in the silicone phase and place them in a 250 ml beaker. Heat the contents to 100 degrees C. (b) Weigh the aluminum zirconium tetrachlorhydrex gly and place it in a 50 ml beaker and heat it to a temperature of 100 degrees C. (c) Weigh the propylene glycol and place it in a 250 ml beaker. (d) Heat the beaker containing propylene glycol on a hot plate until the temperature of the contents is about 100 degrees C while dissolving the cellulose in the propylene glycol. Continue heating this mixture until it is at a temperature of 130 - 135 degrees C. (e) Weigh the DBS, and add it to the mixture in Step (d) with stirring until the DBS is dissolved. (f) After the blend of propylene glycol cellulose/DBS is clear and all the DBS has been dissolved, remove the solution from the hot plate and allow it to cool to a temperature of 1 10 degrees C. (g) Add the heated aluminum zirconium tetrachlorhydrex gly from Step (b) with stirring to the solution in Step (f) and immediately add the heated sihcone mixture from Step (a) with very slow addition and with turbulent stirring to form the silicone/propylene glycol emulsion. The addition of the heated silicone mixture should be done at a slow rate. This addition should be done without continued heating to avoid degrading the DBS. (h) Pour the emulsion from Step (g) into the desired container (mold, packaging, etc.) which is at a temperature in the range of the gelling point (100 - 105 degrees C). Example B General Method B Gel Phase 1 ) Charge the formula amount of Propylene Glycol (PG) to the main mixing vessel and begin agitation sufficient enough to create a vortex. 2) Slowly sprinkle-in the Hydroxypropyl Cellulose (HPC) or Hydroxypropyl Guar (HPG) into the PG. 3) Once the HPC or HPG is homogeneously dispersed begin heating to 60 degrees C to facilitate complete hydration with continued agitation. 4) Slowly add Dibenzylidene Sorbitol (DBS) at 60 degrees C. Continue heating and mixing until 95- 105 degrees C. Mix until all of the DBS is dissolved into solution. Actives Phase 1) Add the actives to a suitable mixing vessel and heat to 95- 105 degrees C with agitation. 2) Charge to Gel Phase in the main mixing vessel once all of the DBS has been dissolved. Silicone Phase 1) Charge the Dimethiconol to a suitable side mixing vessel and begin mixing. 2) Add the Phenyl Trimethicone and begin heating to 95C-105 degrees C. 3) Add the Dimethicone Copolyol and continue heating to 95C-105 degrees C. 4) Add to the combined Gel Phase/ Actives Phase in the main mixing vessel. Fragrance/Colors 1) Once combined Gel, Actives and Shicone Phases are homogeneous begin cooling to 10 degrees C above the titer (gehation temperature). 2) Charge Fragrance/Colors with continued agitation. 3) Once Fragrance and Colors are incorporated begin filling into barrels at 5 degrees C above the titer point. Example C Alternative Order of Addition This method can be used when additional solvents partially replace propylene glycol or when the DBS level drops below 2 weight percent. Either of these occurrences lowers the dissolution temperature. Examples of such solvents with a lower DBS dissolution temperature include propylene carbonate, polyhydric alcohols (for example, dipropylene glycol. dipropylene glycol. tripropylene glycol. tetrapropylene glycol), PEG-6. carbonate, N-pyrrolidone and mixtures of such solvents. Gel Phase 1) Charge the formula amount of Propylene Glycol (PG) to the main mixing vessel and begin agitation sufficient enough to create a vortex. 2) Slowly sprinkle-in the Hydroxypropyl Cellulose (HPC) or Hydroxypropyl Guar (HPG) into the PG. 3) Once the HPC or HPG is homogeneously dispersed begin heating to 60 degrees C to facilitate complete hydration with continued agitation. 4) Slowly add Dibenzylidene Sorbitol (DBS) at 60 degrees C Continue heating and mixing until 95- 105 degrees C. Mix until all of the DBS is dissolved into solution. Silicone Phase 1 ) Charge the Dimethiconol to a suitable side mixing vessel and begin mixing. 2) Add the Phenyl Trimethicone and begin heating to 95-105 degrees C. 3) Add the Dimethicone Copolyol and continue heating to 95- 105 degrees C. 4) Add to the Gel Phase/ Actives Phase in the main mixing vessel after all of the DBS has been dissolved. Actives Phase 1) Charge the actives to a suitable mixing vessel and heat to 95-105 degrees C with agitation. 2) Add the actives phase to the combined Gel Phase/Silicone Phase in the main mixing vessel. Fragrance/Colors 1 ) Once the combined Gel, Actives and Silicone Phases are homogeneous begin cooling to 10 degrees C above the titer (gehation temperature). 2) Add Fragrance/Colors with continued agitation. 3) Once Fragrance and Colors are incoφorated begin filling into the desired package or mold at 5 degrees C above the titer point.

The amounts of the ingredients are hsted in Table 3. AU amounts are in weight percent based on the total composition as 100 percent. TABLE 3 * Example 9 used a silicone polyether with an HLB of 5 (DC Surfactant 190) and Example 10 used a polyether surfactant with an HLB of 12.2 (DC Surfactant 193). The compositions were evaluated as described in Example 8. The composition of Example 9 was judged to be stable with good structure. The formulation of Example 10 was judged to have poor stability after 24 hours and the silicone phase separated. Note that Example 10 with propylene glycol used a surfactant with an HLB value of 12.2 which is greater than 10. Example 11 The method described in Example 8 was repeated with the following amounts of ingredients: 25.8% silanol 3.0% dimethicone copolyol (and) cylcomethicone (DOW CORNING® 3225C Formulation Aid) 10.0% phenyltrimethicone (DOW CORKING® 556 Fluid) 29% propylene glycol 2.0% DBS 0.2% hydroxypropyl cellulose 30.0% Al-Zr tetrachlorhydrex gly 100% Total i Using a scale of 0- 10 where 0=opaque and 1 (^transparent, the composition was observed visually and rated as 4 for clarity. Example 12 0 The shanol and polyether surfactant described in Example 6 were used with the method described in Example A for compositions formulated with the following amounts of ingredients: 10.0% silanol 0.30% polyether surfactant 5 15.0% phenyltrimethicone (DOW CORNING® 556 Fluid) 41.7% propylene glycol 2.0% DBS 1.0% hydroxypropyl cellulose 30.0% Al-Zr tetrachlorhydrex gly 0 100% The composition was evaluated using the scale described in Example 1 1 and rated as "9" indicating a clear composition. 5 Example 13 Propylene glycol (40.4%) and hydroxypropyl ceUulose ( 1.0% KLUCEL) is charged to a main mixing vessel and heat is used to raise the temperature to about 100 degrees C. DBS (2.0%) is added and with stirring and heating until the DBS is melted into the solvent mixture (temperature is at 130- 135 degrees C). Guanidine carbonate (0.3%) is added with cooling and stirring as the temperature is lowered to about 105- 1 10 degrees C. In a separate container PPG-5-Ceteth-20 (5.0% PROCETYL AWS, from Croda) is added with stirring to the actives phase (30.0% of Al-Zr tetrachlorhydrex gly). A sihcone phase is made in a separate vessel by combining sUanol ( 10.0%* of a shanol described in Example 6), a polyether surfactant of the type as described in Example 6 (0.30%), and phenyltrimethicone ( 10.0% of DOW CORNING® 556 Fluid) with heating and stirring to about 105 degrees C. The mixture with the actives is added at 105 degrees C to the main vessel. Then the sihcone phase is added. An emulsion is made with the combination of the contents of the two vessels with stirring and cooling to about 100 degrees C. Further coohng is ahowed and when the mixture is at a temperature of about 85-90 degrees C. PEG- 150 pcntaerythrityl tetrastearate ( 1.0% CROTHIX) is added with stirring until melted. The mixture is aUowed to cool as needed to a temperature in the range of 85-90 degrees C and then may be poured into the final containers for setting. A composition made by such a process was evaluated by the scale described in Example 1 1. It was soft but the combination helped to reduce droplet size of the internal phase, thus improving clarity.
