WO 2005/044213 PCT/US2004/035917 Underarm Products With Superabsorbent Component Field of the Invention This invention relates to suspension products that are useful to reduce underarm 5 wetness, for example, antiperspirant and/or deodorant agents. These products are particularly advantageous in providing deodorants that have reduced wetness without the use of an antiperspirant active. They are also advantageous in providing antiperspirants with additional wetness benefits. This application is a continuation-in part of copending case U.S. Serial Number 10/696,764, filed October 29, 2003. 10 Background of the Invention A variety of technologies have attempted to use superabsorbent polymers of various types in a wide variety of applications. These technologies include the construction of diaper products for children and adults, and the use of superabsorbent polymers to clean up liquid spills. The problems associated with the use of such 15 polymers in personal care applications include a wet and sticky feel and skin irritation. Additionally, it has been difficult to find a way of applying such products in the underarm area in a way that results in an aesthetically acceptable product form. It has now been found that selected superabsorbent polymers in certain formulations both with and without antiperspirant or deodorant agents may be used to 20 create superior anti-wetness products. Because of the characteristic that they have some salt tolerant behavior, these polymers can also be used in the presence of antiperspirants to create superior wetness control. Brief Summary of the Invention The invention comprises an underarm product suitable for use to reduce wetness 25 under the arm. It may be viewed as providing some deodorancy effect. Additionally, an antiperspirant active may be included to provide an antiperspirant/deodorant. This underarm product is a suspension product which may be a stick or soft solid and which comprises a superabsorbent polymer which is a surface modified sodium polyacrylate salt and which has a critical level of salt tolerance. The surface modification allows for 30 greater water absorption in the presence of salt, i.e. ionic strength. While these homopolymers may be used in a variety of particle sizes, it is generally believed that the smaller sizes are preferred (for example, less than 100 microns, such as particle size of 20-30 microns, or, for certain types of superabsorbents, particle sizes of 200-300 microns can be tolerated). 35 WO 2005/044213 PCT/US2004/035917 The formulations of the invention may be made as antiperspirants and/or deodorants. In the case of antiperspirants, the products give an extra measure of protection against wetness. In the case of deodorants, the products may be made with low levels of antiperspirant active or with other agents which provide a deodorizing 5 effect but which are not antiperspirant salts. Detailed Description of the Invention Products formulated according to the invention comprise suspension products which are sticks or soft solids comprising: 10 (a) 0.01-20 weight % (particularly 1-20%, especially 0.1-10 % and, more particularly, 0.5-5%) of a polyacrylate superabsorbent polymer (sodium salt), with a salt or ionic strength tolerance under the Baseline Absorption Test described below sufficient to give at least 25 weight % water absorption (for example, materials having a mean particle size less than 100 microns); 15 (b) 10-88 weight % of a volatile silicone having a flash point of 100 degrees C or less (particularly a D4-D6 cyclomethicone; and especially a D5 or D6 cyclomethicone or a combination of D5 and D6 cyclomethicones); (c) a gelling agent selected from the group consisting of 5-30 weight % stearyl alcohol; 0.1-20 weight % waxes (for example, Japan wax, hydrogenated castor oil); 0.1 20 10 weight % (on an actives basis) silicone elastomer; 0.1-3 weight % siliconized polyamides; 0.1-20 weight % low molecular weight polyethylene having a molecular weight in the range of 400-1000 (for example 400 such as Performalene-400 from Baker Petrolite, Polymer Division, Sugar Land, Texas) and combinations of the foregoing; 25 (d) 0-5 weight % of a surfactant with a hydrophilic/lipophilic balance ("HLB value") in the range of 3-13 (for example, from 0.05-50 weight % (particularly 1-30%) of a silicone copolyol which is 10% in cyclomethicone, or its equivalent may be used for a soft solid); (e) an antiperspirant or a deodorant ingredient such as 0-25 weight % (for 30 example, 0.1-5 weight % if the antiperspirant a active i s used for d eodorancy and not wetness control, 8-25 % of an antiperspirant active if more wetness control is desired) or an effective amount of a deodorizing agent which is not an antiperspirant active; -2- WO 2005/044213 PCT/US2004/035917 (f) 0-20 weight % (particularly 5-10 %) of a nonvolatile silicone having a flash point greater than 100 degrees C; and (g) 0-20 weight % (particularly 2-12 %) of an emollient (for example, a member selected from the group consisting of C12-15 alkyl benzoate, PPG-3-myristyl ether, and 5 hydrogenated polyisobutene (Polyisobutene 250)); provided that: the water content is < 2 weight % (as based on added water and excluding any waters of hydration such as with the antiperspirant salt) and the ratio of superabsorber to active salt is in the range of 0.13-4 : 1, particularly in the range of 0.18-3 : 1. 10 While no water is recited as being added, up to 2 weight % water may be present because of the types of raw materials used. With regard to the amount of volatile silicone used in the invention, 10-88 weight % is used for stick products and soft solids, with the degree of hardness being controlled by the use of gelling agents. 15 Optionally, one or more other ingredients can be used such as fragrance, coloring agents, antibacterial agents, masking agents, additional surfactants (such as PEG-8 distearate) or fillers (for example, tale). The stearyl alcohol used in this invention is preferably a straight chain material with no unsaturation. 20 Examples of superabsorber materials that work in this invention include HySorbTM 8100 and HySorbim CL-15 (from BASF, North Carolina), preferably ground to particle size not exceeding 100 microns; AQUAKEEP J-550 and AQUAKEEP 1 OSH-N (from Kobo Products, Inc., South Plainfield, NJ) also ground to a particle size in the range of less than or equal to 100 microns. (Note that J-550 has mean particle 25 size of 200-300 microns, and 10SH-N has a mean particle size of 20-30 microns.) A reduced particle size for the various types of superabsorbents described is desired to reduce/eliminate gritty feel in the product. For example, the HySorb TM products are preferred to have a particle size not exceeding 100 microns because of reducing gritty feel and larger particles will not form a satisfactory product in 30 processing (for example, settling issues). A particular range of particle sizes includes superabsorbents having at least 80-85 weight % of the particles with a size < 75 microns, and another particular range is from 6-65 microns with no more than 10% of -3- WO 2005/044213 PCT/US2004/035917 the particles having a size less than 6 microns. For many of these products, grinding of stock material is needed to achieve the desired particle sizes. While the invention has been described in terms of selected superabsorbers and actives, especially in a selected ratio, it is to be noted that modifications in type and 5 amount of superabsorber may be made to ensure that the water absorbency requirements are met. Thus, in the Tables below, it will be described how to balance these two ingredients to achieve the effect. Volatile silicones and silicone surfactants are also used in the invention. By volatile silicone material is meant a material that has a flash point of 100 degrees C or 10 less at atmospheric pressure. Such volatile silicones include conventional cyclic and linear volatile silicones such as cyclomethicone (especially cyclopentasiloxane, also called "D5"), "hexamethyldisiloxane", and low viscosity dimethicone (for example, Dow Coming® 200 fluid having a viscosity of 0.5-5 centistokes). Illustratively, and not by way of limitation, the volatile silicones are one or more members selected from the 15 group consisting of cyclic polydimethylsiloxanes such as those represented by Formula I:

Particular examples of suitable dimethicone copolyols are available either commercially or experimentally from a variety of suppliers including Dow Corning 10 Corporation, Midland, MI; General Electric Company, Waterford, NY; Witco Corp., Greenwich, CT; and Goldschmidt Chemical Corporation, Hopewell, VA. Examples of specific products include DOW CORNING@ 5225C from Dow Coming which is a 10% dimethicone copolyol in cyclomethicone; DOW CORNING@ 2-5185C which is a 45-49% dimethicone copolyol in cyclomethicone; SILWET L-7622 from Witco; ABIL 15 EM97 from Goldschmidt which is a 85% dimethicone copolyol in D5 cyclomethicone; and various dimethicone copolyols available either commercially or in the literature. It should also be noted that various concentrations of the dimethicone copolyols in cyclomethicone can be used. While a concentration of 10% in cyclomethicone is frequently seen commercially, other concentrations can be made by stripping off the 20 cyclomethicone or adding additional cyclomethicone. The higher concentration materials such as DOW CORNING@ 2-5185 material is of particular interest. In one particular embodiment 0.5-50 weight % (particularly 10-30 %) of a 10% silicone copolyol such as dimethicone copolyol in cyclomethicone mixture may be used, wherein the amount of mixture added is selected so that the level of silicone 25 copolyol in the cosmetic composition is in the range of 0.05-5.0% (particularly 0.1 3.0%). The antiperspirant actives that can be utilized according to the present invention are conventional aluminum and aluminum/zirconium salts, as well as aluminum/zirconium salts complexed with a neutral amino acid such as glycine ("gly"), 30 as known in the art. See each of European Patent Application Number 512,770 Al and PCT case WO 92/19221, the contents of each of which are incorporated herein by reference in their entirety, for disclosure of antiperspirant active materials. The -9- WO 2005/044213 PCT/US2004/035917 antiperspirant active materials disclosed therein, including the acidic antiperspirant materials, can be incorporated in the compositions of the present invention. Suitable materials include (but are not limited to) aluminum chlorohydroxide, aluminum chloride, aluminum sesquichlorohydroxide, zirconyl hydroxychloride, and aluminum 5 chlorohydrol-propylene glycol complex. These include, by way of example (and not of a limiting nature), aluminum chlorohydrate, aluminum chloride, aluminum sesquichlorohydrate, zirconyl hydroxychloride, aluminum-zirconium glycine complex (for example, aluminum zirconium trichlorohydrex gly, aluminum zirconium pentachlorohydrex gly, aluminum zirconium tetrachlorohydrex gly and aluminum 10 zirconium octochlorohydrex gly), and mixtures of any of the foregoing. The aluminum containing materials can be commonly referred to as antiperspirant active aluminum salts. Generally, the foregoing metal antiperspirant active materials are antiperspirant active metal salts. In the embodiments which are antiperspirant compositions according to the present invention, such compositions need not include aluminum-containing 15 metal salts, and can include other antiperspirant active materials, including other antiperspirant active metal salts. Generally, Category I active antiperspirant ingredients listed in the Food and Drug Administration's Monograph on antiperspirant drugs for over-the-counter human use can be used. In addition, any new drug, not listed in the Monograph, such as tin or titanium analogues of the aluminum salts listed above, 20 aluminum nitratohydrate and its combination with zirconyl hydroxychlorides and nitrates, or aluminum-stannous chlorohydrates, can be incorporated as an antiperspirant active ingredient in antiperspirant compositions according to the present invention. Preferred antiperspirant actives that can be incorporated in the compositions of the present invention include the enhanced efficacy aluminum salts and the enhanced 25 efficacy zirconium/aluminum salt-glycine materials, having enhanced efficacy due to improved molecular distribution, known in the art and discussed, for example, in PCT No. W092/19221, the contents of which are incorporated by reference in their entirety herein. Antiperspirant actives can be incorporated into compositions according to the 30 present invention in amounts in the range of 0 - 10% (on an anhydrous solids basis), preferably 5 - 10%, by weight, of the total weight of the composition. The amount used will depend on the formulation of the composition. For example, at amounts in the -10- WO 2005/044213 PCT/US2004/035917 lower end of the broader range (for example, 0.1 - 5%), the antiperspirant active material will not substantially reduce the flow of perspiration, but will reduce malodor, for example, by acting as a deodorant material, for example, by acting as an antimicrobial or complexing with the malodorous components of human perspiration. 5 Deodorant active materials can include lesser amounts of antiperspirant actives, such as in the range of 0.1-5%, as well as fragrances, and effective amounts of antimicrobial agents, for example, farnesol, bacteriostatic quaternary ammonium compounds (such as cetyl trimethyl-ammonium bromide, and cetyl pyridinium chloride), 2, 4, 4'-trichloro-2'-hydroxydiphenylether (Triclosan), N-(4-chlorophenyl) 10 N'-(3,4-dichlorophenyl)urea (Triclocarban), silver halides, octoxyglycerin (SENSIVATM SC 50) and various zinc salts (for example, zinc ricinoleate) may also be included in formulations of the present invention. The bacteriostat can, illustratively, be included in the composition in an amount of 0.0 1-5.0% by weight, of the total weight of the composition. Triclosan or Triclocarban can, illustratively, be included in 15 an amount of from 0.05% to about 5.0% by weight, of the total weight of the composition. Non-volatile silicones may also be used in the formulations of this invention. Such nonvolatile silicones have a flash point greater than 100 degrees C and a viscosity in the range of 6-1000 centistokes. Suitable non volatile silicones include linear 20 organo-substituted polysiloxanes which are polymers of silicon/oxygen with a general structure: (1) (R") 3 SiO(Si (R") 2 O)xSi(R 12

A second 5 composition is made as a control except that no superabsorbent ("SA") is used. Samples (2 grams in the form of shavings of the stick product) of each of these compositions are weighed into separate 16 x 100 mm Kimax disposable culture tubes. Water (2.0 g) is added to each of the tubes. The tubes are centrifuged for 5 minutes at 3000 rpm whereby the water, if not completely absorbed, settles at the bottom of the tube. The % 10 water absorption is calculated as: (height of the water in control - height of water in tube with SA) X 100 height of water in control In performing the Baseline Absorption Test for the standard of this invention, the ratio of water : superabsorber is set as 20:1 by weight amounts. (Note that data is included 15 below for 10:1 and 30:1 ratios, but the standard test to be used is using a 20:1 ratio). The Baseline Absorption Test is important because not all superabsorbents will work in this invention. The compositions of this invention have a brutal environment from the standpoint of salt content, especially for antiperspirant products which contain about 15-22 weight % of an active salt such as an aluminum zirconium 20 tetrachlorohydrex glycine material. In order to select an appropriate superabsorber which can maintain sufficient capacity in a high salt environment, it has been found that the Baseline Absorption Test is the best predictor of which superabsorbers will work. Other parameters such as particle size do not appear to show any consistent trends. The compositions of this invention include sticks and soft solids. The 25 compositions of the invention may range in clarity from opaque to white. For deodorant stick products, the following general amounts of ingredients may be used: Formulation A (a) 5-25 weight % (particularly 8-20%) superabsorbent polymer as described above; 30 (b) 10-25 weight % of a gellant (for example, selected from the group consisting of silicone elastomer of the type described above (for example, KSG-15 from Shin-Etsu or DC 9040 from Dow Coming), stearyl alcohol, waxes (both low and/or high melting -15- WO 2005/044213 PCT/US2004/035917 point waxes), hydrogenated castor oil, and low molecular weight polyethylene (such as a molecular weight of about 400 for example, Performalene-400); (c) 40-70 weight % of a volatile silicone selected from the group consisting of a cyclomethicone (for example, one or more of D4, D5 or D6); 5 (d) 0-15 weight % of a non-volatile silicone which is a dimethicone having a viscosity in the range of 6-1000 centistokes; (e) 2-10 weight % of an emollient selected from the group consisting of polyisobutene, and C12-15 alkyl benzoates (such as FINSOLV TN); (f) 0-5 weight % (especially 1-3%) fragrance; 10 (g) 0-10 weight % (particularly 1-5%) surfactants (for example, PEG-8 distearate or PPG-3 myristyl ether); (h) 0-5% antiperspirant active; and (i) less than 2 weight % water. For soft solid deodorant products, the following general amounts of ingredients 15 may be used: Formulation B (a) 70-99.94 weight % silicone elastomer of the type described above (for example, KSG-15 or DC 9040); (b) 0.01-30 weight % superabsorbent of the type described above; 20 (c) 0-5% antiperspirant active; (d) 0-5 weight % fragrance; and (e) less than 2 weight % water. For antiperspirant stick products containing superabsorber, the following general amounts of ingredients may be used: 25 Formulation C (a) 1-10 weight % (particularly 2-8%) superabsorbent polymer as described above; (b) 10-25 weight % of a gellant (for example, selected from the group consisting of silicone elastomer of the type described above (for example, KSG- 15 from Shin-Etsu or DC 9040 from Dow Corning), stearyl alcohol, waxes (both low and/or high melting 30 point waxes), hydrogenated castor oil, and low molecular weight polyethylene (such as a molecular weight of about 400 for example, Performalene-400); -16- WO 2005/044213 PCT/US2004/035917 (c) 40-70 weight % of a volatile silicone selected from the group consisting of a cyclomethicone (for example, one or more of D4, D5 or D6); (d) 0-15 weight % of a non-volatile silicone which is a dimethicone having a viscosity in the range of 6-1000 centistokes; 5 (e) 2-15 weight % of an emollient selected from the group consisting of polyisobutene, and C12-15 alkyl benzoates (such as FINSOLV TN); (f) 0-5 weight % (especially 1-3%) fragrance; (g) 0-10 weight % (particularly 1-5%) surfactants (for example, PEG-8 distearate or PPG-3 myristyl ether); 10 (h) 10-25% antiperspirant active; and (i) less than 2 weight % water. For soft solid antiperspirant products containing superabsorber, the following general amounts of ingredients may be used: Formulation D 15 (a) 50-80 weight % silicone elastomer of the type described above (for example, KSG 15 or DC 9040); (b) 0.01-10 weight % superabsorbent of the type described above; (c) 10-25% antiperspirant active; (d) 0-5 weight % fragrance; and 20 (e) less than 2 weight % water.

The dimethicone (DC 200, 10 censtistokes from Dow Coming Corporation, 5 Midland, MI) and C12-15 alkyl benzoate (FINSOLV TN, from Finetex Elmwood Park, NJ) (and polyisobutene and PPG-3 myristyl ether for Example 3) are added to a suitable size first beaker and heated with stirring to 55-60 degrees C. The Japan wax substitute 525 (if used) is added and mixed until melted. The temperature is increased to 82-85 degrees C and the low molecular weight polyethylene (Performalene-400 from Baker 10 Petrolite) is added and mixed until melted. The mixture is then cooled to a temperature of about 80 degrees C. In a separate second beaker the silicone elastomer (KSG-15 from Shin-Etsu Silicones of America, Akron OH) is added followed by the addition of the cyclomethicone (Cyclomethicone 345 from Dow Corning Corporation, Midland, MI). The mixture is stirred for about 5 minutes and then heated to a temperature of 15 about 70 degrees C. The silicone elastomer/cyclomethicone mixture from the second beaker is then added to the first beaker with continuous stirring while maintaining the temperature at 78-80 degrees C. The superabsorbent material (HySorbTM 8100, BASF, North Carolina), ground to particle size less than 100 microns, and the antiperspirant active (active as described in Example 3), if used, are then added at this temperature 20 and stirred for 10 minutes. The fragrance is added at the same 78-80 degrees C temperature and stirred for 1 minute. The product is poured into suitable containers (size is approximately 3 cm (width at widest part of oval) X 6 cm (length of base) X 10 cm (height) with an ovoid shape) at 78-80 degrees C and cooled for 15 minutes in a refrigerator at about 4 degrees C and then at room temperature. 25 Example 2 - Deodorant Stick Product A stick product of about 400 grams may be made using the ingredients listed in Table A.

The cyclomethicone and C12-15 alkyl benzoate are added to a suitable size beaker and heated to a temperature of about 70 degrees C. Stearyl alcohol is added with stirring at 70 degrees C until it is melted. PEG-8 distearate is added with mixing 15 while maintaining the temperature at 70 degrees C until it is dissolved. The temperature of the mixture is then increased to about 80 degrees C. Hydrogenated castor oil is added with mixing at 80 degrees C until it is completely dissolved.

This was shown through the following experiment. Samples (2.0 g) of the formulations from each of Examples 1-4 were weighed into 16 x 100 mm Kimax disposable culture tubes and 1.0 and 2.0 g of water were added to the formulations. 10 The tubes were centrifuged for 5 minutes at 3000 rpm whereby the water, if not absorbed, settled at the bottom of the tubes. Examples 1-4 showed no residual water, indicating that all the water was absorbed in these formulations. Thus, when the antiperspirant active salt is low, water absorption by the superabsorbent is high. Water Absorption of Antiperspirants Containing Different Superabsorbents 15 The water absorption capacity of superabsorbent polymers are known to be affected by salts, such as sodium chloride or an antiperspirant active. Examples 6 and 8 (TABLE C) show two fonnulations, one containing a superabsorbent which is more salt tolerant (HySorbTM 8100, from BASF, Charlotte, NC) and the other containing a starch graft copolymer of poly (2-propenamide-co-2-propenoic acid, sodium salt) ("SGC") 20 and is not as salt tolerant. SGC stands for "starch graft copolymer". 25 -20- WO 2005/044213 PCT/US2004/035917 TABLE C Ingredients (weight %) Ex.6 Ex.8 Ex.9 Superabsorbent polymer (HySorb 8100; 5.00 particle size less than 100 microns) SGC 5.00 C12-15 alkyl benzoate 12.00 12.00 12.00 Cyclomethicone 345 35.80 35.80 36.80 Stearyl alcohol 16.00 16.00 20.00 Hydrogenated castor oil 4.00 4.00 4.00 PEG-8 distearate 4.00 4.00 4.00 Antiperspirant active (Summit Z576) 22.00 22.00 22.00 Fragrance 1.20 1.20 1.20 Total 100 100 100 Examples 6 and 8 were compared for their water absorption water capacity versus Example 9 (no superabsorber) as control. Samples (2.0 g) of the formulations as 5 shavings were weighed into 16 x 100 mm Kimax disposable culture tubes. Water in three different amounts (1.0, 2.0 and 3.0 g) were added to the formulations. This corresponds to water/superabsorber ratios of 10:1, 20:1 and 30: 1, respectively. The tubes were centrifuged for 5 minutes at 3000 rpm whereby the water, if not absorbed, settled at the bottom of the tubes. The height of the water was measured (in mm) and 10 the results are tabulated in Table D. TABLE D Sample Water Ratio of Height of water in tube after % Water added (g) water: centrifugation (mm) absorption superabsorber Ex 9 1.00 - 6.0 Ex 8 1.00 10 5.0 16.6 Ex 6 1.00 10 0 100 Ex 9 2.00 - 12.1 Ex 8 2.00 20 10.1 16.5 Ex 6 2.00 20 4.0 67 Ex 9 3.00 - 18.0 Ex 8 3.00 30 15.0 16.7 Ex6 3.00 30 8.5 53 -21- WO 2005/044213 PCT/US2004/035917 The results clearly demonstrate that HySorbT m 8100 superabsorbent is significantly more effective in absorbing water in the presence of a ZAG than the SGC material. At a water/superabsorber ratio of 10:1, 100% water is absorbed from the formulation containing HySorb Tm 8100 superabsorbent as opposed to only about 16.6 % for the 5 formulation containing the SGC material. At 20:1 water superabsorber ratio, about 67% of water is absorbed for the formula containing HySorbTM 8100 superabsorbent compared to 16.5% for the formulation containing SGC material. At 30:1 ratio, 53 % of water is absorbed for the formulation containing HySorbT" 8100 superabsorbent compared to 16.7% for the formulation containing SGC material. Thus, at all three 10 water/superabsorber ratios, the formulation containing HySorb TM 8100 superabsorbent performed more efficiently in absorbing water than the formulation containing SGC material. Taken together, the data indicate that the HySorbTm 8100 product absorbs water more effectively especially at high salt concentration, the concentration needed to claim antiperspirant efficacy. Therefore, it can be used in an antiperspirant product to 15 boost the efficacy of the ZAG at levels up to 25 weight %. Examples 6-9 and 10-12 Comparison of water absorbency for different superabsorbers (all of which are polyacrylates) was done on the following polyacrylate, sodium salt samples as listed in TABLE F: (a) material with a mean particle size of 20-50 microns and a bulk density 20 of 0.65 g/ml (SANFRESH ST-500 MPSA (obtained from Sanyo Chemical Industries, Japan)); (b) material with a mean particle size of 200-300 microns and a bulk density of 0.34-046 g/ml (AQUA KEEP J-550) and material with a mean particle size of 20-30 microns and a bulk density of 0.84-0.96 g/ml (AQUA KEEP 1OSH-NF) (both obtained from Kobo Products, Inc., South Plainfield, NJ). The basic formula was made by 25 combining the ingredients as listed above or as listed in TABLE E using the technique described for Examples 5-7. For the evaluation, 2 grams of water were added to 2 grams of each of the formulas and the procedure described above for Examples 6, 8 and 9 was followed. The ratio of water:superabsorber = 20:1.
