Definitions
- This invention relates to suspension products that are useful to reduce underarm 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.
- 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 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 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.
- the invention comprises an underarm product suitable for use to reduce wetness under the arm. It may be viewed as providing some deodorancy effect.
- 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 greater water absorption in the presence of salt, i.e. ionic strength. While these homopolymers maybe 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).
- the formulations of the invention may be made as antiperspirants and/or deodorants.
- antiperspirants the products give an extra measure of protection against wetness, hi the case of deodorants, the products may be made with low levels of antiperspirant active or with other agents which provide a deodorizing effect but which are not antiperspirant salts.
- Products formulated according to the invention comprise suspension products which are sticks or soft solids comprising: (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); (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- 10 weight % (on an
- HySorbTM 8100 and HySorbTM CL-15 (from BASF, North Carolina), preferably ground to particle size not exceeding 100 microns; AQUAKEEP J-550 and AQUAKEEP 10SH-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 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.
- the HySorbTM 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 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 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 amount of superabsorber may be made to ensure that the water absorbency requirements are met.

- Example 1-4 Water Absorption of Deodorants, Examples 1-4
- formulations containing zero or low levels of antiperspirant salts, i.e. at low ionic strength, (Examples 1-4) high water absorption capacity of the formulations were observed. 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. 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.
- 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 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 the results are tabulated in Table D. TABLE D
- HySorbTM 8100 superabsorbent is significantly more effective in absorbing water in the presence of a ZAG than the SGC material.
- a water/superabsorber ratio of 10:1 100% water is absorbed from the formulation containing HySorbTM 8100 superabsorbent as opposed to only about 16.6 % for the formulation containing the SGC material.
- 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.
- 53 % of water is absorbed for the formulation containing HySorbTM 8100 superabsorbent compared to 16.7% for the formulation containing SGC material.
- the formulation containing HySorbTM 8100 superabsorbent performed more efficiently in absorbing water than the formulation containing SGC material.
- 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 boost the efficacy of the ZAG at levels up to 25 weight %.
- Examples 1B-13B Examples 1B-6B can be made with the method described below using the ingredient listed in TABLE G, except that another fragrance component such as a fragrance oil encapsulated with com starch (for example, off the shelf products, customized products and/or proprietary products, for example, material obtained from Noville, Southhackensack, NJ) is also used and added such as adding this additional fragrance component after the addition of the fragrance oil at a temperature in the range of 60-63 C.
- com starch for example, off the shelf products, customized products and/or proprietary products, for example, material obtained from Noville, South hackensack, NJ
- Data for water absorbency with the Baseline Absorbency Test is listed in Table H.
- An alternative procedure "A" can also be used:
- Examples IC and 7B-9B can be made with the method described above for Examples 1B-6B, using the ingredients listed in TABLE I. Data for water absorbency with the Baseline Absorbency Test is listed in Table J. TABLE I
- Example 2B could be modified to achieve the 25% required water abso ⁇ tion by lowering the antiperspirant active to 15% and/or raising the superabsorbent to 5%.
- Example 5B could be modified to achieve the 25% required water abso ⁇ tion by lowering the amount of antiperspirant active to 15 % and/or increasing the amount of superabsorbent to 5%.
- Examples ID and 11B-13B Examples ID, 11B-13B can be made with the method described above for Examples 1B-9B, using the ingredients listed in TABLE K except that talc can be added, for example, at a temperature of 72 degrees C before the addition of the Al/Zr salt. The behenyl alcohol is added after the stearyl alcohol is added, again, for example, at a temperature of 72 degrees C.
- Mineral oil such as white mineral oil can be added with the C12-15 alkyl benzoate and heated to a temperature in the range of 82-85 degrees C. Data for water absorbency with the Baseline Absorbency Test is listed in Table L. T
- Example 1 IB and Example 12B could be altered to obtain a minimum 25 weight % water abso ⁇ tion value by raising the amount of superabsorber to 5 weight % and/or lowering the amount of antiperspirant salt to 10 weight %.
