- compositions of the invention are prepared by combining all of the ingredients in the following manner: add the glycol to the vessel, followed by adding fumed silica, and then agitate until the materials are completely dispersed. Then add DBS and agitate until the materials are dispersed (Phase 1) . Heat to about 128 degrees C until the DBS is completely dissolved. In a separate vessel combine antiperspirant active, fragrance and silicone fluid (like phenyl trimethicone) . (This is Phase 2) . With agitation slowly add Phase 1 to Phase 2. Fill the resulting batch into canisters at about 85°C to about 90°C and cool rapidly to room temperature (about 68°-72°F) .
- compositions of the invention are prepared as follows:
- phase 1 DBS , fumed silica and propylene glycol were combined in a suitable tank and heated to about 128 degrees C with moderate agitation in a steam-jacketed tank (phase 1) .
- Phase 2 Substituted dimethicone Dow Corning 556 fluid) Westchlor AZ28106 in a diluent such as propylene glycol and a fragrance were combined (phase 2)
- Phase 1 was added slowly to phase 2 with moderate agitation and the batch was cooled to about 70 to about 75 degrees C or just above the set point of the gellant .
- the batch was filled into canisters at 70C and cooled rapidly to entrap dispersed phase rapidly. This cooling was at about 5 degrees C per minute to prevent layering of the dispersed phase.
- mixture from step 4 was measured with a Perkin Elmer UV Spectrophotometer spectrometer to determine that it had at least 30% transmission at a wavelength of 500 nanometers with a one centimeter path length.
- compositions of the invention contain large amounts of polyhydric alcohols, like glycol.
- the dimethicones, substituted dimethicones substituted polysiloxanes or mixtures thereof which are employed in the compositions of the invention have the unusual property of being neither soluble nor insoluble in the polyhydric alcohols, but rather form uniform dispersions of microscopic droplets in the polyhydric alcohols.
- the uniform dispersion of dimethicone bubbles is believed to act as a detackifier, because the dispersion of bubbles is uniform and because the bubbles have a certain range of particle sizes, and further because there are certain average distances between the bubbles.
- This uniform dispersion of dimethicones, substituted dimethicones, substituted polysiloxanes or mixtures thereof contacts the skin and is believed to counteract the stickiness of the antiperspirant actives and the polyhydric alcohol (s) in the compositions. Thus, the composition is less sticky to the user.
- Phase 1 was slowly added to Phase 2.
- the mixture was added to a deodorant canister. Then the mixture in the canister was rapidly cooled to room temperature about 20°C to about 25°C at a rate of 5°C per minute.
- compositions of the invention may be prepared in a similar manner.
