  • Patent number: 5925338
    Abstract: The present invention is directed to a clear antiperspirant or deodorant gel composition which exhibits reduced staining while retaining excellent aethetic attributes and efficacy. The gel composition is a water-in-oil emulsion having a viscosity of about 50,000 to 250,000 cP, preferably about 100,000 to 200,000 cP. The water phase comprises about 75 to 90% of the composition and contains a deodorant or antiperspirant effective amount (e.g. about 3 to 25%) of an antiperspirant active dissolved therein. The oil phase comprises about 10 to 25% of the composition and contains a silicone oil and a polyether substituted silicone emulsifying agent. The silicone oil comprises a mixture of a non-volatile silicone, preferably a non-volatile linear silicone, and a volatile linear silicone. It has been found that reducing the amount of non-volatile silicone in the known gel composition to a relatively low level (e.g. below about 5%) and adding an amount of volatile linear silicone to the composition (e.g.

  • Patent number: 5863525
    Abstract: A clear gel-type cosmetic product has a viscosity of at least about 50,000 cps at 21.degree. C., and includes an emulsion with an oil phase and a water phase that includes an incorporated active ingredient. The refractive indices of the water and oil phases match to at least 0.0004, the refractive index of the product is about 1.4000, and the product clarity is better than thirty NTU.

  • Patent number: 5417964
    Abstract: The present invention provides a process for making a solid antiperspirant stick comprising a particulate aluminum antiperspirant salt suspended in an anhydrous carrier vehicle, wherein said carrier vehicle comprises a high melting component which melts at 70.degree. C. or higher. This process includes heating the carrier vehicle in a closed mixing vessel to a temperature in excess of 70.degree. C. preferably in excess of 75.degree. C., to melt the high melting component, adding the antiperspirant salt to the carrier vehicle, and cooling the carrier vehicle to form a solid antiperspirant stick. The improvement of the present invention comprises cooling the carrier vehicle below 70.degree. C., preferably to about 65.degree. C. or less, but above the solidification point prior to adding the antiperspirant salt and maintaining the carrier vehicle below 70.degree. C., preferably at about 65.degree. C.
