Abstract: A stable, chromatic water-in-silicone emulsion comprising: i) an aqueous phase containing a water-soluble polyol, a water-soluble polymer thickener, and water; and ii) a silicone phase containing an aromatic silicone, a silicone emulsifier and a silicone fluid carrier.

Abstract: There is provided a clear antiperspirant/deodorant gel composition. The composition is a water-in-oil emulsion having a viscosity about 7,000 cps to about 25,000 cps and a clarity from about 30 NTU or less. The composition further has an antiperspirant active, water, silicone gelling agent, and one or more silicone oils.

Abstract: The present invention process involves the exposure of antiperspirant salt solutions to ultraviolet light to cause lightening in color. The ultraviolet light can be in the wavelength range of 180 to 400 nanometers, with the longer wavelengths preferred and at an exposure time of 1 to 120 minutes. The color of the antiperspirant solutions treated with ultraviolet light approaches the color of water, commonly known in the cosmetic industry as water white. These exceptionally low color antiperspirant salt solutions are useful in development of clear and colorless antiperspirant gels, roll-ons and stick formulations.

Abstract: A method of producing activated metal salts useful in antiperspirant compositions is disclosed. The method produces the salt through an acid base reaction wherein an acid is reacted with a metal in basic form. Preferred metals include aluminum and zirconium. Activate aluminum-zirconium hydrohalide and activated aluminum-zirconium-amino acid salts can also be produced by the method of this invention.

Abstract: The present invention is directed to a method of preparing sodium aluminum lactate by reacting aluminum lactate with sodium hydroxide is an aqueous medium. The reaction is carried out within the temperature range of about 20.degree. C. to about 80.degree. C. The weight ratio of aluminum lactate to sodium hydroxide is about 5.0:1 to about 8.0:1. The weight ratio of water to sodium hydroxide is about 0.8:1 to about 2.3:1.

Abstract: This invention pertains to a process for preparing concentrated aluminum-zirconium-glycine solutions by forming a zirconium chloride complex, adding glycine to the complex and forming coordinate bonds between the zirconium chloride complex and the glycine and blending the resulting mixture with an aqueous aluminum chlorohydrate solution. Solutions which contain 45-50% solids can be produced. The solutions have shown to be stable at room temperature for greater than 3 months.

Abstract: A composition which is a colorant material having polymerized on its surface at least one methacrylate monomer. A coating of from about 0.25-2.0 percent by weight based on the weight of the colorant material provides for the improved dispersibility of the coated colorant in various fluids, an improvement in the protection of the color additive from the effects of moisture, and improved anticaking properties.

Abstract: A method of treating skin disorders such as acne by applying topically to the infected area a mixture of an antimicrobial agent and a volatile low viscosity organosilicon compound. The mixture is entrapped within and dispersed uniformly throughout discrete particles of a hydrophobic macroporous highly crosslinked polymer. The particles are spread on the skin releasing the mixture while allowing the volatile low viscosity organosilicon compound to evaporate. Excess skin oil such as sebum is simultaneously adsorbed from the skin and into the macroporous polymer.

Abstract: A precipitation polymerization process for the production of a macroporous cross-linked copolymer in which there is added to a reactor equipped with a stirrer, at least one monounsaturated monomer and at least one polyunsaturated monomer, dissolving an inorganic polymerization reaction initiator in a homogeneous minimum-boiling binary azeotrope including a solvent and water, and conducting the polymerization in the azeotrope.

Abstract: A precipitation polymerization process for producing a macroporous cross-linked copolymeric lattice, capable of adsorbing hydrophilic and lipophilic fluids, in which process there is copolymerized at least one monounsaturated monomer and at least one polyunsaturated monomer in the presence of an organic liquid which is a solvent for the monomers but not for the copolymer, initiating the copolymerization of the monomers by means of a free radical generating catalytic compound, precipitating a copolymer in the solvent in the form of a powder, and forming a dry powder by removing the solvent from the precipitated copolymeric powder. One monomer is a hydrophilic compound and the other monomer is a lipophilic compound.
