Abstract: A process is provided for the rapid wetting and dispersing of powders suitable for obtaining an essentially gas-free paste, particularly in the manufacture of toothpaste compositions. The process consists of charging a vacuum mixer with the appropriate liquids, and subjecting the liquids to a continuous vacuum that will draw the powders in at the bottom of the mixer in an area of high turbulence generated by a high speed mixing device. The turbulence caused by the expanding air entrained in the powder as it enters the vacuum and generated by the impeller of a high speed mixer, wets the powders very rapidly, inhibits the formation of undesirable lumps, and essentially minimizes loss of powders to the vacuum system. In addition, little or no air is entrained in the resulting paste.

Abstract: A formulation and method for a pump spray or roll-on antiperspirant is disclosed which antiperspirant is characterized by having superior drying properties while substantially eliminating clogging of the valve or roll-ball. The formulation comprises one or more alcohol soluble aluminum chlorhydroxide compounds in combination with an alcohol vehicle and selected silicone liquids.
