Abstract: A method of preparing esters and water soluble soaps using intensive mixing. The esters are prepared by reacting fats & oils with methanol containing caustic as a catalyst wherein the glycerin formed is removed. The resulting esters are saponified with caustic along with an additional amount of methanol to form the soap.

Abstract: A protective package system for containing a delivery cartridge for volatile substances such as fragrances, deodorizers, air fresheners and the like, wherein the cartridge includes an active ingredient reservoir with a permeable surface through which substances may move from the reservoir. The packaging system preferably includes a cartridge container having a storage area for receiving the cartridge, and a substantially open top with an outer periphery. A peelable lid is sealingly attached to the outer periphery of the container, and a blotter is attached to at least a portion of the inner surface of the peelable lid and preferably spaced inwardly from the outer edge of the lid so as not to interfere with the sealing attachment of the lid to the container. The blotter is thereby held in face-to-face contact with the permeable surface of the cartridge within the packaging system when the lid is in sealed condition and remains captively attached to the lid upon opening of the packaging system.

Abstract: Methods and compositions for semi-permanently conditioning hair by treating the hair, preferably following shampooing, with a composition including a low viscosity oil-in-water emulsion of a mixture of two polysiloxane polymers, that is, a hydroxy terminated dimethyl polysiloxane and a methyl hydrogen polysiloxane, the composition being at an acid pH. It is a feature of this invention that the polysiloxane polymers in the hair-treating composition are in an unreacted or non-crosslinked state. After the composition is applied to the hair, the crosslinking of the two polysiloxane polymers takes place on the hair resulting in a semi-permanent conditioning effect. Although some crosslinking of the polymers will occur while drying the treated hair at room temperatures, increased crosslinking occurs when the hair is blow dried using heated air.
