PROCESS OF FORMING CRYSTALS FOR USE IN A PERSONAL CARE COMPOSITION

摘要

A method of making a stable detersive surfactant containing personal care composition comprising the steps of emulsifying a stabilizing agent in the presence of anionic surfactant to form an emulsion containing droplets having a particle size of from about 0.1 to about 10 um. These particles are then cooled to form a stabilizing premix at a rate of about 10 to about 1000 C/min to form crystals from the droplets, the crystals having a maximum dimension of about 0.1 to about 3 um. These crystals are then added to a detersive surfactant containing personal care composition to increase stability.

1. A method of making a stable, detersive surfactant containing anti-microbial personal care composition comprising:
(a) emulsifying from about 4% to about 30% of a stabilizing agent in the presence of from about 2% to about 30% of an anionic surfactant to form an emulsion at a temperature of about 5 to about 20° C. above the melting point of the stabilizing agent, to form an emulsion wherein
(i) the stabilizing agent is ethylene glycol distearate;(ii) the anionic surfactant is selected from the group consisting of an alkyl sulfate, an alkyl ether sulfate, and a combination thereof, and(iii) the formed emulsion contains droplets having a particle size of about 0.1 to about 10 um; (b) cooling the emulsion to form a stabilizing premix at a rate of about 10 to about 1000 C/min to a temperature of about 5° C. to about 30° C. below the melting point of ethylene glycol distearate to form crystals from the droplets, the crystals having a maximum dimension of about 0.1 to about 3 um and an aspect ratio of about 2 to about 1000; and (c) adding the stabilizing premix to a detersive surfactant containing anti-microbial personal care composition.
