process for producing an antiperspirant containing emulsion, antiperspirant emulsion, and non-therapeutic use of an antiperspirant emulsion

摘要

"Process for the production of an emulsion containing antiperspirant, antiperspirant emulsion, and cosmetic use thereof". antiperspirant emulsions which exhibit excellent phase stability even in the presence of an effective concentration of antiperspirant salts in solution which are thickened and obtainable by dispersing a hydrated polymer and especially an amphoteric or cationic modifier starch into an aqueous emulsion forming a viscous emulsion, often at elevated temperature, subjecting the emulsion to high shear, thereby reducing the droplet size of the dispersed oil phase, bringing the emulsion below 40 ° C and introducing the antiperspirant, preferably in aqueous solution. the viscous emulsion blended under high shear desirably has a sheer stress of 10 to 500 pa. The resulting emulsions show good phase stability even when they contain aluminum / zirconium antiperspirant salts that promote instability and even at high storage temperatures such as 50 ° C.
