    摘要: Anhydrous cosmetic stick compositions containing a continuous phase of a water-immiscible cosmetic oil structured by a fibre-forming amido structurant and containing a suspended particulate antiperspirant or deodorant can suffer from either somewhat poor physical stability when formed, or preparative difficulties using conventional processes for making stick compositions or opaqueness. The problem can be ameliorated or overcome by the use of a combination of amido structurants comprising (i) an N-acylaminoacid amide in which the N-acyl substituent has the formula —CO—RX in which RX represents a branched C6 to C11 alkyl group in combination with a further amido structurant (ii), selected from (iia) N-acylaminoacid amides other than (i), (iib) cyclodipeptides and (iic) a 1,2-di amido-substituted cyclohexane.

    摘要: Antiperspirant emulsions which exhibit excellent phase stability even in the presence of an effective concentration of antiperspirant salts in solution and which are thickened are obtainable by dispersing a hydratable polymer and particularly an amphoteric or cationic modified starch in an aqueous emulsion forming a viscous emulsion, often at an elevated temperature, subjecting the emulsion to high shear, thereby reducing the droplet size of the dispersed oil phase, bringing the emulsion to below 40° C. and introducing the antiperspirant, preferably in aqueous solution. The viscous emulsion subjected to high shear mixing desirably has a Sheer Stress of 10 to 500 Pa. The resultant emulsions show good phase stability even when they contain aluminium/ zirconium antiperspirant salts that promote instability and even at elevated storage temperatures such as at 50° C.
