Abstract
Many cosmetic stick compositions containing a continuous phase of a water-immiscible cosmetic oil structured by a fibre-forming amido structurant and an active cosmetic ingredient either exhibit poor physical stability when formed, or cannot be made readily using conventional processes for making stick compositions. The problem can be ameliorated or overcome by the use of a combination of amido structurants comprising in class (i) an N-acylaminoacid amide in which the N-acyl substituent has the formula —CO—Rin which Rrepresents a branched Cto Calkyl group in combination with a further amido structurant, (class (ii), including a polyamido-substituted cyclohexane, an amido derivative of di or tricarboxylic acids or an hydroxystearamide and particularly employing an N-acylaminoacid amide in which the N-acyl substituent contains a linear alkyl group, or a cyclodipeptide.
