Abstract: Fragrance leaches rapidly from capsules having shells made from cross linked gelatin into volatile silicone oils. Unfortunately such oils are much favored for anhydrous antiperspirant compositions. The rate and extent of leaching can be ameliorated greatly or nearly halted by employing as carrier oil, an ester oil or an ether oil, even in the presence of a significant fraction of volatile silicone oil. Consequently, the capability of antiperspirant compositions to generate detectable fragrance over an extended period after application to the skin is improved by employing ester or ether oil as all or part of the carrier liquid in which the antiperspirant is suspended.

Abstract: It is desirable for antiperspirant or deodorant roll-on compositions to be able to deliver fragrance over an extended period of time after application, but previously contemplated encapsulates were based on starch or similar water-soluble or dispersible shell materials, rendering them ineffective in aqueous emulsions. Capsules of fragrances in cross-linked coacervated gelatin shells satisfying defined particle size, shell thickness and hardness criteria enable roll-on compositions to be incorporated into aqueous antiperspirant or deodorant compositions encapsulated fragrance that can be released after the composition has been topically applied to skin.

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—RX in which RX represents a branched C6 to C11 alkyl 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.
