Method of manufacture of antiperspirant salts

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.

An antiperspirant or deodorant composition comprising i) an antiperspirant or deodorant active, ii) a liquid carrier for the antiperspirant or deodorant active, and iii) fragrance in which the fragrance comprises a mixture of first and second fragrances, respectively (iiia) and (iiib), the first fragrance (iiia) being free from encapsulation and comprising fragrance components having a boiling point of higher than 250&#xb0; C. at 1 bar pressure in a weight proportion of greater than 65% and the second fragrance (iiib) being encapsulated in a water-insoluble shear-sensitive encapsulating material and comprising fragrance components having a boiling point of greater than 250&#xb0; C. at 1 bar pressure in a weight proportion of less than 65%.

Segregation of antiperspirant actives suspended in anhydrous compositions employing ester oils or non-volatile silicone oils having a refractive index of at least 1.5, preferably together with an alcohol oil, gelled with a fibre-forming amide gellant can be inhibited by including a segregation inhibitor, especially an arylene-alkylene block copolymer, such as a tri-block copolymer e.g. a styrene/ethylenebutylene/styrene copolymer or a styrene/butylene copolymer.
