Abstract: Cellobiose esters and particularly &agr; cellobiose octanonanoate has been found able to structure water-immiscible liquids well, and in particular can produce clear structured emulsions. However, such emulsions tend to lose clarity or structural strength during storage. Deviating from &agr;-cellobiose octanonanoate can result in impaired clarity and/or impaired hardness of emulsion sticks. However, acylated cellobiose which contains acyl substituents of formula —O—CO—R in which R represents an n-octyl residue and the percentage Y of the nonanoate acyl substituent —O—CO—R at the anomeric carbon is at least 60% and the percentage A of &agr; anomer is greater than the anomer and not higher than A=74.5 +0.2Y when Y is up to 92% and not higher than A=161−0.74Y when Y is greater than 92% offers the production of sticks combining structurant stability with product clarity and hardness.

Abstract: Structured, antiperspirant microemulsions possibly in the form of liquid crystals, containing cosmetic oils, a solution of antiperspirant salt in a hydrophilic solvent, a surfactant and an oil structurant are provided. These microemulsions can be used in different types of Solid applicators such as soft solid and, particularly desirably, firm stick applicators. The structured microemulsions are preferably clear by virtue of a suitable choice of oil, solvent and structurant.

Abstract: A firm solid antiperspirant composition having a continuous phase comprising water-immiscible liquid containing i) one or more gelating structurant materials which form a network of fibres within the liquid, and ii) a polymeric thickener which has an organic polymer backbone containing at least five monomer repeat units, which polymer has the ability to increase the viscosity of the water-immiscible liquid in the absence of the gelating structurant materials; and iii) an antiperspirant active dispersed in the continuous phase, said composition being free from or containing less than 3% by weight of a fatty alcohol that is solid at 20° C.
