(57) Structured antiperspirant emulsion formulations for topical application to human skin in a cosmetic method for controlling sweat and body odour generation comprising an hydrophilic phase containing an aluminium and/or zirconium astringent salt dispersed in a structured continuous oil phase can suffer from problems of impaired sensory properties and impaired efficacy (sweat reduction).
Such problems are ameliorated or overcome in structured antiperspirant emulsions in which

• i) the hydrophilic phase comprises from 25 to 55% by weight of the emulsion;
• ii) the hydrophilic phase contains from 0 to not more than 15% polyhydric alcohol by weight of the emulsion;
• iii) the emulsifier comprises an alkyl dimethicone copolyol;
• iv) the weight ratio of the hydrophilic phase to the emulsifier is selected in the range of from at least 60:1
• v) the structurant comprises an acylated sugar and
• vi) the water-immiscible oil and the structurant are present in a weight ratio of from 1.5:1 to 8.5:1.
