Antiperspirant compositions herein comprise an antiperspirant active, together with a carrier and a structurant for the carrier which comprises an organic wax having a melting point of from 40 to 90° C. of which at least 60% of the weight of the wax is provided by at least one aliphatic ester satisfying the formula:in which n is from 9 to 39 and m is from 0 to 35 to form a solid or a soft solid. The compositions can be anhydrous, in the form of a suspension of antiperspirant active, or can comprise aqueous emulsions.The formulations structured by the selected waxes provide lower visible deposits on topical application compared with conventional wax-structured formulations and the waxes are effective at structuring/thickening at a proportion below that in conventional wax-structured formulations.It is especially desirable to employ emulsion formulations comprising a continuous phase which comprises from 10 to 35% volatile silicone oil, and from 5 to 15% non-volatile hydrophobic oil, from 40 to 75% of ta disperse aqueous phase which contains from 1 to 35% of an antiperspirant or deodorant active, from 7 to 25% of a wax structurant, from 0.1 to 10% of an emulsifier, and preferably contains up to 5% insoluble particulate materials, % s being by weight based on the composition. |
