Antiperspirant formulations

A process for making an anhydrous soft solid antiperspirant formulation in the form of a cream comprising the steps of:

• i) introducing into a mixing vessel a carrier fluid having a refractive index that is less than 0.1 below the refractive index of an aluminum/zirconium astringent salt and comprising an aromatic ester having a melting point of below 25° C. and/or a non-volatile silicone oil having a refractive index of at least 1.5 in an amount of from 50 to 80% by weight;
• ii) introducing into the vessel a wax in an amount of from 4 to 20% by weight comprising an aliphatic ester or monohydric alcohol wax;
• iii) heating the non-polymeric wax until it melts or is miscible with the carrier fluid;
• iv) introducing into the carrier fluid or mixture of carrier fluid and wax a particulate aluminum/zirconium astringent salt in an amount of from 5 to 30% by weight at a temperature above the normal solidification temperature of the formulation and;
• v) introducing the composition into a dispenser whilst the composition is fluid.
