A volatile oil composition includes a vehicle and a silicone elastomer, wherein the vehicle is a volatile oily composition of (a) from 50 to 100% by weight of a mixture of linear paraffins including (i) 90 to 99% by weight of at least one linear paraffin selected from C.sub.8, C.sub.10, C.sub.12 paraffins and mixtures thereof, and (ii) 1 to 10% by weight of a C.sub.14 linear paraffin, and (b) from 0 to 50% by weight of at least one non-volatile oil. The composition may be used in cosmetic compositions such as for making up and/or caring for and/or protecting skin, lips, eyelashes and/or nails, and in antiperspirant/deodorant compositions.

A method for styling hair comprises placing the hair in a desired configuration and applying a hair styling composition to the hair. The hair styling composition comprises a powder of a multistage polymer of a soft polymer of Tg<40° C.; and a hard polymer having a Tg>40° C., and at least 10° C. higher than the Tg of the soft polymer wherein the hard polymer forms a complete or partial shell around the soft polymer the weight ratio of hard polymer to soft polymer being 1.01:1 to 2:1. After exposure to liquid water and drying at temperatures below 100° C., a maximum thermal transition temperature of the multistage polymer in an atmosphere of 0% relative humidity that differs by 20° C. or less from the maximum thermal transition temperature in an atmosphere of 75% relative humidity.
