Abstract
An epilatory composition, substantially provided as flat strips, comprises a gel-like matrix material, for example a rosin-based or sugar-based material and, mixed with the matrix material, a particulate material, for example colloidal particles of fumed silica, and a polyethylene in the form of a homopolymer. The particles reduce the tendency of the epilatory composition to flow, under warm ambient conditions with improved efficacy over known epilatory compositions.

An epilatory composition comprising a rosinous or sugar-based matrix material in admixture with particulate silica, and a polyethylene in the form of a homopolymer.
An epilatory composition comprising:
- a rosinous or sugar-based matrix material in admixture with a particulate colloidal silica present in an amount up to 10% wt/wt of the epilatory composition, and
- a polyethylene in the form of a homopolymer, wherein the polyethylene is linear or non-branched, has a molecular weight from about 250 to about 800 unified mass units, and is present in an amount in the range 0.1% to 5% by weight of the composition,
- wherein the ratio of silica to polyethylene the epilatory composition is in the range 6.0:1.0 to 6.0:5.0 and wherein at least 60% of the weight of the epilatory composition is provided by rosinous material.
