Abstract
A fluid composition is provided in the form of a wax dispersion in a liquid vehicle which is comprised of a single phase. The dispersed phase is a stable microdispersion comprised of particles having a size lower than 0.5 .mu.m. The particles are constituted essentially of a mixture of at least one wax, at least one emulsifying agent and optionally at least one oil and/or at least one liposoluble active ingredient. This mixture has a end melting point greater than 50.degree. C. and lower than 100.degree. C. The composition contains, by weight, from 0.1 to 40% of wax and from 0.01 to 25% of emulsifying agent. The emulsifying agent is a cationic emulsifier. The concentration of oil, when it is present, is less than or equal to 30 weight percent relative to the weight of the wax or mixture of waxes.
