Abstract: A mascara composition for curling and thickening eyelashes comprising: a waxes-in-water emulsion of at least one mixture of hard waxes (I), the mixture of waxes (I) containing at least three waxes having melting points ranging from 77° C. to 110° C., the mixture of waxes (I) is present in a content of at least 10% by weight relative to the total weight of the composition, and the mixture of waxes (I) is in the form of particles of at least 1 &mgr;m in size, and at least 0.1% by weight of a polymer system containing at least one film-forming polymer, where the polymer system is capable of forming a film which produces, at a concentration of 7% in water, a greater than 1% retraction of isolated stratum corneum at 30° C. and under a relative humidity of 40%.

Abstract: The invention relates to a process for the preparation of a plaster-based solid composition, in particular a cosmetic composition, this process comprising the following steps: a pulverulent mixture comprising at least calcium sulphate hemihydrate in powder form is prepared, an aqueous phase is added to the pulverulent mixture, the pulverulent mixture and the aqueous phase are blended together so as to obtain a castable mixture, the castable mixture is poured into a mould, the mixture is left to cure by hydration of the calcium sulphate hemihydrate into calcium sulphate dihydrate, characterized in that a non-aqueous liquid preserving system is added to the pulverulent mixture before adding the aqueous phase. The invention also relates to a composition, in particular a cosmetic composition, which can be obtained by the process.

Abstract: The invention relates to a binder composition comprising:(i) at least 20% by weight, relative to the total weight of the binder composition, of at least one ester which is liquid at room temperature comprising at least two hydrocarbon chains, each hydrocarbon chain independently containing at least 10 carbon atoms, the ester containing no hydroxyl groups and having a wettability ranging from 30 seconds to 10 minutes,(ii) the possible difference to 100% by weight, relative to the total weight of the binder composition, of at least one fatty substance which is compatible with the ester, in an anhydrous composition in powder form comprising at least one pulverulent compound,and its use as an agent for aiding the dispersion of the anhydrous composition in powder form and/or for improving the solidity and/or strength of an anhydrous composition in compact powder form.
