Assembly, used to make up keratin fiber e.g. eyelashes, comprises emulsion type cosmetic composition with aqueous and fatty phase and emulsifying system and units to heat composition such that fatty phase changes from solid to liquid state

摘要

Coating assembly comprises an emulsion type cosmetic composition for coating keratin fibers, and units for heating the composition such that a portion of the fatty phase changes from a solid state to a liquid state. The emulsion type cosmetic composition comprises: an aqueous phase; a fatty phase comprising particles including hard wax, preferably an aqueous dispersion of particles of hard wax; and an emulsifying system that is adapted to disperse the hard wax and comprises nonionic surfactant having a hydrophile-lipophile balance value of = 8 preferably = 10 at 25[deg] C. Coating assembly comprises an emulsion type cosmetic composition, preferably mascara for coating keratin fibers, and units for heating the composition such that at least a portion of the fatty phase changes from a solid state to a liquid state. The emulsion type cosmetic composition comprises: an aqueous phase; a fatty phase comprising particles including at least one hard wax, preferably an aqueous dispersion of particles of hard wax, where the hard wax has a melting temperature of = 60[deg] C and is present in an amount of = 10 wt.%; and at least one emulsifying system that is adapted to disperse the hard wax and comprises at least one nonionic surfactant having a hydrophile-lipophile balance value of = 8 preferably = 10 at 25[deg] C. An independent claim is included for preparing the emulsion type cosmetic composition comprising heating the hard wax and optionally additional wax in the aqueous phase at a temperature greater than the melting temperature of the hard wax, adding the emulsifying system, = 25 wt.% of water, coloring material and optionally other thickening nature compound (such as gums, fillers, pasty fatty substances and water-soluble film-forming polymers) to the aqueous phase, where the total content of hard waxes and optionally additional waxes and the total content of emulsifying system are 1/2-6, preferably 2/3-5, stirring the mixture at a temperature greater than the melting temperature of the hard wax, disposing the aqueous phase, to a second phase, comprising an aqueous dispersion of particles of film forming polymer, controlling the temperature to 0-45[deg] C, preferably 0-20[deg] C for the preparation of first phase and the second phase that is different, contacting the first and second phases at a temperature of 0-45[deg] C, preferably 0-20[deg] C, stirring the mixture until the temperature of mixture is regulated to 0-45[deg] C preferably 0-20[deg] C, and adding preservatives.
