<p>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.</p> |
