<p>Emulsion type cosmetic composition comprises: an aqueous phase; particles including a hard wax, preferably an aqueous dispersion of particles of hard wax having a melting temperature of >= 60[deg] C; and an emulsifying system that is adapted to disperse wax and comprises an anionic surfactant having a hydrophilic-lipophilic balance, at 25[deg] C, of >= 8 and comprising alkyl phosphate and nonionic surfactant having a hydrophilic-lipophilic balance, at 25[deg] C, of >= 8 and comprising 8-24C fatty alcohol ethers and polyethylene glycol having 1-10 units of ethyleneglycol. The amount of hard wax is >= 10 wt.%. 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, which is greater than the melting temperature of the hard wax, adding the emulsifying system, >= 25 wt.% of water, colorant 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 = 1.75, preferably 1/3 to 1.25 such that the weight ratio of the waxes is more than the additional wax/emulsifying system, stirring the mixture at a temperature, which is 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 from the first phase, and 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 then adding preservatives.</p> |
