The invention relates to a PEG-free O / W emulsifier based on fully neutralized potassium cetyl phosphate and palm glycerides, which is suitable for the production of cosmetic and pharmaceutical emulsions such as creams, lotions and very low-viscosity, sprayable lotions and has very good skin tolerance. The O / W emulsions made from it are characterized by: good viscosity stability, - high pH stability or pH-independent stability, - good temperature stability, - very fine and homogeneous emulsion structures with a glossy surface, - Commercial and logistical advantages with regard to the procurement and storage of a single emulsifier for lotions and creams. - The emulsifier can be used in the fat as well as in the water phase. - Claims of the emulsifier: - Use of the following alcohol components for the phosphoric acid ester portion of the O / W emulsifier: 1. Fatty alcohol C14-C18, preferably C16, plant-based 2. proportion of the fatty alcohol in the phosphoric acid ester is 40-80%, preferably 50-60%, 3. Phosphoric acid ester portion of the new O / W emulsifier neutralized with alkali metal hydroxides to give the corresponding salt, preferably potassium hydroxide. 4. Neutralized phosphoric acid ester is compounded with nonionic W / O emulsifiers, preferably mono- and diglycerides of fatty acids or mixtures, preferably vegetable raw material base ... |
