Cosmetic product containing shellac

A cosmetic product containing shellac, wherein shellac is present in the aqueous phase, where the pure shellac content is

• in the range of 0.1 to 20 wt % in an O/W emulsion,
• in the range of 0.1 to 15 wt % in a W/O emulsion,
• in the range of 0.1 to 10 wt % in a hydrogel,
• and the oily phase or the aqueous phase or both phases contain additional cosmetic active ingredients or vehicles in the range of 1 to 20 wt %,
• and all amounts are based on the weight of the total composition,
• prepared by
• a) preparing an emulsion or a hydrogel in the usual way by mixing a primary emulsion phase, containing the cosmetic active ingredients and additives provided therein, with a secondary emulsion phase, containing the cosmetic active ingredients and additives provided therein;
• or mixing a gel-forming substance with water and adding the cosmetic active ingredients and additives provided therein;
• and
• b) preparing a 5 wt % to 60 wt % aqueous shellac solution or dispersion by mixing pure shellac dry solids having a molecular weight of approximately 1000 with water in the presence of a water-soluble film-forming substance in the range of 0.1 to 3 wt % and a gel-forming substance that is stable in an acidic pH range in the range of 0.1 to 1 wt % plus an acid to adjust the pH to 2 to 4.2 while stirring at 150 to 1000 rpm for a period of 5 to 60 minutes at 20 to 45° C.;
• and
• c) heating the emulsion or the gel from step a) to a temperature in the range of 35° C. to 45° C. while stirring;
• and
• d) adding the shellac solution or dispersion from step b) while stirring at 150 to 1000 rpm for a period of 5 to 60 minutes at 35° C. to 45° C.;
• and then
• e) cooling the resulting product to ambient temperature.

A method of preparing a cosmetic product containing shellac, comprising the following steps:

• a) preparing an emulsion or a hydrogel in the usual way by mixing a primary emulsion phase containing the active cosmetic ingredients and additives provided therein with a secondary emulsion phase containing the active cosmetic ingredients and additives provided therein, or mixing a gel-forming substance with water and adding the intended active cosmetic ingredients and additives;
• and
• b) preparing a 5 to 60 wt % aqueous shellac solution or dispersion by mixing pure shellac dry solids having a molecular weight of approximately 1000 with water in the presence of a water-soluble film-forming substance in the range of 0.1 to 3 wt % and a gel-forming substance that is stable in the acid pH range in the range of 0.1 to 1 wt % and an acid for adjusting the pH to a level of 2 to 4.2 while stirring at 150 to 1000 rpm over a period of 5 to 60 minutes at 20 to 45° C.;
• and
• c) heating the emulsion or the gel from step a) to a temperature in the range of 35 to 45° C. while stirring, and
• d) adding the shellac solution or dispersion from step b) while stirring at 150 to 1000 rpm during a period of 5 to 60 minutes at 35 to 45° C.;
• and then
• e) cooling the resulting product to ambient temperature.
