Description

EXAMPLE

[0073] A preparation that is suitable as a pencil lead mass was produced. The ingredients are indicated in the following table, the amounts in each case being the % by mass (mass relative to the total composition).

TABLE-US-00001 Phase A Black pigment CI77499 18.13 Euphorbia cerifera wax 3.63 Synthetic wax schmp. 1.81 Synthetic wax schmp. 7.25 Polyglyceryl-5 dioleate 2.72 Sucrose polystearate 2.72 Dimethicone 3.63 Butylene glycol cocoate 0.91 Phase B Aqua 38.24 Butylene glycol 6.35 Phenoxyethanol 0.50 Tris(hydroxymethyl)aminomethane 0.68 Polyurethane 35 3.36 Styrene/acrylates/ammonium 10.07 Methacrylate copolymer

[0074] To produce the preparation, euphorbia cerifera wax and the two synthetic waxes were mixed with dimethicone, then the oil butylene glycol cocoate followed by polyglycerol 5 dioleate, and sucrose polystearate were added as emulsifiers, and the resulting mass was heated to produce a molten wax phase. The molten mass was then homogenized with the black pigment. This produced wax phase A. Then polyurethane and styrene/acrylates/ammonium methacrylate copolymer were mixed together, each as a 40% aqueous dispersion, and phenoxyethanol was added as a preservative. Tris(hydroxymethyl)aminomethane was also added to adjust the pH. The aqueous phase was then heated to a temperature of about 70° C. and the wax phase, which has a temperature in a range from 85° C. to 95° C., was added slowly with constant stirring. In order to form a stable and homogeneous emulsion, the mixture was homogenized in a sealed system by a dispersing disk for a while, keeping the temperature of the mixture in a range from 85° C. to 95° C. Next, the molten mass was poured into a casting mask to form a pencil lead and allowed to cool at room temperature.

[0075] After cooling, a pencil lead was produced that could be placed in a makeup pencil and used as an eyeliner.

[0076] With the eyeliner lead produced in this manner, a black line was drawn around the eyes of test subjects and the appearance was tested immediately after application and six hours later. This produced a strongly covering, very homogeneous line that had practically not changed after six hours.

[0077] The application of the eyeliner was perceived by the test subject as very pleasant. The eyeliner line remained in place, required no touch-up, and did not migrate into the wrinkles. After drying, the test subject rubbed across the line, and the line practically did not change.
