Description

EXAMPLE 1EYELINER ACCORDING TO THE PRESENT INVENTION

[0107] A cosmetic composition in the form of aqueous gel was prepared according to the present invention with the following percentage composition by weight:

TABLE-US-00001 iron oxide (black) 18% acrylic copolymer Daitosol 5000 AD .sup.20% (*) xanthan gum 0.3% potassium cetyl phosphate 1.4% ethyl alcohol 3.0% butylene glycol 1.0%; caprylyl glycol 0.65% pentylen glycol 3.0% NaOH 0.08% phenoxyethanol 0.85% sodium dehydroacetate 0.2% laureth-21 0.12 water complement to 100%. (*) percentage by weight of dry polymer referred to the weight of the cosmetic composition.

[0108] The Brookfield dynamic viscosity of the aqueous gel was equal to 1200 cPs (measured at 25 C., speed: 50 rpm, rotor S04) and a pH of 7.2.

[0109] The efficacy of the composition as peel-off eyeliner was tested as follows.

[0110] A layer of the cosmetic composition was applied at room temperature on the skin of the back of a hand (stroke length: 40 mm; stroke width: 2 mm. 5 minutes were waited to allow the solvent evaporation and the formation of the colored decorative stroke.

[0111] The decorative stroke was bright and shiny.

[0112] Then, the decorative stroke was wetted with water using a wet swab. The mere contact with water did not give rise to smears of color.

[0113] The wet decorative stroke was then slightly scratched with a fingernail, at one end, to pull out a small strip of film from the skin. By grasping it with the fingers on the detached strip, the film was peeled, removing it completely from the skin, without fragmentation.
