USE OF CARBON BLACK AS AN AGENT FOR ENHANCING THE WATER RESISTANCE OF A MAKE-UP COMPOSITION OF
KERATINIC MATERIALS
The present invention relates to the use of carbon black as an agent for improving the water resistance of a makeup composition for keratin materials, and to a method for improving the water resistance of a make-up composition of keratin materials.

 The particular use of carbon black as a color pigment is well known in cosmetics. Indeed, the makeup compositions generally contain it so as to obtain a black color of the keratin materials, in particular eyelashes.

 Other black pigments, such as iron oxide, can also be used in cosmetics.

 The Applicant has surprisingly found that the use of carbon black in comparison with that of iron oxide makes it possible to obtain a better water resistance of a makeup composition comprising a film-forming polymer in aqueous dispersion, deposited on keratin materials, and more particularly on eyelashes.

 The subject of the present invention is therefore a use of carbon black as an agent making it possible to improve the water resistance of a makeup composition for keratin materials comprising at least one film-forming polymer in aqueous dispersion.

 Another object of the invention is a method for improving the water resistance of a make-up composition for keratin materials.

 Other objects, features, aspects and advantages of the invention will emerge even more clearly on reading the description and the various examples which follow.

 The glass plate is then placed in a large crystallizer filled with water at room temperature, placed on a magnetic stirrer.

 The behavior of the film is observed with agitation of the water and the time at which the film is detached or tears is measured.

Lacquer containing 5% black iron oxide has the same color intensity as lacquer containing 1.5% carbon black. In this case, the lacquer with the carbon black has a water resistance similar to that of the lacquer containing iron oxide.

 At the same pigment content (5%), the lacquer containing carbon black provides a significantly better water resistance compared to that of the lacquer containing black iron oxide.
