Definitions
- the present invention relates to a process for the cosmetic treatment of keratinous substances, making it possible to provide them, particularly in a durable and reversible manner, with interesting cosmetic properties.
- compositions containing cosmetic active ingredients to provide said keratin materials with all the benefits associated with these cosmetic active ingredients. This is also transposable to other keratin materials such as nails, eyelashes and skin.
- the object of the present invention is to provide a process for the cosmetic treatment of keratin materials, making it possible to provide, in a durable and preferably reversible manner, cosmetic properties, including color.
- the subject of the present invention is therefore a process for the cosmetic treatment of keratinous materials comprising the application on said materials:
- a cosmetic composition comprising at least one graftable entity, comprising at least one unit of formula (la) as defined below:
- a cosmetic composition comprising at least one cosmetic active having at least one unit of formula (Ia).

- products comprising entities capable of forming physical interactions with one another, in particular products comprising units of formula (Ia), can bring cosmetic qualities, including color, to keratin materials, persistent.
- products are in particular characterized by the presence of at least one entity capable of giving 3, preferably 4, hydrogen bonds.
- the ureidopyrimidone entities of formula (Ia) are capable of generating a crosslinked network, by physical associations between molecules / polymers.
- the crosslinking is a physical reticulation, the persistence of the effect is possible while allowing the makeup removal products.
- the elimination of the deposit may consist in particular of a rinsing with a cleaning composition applied at room temperature or at a temperature above 25 ° C., or by the use of a make-up remover, a shampoo, or by using any known breaker hydrogen bonding.

After elimination of the active ingredient, the supramolecular functions are always present and a new cosmetic active can then be reassociated without requiring the keratin substrate to be functionalized again.
- Another advantage of the present invention lies in the possibility of associating different cosmetic actives with each other, provided that they are functionalized by an ad hoc ad hoc supramolecular pattern. Thanks to the present invention, it is possible in the hair field, to improve the properties of the hair, to fight against damage, to moisturize, to treat and strengthen or even repair keratin materials, and to provide them with softness, color and shine in a lasting way so that the effect remains perceptible after at least one shampoo.
