BACKGROUND ART
In order to improve the cosmetic properties of the compositions for application to sensitized hair, i.e., hair which is damaged or weakened, in particular through the chemical action of environmental agents and/or of hair treatments such as permanent-waving, dyeing or bleaching, it is known to introduce into these compositions conditioning agents. The main purpose of these conditioning agents is to rectify or limit the undesirable effects induced by the various treatments or types of attack to which the hair fibers are more or less repeatedly subjected to and, of course, they can also improve the cosmetic behaviour of natural hair.
The conditioning agents most commonly used to date are cationic polymers, silicones and/or silicone derivatives which impart to washed, dry or wet hair a disentangling, softness and a smoothness which are markedly enhanced in comparison to what can be obtained with corresponding compositions which do not contain them.
In recent years, consumers are increasingly seeking cosmetic products formed from/that comprise natural constituents or constituents of natural origin, in particular products that do not comprise silicone. Efforts have been made to hair care products containing conditioning agents of natural origin, for providing to the hair fibers equivalent conditioning effects as those containing silicones as conditioning agent.
