Description

Title of the invention: PROCESS FOR THE TREATMENT OF KERATINIC FIBERS COMPRISING THE APPLICATION OF A COUPLING AGENT AND A PHOSPHOLIPID, COMPOSITION AND USE

The present invention relates to a process for treating keratin fibers, in particular human keratin fibers such as the hair, comprising the application, sequentially or simultaneously, to the keratin fibers of a composition A comprising one or more coupling agents and of a composition B comprising one or more lubricating agents, it being understood that at least one of the compositions A and / or B a saline composition.

The invention also relates to a hair cosmetic composition comprising i) one or more coupling agents and ii) one or more lubricating agents and iii) one or more additional salts, and its use for the treatment in particular the lubrication of keratin fibers , in particular human keratin fibers such as the hair.

It is known to implement methods for treating keratin fibers, in particular to improve the conditioning of the hair. These methods generally consist in the application to keratin fibers of hair compositions comprising cationic or protonable polymers depending on the pH, at high concentrations. These hair compositions certainly have a conditioning power but may remain insufficient for proper shaping and repair of the hair, or weighing down the keratin fibers, for example making them rougher, with an unpleasant feel, more difficult to style. In addition, the fibers are not always suitably lubricated so that the fibers appear rough, are difficult to comb, which causes damage which can lead to breakage of said fibers. Keratin fibers can also carry static electricity which disrupts their styling, their discipline and the behavior of the hairstyle throughout the day, the hair being unruly, misaligned. There is therefore a real need to develop processes for treating keratin fibers which are capable of preserving or even improving the quality of the fiber such as softness, feel, discipline, smoothing, disentangling, shine. , sensitivity to humidity, reduction of frizz, hair strength for example by reducing hair breakage; to decrease the content of cationic polymers.

This (s) goal (s) is (are) achieved by the present invention which relates in particular to a process for treating keratin fibers, in particular human keratin fibers such as hair, comprising application, sequentially or simultaneously, to keratin fibers:

- of a composition A comprising i) one or more coupling agents chosen from cationic polymers, amphoteric or zwitterionic surfactants, and mixtures thereof; preferably from cationic polymers; and

of a composition B comprising ii) one or more lubricating agents, preferably one or more phospholipids, it being understood that at least one of the compositions A and / or B is a saline composition ie that it further comprises iii) a or several additional salts, different from the lubricant (s) ii).

Another object of the invention is a device or kit comprising several compartments in which, in at least one of the compartments, is the composition A as defined above, in another compartment is the composition B as defined above, it being understood that in at least one of compositions A or B there are also iii) one or more additional salts.

Some users of compositions for treating keratin fibers may have more or less sensitized hair, that is to say hair which is generally damaged or weakened by the action of external atmospheric agents such as light and bad weather, and / or the action of mechanical or chemical treatments such as brushing, combing, dyeing, discoloration, perms and / or straightening.

The Applicant has found, surprisingly, that the method according to the invention makes it possible to improve the lubrication of keratin fibers, in particular human keratin fibers such as the hair, which makes it possible to improve the cosmetic properties imparted to keratin fibers such as softness, touch, discipline, straightening, detangling, shine, strength of the hair, especially to sensitized hair. It provides good protection for sensitized hair, while retaining good conditioning power.

The Applicant has also found that the process according to the invention makes it possible to significantly reduce the concentration of cationic polymers, as well as the value of the water footprint compared to a conventional hair conditioning process. The properties have been observed even with a small amount of coupling agent (s) and lubricating agent (s), preferably phospholipids (i.e. less than 1% by weight or even less than 0.8% by weight).

Another object of the present invention relates to a hair cosmetic composition, intended for the treatment of keratin fibers, comprising:

- one or more coupling agents i) chosen from cationic polymers, amphoteric or zwitterionic surfactants, and mixtures thereof; more preferably chosen from cationic polymers;

- one or more lubricating agents ii), in particular one or more phospholipids; and - one or more additional salts iii), different from the lubricant (s) ii), in particular different from the phospholipid (s), chosen from halide salts, salts of C ₁ -C ₆ organic acids, and mixtures thereof ; preferably from alkali metal salts such as sodium chloride; alkaline earth salts such as CaCl ₂ ; salts of organic acids such as sodium citrate, sodium lactate, sodium acetate, and mixtures thereof; more preferably the alkali metal salts and in particular sodium chloride.

The present invention also relates to the use of the hair cosmetic composition of the invention for the treatment of keratin fibers, in particular human keratin fibers such as the hair; preferably for shaping, conditioning, lubrication, and repair of said fibers.
