TECHNICAL FIELD OF THE INVENTION

The present invention relates generally to aqueous cosmetic compositions, especially compositions for treating hair, that include water-soluble organosilicon compounds that are unpolymerized or relatively unpolymerized.

[0002]

[Prior art]

It is common practice to make cosmetic compositions for treating hair using organic compounds such as polymers. For example, to fix the shape of the hairstyle,
A polymer is used that dries to a solid material. These substances are also used to obtain a shape-retaining effect. Polymeric substances, such as polysiloxanes, also for hair,
It is especially used for providing a care effect to hair that is damaged or difficult to disentangle. Cosmetic compositions containing these polymers are applied to hair that is left to dry or that is rinsed before proceeding to the drying process. The use of polymeric compounds presents several drawbacks. The first drawback is that the use of the polymer in the composition beyond a certain concentration makes it difficult to apply the resulting composition as a result of the increased viscosity of the composition.
Due to the difficulty of applying the composition, it is over-applied on some parts of the hair, resulting in cosmetic cosmetic defects, which also means that less composition is applied to other parts of the hair. It also means that the effect of is reduced. A second drawback is that these compositions are often difficult to use. The reason is that the polymer compounds are poorly water-soluble and the use of organic solvents or mixtures of organic solvents is necessary. The use of organic solvents inevitably leads to several problems, for example environmental problems and effects on the cosmetic quality of the hair.

To overcome these drawbacks, attention has been directed to using partially water-soluble polymeric compounds. For example, certain polymeric compounds can be used in water without the use of any cosolvents. In this case, there is a limit in that these polymer compounds are partially or wholly removed by rinsing the hair. Therefore, in this case, the effect of the polymer compound after rinsing is very limited. After all, this limits the effect of rinse-out treatments (shampoo or conditioning), and the user loses the effect of the treatment by washing, so that these can be used in a leave-in form. Reduce the benefits of using the composition of Therefore, efforts have been made to find compounds or cosmetic composition formulations which can be used in water and retain their effect even after rinsing the hair. For example, U.S. Pat. No. 4,344,763 (Gillette) describes a cosmetic composition comprising an organosiloxane monomer dissolved in alcohol, such as an aminoalkylalkoxysilane and an organic titanate. More particularly, the patent wets the hair with water and then in isopropanol 0.5% to 15% aminoalkylalkoxysilane and 0.005% to 1.5% organic titanate by weight. Describes a method of shaping hair, which comprises applying a solution containing, and then shaping the hair into the desired shape.

According to the method, it is especially recommended to keep the isopropanol solution protected against any moisture. “A new type of hair fixative with semi-permanent wave properties (Nouveaux typ
es de fixateurs pour cheveux ayant des proprietes semi-permanentes) ”,
M. SARDO-Parfum Cosmetique Saveur France, Vol. 2, No. 5 (1972) also describes compositions of this type. Many products are not effective due to the instability of the aqueous composition produced. Patent EP-113 992 also comprises (A) a siloxane oligomer containing at least one nitrogen-hydrogen bond and (B) an immediately hydrolyzable additive selected from titanates, zirconates, vanadate and germanates and mixtures thereof, Disclosed is a method of co-fixing and conditioning hair using a composition that is stable in the absence of moisture. The solvent for the composition is an aliphatic hydrocarbon or an aliphatic halohydrocarbon, preferably 1,1.
, 1-trichloroethane. After application of the composition to the hair, the hair is allowed to crosslink with the siloxane oligomer and the immediately hydrolyzable anhydrous additive in a humid environment.

[0005]

[Problems to be Solved by the Invention]

Therefore, there is a need for a stable cosmetic composition, which is essentially aqueous, in particular in the form of rinsing or non-rinsing of the hair, in order to obtain a sufficient cosmetic effect, in particular for treating the hair. Accordingly, one subject of the present invention is a stable aqueous cosmetic composition, in particular a hair treatment and hair care cosmetic composition, which overcomes the disadvantages of the prior art. More particularly, one subject of the present invention is a stable aqueous hair treatment and hair care cosmetic composition which gives the hair a long lasting styling effect and a pleasant sensation.

[0006]

[Means for Solving the Problems]

Surprisingly, the Applicant has found that a water-soluble, unpolymerized or relatively unpolymerized polymer which contains at least one basic chemical functional group and is partially neutralized with a particular agent. By using an organosilicon compound in the composition, a cosmetic composition is prepared which effectively has a rinse resistance action without the risk of the problem of electrification when hair is overlapped, and which does not require the use of an organic solvent. I found it possible. It has been found that the application of these compositions results in a pronounced cosmetic effect, there is no problem of overlapping and the effect of the composition opposes rinse and wash.
