Description of the invention
The present invention relates to a new cosmetic composition containing in a cosmetically acceptable medium at least one specific aminosilicone and at least one thickener, the use of this composition and a method of treating keratin substances.
It is well known that hair that has been sensitized to varying degrees (i.e. damaged and / or brittle) by the weather or by mechanical or chemical treatments such as dyeing, bleaching and / or perming is often difficult to detangle. and to arrange and lose their delicacy.
It has long been recommended in compositions for washing or caring for keratin substances such as hair, the use of conditioning agents, especially cationic polymers or silicones, to facilitate the detangling of the hair and to make it soft and supple. However, the cosmetic advantages mentioned above are unfortunately also accompanied by certain cosmetic effects on dry hair, which are considered undesirable, namely the weight of the hairstyle (lack of lightness of the hair), lack of smoothness (hair heterogeneous from the root to the tip).
Moreover, the use of aminosilicones for this purpose has various drawbacks. Due to their strong affinity for hair, some of these silicones deposit to a large extent on repeated application and lead to undesirable effects exhibited by the hairstyle such as unpleasant feel, weight, hair stiffness and inter-fiber adhesion. These disadvantages are exacerbated by fine hair that lacks bounce and fluffiness.
Moreover, while aminosilicone microemulsions are particularly effective, their incorporation into hair compositions is sometimes difficult, these compositions proving to be less effective, especially short-lived on the hair.
In summary, it appears that the present cosmetic compositions containing aminosilicones are not entirely satisfactory.
The Applicant has now found that the combination of a particular amino silicone with thickeners overcomes these drawbacks.
Thus, in the course of extensive research into this problem, the Applicant has found that a composition containing at least one aminosilicone as defined below and at least one thickener allows the reduction or even removal of lack of shine, smoothness and tenderness from the hair, while fully preserving other beneficial cosmetic properties that are associated with the compositions containing the silicone.
The compositions according to the invention lead to an optimization of the deposition of silicone on keratin substances.
The compositions according to the invention provide improved cosmetic properties (lightness, delicacy, detangling, natural feel and great manageability, shine), moreover, the effects are permanent and remain. In particular, these effects are resistant to repeated shampooing.
Furthermore, when applied to the skin, the compositions according to the invention, in particular in the form of a lathering bath or shower gel, improve the delicacy of the skin.

PL 206 980 B1
Another object of the invention relates to a method of treating keratin substances, such as hair, by applying a cosmetic composition as defined above to said keratin substances and then optionally rinsing with water.
The various objects of the invention will now be described in detail. All the meanings and definitions of the compounds used in the present invention given below are valid for all subjects of the invention.
In the context of the present application, a thickener is understood to mean any agent intended to increase the viscosity of the composition.
According to the present invention, keratin substances are understood to mean hair, eyelashes, eyebrows, skin, nails, mucous membranes or hairy skin, in particular hair.
Preferably the C1-C4 alkoxy group is methoxy.
The hydroxy / alkoxy molar ratio is in particular from 0.2: 1 to 0.4: 1, preferably from 0.25: 1 to 0.35: 1, in particular equal to 0.3: 1.
The weight average molecular weight of the silicone is preferably 2,000-1,000,000, and even more preferably 3,500-200,000.
The hydroxy / alkoxy molar ratio is generally from 1: 0.8 to 1: 1.1, preferably from 1: 0.9 to 1: 1, and even more preferably equal to 1: 0.95.
The weight average molecular weight of the silicone is preferably 2,000-200,000, and more preferably 5,000-100,000, and even more preferably 10,000-50,000.
The weight average molecular weights of these aminosilicones are measured by Gel Permeation Chromatography (GPC) at ambient temperature as the polystyrene equivalent. The columns used are the μ columns. styragel. The eluent is THF, the flow rate is 1 ml / minute.
200 μΐ of a 0.5% (w / w) solution of silicone in THF is injected. Detection is by refractometry and UV rays.
Commercial products corresponding to these formulas 1 or 2 silicones may contain in their composition one or more other aminosilicones whose formula is different from formulas 1 and 2.
The product containing amino silicones of the formula I is proposed by Wacker under the name Belsil® ADM 652.
The product containing amino silicones of the formula 2 is proposed by Wacker under the name Fluid WR 1300®.
When these aminosilicones are used, a particularly interesting application form is in the form of an oil-in-water emulsion. The oil-in-water emulsion may contain one or more surfactants. Surfactants can be of any nature but are preferably cationic and / or nonionic.
The numeric average particle size of the silicone in the emulsion is generally 3-500 nanometers.
Preferably, especially as aminosilicones of the formula II, microemulsions are used in which the average particle size is 5-60 nanometers (including the limits), more particularly 10-50 nanometers (including the limits).
Thus, according to the invention, the aminosilicone microemulsions of the formula 2 proposed under the names Finish CT 96 E® or SLM 28020® by the company Wacker can be used.
Preferably the aminosilicone is selected such that the angle of contact with water of a hair treated with a composition containing 2% (active ingredient) of said silicone according to the invention is 90-180 ° (including limits), and is preferably 90-130 ° (limits included).
For measuring the contact angle, the aminosilicone is preferably dissolved or suspended in an aminosilicone solvent or an aminosilicone emulsion (especially hexamethyldisiloxane or water depending on the hydrophilic group of the silicone).
Preferably a composition containing the aminosilicone (s) of formula 1 or 2 is such that the angle of contact with water of the hair treated with said composition is 90-180 ° (including limits) and preferably 90-130 (including limits).
Contact angle measurement is based on immersing the hair in distilled water. It involves assessing the force exerted by water on the hair during its immersion in distilled water and during its retraction. The forces measured in this way are directly related to the contact angle θ between the water and the hair surface. A hair is considered hydrophilic when the angle θ is 0-90 ° (limits included), and hydrophobic when this angle is 90-180 ° (limits included).
PL 206 980 B1
The test is carried out on strands of natural hair that have been discolored under the same conditions and then washed. Each 1 g lock is placed in a crystallizing dish 75 mm in diameter, and then uniformly covered with 5 ml of the test formulation. The strand is left for 15 minutes at ambient temperature, then rinsed with distilled water for 30 seconds. The strand is left in the air until it is completely dry.
In each assessment, 10 hairs subjected to the same treatment are analyzed. Each sample, attached to a precision microbalance, is immersed with its tip in a container filled with distilled water. This DCA scale ("Dynamic Contact Angle Analyzer") from CAHN Instruments allows the force (F) exerted by the water on the hair to be measured.
Simultaneously, the circumference of the hair (P) is measured by microscopic observation.
The averaged wettability force acting on 10 hairs and the cross-section of analyzed hair allow to obtain the angle of contact between the hair and water according to the formula:
F = P * ΓΙν * cosθ where:
F is the wettability force expressed in newtons,
P hair circumference in meters, <sub>2</sub>
ΓΙν * liquid / vapor interfacial tension for water in J / m and θ contact angle.
The product SLM 28020 from Wacker with 12% in water (i.e. 2% aminosilicon) gives a contact angle of 93 ° according to the test given above.
The product Belsil ADM 652 from Wacker with 2% in hexamethyldisiloxane (i.e. 2% aminosilicon) gives a contact angle of 111 ° according to the test given above.
The amino silicone (s) of formula 1 or 2 are preferably used in an amount of 0.1 to 15% by weight, especially 0.5-10% by weight, based on the total weight of the composition.
By the expression "associative thickener," according to the invention is meant an amphiphilic thickener which comprises both hydrophilic moieties and hydrophobic moieties, in particular comprising at least one C8-C30 fatty chain and at least one hydrophilic moiety.
Nonionic amphiphilic polymers containing at least one fatty chain and at least one hydrophilic moiety are preferably selected from:
