Abstract
Description
Title of the invention: Cosmetic hair care composition comprising at least one particular amino silicone and at least one polyol, and cosmetic treatment method
[0001] The present invention relates to a cosmetic hair care composition comprising at least one particular amino silicone and at least one polyol.
[0002] The present invention also relates to a method for cosmetic treatment of hair, and more particularly a method for cleaning and / or conditioning hair, comprising the application of a composition according to the invention.
[0003] Hair is sensitive to many types of aggression and can be weakened and damaged to varying degrees by the external environment, in particular by the action of atmospheric agents such as light, atmospheric pollution and bad weather, as well as by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming and / or straightening, or even repeated washing.
[0004] The properties of damaged hair are then degraded and we can observe different manifestations of the damage, such as difficulty in detangling and styling the hair, lack of softness of the hair, hair which can in the long run become dry, brittle or dull, especially in fragile areas, and more particularly at the ends.
[0005] To overcome these drawbacks, and in particular to repair damaged hair, it is common to use cosmetic hair compositions intended to condition the hair by providing it with satisfactory cosmetic properties. Current compositions generally aim to reduce surface defects in the hair, in particular via the deposition of compounds with a conditioning valence such as silicones, and more particularly amino silicones. The effects obtained are generally based on the use of high levels of silicones, which can, however, have the disadvantage of weighing down, or losing lightness, the hair.
[0006] Furthermore, although there are many hair repair care formulas, they generally do not provide the hair with entirely satisfactory and long-lasting cosmetic properties, particularly when the hair is very weakened, sensitized or damaged. Thus, it has been found that for the most damaged hair, the level of care may be insufficient; in particular, the smoothness (visual and to the touch) of the hair and its softness can still be improved.
[0007] Furthermore, the perception of these effects is generally only possible at the time of the application and within a few hours.
[0008] Finally, the use of high levels of silicone may be perceived unfavorably by consumers.
[0009] The invention therefore aims to propose a hair care composition which solves the problems mentioned above, and in particular will provide a high level of care and conditioning, in particular to the most damaged hair, these effects being perceptible even at low levels of amino silicone.
[0010] The present invention also aims to provide compositions which perform well in terms of cosmetic properties provided to the hair, on the one hand at the time of application and on the other hand over time.
[0011] These and other aims are achieved by the present invention which therefore has as its object a cosmetic hair care composition comprising: - at least one amino silicone of formula (I) as defined below; and - at least one polyol.
[0012] It has been found that the composition according to the invention rinses easily, which makes it possible to avoid the use of large quantities of water to remove it if necessary, for example when the composition is in the form of a shampoo or conditioner to be rinsed out.
[0013] After application, it provides a good level of care, in particular a smooth feel and appearance, softness, a homogeneous coating from root to tip and therefore repair of damaged tips, as well as a clean and natural feel, without weighing down, of the hair. The care and repair benefits are very marked while maintaining an added value of lightness and cleanliness.
[0014] Better curl definition was also observed when the composition was applied to curly hair, as well as a disciplining and controlling effect on the hair, and good volume control.
[0015] These effects of care and lightness and clean touch are significant from the moment of application and remain perceptible for at least 24 hours, or until the next shampoo. They can even persist after shampooing.
[0016] Furthermore, these cosmetic performances, in particular detangling, softness, smoothness and coating, can advantageously be obtained with a low silicone content, in particular a lower content than the content usually used.
[0017] In this description, and unless otherwise indicated: - the term “molecular weight” is equivalent to the term “molecular mass”;
[0018] - the expression “at least one” is equivalent to the expression “one or more” and can be substituted for it; - the expression “between” is equivalent to the expression “ranging from” and can be substituted for it, and implies that the limits are included.
[0019] By "cosmetic hair care composition" is meant in the context of the invention a cosmetic composition for washing (or cleaning) the hair, and / or for conditioning the hair.
[0020] In the context of the present invention, the cosmetic hair care composition is advantageously a pre-shampoo, a shampoo, a conditioner, a hair mask, a hair serum, these compositions being able to be rinsed or not rinsed after application.

[0196] The additional silicone(s) are different from the amino silicones of formula (I) as defined above.
[0197] This means that said additional silicones do not fall within the definition of formula (I), for example because they do not have an amine index and / or a molecular mass as defined for the silicones of formula (I) and / or because the meaning of at least one of their radicals R, R' and / or A is different from those indicated for the silicones of formula (I) or because they have a chemical structure different from that of the silicones of formula (I).
[0198] The additional silicone(s) may in particular be chosen from amino silicones, non-amino silicones, and mixtures thereof.

[0466] Methods for determining amine index, weight average molecular weight and viscosity A / Amine index
[0467] The amine index (or amine content) can be determined in the following manner, based on the ASTM standard Determination of Amine content (tertiary amine) of Amino alkyl silanes and siloxane fluids.
[0468] The amine number is determined by acid-base titration and is defined as the amount (in milli-equivalents or meq) of perchloric acid required to neutralize 1 g of amine in the sample.
[0469] Procedure: - weigh 10 g of sample into a 500 ml Erlenmeyer flask - add 50 ml of toluene, mix until the sample dissolves, then add 125 ml of acetic acid - while stirring, add 5 drops of crystal violet indicator (0.5% weight / volume in acetic acid, i.e. 0.5 g of crystal violet in 100 ml of acetic acid) - titrate with 0.1 N perchloric acid HC1O4 (in acetic acid) until the green color disappears; for information, the color changes occur in the following order: purple -> blue -> green -> yellow
[0470] This gives the quantity of perchloric acid necessary to neutralize the 10 g of sample.
[0471] The calculation of the amine index (AI) is done as follows: Amine index (meq / g) = [(ml HC1O4) x (N HC1O4)] / sample weight (g) In the present case (with N = 0.1 N and sample weight = 10 g), we obtain the following simplified equation: IA (meq / g) = [(ml HC1O4) x 0.1] / 10 = (ml HC1O4) / 100. B / Weight average molecular mass
[0472] The weight-average molecular mass can be determined by any known method, in particular by dynamic light scattering or by gel permeation chromatography. It is generally expressed in Daltons. C / Dynamic viscosity
[0473] The dynamic viscosity can be determined according to the following method.
[0474] Measurement conditions: 25 ± 2°C, 1 atm., relative humidity 50 ± 5%
[0475] Brookfield Viscometer: This is a precise torque meter that is driven at a discrete rotational speed. The torque measuring system, which consists of a calibrated beryllium-copper spring connecting the drive mechanism to a rotating cone, detects the rotational resistance caused by the presence of a fluid sample between the cone and a stationary flat plate. The rotational resistance of the cone produces a torque that is proportional to the shear stress in the fluid.
[0476] Sample size: 500mL in a beaker.
[0477] Needles (spindles) used, depending on the viscosity range to be measured: Spindle No. 1: for viscosities below 950 mPa.s Spindle No. 2: 950-3800 mPa.s Spindle n°3: 3800-4750 mPa.s Spindle n°4: 4750-9500 mPa.s
[0478] The viscosity measurement will begin with needle No. 1; if the viscosity is outside the range for this needle, the next one will be tried, and so on, until an absolute viscosity value is obtained. The viscosity value will be taken as the value obtained after the needle has rotated for two minutes.
[0479] The following examples serve to illustrate the invention without, however, being limiting in nature. The quantities are indicated therein, unless otherwise indicated, as a percentage by mass of active material (AM) relative to the total weight of the composition.

[0485] Hair compositions are obtained which can be used as conditioners; it is noted that the composition according to the invention makes it possible in particular to provide conditioning to the hair, in particular a smooth feel and coating.
[0486] The sensory performance provided by composition A according to the invention is evaluated on wet hair and dried hair, in comparison with that provided by comparative composition A'.
[0487] The evaluation is carried out on strands of hair sensitized by a bleaching treatment. The strands are previously cleaned with a standard shampoo (DOP CAMOMILLE) at a rate of 0.3 g / g of hair, rinsed and dried.
[0488] Then apply a shampoo to the strands (Total Repair 5 ELSEVE -L'OREAL PARIS) at a rate of 0.3 g / g of hair, knead and lather, then rinse the strands with water for 15 seconds (flow rate = 300 1 / h, water temperature 35°C).
[0489] On washed and still wet strands, apply care composition A or A', at a rate of 0.45g / g of hair; leave for 5 minutes then rinse the strands with water for 10 seconds (flow rate = 300 1 / h, temperature 35°C). The evaluation is carried out on damp hair.
[0490] Then the strands are dried using a hair dryer and the evaluation is carried out on dry hair.
[0491] The following criteria are evaluated: - on damp hair: smooth touch and coating - on dry hair: smooth feel The evaluation is carried out blindly, by 6 evaluators, who award a score ranging from 0 (no performance) to 5 (very efficient), in steps of 0.5, on the criterion tested.
[0492] Evaluation of smoothness to the touch: the evaluator takes a lock of hair at the root and slides it between the fingers along the entire length of the lock to the tips. The more uniform and homogeneous the hair is from root to tip, the fewer rough spots it has, the less it catches the fingers, the better the smoothness to the touch
[0493] Coating assessment: the assessor takes the lock of hair in his hand, starts from the root, and slides down to the tips. The more deposit you feel on the fiber, the better the coating.
[0494] We obtain the following results (average of the 6 notes):
[0495] [Tables2] A A' Wet hair Smooth to the touch 4.1 + 0.2 2.7 + 0.3 Coating 4.0 + 0 2.9 + 0.4 Dry hair Smooth to the touch 4.1 + 0.2 3.3 + 0.4
[0496] It is observed that the hair treated with the composition according to the invention exhibits significantly superior cosmetic performance compared to that treated with the comparative composition, in particular with an improved smoothness to the touch, both on wet and dry hair, as well as with a more present coating. The hair therefore appears more regular, freed from its roughness and therefore repaired.

[0510] Hair compositions are obtained which can be used as conditioners, to provide conditioning to the hair.
[0511] The compositions are tested on strands of natural Caucasian hair, 2.7 g and 27 cm in length.
[0512] First, the strands are cleaned using a standard silicone-free shampoo (DOP Camomille), at a rate of 0.4 g / g hair. The shampoo is kneaded into the strand to make it lather, before a 15-second application time, then a 10-second water rinsing step (flow rate: 300 1 / h, temperature: 35°C).
[0513] In a second step, composition C or C' to be tested is applied to damp hair at a rate of 0.4 g / g hair, before a 2-minute application time followed by a 15-second water rinse (flow rate: 300 1 / h, temperature: 35°C).
[0514] Finally, the wicks are dried for 30 minutes in an oven at 60°C.
[0515] The standard shampoo application cycle + composition C or C' + drying in an oven is repeated 4 more times.
[0516] At the end of the 5th cycle, the deposition of silicone on the hair is quantified by X-ray fluorescence spectrometry via the measurement of the mass concentration of silicon element on the hair fiber.
[0517] The quantity of silicon naturally present in untreated hair is subtracted from the measurement (i.e. silicon deposit = content measured on treated hair - content measured on untreated hair).
[0518] We obtain the following results:
