Description

Title of the invention: Cosmetic composition comprising an anionic surfactant, an amphoteric surfactant, an alpha-omega bis-amino silicone and an amino silicone

[0001] The present invention relates to a cosmetic composition comprising an anionic surfactant, an amphoteric surfactant, an alpha-omega bis-amino silicone and an additional amino silicone, with a weight ratio between the total content of alpha-omega bis-amino silicone and the total content of additional amino silicone strictly less than 1.

[0002] The invention also relates to a method for the cosmetic treatment of keratin fibers, in particular human keratin fibers such as hair, comprising at least the application of the cosmetic composition according to the present invention.

[0003] The present invention also relates to the use of said composition for washing and / or conditioning keratin fibers.

[0004] Keratin fibers, especially hair, tend to lose some of their qualities under the action of various factors such as, for example, natural regreasing, sweat, the elimination of scales, pollution or humidity. The visual appearance as well as the feel of the fibers can be degraded. For example, regreasing weighs down the fibers, which then tend to clump together. The hair can then be more difficult to style, have a greasy shine and / or an unpleasant waxy feel.

[0005] For washing keratin fibers, such as hair, the use of detergent cosmetic compositions of the shampoo type, essentially based on surfactants, is common. These compositions are generally applied to the keratin fibers, preferably wet, and the foam generated by massage or friction with the hands or a washcloth allows, after rinsing with water, the elimination of the various dirt initially present on the hair.

[0006] Repeated use of such compositions can damage keratin fibers. In particular, the hair may lose its flexibility and have a less smooth feel, and it is also more difficult to detangle.

[0007] However, consumers are looking for shampoo compositions that have good detergent power while having improved cosmetic and conditioning properties. They are also looking for shampoo compositions with an improved environmental profile while retaining very good cosmetic and conditioning properties.

[0008] It has now been discovered that a composition comprising a particular combination of amino silicones in the presence of anionic and amphoteric surfactants makes it possible to achieve the objectives set out above, in particular in terms of ease of disentangling, flexibility, smoothness to the touch, coating, softness, shine, individualization and lightness.

[0009] The present invention therefore relates to a composition comprising: (i) one or more anionic surfactants, ii) one or more amphoteric or zwitterionic surfactants, iii) one or more alpha-omega bis-amino silicones, and iv) one or more amino silicones other than silicones iii), the weight ratio between the total content of alpha-omega bis-amino silicone(s) iii) and the total content of amino silicone(s) iv) other than silicones iii) being strictly less than 1.

[0010] The particular combination of the above compounds makes it possible to obtain a composition having good detergent power while providing good cosmetic and conditioning properties to the hair with a reduced silicone content.

[0011] Indeed, the composition according to the invention makes it possible in particular to facilitate the detangling of hair, while providing a smooth and uniform feel, from root to tip; as well as a sensation of coating and treated hair.

[0012] In addition, the composition has good usage properties, in particular good rinsability.

[0013] The invention also relates to a method for the cosmetic treatment of keratin fibers, in particular human keratin fibers such as hair, comprising at least the application of the cosmetic composition according to the present invention.

[0014] Other objects, characteristics, aspects and advantages of the invention will appear even more clearly on reading the description and the example which follows.

[0015] In what follows, and unless otherwise indicated, the limits of a domain of values are included in this domain, in particular in the expressions “between” and “ranging from ... to ...”.

[0016] Furthermore, the expression “at least one” used in the present description is equivalent to the expression “one or more”.

[0017] In all that follows, silicone is used, in accordance with general acceptance, to denote all organosilicon polymers or oligomers with a linear or cyclic, branched or crosslinked structure, of variable molecular weight, obtained by polymerization and / or by polycondensation of suitably functionalized silanes, and consisting essentially of a repetition of main units in which the silicon atoms are linked together by oxygen atoms (siloxane bond -Si-O-Si-), groups optionally substituted hydrocarbons, being directly linked via a carbon atom to said silicon atoms. The most common hydrocarbon groups are alkyl groups, in particular CrCio, and in particular methyl, fluoroalkyl groups whose alkyl part is Ci-Cio, aryl groups such as in particular phenyl groups.

[0018] In a manner known per se, the viscosity of silicones, which is the kinematic viscosity, is measured at 25°C and at atmospheric pressure (1 atm, 1.013.105 Pa) according to standard ASTM 445 Appendix C.

[0019] The weight-average molecular masses of silicones can be measured by Gel Permeation Chromatography (GPC) at room temperature (25 °C) in polystyrene equivalent. The columns used are p styragel columns. The eluent is THF, the flow rate is 1 ml / min. 200 μl of a 0.5% by weight solution of silicone in THF are injected. Detection is done by refractometry and UVmetry.

[0154] [Tables 1] Composition Al (invention) Composition B1 (comparative) Sodium laureth sulfate 9.73 9.73 Cocamidopropyl betaine 0.56 0.56 Bis-Aminopropyl dimethicone 0.3 0.7 Amodimethicone 0.7 0.3 Water QsplOO QsplOO Weight ratio (Bis-Aminopropyl di-methicone / Amodimethicone) 0.4 2.3

[0155] • Ease of disentangling performance by instrumental evaluation The ease of detangling hair after application of compositions Al and B1 is assessed by instrumental cosmetic evaluation by measuring the friction forces of a previously tangled lock of hair, as it moves, at constant speed, through a metal comb. The less force is required to pass the strand through the teeth of the comb, the easier it is to detangle.

[0156] Compositions Al and B1 are applied according to the following protocol: on strands that have undergone bleaching treatment, each of the compositions Al or Bl is applied at a rate of 0.4g of composition per g of strands; it is kneaded and lathered; it is left to stand for 1 minute then the strand is rinsed with water for 15 seconds (flow rate = 3001 / h, temperature = 35°C). The friction forces of compositions Al and B1 on wet hair are measured. These measurements are expressed in rnJ. The measurement is repeated on 5 different strands.

[0157] The results are presented in the table below (averages):

[0158] [Tables2] Composition Al (invention) Composition Bl (comparative) Friction forces on wet hair (in mJ) 1191± 198 1576 + 177

[0159] Composition A1 according to the invention (having a weight ratio between the bis-aminopropyl dimethicone content and the amodimethicone content of less than 1) makes it possible to obtain a significantly better level of disentangling than composition B1 (whose weight ratio between the bis-aminopropyl dimethicone content and the amodimethicone content is greater than 1).

[0160] • Sensory cosmetic performances Three experts evaluate the sensory performance on wet and dried hair of compositions Al and B1 on strands sensitized by a bleaching treatment.

[0161] Compositions Al and B1 are applied according to the following protocol: on locks that have undergone a bleaching treatment, each of compositions Al or Bl is applied at a rate of 0.4g of composition per g of locks; the mixture is kneaded and lathered; the lock is left to stand for 1 minute and then the lock is rinsed with water for 15 seconds (flow rate = 3001 / h, temperature = 35°C). The lock is then dried with a hair dryer.

[0162] The experts evaluate the sensory cosmetic performances of the compositions Al and Bl on dried hair, on the criterion of smoothness to the touch. These ratings are rated on a scale of 0 to 5, with 0 representing the lowest rating and 5 representing the highest rating.

[0163] Evaluation of smoothness to the touch: the expert 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.

[0164] The results are presented in the table below:

[0165] [Tables3] Sensory performance (average of the 3 experts' scores) for smooth feel Composition Al (invention) Composition B1 (comparative) On dried hair Smooth feel 4 + 0.0 2.8 + 0.3

[0166] Composition A1 according to the invention (having a weight ratio between the bis-aminopropyl dimethicone content and the amodimethicone content of less than 1) makes it possible to obtain better sensory cosmetic performances, in particular in terms of smooth feel, on dry hair, than composition B1 (whose weight ratio between the bis-aminopropyl dimethicone content and the amodimethicone content is greater than 1).

[0171] [Tables5] Composition A2 (invention) Composition B2 (comparative) Friction forces on wet hair (in mJ) 1263 + 171 2125 ± 248

[0172] Composition A2 according to the invention (having a weight ratio between the bis-aminopropyl dimethicone content and the amodimethicone content of less than 1) makes it possible to obtain a significantly better level of disentangling than composition B2 (whose weight ratio between the Bis-Aminopropyl dimethicone content and the amodimethicone content is greater than 1).

[0173] Example 3 Compositions A3 (according to the invention) and B3 (comparative) were prepared from the ingredients whose contents are indicated in the tables below (% MA):

[0174] [Tableauxô] Composition A3 (invention) Composition B3 (comparative) Sodium lauryl sulfoacetate 0.97 0.97 Disodium laureth sulfosuccinate 2.5 2.5 Cocamidopropyl betaine 0.56 0.56 Bis-Aminopropyl dimethicone 0.03 0.07 Amodimethicone 0.07 0.03 Water QsplOO QsplOO Weight ratio (Bis-Aminopropyl di-methicone / Amodimethicone) 0.4 2.3

[0175] • Sensory cosmetic performances Two experts evaluate the sensory performance on damp hair of compositions A3 and B3 on strands sensitized by a bleaching treatment.

[0176] Compositions A3 and B3 are applied according to the following protocol: on locks that have undergone a bleaching treatment, each of compositions A3 or B3 is applied at a rate of 0.4g of composition per g of locks; the mixture is kneaded and lathered; the lock is left to stand for 1 minute and then the lock is rinsed with water for 15 seconds (flow rate = 3001 / h, temperature = 35°C).

[0177] The experts evaluate the sensory cosmetic performances of compositions A3 and B3 on damp hair on the criterion of smoothness to the touch. These ratings are rated on a scale of 0 to 5, with 0 representing the lowest rating and 5 representing the highest rating.
