Description

[0001] WASHING AND FOAMING COMPOSITION FOR KERATIN FIBRES, COMPRISING AT LEAST ONE GLUCAMIDE, AT LEAST ONE PARTICULAR ANIONIC SURFACTANT AND AT LEAST ONE PARTICULAR CATIONIC SURFACTANT The present invention relates to a cosmetic composition, notably a hair composition, in particular a foaming composition, for washing keratin materials, comprising at least one particular anionic surfactant, at least one glucamide compound and at least one cationic surfactant chosen from fatty amidoamines. The invention also relates to a process for the cosmetic treatment of keratin materials, notably keratin fibres, comprising the application of the composition according to the invention to said keratin materials. It is common practice to use detergent compositions (such as shampoos) based essentially on surfactants, for cleansing and / or washing keratin fibres such as the hair. These compositions are applied to wet hair and the foam generated by massaging or rubbing with the hands makes it possible, after rinsing with water, to remove the various types of dirt initially present on the hair or the skin. In addition, it is known practice to propose shampoos, notably for hair that is sensitized or embrittled to various degrees following the action of atmospheric agents or repeated mechanical or chemical treatments, containing conditioning agents such as silicones, in order to confer conditioning properties on the keratin fibres, for example a better feel, greater suppleness or easy disentangling. However, these washing compositions based on anionic surfactants, generally of sulfate type, and on silicones, have several drawbacks. Notably, the initiation of foaming, the amount of foam generated and more particularly the quality and texture of the foam are deemed to be insufficient. In addition, repeated applications of these silicone-based compositions often have the effect of giving the hair an unpleasant feel (hair gets greasy again very quickly), loss of volume (lank hair) and bounce of the head of hair, and occasionally lack of sheen. Moreover, the formulation of environmentally friendly cosmetic products, i.e., products designed and developed while taking account of environmental issues, is becoming a major concern in helping to meet global challenges. It is thus proving essential to propose more sustainable compositions, thereby making it possible to tackle these environmental issues. In this context, it is important to develop novel cosmetic compositions with a better carbon footprint, notably by promoting the use of starting materials that are renewable and / or that have a good naturalness index and / or that are of natural origin and more particularly of plant origin, while reducing the use of compounds of petrochemical origin. Hence the interest in developing a composition which is intended for the treatment of keratin fibres, which is advantageously free of anionic surfactants of sulfate type (sulfate-free), which has good cosmetic properties and improved working qualities, and which is capable of washing keratin fibres without making them lank, so as to give the keratin fibres good conditioning properties. There is therefore a real need to develop compositions which are more environmentally friendly, and preferably sulfate-free, which make it possible to obtain excellent washing and working properties, in particular in terms of the initiation of foaming, quality and amount of foam generated, and more particularly the texture of the foam, notably producing a creamy foam. It is also advantageous for these compositions to confer good conditioning properties on the keratin fibres, in particular in terms of suppleness, smoothness to the touch, disentangling and coating of the keratin fibres. These aims are achieved with the present invention, one subject of which is notably a composition, preferably a cosmetic composition, comprising: (i) at least one anionic surfactant chosen from alpha-olefin sulfonates, (ii) at least one glucamide compound, and (iii) at least one cationic surfactant chosen from fatty amidoamines comprising at least one C6-C30 hydrocarbon chain. The composition according to the invention has been found to have excellent keratin fibre-washing power. In particular, the hair treated with the composition according to the invention is particularly clean and has good cosmetic properties. It makes it possible to remove dirt effectively and obtain a clean visual effect of the keratin fibres. It has also been noted that the hair thus treated is particularly light, soft to the touch, smooth to the touch, supple, easy to disentangle and more manageable. The composition according to the invention coats the hair without however making it lank. In addition, it has been observed that the composition according to the invention has good working qualities, notably good initiation of foaming and good foam quality and amount. It has very particularly been noted that the composition according to the invention makes it possible to generate a large amount of foam. The foam generated by the composition according to the invention is rich, creamy, firm and abundant, which is particularly appreciated by users. A subject of the invention is also a process for treating, in particular cosmetically treating, keratin materials, notably keratin fibres, in particular human keratin fibres such as the hair, comprising at least one step of applying a composition according to the invention to said keratin materials.

A sensory evaluation of the hair treated with compositions A and B was carried out. Compositions A and B were respectively applied to locks of moderately sensitized (SA20) Caucasian hair weighing 5.4 g, in a ratio of 0.28 gram of composition / gram of hair. The locks of hair were then massaged, and then rinsed with water. A sensory evaluation of the conditioning properties of each treated lock when wet was carried out blind by 3 experts. For this purpose, each expert compared, blind, the lock treated with comparative composition B with the lock of hair treated with composition A according to the invention. Each expert then graded the lock of hair treated / washed using comparative composition B, according to the following scores: +1: significantly better than composition A according to the invention, +0.5: slightly better than composition A according to the invention, 0: similar to the lock treated with composition A according to the invention, -0.5: slightly poorer than composition A according to the invention, -1: significantly poorer than composition A according to the invention. The lock treated with composition A according to the invention was given the score 0. Evaluation of suppleness: Definition: The lock of hair bends with no resistance, it is not stiff. Handling: the expert holds the lock in one hand. With the other hand, they bend the lock of hair twice in the palm and crush the lock 3 times in order to evaluate the resistance of the hair, opening the hand between each pressure. Evaluation of coating: Definition: Sensation of product remaining on the lock of hair (presence of a residual film). Handling: the expert holds the lock in one hand; they place the thumb of the other hand on the front of the lock and the index and middle fingers on the back. They slide these three fingers over the lock from root to tip, 3 times. The results are collated in the table below. [Table 2] A B Suppleness (Inv.) (Comp.)

Expert 1 0 -2 Expert 2 0 -1 Expert 3 0 0 Mean 0 -1 Standard - 1 deviation Hair treated with composition A according to the invention was found to be significantly more supple and more comprehensively coated than hair treated with comparative composition B. Moreover, it was observed that hair washed with composition A according to the invention is particularly clean, easy to disentangle and soft to the touch. Composition A according to the invention rapidly generates an abundant foam of good quality with a pleasant (creamy) texture. Example 2: Disentangling of hair treated with compositions A or B of Example 1 was measured by machine. This machine measurement of disentangling of the hair makes it possible to measure the work done by the force of friction (in mJ) of a lock of hair previously entangled in a standardized manner, as it moves, at constant speed, through a metal comb, using an extensometer. The lower the force required to pass the lock through the teeth of the comb, the easier the disentangling. Protocol: Compositions A and B were each applied to 6 locks of hair weighing 2.7 g and 27 cm long, sensitized (SA20), of Caucasian origin, i.e. 6 locks treated with composition A and a further 6 locks treated with composition B. The locks were then immersed in water, following the steps below: 1. Before starting the measurements, prepare a thermostatically controlled water bath filled with demineralized water at 37°C, having previously placed inside two 500 ml stainless steel beakers filled with demineralized water up to the rim. 2. Adjust the level of the water bath. 3. Attach a lock on the rim of a beaker. 4. Let the lock sit immersed in the water for 5 minutes. The locks are then disentangled and entangled in a standardized manner. The measurements are carried out using a tensile-compression testing machine LS1EK or LR5K from Lloyd Instruments (France) or equivalent: 50 N force sensor from Lloyd Instruments PC-type computer controlled with NEXYGEN Plus + or equivalent software Speed of elongation: 100 mm / min 1 measurement per lock, 6 locks per composition The results are collated in the table below. [Table 4] A B Disentangling (Inv.) (Comp.) Mean 295 mJ 693 mJ Standard 93 mJ 98 mJ deviation The hair treated with composition A according to the invention was thus found to have a lower friction force value, and therefore better disentangling, than the hair treated with comparative composition B. Example 3: Composition C according to the invention and comparative compositions D, E and F were prepared from the ingredients indicated in the table below, the amounts of which are expressed as weight percentages of active material (AM).

The locks of hair were then massaged, left to rest for 5 minutes and then rinsed with water. A sensory evaluation of the conditioning properties of each treated lock when wet was carried out blind by 6 experts. For this purpose, each expert compared, blind, one of the locks treated with comparative composition D, E or F, with the lock of hair treated with composition C according to the invention. Each expert then evaluated the treated / washed hair locks using one of the comparative compositions D, E or F, assigning a score between -3 (much poorer than composition C according to the invention) and +3 (much better than composition C according to the invention) in increments of 0.5. The lock treated with composition C according to the invention was given the score 0. Evaluation of disentangling: Definition: ease of detangling wet hair after application. Handling: The expert hangs the lock of hair on a rack, then uses a wide- toothed comb (a different comb is used for each composition) to detangle the hair and assesses the difference in how easy it is to detangle. Evaluation of cosmetic properties during water rinsing: Definition: suppleness, ease of running fingers through the lock, smoothness remaining on the lock when rinsed under water. Handling: The expert holds the lock of hair by the roots with one hand.
