Description

Title of the invention: Composition comprising an anti-dandruff active ingredient, an anionic carboxylate or carboxylic surfactant, and an alpha-olefmol sulfonate, with a specific weight ratio between the two surfactants

[0001] The present invention relates to a composition comprising at least one specific anti-dandruff active ingredient, at least one anionic carboxylate or carboxylic surfactant and at least one alpha-olefin-sulfonate, and wherein the anionic carboxylate or carboxylic surfactant(s) and the alpha-olefin-sulfonate(s) are present in a particular weight ratio.

[0002] The invention also relates to a cosmetic treatment process implementing this composition and to the use of said composition for the cosmetic treatment of keratinous materials. technical field

[0003] Hair is generally damaged and weakened by the action of external atmospheric agents such as light and weather, as well as by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming and / or straightening, or even repeated washing.

[0004] Hair is thus damaged by these different factors and can eventually become dry, rough, brittle or dull, especially in fragile areas, and more particularly at the ends.

[0005] Furthermore, consumers may experience problems of discomfort and / or desquamation of the scalp (also referred to as scalp in this description) leading to the appearance of dandruff.

[0006] To remedy these inconveniences, it is common to use hair care products which employ compositions designed to condition the hair by providing satisfactory cosmetic properties, including a smooth feel (softness), suppleness, manageability and good detangling properties, and which provide short-term effects to address scalp discomfort and limit the presence of dandruff.

[0007] However, existing products on the market do not necessarily provide complete satisfaction and can still be improved, particularly with regard to their cosmetic properties. Furthermore, these products do not always have a sufficiently fluid consistency suitable for curly hair. Indeed, with curly hair, the scalp is less accessible, and spreading the product evenly over the entire scalp is therefore more difficult.

[0008] There is therefore a real need to provide a composition that reduces, or even eliminates, the undesirable effects of discomfort and / or flaking of the scalp, while maintaining good cosmetic properties for the hair and roots, particularly in terms of smoothness (softness), suppleness, manageability, and detangling. Furthermore, it is important that the compositions have a sufficiently fluid consistency and good foaming properties to facilitate application to the scalp, especially for people with curly hair.

[0009] It was discovered, surprisingly, that the cosmetic compositions according to the invention made it possible to achieve the objectives set out above. Description of the invention

[0010] The present invention therefore relates to a composition comprising: a) at least one anti-dandruff active ingredient chosen from the derivatives of l-hydroxy-2-pyridone and their salts, b) at least one first anionic surfactant chosen from among the carboxylate or carboxylic anionic surfactants, c) at least one second anionic surfactant selected from alpha-olefin sulfonates, and in which the weight ratio between the total content of the alpha-olefin-sulfonate(s) c) and the total content of the anionic carboxylate or carboxylic surfactant(s) b) is greater than or equal to 1.5.

[0011] The composition according to the invention makes it possible to provide good cosmetic properties to keratin fibers, such as a smooth touch (softness), suppleness, discipline and ease of detangling.

[0012] The composition also has a sufficiently liquid galenic consistency and good foaming properties to facilitate the application of the composition to the scalp.

[0013] The composition according to the invention also makes it possible to reduce, or even eliminate, desquamation of the scalp.

[0014] The present invention also relates to a cosmetic treatment method, preferably for keratinous materials, in particular human keratinous materials such as the scalp and hair, comprising the application to said keratinous materials of the composition according to the invention.

[0211] Compositions Al, A2 and A3, as described in Table 1 below, were prepared: quantities are expressed in g of active material (% MA) unless otherwise stated.

[0212] [Tables 1] Compositions A1 (invention) A2 (invention) A3 (comparative) Salicylic acid 1 1 1 Piroctone Olamine a) 0.5 0.5 0.5 Laureth-5 carboxylic acid b) 2 2 3.5 Sodium C14-16 olefin sulfonate ec) 4.9 4.9 3.5 Glycerin 10 7 7 Hydrogenated castor oil PEG-60 0.2 0.2 0.2 PEG-55 propylene glycol oleate 0.2 0.2 0.2 Cocamidopropyl betaine 4.6 4.6 4.6 Polyquaterium-67 0.15 0.15 0.15 Niacinamide 0.5 0.5 0.5 Propylene glycol 0.2 0.2 0.2 pH adjuster Qs pH = 5.2 + / - 0.3 Qs pH = 5.2 + / - 0.3 Qs pH = 5.2 + / - 0.3 Preservative, Viscosity agent Qs Qs Qs Water Qsp 100 Qsp 100 Qsp 100 Weight Ratio c) / b) 2.45 2.45 1

[0213] Thus, compositions Al and A2 are two compositions according to the invention. They significantly reduce the undesirable effects of scalp discomfort and flaking while offering satisfactory cosmetic properties. In particular, it has been observed that these compositions provide treated hair with good cosmetic properties, notably in terms of smoothness (softness), suppleness, manageability, and detangling. Evaluation of foam rise

[0214] It has been observed that composition A2 according to the invention exhibited good foaming properties, such as foam initiation, abundance and quality.

[0215] In contrast, the foam in comparative composition A3 was less stable and broke more quickly. Evaluation of the detangling process

[0216] Five trained experts observed the effects of the compositions according to the invention and the comparative composition on dry hair. In particular, compositions A2 and A3 were applied to half-heads of malleable heads with natural hair at a rate of 6 g of composition per half-head; the half-heads were then rinsed and dried. The detangling assessment was carried out on dry hair. More specifically, the expert ran the comb from the root to the tip of the hair. The sooner the comb stopped, the more difficult the strand would be to detangle. It was observed that the hair treated with composition A2 exhibited better detangling properties than that treated with composition A3.
