Description

Title of the invention: HAIR REVITALIZING COMPOSITION technical field

[0001] The present invention relates to the field of cosmetics. In particular, the present invention relates to a composition, preferably for revitalizing hair. The present invention also relates to a hair revitalization process. PRIOR TECHNOLOGY

[0002] Consumers tend to use leave-in scalp lotions when they have noticed their scalp problem: dandruff, scalp sensitivity, hair loss, etc.

[0003] Some leave-in products generally contain a high concentration of hydroalcoholic soluble active ingredients. To achieve greater transdermal absorption or penetration through the follicles, a simple method is to ensure a concentration gradient, meaning that a large amount of the active ingredient remains on the surface. Generally, a large amount of active ingredient will cause a sticky feeling on the scalp and at the hair roots, which is undesirable for consumers.

[0004] We therefore wish to have an effective solution for good sensory quality of hair. Summary of the invention

[0005] An object of the present invention is therefore to develop a composition, preferably for hair revitalization, which can offer a good fiber sensory quality.

[0006] Thus, according to a first aspect, the present invention proposes a composition, preferably for hair revitalization, comprising:

[0007] a) at least one cellulose-based polymer;

[0008] b) at least one non-ionic surfactant;

[0009] c) from 1.5% by weight to 30% by weight of at least one hydroxyl acid, relative to the total weight of the composition; and

[0010] d) at least one carboxylic acid of formula (I) and / or a salt thereof:

[0011] Ri-N-(CH(R2)COOH)2 (I)

[0012] in which:

[0013] - Ri represents a hydrogen atom or a group -CH(COOH)-(CH2)2-COOH,-CH 2CH2OH, -CH(CH3)COOH, -(CH2)2N(COR3)-CH2-COOH or -CH(COOH)-CH2 -COOH; And

[0014] - R2 represents a CH2COOH group when Ri represents a hydrogen atom or R2 represents a hydrogen atom when Ri is other than a hydrogen atom; and

[0015] - R3 represents a linear or branched alkyl group comprising 1 to 4 atoms of carbon or a cyclic alkyl group comprising 3 to 30 carbon atoms.

[0016] The inventors have discovered that the composition according to the present invention can effectively offer a good fiber sensory quality including softness and / or a non-greasy and / or not too sticky feeling.

[0017] According to a second aspect, the present invention proposes a hair revitalization process comprising the application of the composition according to the present invention to the hair.

[0018] Other subjects and features, aspects and advantages of the present invention will become even clearer upon reading the detailed description and examples that follow. DETAILED DESCRIPTION OF THE INVENTION

[0124] 1). Addition of water into a main container;

[0125] 2). Addition of hydroxyethylcellulose under stirring until the powder hydroxyethylcellulose should be well wetted and dispersed;

[0127] 4). addition of lactic acid and water-soluble active ingredients (glycyrrhizate of dipotassium, niacinamide and caffeine) with stirring to obtain a homogeneous composition; and

[0128] 5). pH correction with potassium hydroxide. Assessment

[0129] The stickiness of the fiber, the feeling of softness and the oily hair after application of the compositions of inventive examples 1 to 3 and comparative examples 1 to 6 were evaluated by an in vitro strand test. In vitro wick test

[0130] Strands of 1 g of natural hair were fixed upside down to a support via the root using a fixing clip. 0.45 g of the test compositions was applied to the fiber 3 cm from the root.

[0131] The sticky feeling was rated from 1 to 5 by a hair expert according to the following criterion:

[0132] 1: no sensation of a powdery coating, no sticky sensation on the fingers after touching the strands;

[0133] 2: slightly powdery coating, slightly sticky feeling on the fingers, but the wick is smooth;

[0134] 3: powdery coating and sticky feeling on the fingers, acceptable and will not be not related to a feeling of dirtiness;

[0135] 4: significant powdery coating and sticky feeling on the fingers, the re garment gives a poor impression of dirtiness, still no visible white powder on the strands;

[0136] 5: highly powdery and very sticky coating on the fingers, and powder Visible white hair may appear after several combings.

[0137] The stickiness notes of the fibre after application of the compositions of inventive examples 1 to 3 and comparative examples 1 to 6 have been summarized in Table 3.

[0139] In a single-center, randomized, double-blind study, 69 European women were asked to use the composition of inventive example 1 for 8 weeks and to complete a questionnaire on the feeling of softness to the touch and the absence of a greasy feeling of the hair immediately after the first application (Timm) and after 8 weeks of application (Tw8). The percentages of women who agreed with the statements were recorded.

[0140] The results after application of the composition of inventive example 1 have been summarized in Table 4.

[0141] [Tables4] Timm Tw8 Time Point: Leaves hair soft to the touch 43% 78% Does not leave hair greasy 68% 70%

[0142] It can be seen in Table 4 that the composition of inventive example 1 results in a feeling of softness of the hair and does not leave the hair greasy.
