Description

Title of the invention: COMPOSITION FOR THE REVITALIZATION OF KERATIN FIBERS technical field

[0001] The present invention relates to a cosmetic composition. In particular, the present invention relates to a hair revitalizing composition. The present invention also relates to a non-therapeutic process for the treatment of keratinous materials. RELATED ART

[0002] Hair is generally damaged and weakened by the action of external atmospheric agents such as light, weather conditions and / or the action of mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming and / or straightening.

[0003] There are many products for revitalizing hair. In order to meet the needs of diverse consumers, cosmetic companies wish to diversify the categories of hair oil-based products.

[0004] The selected amidoamine surfactants, including stearamidopropyl dimethylamine, brassicamidopropyl dimethylamine, and behenamidopropyl dimethylamine, are readily biodegradable and of natural origin. Amidoamines can be used as surfactants either in their nonionic form (pH greater than or equal to 7) or in their cationic form (pH less than 7). The cationic form is particularly advantageous due to its benefits for hair conditioning, such as antistatic, detangling, smoothing, and suppleness effects. Efforts have been made to formulate them in various water-based formulations, such as conditioners. However, the application of dimethylamine surfactants in their cationic form to oils can alter the transparent and homogeneous appearance of the composition.

[0005] It is highly desirable to offer the advantage of revitalizing hair by using certain products with a pleasing appearance, for example, certain products with a transparent appearance, and it is also desirable that hair conditioning products be stable over time.

[0006] Therefore, it is still necessary to develop a composition for revitalizing keratin fibers, particularly human keratin fibers, for example, hair, which has a transparent appearance and is stable over time. Summary of the invention

[0007] The object of the present invention is to formulate a transparent composition for revitalizing hair, which is stable over time.

[0008] Thus, according to a first aspect, the present invention proposes a keratin fiber revitalization composition comprising:

[0009] a) at least one cationizable surfactant selected from among the tertiary amidoamines,

[0010] b) at least one lipophilic acid and

[0011] c) at least one non-ionic lipophilic surfactant based on polyglycerol.

[0012] The inventors discovered that with the presence of lipophilic acid, the surfactant Tertiary amidoamine can be transferred in its cationic form, which is insoluble in the oil phase. With the presence of a nonionic lipophilic polyglycerol-based surfactant, the cationic form of tertiary amidoamine can dissolve in the composition, resulting in a transparent and stable solution.

[0013] According to a second aspect, the present invention provides a non-therapeutic method for revitalizing keratin fibers comprising applying the composition according to the present invention to the keratin fibers.

[0014] 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

[0127] Compositions according to inventive examples (IE) 1-2 and comparative examples (CE) 1-5 were prepared with the ingredients listed in Table 2 (the contents (were expressed as percentages by weight of ingredients relative to the total weight of each leave-in oil, unless otherwise stated):

[0129] The compositions of inventive examples 1-2 are compositions according to the present invention.

[0130] The compositions of comparative examples 1 and 4 do not include a non-ionic lipophilic surfactant based on polyglycerol.

[0131] The composition of comparative example 2 does not include a cationizable surfactant and a lipophilic acid.

[0132] The composition of comparative example 3 does not include a cationizable surfactant and a non-ionic lipophilic surfactant based on polyglycerol.

[0133] The composition of comparative example 5 does not include a cationizable surfactant.

[0134] Preparation procedure:

[0135] The compositions listed above were prepared as follows, taking as an example the composition of inventive example 1:

[0136] 1). mixture of fatty compounds (i.e. dicaprylyl ether, coco-caprylate / caprate, isopropyl isostearate, squalane, undecane (and) tridecane) and perfume to obtain a hair oil base;

[0137] 2). Addition of surfactants (i.e. stearamidopropyl dimethylamine and the polyglyceryl-6-dioleate) and acid (i.e. lactic acid) with stirring; and

[0138] 3). addition of water to the oil base to obtain the composition. Assessment :

[0139] The stability of the resulting no-rinse oils was evaluated by maintaining the no-rinse oils at -10 °C for 24 hours, at room temperature (25 °C) for 1 week, and at 45 °C for 1 week, respectively, and by visually observing the physical appearance, color, and odor of the tested no-rinse oil. If no changes in the parameters are observed at any temperature, the tested no-rinse oil can be considered stable; otherwise, it is considered unstable.

[0140] The appearance of the no-rinse oils obtained was observed with the naked eye.

[0141] The level of cosmetic performance was evaluated as follows:

[0142] 1. Wash a sample of natural hair (6 g) using a regular shampoo.

[0143] 2. Apply 0.1 g of the tested oil sample evenly by hand onto the wet hair sample and

[0144] 3. Carefully dry the hair sample with oil.

[0145] The sensory characteristic of the treated hair sample was perceived by hand and classified as "acceptable" or "unacceptable" based on the following standard:

[0146] Acceptable: perceptible improvement in sensory perception compared to the original oil base.

[0147] Not acceptable: no perceptible sensory improvement compared to the original oil base.

[0148] The results have been summarized in Table 3.

[0149] [Tables3] Appearance Stability Cosmetic Performance Level ELI Homogeneity and transparency Stable Acceptable EI.2 Homogeneity and transparency Stable Acceptable EC.1 Heterogeneity and phase separation. White precipitates appear. Unstable Not acceptable EC.2 Homogeneity and transparency Stable Not acceptable EC.3 Presence of heterogeneous droplets and water at the bottom. Unstable Not acceptable EC.4 Heterogeneity and phase separation. White precipitates appear. Unstable Not acceptable EC.5 Homogeneity and transparency Stable Not acceptable

[0150] Table 3 shows that the compositions of invention examples 1-2 are stable and transparent and can provide an acceptable level of cosmetic performance.
