Description

[Technical Field]

[0001] The present invention relates to compositions for caring for keratinous substances, preferably cosmetic compositions. The present invention also relates to cosmetic methods for treating and / or caring for keratinous substances. [Background technology]

[0002] Cinnamic acid and its derivatives, such as ferulic acid, are known to be useful in fields such as cosmetics for their antioxidant, whitening / brightening, and UV protection properties. However, cinnamic acid and its derivatives, such as ferulic acid, tend to be unstable under certain conditions. For example, ferulic acid degrades upon contact with water, losing stability and producing an unpleasant odor. Furthermore, formulations containing ferulic acid may turn yellow at high temperatures, potentially affecting consumer preference and perceived efficacy.

[0003] To prevent the degradation of ferulic acid, several prior art documents disclose anhydrous compositions containing ferulic acid.

[0004] For example, US-A-2022 / 0387278 is an anhydrous composition for caring for keratinous substances, a) Ferulic acid in an amount of 0.5% to 3.0% by mass relative to the total mass of the composition, b) At least one type of C3~C 10 Polyols and, c) At least one type of silica aerogel and An anhydrous composition containing [the specified ingredient] is disclosed.

[0005] Furthermore, WO2022 / 204951 is an anhydrous composition for caring for keratin substances, a) At least one cosmetic active ingredient that is sensitive to water and / or oxygen, b) At least one nonionic surfactant selected from polyglyceryl fatty acid esters having an HLB value of 13 or higher at a temperature of 25°C, and ethoxylated / propoxylated aliphatic alcohols, c) Dipropylene glycol and The present invention discloses an anhydrous composition that contains [a specific ingredient] and does not contain any cationic surfactants.

[0006] However, there is still a need for cosmetic compositions containing water-sensitive cosmetic active ingredients, such as ferulic acid, that can suppress the degradation of these active ingredients.

[0007] Furthermore, the formulations of environmentally friendly cosmetics are designed and developed with environmental issues in mind, and this is an important goal in efforts to address global problems. Therefore, it is essential to propose more sustainable compositions, preparation methods, and ingredients to address these environmental challenges.

[0008] In this context, it is particularly important to develop new cosmetic compositions with a better carbon footprint, such as new keratin care compositions, by promoting the use of renewable raw materials and / or materials with a good index of naturalness and / or materials of natural origin.

[0165] In one preferred embodiment, the oil is an ester oil of an amino acid derivative, particularly C6-C6 22 Selected from N-acyl amino acid esters, which may be of natural origin.

[0166] N-acyl amino acid esters are generally defined by the following formula: R'1(CO)N(R'2)CH(R'3)(CH2) n (CO)OR'4 [In the formula, - n is an integer equal to 0, 1, or 2. - R'1 is a linear or branched C5-C 21 Represents an alkyl group or alkenyl group, - R'2 represents a hydrogen atom or a C1-C3 alkyl group. - R'3 represents a group selected from the group formed by a hydrogen atom, a methyl group, an ethyl group, or a linear or branched C3 or C4 alkyl group. - R'4 is a linear or branched C1-C 10 Alkyl or C2-C 10[Represents an alkenyl group or sterol residue] It belongs to them.

[0199] [Composition] The compositions according to Examples 1 to 4 (Ex. 1 to Ex. 4) and Comparative Examples 1 to 3 (Comp. Ex. 1 to Comp. Ex. 3) were each prepared by mixing the components listed in Table 1 below. All numerical values regarding the amounts of the components are based on "mass%" of the active ingredient.

[0200] [Evaluation] (Color Stability) Each of the compositions was left at 45°C for up to 2 months. After 2 months, the color (L*, a*, b*) values of the compositions were measured using a spectrophotometer V-750. Then, the following formula:

[0201] [Number]

[0202] [where L* 1D , a* 1D , b* 1D are the L*, a*, b* values of the composition after 24 hours at room temperature, respectively, and L* 2M , a* 2M , b* 2M are the L*, a*, b* values of the composition after 2 months at 45°C, respectively] was used to evaluate the color stability by the delta E (ΔE) of the composition between 24 hours at room temperature after generation and 2 months at 45°C.

[0203] The evaluation was carried out based on the following criteria. Extremely good: ΔE < 2 Good: 2 ≤ ΔE < 5 Fair: 5 ≤ ΔE < 10 Poor: 10 ≤ ΔE < 30 Extremely poor: 30 ≤ ΔE

[0204] (crystallization) Each composition was left at 4°C for up to two months. After two months, crystallization was evaluated by visual observation of the compositions. OK: After storage at 4°C for 2 months, no crystals were observed in the composition. NG: After storage at 4°C for 2 months, at least one crystal was observed in the composition.

[0205] (Stability of active ingredients) Each composition was left at 45°C for up to two months. After two months, the percentage of ferulic acid remaining after storage at 45°C for two months was measured by HPLC and calculated as a function of the initial percentage (24 hours after formation) measured by HPLC. The stability of ferulic acid was then evaluated according to the following criteria. Excellent: Ferulic acid retention rate (%) ≥ 95 Good: 90≦ferulic acid residual rate (%)<95 Possible: 80≦ferulic acid residual rate (%)<90 Defective: Ferulic acid residual rate (%) <80

[0206] (Odor evaluation) The odor of each composition was evaluated by five panelists who scored it on a scale from 0 (no odor) to 1 (odor detected). The total scores were calculated and classified according to the following criteria. OK: Total=0 NG:1≦total≦5
