Description

[Technical Field]

[0001] The present invention relates to a two-part composition, preferably a two-part cosmetic composition, comprising at least one water-sensitive cosmetic active ingredient. [Background technology]

[0002] Cinnamic acids, such as ferulic acid, and their derivatives are known to be useful in fields such as cosmetics due to their antioxidant, whitening / brightening, and UV protection properties. However, cinnamic acids, such as ferulic acid, and their derivatives tend to be unstable under certain conditions. For example, ferulic acid decomposes upon contact with water, resulting in loss of stability and an unpleasant odor. To prevent the decomposition of ferulic acid, several prior art documents disclose anhydrous compositions containing ferulic acid.

[0003] For example, US-A-2022 / 0387278 is an anhydrous composition for caring for keratinic substances, a) 0.5% to 3.0% by mass of ferulic acid relative to the total mass of the composition, b) at least one C3 to C 10 Polyols, and c) Disclosed is an anhydrous composition comprising at least one silica aerogel.

[0004] Furthermore, JP-A-2024-513201 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 with an HLB value of 13 or higher at a temperature of 25°C and ethoxylated / propoxylated aliphatic alcohols, and c) Dipropylene glycol The present invention discloses an anhydrous composition that contains [a certain substance] and does not contain any cationic surfactants.

[0005] However, there is still a need for cosmetic compositions containing water-sensitive cosmetic active ingredients, such as ferulic acid, that can provide improved cosmetic effects, such as a uniform application finish and good coverage, without causing problems with the breakdown of the active ingredients.

[0006] Furthermore, the formulation of environmentally friendly cosmetics, designed and developed with environmental issues in mind, is becoming a primary goal in addressing global challenges. Therefore, it is essential to propose more sustainable compositions, preparation methods, and ingredients to address these environmental problems.

[0007] In this context, it is important to develop novel cosmetic compositions, such as novel keratin care compositions, that have a better carbon footprint, particularly by promoting the use of renewable raw materials and / or materials with a good index of naturalness and / or materials of natural origin.

[Modes for carrying out the invention]

[0028] As a result of diligent research, the inventors have discovered that a two-part composition comprising a first composition containing (a) at least one water-sensitive cosmetic active ingredient and (b) at least one polyol, and a second composition in the form of a W / O emulsion containing (c) at least one organic spherical filler and (d) at least one surface-treated pigment, can provide improved cosmetic effects such as a uniform application finish and good coverage without causing problems with the degradation of the active ingredient.

[0030] The two-part composition according to the present invention can impart improved coverage and uniformity of application to keratinous substances. Furthermore, the two-part composition can suppress (a) the decomposition of cosmetic active ingredients, and therefore (a) suppress off-odors caused by the decomposition of cosmetic active ingredients. For this reason, the composition according to the present invention is very suitable as a cosmetic composition for keratinous substances, particularly a topical cosmetic composition, because it can effectively deliver cosmetic active ingredients to keratinous substances.

[0031] The compositions and methods according to the present invention will be described in more detail below.

[0164] 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 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.

[0200] Among the starches that can be used, for example, are polymers in the form of polymers containing base units, which are anhydrous glucose units. The number of these units and their assemblies make it possible to distinguish between amylose (linear polymer) and amylopectin (branched polymer). The relative ratio of amylose to amylopectin, as well as their degree of polymerization, can vary depending on the plant origin of the starch.

[0201] The plant origin of the starch molecules that may be used in the present invention may be cereals or tubers. Therefore, the starch can be selected from, for example, corn starch, rice starch, cassava starch, barley starch, potato starch, wheat starch, sorghum starch, and pea starch.

[0202] Starches can be chemically or physically modified, in particular, by one or more of the following reactions: gelatinization, oxidation, crosslinking, esterification, etherification, amidation, and heat treatment.

[0225] The "roundness" of each particle is given by the following formula: C = 4πS / L 2 (In the formula, C represents the roundness, S represents the area (projected area) of the particle in the image, and L represents the length of the perimeter (outer edge) of the particle in the image.) This value is determined by [the following factor]. As the average roundness approaches 1, the shape of each particle becomes more spherical.
