Description

[Technical Field]

[0001] The present invention relates to a skin cleansing composition. [Background technology]

[0002] In recent years, skin cleansers have been developed that use nonionic surfactants that have a mild effect on the skin, but also increase the pH of the skin cleanser to enhance the cleansing effect, and further incorporate nitrogen-containing compounds such as amine compounds and cationic polymers.

[0003] Incidentally, the scent of a skin cleanser during use is an important factor in the perceived quality. However, as described above, in systems containing nonionic surfactants, polar oils such as fragrances are easily solubilized, and therefore the scent release is easily suppressed. Furthermore, under conditions of high pH and the coexistence of nitrogen-containing compounds such as amine compounds and cationic polymers, many fragrance compounds are prone to degradation such as hydrolysis, and the base odor derived from the nitrogen-containing compounds is also likely to be generated. Therefore, if an excessive amount of fragrance is added to a skin cleanser in order to intensify the scent during use and mask the base odor due to the nitrogen-containing compounds, the scent perceived during use becomes unpleasant. For this reason, there has been a need for the development of a technology that allows a pleasant scent to be perceived during cleansing with a small amount of fragrance, even at high pH and in the presence of nitrogen-containing compounds.

[0004] Techniques for improving fragrance release in high-pH formulations have been known. For example, Patent Document 1 discloses that a liquid detergent composition containing an anionic surfactant, an amine oxide surfactant, a mono-long-chain alkyl glyceryl ether, and a fragrance composition primarily composed of a specific ester-based fragrance and a terpene-based fragrance has a good fragrance release without increasing the fragrance content. Patent Document 2 discloses a fragrance composition containing a "blooming" fragrance component that imparts a strong, long-lasting fragrance scent. Patent Document 3 discloses a detergent composition that does not have the unpleasant odor caused by nitrogen-containing components such as amines by incorporating a combination of an anionic surfactant, a solvent, and a fragrance composition containing a specific odor neutralizer. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-171008 [Patent Document 2] Special Publication No. 2004-503670 [Patent Document 3] Special Publication No. 2002-539322 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the detergent composition described in Patent Document 1 is a technology relating to a liquid detergent for dishes, households, or clothing, and has a fragrance composition that is dominated by specific ester fragrances and terpene hydrocarbon fragrances in order to make the fragrance of the liquid detergent composition both strongly perceived at the bottle opening and during washing, and the perceived fragrance has a strong impact in both quality and intensity. For this reason, it is not suitable for designing a fragrance that is perceived as being of moderate strength and pleasant when applied to the skin, as in skin cleansers. The fragrance composition described in Patent Document 2 is a fragrance composition for a liquid detergent product used for manually washing dishes and cooking utensils, and contains an anionic surfactant. It has the characteristic of excellent fragrance release in systems where the amount of nonionic surfactant is 10 times or more the amount of nonionic surfactant. However, it is not a technology that can optimize fragrance release in skin cleansers where a nonionic surfactant with excellent fragrance solubilizing power is present in excess relative to the fragrance. The fragrance composition described in Patent Document 3 is characterized by containing 30% to 100% of an odor neutralizer that can react with amines to form Schiff bases, and it cannot be used to optimize the fragrance in skin cleansers where a nonionic surfactant is present in excess relative to the fragrance.

[0007] Therefore, the present invention relates to a skin cleansing composition that contains a nonionic surfactant and a nitrogen-containing compound, has a high pH, ​​has an excellent fragrance, suppresses the base odor caused by the nitrogen-containing compound, and has a fragrance that is perceived as being of moderate strength and pleasant when applied to the skin. [Means for solving the problem]

[0008] The present inventors have discovered that the above problems can be solved by employing a combination of fragrance compounds that satisfy specific conditions as fragrance components used in the skin cleansing composition, and have thus completed the present invention.

[0009] The present invention relates to a composition comprising the following components (A), (B), (C) and (D): (A) Nonionic surfactant: 0.1% by mass or more and 30% by mass or less (B) Nitrogen-containing compounds 0.08% by mass or more and 10% by mass or less (C) Fragrance ingredients containing the following (c1) and (c2): (c1) Fragrance compounds having one hydroxyl group, neither a C=O bond nor an ester bond, and a ClogP of more than 1.5: 0.002% by mass or more and 1.5% by mass or less (c2) Fragrance compounds having one carboxylic acid ester bond, no non-phenolic hydroxyl group, and a ClogP of 2 or more: 0.0001% by mass or more and 1% by mass or less (D) contains water; The skin cleanser composition has a mass ratio (c1) / (c2) of the content of component (c1) to the content of component (c2) of 1.1 or more and 21 or less, and a pH at 25°C of 9 or more and 12.5 or less. [Effects of the Invention]

[0010] The skin cleanser composition of the present invention, despite containing a nonionic surfactant and a nitrogen-containing compound, has an excellent fragrance, the base odor caused by the nitrogen-containing compound is suppressed, and the fragrance when applied to the skin is perceived as being of moderate strength and pleasant.

[0016] Examples of hydroxyamines represented by general formula (1) include 2-amino-2-hydroxymethyl-1,3-propanediol (Tris, INCI name tromethamine), 2-amino-2-methyl-1-propanol (AMP), 2-amino-2-methyl-1,3-propanediol (AMPD), 2-amino-2-ethyl-1,3-propanediol, 2-amino-2-hydroxymethyl-1,3-propanediol, 2-amino-2-hydroxyethyl-1,3-propanediol, 4-amino-4-hydroxypropyl-1,7-heptanediol, and 2-(N-ethyl)amino-1,3-propanediol.

[0017] Cationic polymers include cationized hydroxyalkyl cellulose, quaternized dialkylaminoalkyl (meth)acrylate polymers, diallyldialkyl quaternary ammonium salt polymers, diallyldialkyl quaternary ammonium salt / acrylamide copolymers, diallyldialkyl quaternary ammonium salt / acrylamide / acrylic acid copolymers, vinylimidazolium trichloride / vinylpyrrolidone copolymers, hydroxyethyl cellulose / dimethyldiallylammonium chloride copolymers, vinylpyrrolidone / quaternized dimethylaminoethyl methacrylate copolymers, and polyvinylpyrrolidone.

[0018] The content of component (B) in the skin cleanser composition of the present invention is 0.08% by mass or more, preferably 0.1% by mass or more, more preferably 1% by mass or more, and even more preferably 2% by mass or more, from the viewpoint of obtaining a sufficient cleansing effect, and is 10% by mass or less, preferably 8% by mass or less, more preferably 5% by mass or less, and even more preferably 2% by mass or less, from the viewpoint of suppressing the base odor due to the nitrogen-containing compound.

[0019] [Ingredient (C): Fragrance ingredient] The fragrance component of component (C) contains component (c1) and component (c2). (c1) Fragrance compounds having one hydroxyl group, neither a C=O bond nor an ester bond, and a ClogP greater than 1.5 (c2) Fragrance compounds having one carboxylic acid ester bond, no non-phenolic hydroxyl group, and a ClogP of 2 or more

[0020] The reason why the skin cleansing composition of the present invention contains a nonionic surfactant as component (A) and has excellent fragrance release even under alkaline conditions of pH 9 or higher and 12.5 or lower is presumed to be as follows. The fragrance compound of component (c1) has only one hydroxyl group as a polar group, making it resistant to hydrolysis even in alkaline conditions. Meanwhile, the fragrance compound of component (c2) has a carboxylic acid ester structure, but is relatively hydrophobic (with a ClogP of 2 or greater). Therefore, it is more easily incorporated into the micellar structure formed by the nonionic surfactant than into the aqueous phase, making it less susceptible to hydrolysis even in alkaline conditions. Furthermore, because both compounds contain highly hydrophilic polar groups in their molecular structures, they tend to accumulate at the interface with water even when captured in micelles formed by the nonionic surfactant. Furthermore, because they are hydrophobic, they also easily migrate from the aqueous bulk phase to the gas phase. Therefore, by blending these compounds in a specific ratio, they are easily perceived as a fragrance, even when the amount of nonionic surfactant is high in alkaline conditions.
