Description

[Technical Field]

[0001] The present invention relates to a cleansing composition with reduced unpleasant odors. [Background technology]

[0002] In cleansing compositions, specific polyhydric alcohols or polyhydric alcohol derivatives, such as glycerin, diglycerin, sugars, and sugar alcohols, are widely used to improve moisturizing properties, usability, and stability. Polyglycerin fatty acid esters, which are polyglycerin derivatives, are also used to improve rinseability and foam elasticity. Furthermore, the use of amino acids, amino acid derivatives, or amino acid surfactants can enhance product value by improving functionality such as moisturizing properties, usability, and rinseability. However, the combination of these with specific polyhydric alcohols or polyhydric alcohol derivatives has been problematic, resulting in the generation of odor over time. To address this issue, fragrances and synthetic chemical ingredients have been used. However, fragrances have limited applications due to their strong scents, and the use of synthetic chemical ingredients raises safety concerns, so improvements have been needed. Therefore, natural extracts have attracted attention, but the problem of detergent compositions containing specific polyhydric alcohols or polyhydric alcohol derivatives and amino acids, amino acid derivatives, or amino acid surfactants often fails to provide sufficient odor reduction. A technique is known in which kojic acid is used to suppress the unpleasant odor that occurs over time when an amino acid or a derivative thereof is incorporated into an external skin preparation (Patent Document 1). It is known that a water-soluble reducing agent or a chelating agent may be added to remove the peculiar odor derived from basic amino acids (Patent Document 2). When a component having an amino group, such as an amino acid or a derivative thereof, is coexistent with a polyhydric alcohol, such as glycerin or diglycerin, there is a high probability that an unpleasant odor will be generated during high-temperature storage. However, a technology has been disclosed that uses silver to suppress the generation of this unpleasant odor (Patent Document 3). A technique for suppressing unpleasant odors using octocrylene has been disclosed for external skin preparations containing N-acylamino acid derivatives (Patent Document 4).

[Effects of the Invention]

[0006] According to the present invention, it is possible to inhibit the generation of odor over time from a cleansing composition containing a polyhydric alcohol or a polyhydric alcohol derivative and an amino acid or an amino acid derivative. DETAILED DESCRIPTION OF THE INVENTION

[0007] The cleansing composition of the present invention contains the following components (A) to (D): component (A): water; component (B): one or more selected from glycerin, diglycerin, polyglycerin, glycerin derivatives, polyglycerin derivatives, sugars, sugar derivatives, sugar alcohols, and sugar alcohol derivatives; component (C): amino acids and / or amino acid derivatives; and component (D): hydrolyzed olive leaf extract and / or rubus fruticosus root extract.

[0008] The cleanser composition of the present invention is used to remove dirt and cosmetics from skin and hair, and examples thereof include soap, skin cleanser, facial cleansing cream, cleansing cream, cleansing emulsion, cleansing liquid, cleansing oil, shampoo, etc.

[0009] The cleansing composition of the present invention contains component (A): water. The water content is preferably 0.0001% by mass or more, and preferably 60% by mass or less, more preferably 10% by mass or less, and particularly preferably 5% by mass or less.

[0010] The cleansing composition of the present invention contains component (B): glycerin, diglycerin, polyglycerin, a glycerin derivative, a polyglycerin derivative, a sugar, a sugar derivative, a sugar alcohol, or a sugar alcohol derivative. The degree of polymerization of the polyglycerin is preferably 3 to 30. Examples of the glycerin derivative include PEG / PPG / polybutylene glycol-8 / 5 / 3 glycerin, lecithin, alkyl glyceryl ether, glycerin monofatty acid ester, polyoxyethylene glycerin ether fatty acid ester, etc. Examples of the polyglycerin derivative include polyglycerin fatty acid ester, polyglycerin alkyl ether, polyglycerin-modified silicone, etc. Examples of the sugar include glucose, fructose, mannose, xylose, sucrose, maltotriose, arabinose, trehalose, etc. Examples of sugar derivatives include cellulose, starch, dextrin, dextran, inulin, glycosphingolipids, flavonoid glycosides, ascorbic acid glucoside, hyaluronic acid, cellulose gum, methylcellulose, hydroxypropyl cellulose, hydroxypropylmethylcellulose, polyquaternium-10, xanthan gum, polyoxyalkylene alkyl glucoside, and sugar fatty acid esters. Examples of sugar alcohols include sorbitol, maltitol, xylitol, and erythritol. Examples of sugar alcohol derivatives include sorbitan, sorbitan fatty acid esters, and polyoxyethylene sorbitan fatty acid esters. Component (B) is added to improve moisturizing properties, usability, stability, rinse-off function, and foam elasticity. However, when component (B) is added, the generation of an unpleasant odor over time becomes a problem when component (C) is also present. When glycerin, diglycerin, PEG / PPG / polybutylene glycol-8 / 5 / 3 glycerin, or polyglycerin fatty acid ester is added as component (B), the generation of an unpleasant odor is particularly noticeable when component (C) is also present.

[0011] The concentration of component (B) contained in the cleansing composition of the present invention is preferably from 1 to 60% by mass, more preferably from 10 to 50% by mass, and particularly preferably from 20 to 40% by mass.

[0012] The cleansing composition of the present invention contains component (C): an amino acid or amino acid derivative. Examples of amino acids include arginine, glycine, serine, glutamine, glutamic acid, asparagine, aspartic acid, tyrosine, methionine, proline, hydroxyproline, valine, histidine, threonine, leucine, isoleucine, alanine, phenylalanine, tryptophan, lysine, ornithine, cysteine, cystine, and theanine. Examples of amino acid derivatives include PPG-2 arginine, cocoyl arginine ethyl PCA, dihydroxypropyl arginine hydrochloride, alkyl (C12,14)oxyhydroxypropyl arginine hydrochloride, fatty acid acyl glutamate, fatty acid acylaspartate, fatty acid acylglycine salt, fatty acid acylalanine salt, dilauroyl glutamic acid lysine salt, oligopeptide, hydrolyzed collagen, collagen, silk, phosphatidylserine, and trimethylglycine. Component (C) is formulated to improve functionality such as moisturizing properties, usability, and rinsability, but when it coexists with component (B), it can cause the generation of an unpleasant odor over time. In particular, when arginine or an arginine derivative coexists with component (B), it is likely to cause the generation of an unpleasant odor over time. Examples of arginine derivatives include PPG-2 arginine (labeling name), cocoyl arginine ethyl PCA (labeling name), dihydroxypropyl arginine HCl (labeling name), and alkyl (C12,14) oxyhydroxypropyl arginine HCl (labeling name).

[0013] The concentration of component (C) contained in the cleansing composition of the present invention is preferably from 0.001 to 50% by mass, more preferably from 0.01 to 30% by mass, and particularly preferably from 0.01 to 10% by mass.

[0014] The cleansing composition of the present invention contains component (D): hydrolyzed olive leaf extract or rubus fruticosus root extract. Hydrolyzed olive leaf extract is obtained by hydrolyzing the extract of olive leaves (Olea europaea Linne) with acid, enzymes or other methods. Rubus ellipticus Smith root extract is an extract of the roots of Rubus ellipticus Smith. A commercially available product, Himalayan raspberry extract BG80 manufactured by Maruzen Pharmaceutical Co., Ltd., can also be used in the present invention. The cleanser composition of the present invention can suppress the generation of unpleasant odors over time by incorporating component (D). The concentration of component (D) incorporated into the cleanser composition of the present invention is preferably 0.0001% by mass or more and 0.1% by mass or less.

[0015] In addition to the components (A) to (D), the cleanser composition of the present invention may contain oils, surfactants, polyhydric alcohols, water-soluble polymers, oil-soluble polymers, organic powders, inorganic powders, moisturizers, fragrances, preservatives, pH adjusters, colorants, antioxidants, and the like that are typically incorporated into cleanser compositions. [Example]

[0016] <Reference exam> The generation of unpleasant odors over time was confirmed when PPG-2 arginine was allowed to coexist with glycerin and diglycerin. PPG-2 arginine, glycerin, and diglycerin were blended according to the composition shown in Table 1, and the off-odor (burnt off-odor) was evaluated after storage at 50°C for one month. Lactic acid was blended so that the pH of the composition was approximately neutral. Reference Example 1, which contained only PPG-2 arginine, was used as the standard, and the off-odor of Reference Example 2, which contained PPG-2 arginine and glycerin, and Reference Example 3, which contained PPG-2 arginine and diglycerin, was evaluated by five expert panelists according to the following criteria. 4 points: No strange odor (burnt smell) is detected compared to Reference Example 1. 3 points: Compared to Reference Example 1, there is almost no unpleasant odor (burnt odor). 2 points: Compared to Reference Example 1, there is a slight strange odor (burnt smell). 1 point: A strange odor (burnt smell) is felt compared to Reference Example 1 The following evaluation was made based on the average score. ◎: 3.6 points or more 〇: 2.6 points or more and 3.4 points or less △: 1.6 points or more and 2.4 points or less ×: 1.4 points or less

[0017] [Table 1]

[0018] As shown in Table 1, the amino acid derivative (PPG-2 arginine) alone was used as the standard, and the combination of the amino acid derivative and glycerin (Reference Example 2) and the combination of the amino acid derivative and diglycerin (Reference Example 3) were evaluated. As a result, an unpleasant odor (burnt smell) was observed after storage at 50°C for one month.

[0019] <Test to confirm odor suppression effect> The odor-suppressing effect of a cleansing composition (cleansing oil) containing component (B): glycerin, diglycerin, polyglycerin, glycerin derivative, polyglycerin derivative, sugar, sugar derivative, sugar alcohol or sugar alcohol derivative, and component (C): amino acid or amino acid derivative was evaluated. Cleansing oils were prepared with the compositions shown in Tables 2 to 4, and five expert panelists evaluated the odor of Examples 1 to 4, Reference Example 5, and Comparative Examples 1 to 19 after storage at 50°C for one month, using Reference Example 4, which does not contain (ingredient C), as the standard, according to the following criteria. 4 points: No strange odor (burnt smell) is detected compared to Reference Example 4. 3 points: Compared to Reference Example 4, there is almost no unpleasant odor (burnt odor). 2 points: Compared to Reference Example 4, there is a slight strange odor (burnt odor). 1 point: Compared to Reference Example 4, there is an unpleasant odor (burnt smell). The following evaluation was made based on the average score. ◎: 3.6 points or more 〇: 2.6 points or more and 3.4 points or less △: 1.6 points or more and 2.4 points or less ×: 1.4 points or less

[0020] [Table 2]

[0021] [Table 3]

[0022] [Table 4]

[0023] As shown in Tables 2 to 4, with Reference Example 4, which did not contain component (C): amino acid derivative, as the standard, Examples 1 to 4, which combined component (C): amino acid derivative with component (B) and further contained component (D), had no or almost no unpleasant odor (burnt odor) after storage for 1 month at 50°C. On the other hand, Comparative Examples 1 and 2, which did not contain component (D), and Comparative Examples 4 to 19, which contained citric acid, rosemary leaf extract, 3-O-ethyl ascorbic acid, glucosyl rutin, hydrolyzed conchiolin protein, soybean sprout extract, sodium citrate, sodium tocopheryl phosphate, potassium ascorbyl / tocopheryl phosphate, menthol, lavender flower extract, evening primrose seed extract, peony extract, tallow fruit extract, tea leaf extract, plum fruit extract, or barberry fruit extract instead of component (D), had an unpleasant odor (burnt odor). Comparative Example 3, which contained olive leaf extract instead of component (D), had a slight unpleasant odor (burnt smell). Reference Example 5, which did not contain component (B), had no unpleasant odor (burnt smell). This cleansing oil from Reference Example 5 emulsifies components (A) and (C) by adding PEG-30 dipolyhydroxystearate instead of component (B), which would cause components (A) and (C) to separate if component (B) polyglyceryl-10 diisostearate, polyglyceryl-20 hexacaprylate, and polyglyceryl-20 octaisononanoate were removed.
