Description

The present invention relates to a cleansing composition for skin, and in particular, it has excellent cleansing performance for cosmetics containing a large amount of oil such as makeup, and also has excellent moisturizing feeling for the skin after towel-drying. To provide a cleansing composition for skin which has good foam quality, less irritation to the skin and good washability.

A higher fatty acid salt is often used as a main cleansing component in order to use the cleansing composition for skin comfortably. Skin cleansing compositions using higher fatty acid salts have good foaming and foam quality, so the foam acts as a cushion during cleansing, allowing the skin to be washed gently, or to be washed off with a refreshing feeling. There are advantages such as preventing
On the other hand, it is known that the accumulation of sebum, skin stains, makeup using pigments, sunscreens, body paints and other oily residues on the skin leads to skin damage such as rough skin. It is very important to impart cleansing performance to skin cleansing compositions using higher fatty acid salts.

For skin cleansing compositions, polyhydric alcohols, nonionic surfactants and the like have been blended in order to obtain excellent cleansing performance. However, these methods tend to impair moisturizing feeling in exchange for obtaining excellent cleansing performance. Patent Document 1 describes a composition having excellent cleansing performance containing an amphoteric surfactant, an anionic surfactant, a mono-fatty acid glycerin ester having an acyl group having 9 to 18 carbon atoms, and a polyhydric alcohol. . However, there is a problem that the moisturizing feeling of the skin after drying with a towel is insufficient, and a feeling of dryness and tightness tends to be felt. In general, there is a trade-off between cleansing performance and moisturizing sensation, and when cleansing performance is sought, the degreasing power against sebum increases and leads to dryness of the skin, so it is very important to achieve both.

In addition, skin cleansing compositions have been blended with oils in order to obtain excellent cleansing performance. However, this method tends to impair foaming and foam quality. Patent Documents 2 and 3 describe a cleaning composition containing terpenes and mainly composed of a higher fatty acid salt that has excellent detergency against oil stains, but the foaming and foam quality are insufficient. rice field. While highly hydrophobic ingredients such as oils enhance cleansing performance, they tend to impair foaming and foam quality due to their foam-breaking effect, so it is very important to achieve both.

On the other hand, skin cleansing compositions mainly composed of higher fatty acid salts have the problem that, due to their high degreasing power, dryness and tightness are likely to be felt after cleansing. Therefore, sugar alcohols, water-soluble polymers, cationic polymers, etc. have been blended for the purpose of imparting a moisturizing feeling. Patent Document 4 discloses a detergent composition comprising a combination of dimethylammonium chloride copolymer-acrylic acid-acrylamide, algecolloid, and sodium hyaluronate. However, the ingredients added for the purpose of imparting a moisturizing feeling are water-soluble and are washed away with water during rinsing after washing, so it is difficult to improve the moisturizing feeling. There was a problem that there was a shortage of

Further, for the purpose of improving the moisturizing feeling of a skin cleansing composition mainly composed of a higher fatty acid salt, Patent Document 5 discloses that, in addition to the higher fatty acid salt, a specific cationic polymer, phenoxyethanol and polyhydric alcohol are added to improve the moisturizing effect. Disclosed is a liquid skin cleanser composition with excellent feel. However, while phenoxyethanol is highly blended for the purpose of improving moisturizing feeling, high blending of phenoxyethanol, which is generally used as a preservative, may cause irritation to the skin and eyes. There were safety concerns. Furthermore, Patent Document 5 has an effect of improving moisturizing feeling, but has no effect of improving cleansing performance.

Further, for the purpose of improving the moisturizing feeling of a detergent composition mainly containing a higher fatty acid salt, Patent Document 6 discloses that in addition to a higher fatty acid salt, a specific cationic polymer, an amphoteric surfactant, and an alkyl group having 16 carbon atoms are added. Disclosed is a liquid skin cleanser composition containing a mono-fatty acid glyceryl ether having a molecular weight of ∼18 and having excellent moisturizing sensation. However, mono-fatty acid glyceryl ethers having an alkyl group with 16 to 18 carbon atoms have the problem of markedly deteriorating foaming and foam quality due to their high hydrophobicity.

For the above reasons, while having excellent cleansing performance for cosmetics containing a lot of oil such as makeup, it has excellent moisturizing feeling after drying the skin with a towel, has good foaming and foam quality, and is less irritating to the skin. It is desired to provide a cleansing composition for skin that is easy to wash off.

JP 2007-320884 A Japanese Patent Application Laid-Open No. 2006-182698 Japanese Patent Application Laid-Open No. 2001-247449 JP-A-2002-12538 JP 2017-214327 A JP 2018-52924 A

The present invention has been made in view of the above-mentioned prior art, and has excellent cleansing performance for cosmetics containing a large amount of oil such as makeup, while having excellent moisturizing feeling of the skin after drying with a towel and lathering. To provide a cleansing composition for skin which has good foam quality, little stimulation to the skin, and good washability.

In order to achieve the above objects, the present inventors conducted intensive research, and as a result, found that a skin cleansing composition can be obtained by blending the components (A) to (C). Completed.

The first invention is
(A) Higher fatty acid salt having 8 to 22 carbon atoms in fatty acid (B) At least one cationic polymer selected from dimethyldiallylammonium chloride polymer and dimethyldiallylammonium chloride-acrylic acid copolymer (C ) At least one selected from linear mono-fatty acid glycerin esters or mono-alkyl glyceryl ethers, mono-fatty acid propylene glycol esters or mono-alkyl propylene glycol ethers, wherein the acyl group or alkyl group has 8 to 12 carbon atoms and is linear When the above is contained and a dimethyldiallylammonium chloride-acrylic acid copolymer is selected as the component (B), the molar ratio of structural units derived from dimethyldiallylammonium chloride is dimethyldiallylammonium chloride-acrylic acid copolymer The skin cleanser composition is characterized by containing 65 mol % or more of

A second invention is the skin cleanser composition according to claim 1, further comprising (D) an amphoteric surfactant.

A third invention is the skin cleanser composition according to claim 1 or 2, wherein the content of (B) is 0.1% by mass to 3% by mass.

A fourth invention is the skin cleanser composition according to any one of claims 1 to 3, wherein the content of (C) is 0.5% by mass to 15% by mass.

The skin cleansing composition of the present invention has excellent cleansing performance against cosmetics containing a large amount of oil, such as makeup, while providing an excellent moisturizing effect on the skin after towel-drying. It is less irritating to the skin and easy to wash off.

The present invention will be described in more detail below. In addition, unless there is a special comment, when displaying the compounding quantity of a component below with "%", it means the mass %. In addition, the blending amounts below indicate the pure content of the ingredients.

The present invention applies coacervation, which is a technique generally used to improve the feeling of use (conditioning effect) of shampoo, to cleansing agents for the skin. Coacervation occurs when the cationic polymer is solubilized by an anionic surfactant or amphoteric surfactant and is diluted to reduce the concentration of the surfactant. It is a phenomenon that forms a complex of This complex is called a coacervate, and since coacervate is insoluble in water, it easily remains on the hair and skin, and can impart moisturizing and smooth feel.

In the present invention, by coexisting the components (A) to (C), the coacervate formed when the skin cleanser composition is diluted with water is reduced compared to the case where the components (A) to (B) are used alone. We found that the amount increased. Until now, it was not known that coacervates improve the cleansing effect of cleansing agents. The effect of improving both the performance and the moisturizing feeling of the skin after towel-drying was realized.

As the higher fatty acid salt (A) used in the present invention, those commonly used in cosmetics can be used, and are blended for good foaming, foam quality and washability. Examples of fatty acids include, but are not limited to, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, oleic acid, linoleic acid, and coconut oil fatty acid. Alkali metals such as sodium and potassium; alkaline earth metals such as calcium and magnesium; ammonium (NH ₄ ⁺ ); organic ammonium; and basic amino acids such as L-arginine. Among these, the alkali metals sodium and potassium are particularly preferred.

The amount of component (A) to be blended is not particularly limited as long as the effects of the present invention can be obtained, but it is usually 1 to 50% by mass, preferably 10 to 40% by mass, based on the total amount of the skin cleanser composition. Used in the range of %. Within this range, the foamability of the skin cleanser composition is very excellent.

Component (A) may be used alone or in combination.

The cationic polymer (B) used in the present invention has the property of forming a complex with a higher fatty acid salt and forming a coacervate when diluted with water. Improve moisturizing. At least one or more selected from dimethyldiallylammonium chloride polymer and dimethyldiallylammonium chloride-acrylic acid copolymer,

ただし、前記一般式（１）中、ｎ、及びｍは各構造単位のモル比率（モル％）を示し、ｎ＋ｍ＝１００であり、前記ｍは６５モル％以上である。 The dimethyldiallylammonium chloride-acrylic acid copolymer of the component (B) is represented by the following general formula (1).

However, in said general formula (1), n and m show the molar ratio (mol%) of each structural unit, n+m=100, and said m is 65 mol% or more.

The molar ratio of structural units derived from dimethyldiallylammonium chloride in the dimethyldiallylammonium chloride-acrylic acid copolymer of the component (B) is 65 mol% or more from the viewpoint of moisturizing the skin after drying with a towel. Yes, preferably 95 mol % or more. If the molar ratio is less than 65 mol%, it becomes difficult to form a complex (coacervate) with the higher fatty acid salt, and the moisturizing sensation of the skin after drying with a towel may be insufficient.

The molar ratio of the structural units in the dimethyldiallylammonium chloride-acrylic acid copolymer of the component (B) can be determined by nuclear magnetic resonance (NMR) measurement under the following measurement conditions.

The acyl group or alkyl group of component (C) has 8 to 12 carbon atoms and is linear. Those having a branched structure in the acyl group or alkyl group cannot increase the amount of coacervate formed. Furthermore, when the number of carbon atoms in the acyl group or alkyl group is more than 12, the skin cleanser composition foams and the foam quality is significantly deteriorated. On the other hand, when the number of carbon atoms in the acyl group or alkyl group is less than 8, the amount of coacervate formed cannot be increased.

The amount of component (C) is not particularly limited, but is preferably 0.5% to 15% by mass, more preferably 1% to 5% by mass. Within this range, the coacervate formed by the components (A) to (C) improves both the cleansing performance for cosmetics containing a large amount of oil, such as make-up, and the moisturizing sensation of the skin after towel-drying.

Component (C) may be used alone or in combination thereof.

The amphoteric surfactant (D) used in the present invention has at least one cationic functional group and one anionic functional group. It has properties similar to nonionic surfactants.

[Evaluation of coacervate production]
Since coacervate produces turbidity in proportion to the amount of coacervate produced, the amount of coacervate produced can be evaluated based on the absorbance.
It is generally known that when a consumer lathers a facial cleansing foam, the facial cleansing foam is soaked with 7 times the amount of water and foamed. Therefore, in this evaluation, each of the skin cleanser compositions of Examples and Comparative Examples was diluted 8-fold with purified water, and then transferred to a 96-well plate (TrueLine culture plate, TR5003, culture area 0.32 cm2/1 well). 200 μL was added, and the absorbance at 540 nm was measured using a microplate reader (TECAN, infinite F200 PRO).

(B) component and (B') component

Examples 1-15 and Comparative Examples 1-8 are transparent liquids. From Examples 1 to 15, when the skin cleanser composition containing the components (A) to (C) at the same time was diluted 8 times, the solution became cloudy and showed absorption at a wavelength of 540 nm, indicating that a coacervate was formed. I understand. In addition, it can be seen that the skin cleansing composition having a diluted solution with an absorbance of 0.8 or more gives a high moisturizing feeling to the skin after drying with a towel. In addition, good results were obtained for foam volume, foam quality, cleansing performance, washability, and irritation. On the other hand, as in Comparative Example 2, no coacervate is formed when the component (B) is not blended. Also, as in Comparative Examples 3 to 8, when the molar ratio of structural units derived from dimethyldiallylammonium chloride in the cationic polymer to be blended is low, no coacervate is formed with the fatty acid salt. In addition, as in Comparative Example 6, when component (C) was not added, the cleansing performance was low, and since the amount of coacervate produced was small, the feeling of moisturizing the skin after drying with a towel was low.
