Description

[Technical field]

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

[0002] In recent years, as the spread of infection caused by the so-called new coronavirus has become more serious, regular use of masks is recommended as a measure to prevent infection. Wearing a mask can cause acne and rough skin due to moisture and stuffiness inside the mask, as well as friction between the mask and the skin, and many people suffer from skin problems.

[0003] In addition, concerns about pores, such as blackheads and open pores, are a permanent concern, especially among young people. Pores become noticeable when pores are clogged with keratin plugs, so neglecting pore care will lead to the proliferation of acne bacteria, which will cause acne. Although removing keratin plugs is a desirable cosmetic procedure, the method of removing keratin plugs using sheets or packs is complicated, as they are sticky and put a strain on the skin, and they need to be left to dry before being peeled off, so a simple method of removing keratin plugs was desired.

[0004] Skin cleansers containing bactericides have the effect of preventing acne, and various types are commercially available. Patent Document 1 proposes a skin cleansing composition containing bactericidal components consisting of triclosan, isopropylmethylphenol, and parachlorometaxylenol, but it is not satisfactory in terms of foam.

[0005] Furthermore, a cleansing composition that is filled into a foam container for use is discharged in a foam form by squeezing it out of the container, and therefore has excellent convenience in use, and from the viewpoint of reducing the burden on the skin caused by washing the skin with the foamed cleansing agent, various proposals have been made so far. Patent Document 2 proposes a skin cleansing composition that is discharged from a foam container into fine foam, but it does not have a bactericidal effect or a keratin plug removing effect.

[0011] The skin cleansing composition of the present invention will be described in detail below.

[0012] [Skin cleansing composition] The skin cleansing composition of the present invention contains at least (A) isopropylmethylphenol, (B) an N-acyltaurine type anionic surfactant represented by the following general formula (1), and (C) a polyoxyethylene alkyl ether type nonionic surfactant. R1CO-NR2-CH2CH2SO3M (1) (In general formula (1), R1 represents a saturated or unsaturated hydrocarbon group having 7 to 19 carbon atoms, R2 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, and M represents an alkali metal atom, an alkaline earth metal atom, ammonium, an organic ammonium, or a basic amino acid.)

[0013] The skin cleansing composition of the present invention can be used, for example, in facial cleansing foams, cleansing products, body soaps, hand soaps, shaving products, and the like.

[0014] The formulation of the skin cleansing composition can be arbitrarily selected from known formulations depending on the application, purpose of use, etc. For example, it can be in the form of a liquid, cream, etc.

[0015] In this specification, "dischargeability at low temperatures" refers to the ability to prevent pump clogging even at low temperatures and to easily discharge the composition from the foamer container, and "low-temperature stability" refers to the ability to maintain a transparent appearance and to be free of precipitates even after long-term storage (about one month) at low temperatures (about 5°C).

[0016] <Component (A)> The component (A) used in the skin cleansing composition of the present invention is isopropyl methylphenol. By adding the component (A), it is possible to impart a bactericidal effect.

[0017] In the cleaning composition of the present invention, the blending amount of the (A) component is preferably 0.05% by mass or more and 1.0% by mass or less. If the blending amount of the (A) component is 0.05% by mass or more, a sufficient bactericidal effect can be obtained. Also, if the blending amount of the (A) component is 1.0% by mass or less, the raw material odor of isopropyl methylphenol itself is suppressed, and the preference during use is increased.

[0018] <(B) component> The component (B) used in the skin cleansing composition of the present invention is an N-acyltaurine type anionic surfactant represented by the following general formula (1). R1CO-NR2-CH2CH2SO3M (1) (In general formula (1), R1 represents a saturated or unsaturated hydrocarbon group having 7 to 19 carbon atoms, R2 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, and M represents an alkali metal atom, an alkaline earth metal atom, ammonium, an organic ammonium, or a basic amino acid.)

[0019] Specific examples of the N-acyltaurine type anionic surfactant represented by general formula (1) include, but are not limited to, N-lauroyl-N-methyltaurine salt, N-myristoyl-N-methyltaurine salt, N-cocoyl-N-methyltaurine salt, N-lauroyl-N-ethyltaurine salt, N-myristoyl-N-ethyltaurine salt, N-cocoyl-N-ethyltaurine salt, N-lauroyltaurine salt, N-cocoyltaurine salt, etc. The above-mentioned N-acyltaurine type anionic surfactant can be used alone or in combination of two or more.

The N-acyltaurine type anionic surfactant can be a commercially available product, and examples thereof include Diapon K-SF (manufactured by NOF Corp.) and Ampholex AM-1 (manufactured by Miyoshi Oil Co., Ltd.).

[0021] In the skin cleansing composition of the present invention, the blending amount of the (B) component is preferably 1% by mass or more and 6% by mass or less. When the blending amount of the (B) component is 1% by mass or more, sufficient foam durability can be obtained. On the other hand, when the blending amount of the (B) component is 6% by mass or less, sufficient low-temperature stability and dischargeability at low temperatures can be obtained.

[0022] <(C) component> The component (C) used in the skin cleansing composition of the present invention is a polyoxyethylene alkyl ether type nonionic surfactant. As the polyoxyethylene alkyl ether type nonionic surfactant, a polyoxyethylene alkyl ether having an alkyl group with a carbon number of 10 to 14, which is saturated or unsaturated, linear or branched, and has an average added mole number of ethylene oxide of 85 to 150 is preferred. Moreover, the polyoxyethylene alkyl ether type nonionic surfactant may be used alone or in combination of two or more kinds.
