Description

  The present invention relates to a cleaning material.

  Conventionally, various products have been developed as detergents, and those based on higher fatty acid salts have excellent detergency, good foaming, and a refreshing feel. Etc. are used. However, due to its strong cleaning power, it has dropped to the sebum necessary for the skin, and there has been a problem that the skin becomes thick and squeezed after cleaning.

  There are examples (Patent Document 1) in combination with polyoxypropylene adducts of diglycerin and examples (Patent Document 2) in combination with plant extracts for improving the roughness of the skin after washing and the feeling of firmness. Is not effective enough to solve the problem.

  Therefore, an object of the present invention is to provide a highly stable cleaning material that solves the above problems, has good foaming and foam quality, has an excellent moisturizing effect, and the like.

That is, this invention provides the washing | cleaning material characterized by containing the following (A)-(D).
(A) Higher fatty acid salt (B) Tamarind gum (C) Difatty acid acyl glutamic acid lysine (D) Glucopyranosylglycerol

  According to the present invention, a highly stable cleaning material having good foaming and foam quality, excellent moisturizing effect, and the like can be obtained.

  Although the component (A) higher fatty acid salt used in the present invention is not particularly limited, a higher fatty acid salt neutralized in advance may be blended, or a higher fatty acid salt is formed by neutralizing a higher fatty acid and a base. And may be blended. As the higher fatty acid, any of saturated, unsaturated, straight chain, and branched fatty acids can be used, and those having 8 to 24 carbon atoms are preferable. Specifically, lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, isostearic acid, undecylenic acid, 2-palmitoleic acid, oleic acid, ricinoleic acid, linoleic acid, linolenic acid, arachidonic acid, coconut oil fatty acid, A palm kernel oil fatty acid etc. can be mentioned. Bases for producing higher fatty acid salts include inorganic bases such as sodium, potassium and magnesium, alkanolamines such as ammonium, monoethanolamine, diethanolamine, triethanolamine and 2-amino-2-methylpropanol, lysine and arginine. And basic amino acids. Among these, it is preferable to use one obtained by neutralizing palmitic acid, myristic acid and stearic acid with potassium hydroxide.

  A component (A) may be used individually by 1 type, and may use 2 or more types together, and the compounding quantity of 25-40 mass% is preferable with respect to the washing | cleaning agent whole quantity of this invention. If the blending amount is less than 25% by mass or exceeds 40% by mass, stability may be affected.

  Component (B) tamarind gum used in the present invention is derived from tamarind seeds, and is a water-soluble polymeric polysaccharide called xyloglucan having glucose as the main chain and xylose and galactose as the side chain, It can be used without particular limitation.

  A component (B) may be used individually by 1 type, and may use 2 or more types together, and the compounding quantity of 0.02-1 mass% is preferable with respect to the washing | cleaning agent whole quantity of this invention. When the blending amount is less than 0.02% by mass, foam quality may be affected, and when it exceeds 1% by mass, stability may be affected.

  As a commercial item of a component (B), Griloid 6C (made by DSP Gokyo Food & Chemical Co., Ltd.) etc. can be mentioned.

  Component (C) Di-fatty acid acyl glutamic acid lysine used in the present invention can be synthesized by reacting lysine hydrochloride and fatty acid acyl glutamic acid, and can be formulated in free form or in the form of a salt. You can also. The salt can be used without particular limitation, alkali metal salts such as sodium salt and potassium salt, alkaline earth metal salts such as calcium salt and magnesium salt, ammonium salt, triethanolamine salt, monoethanolamine salt, etc. And organic amine salts thereof. As the fatty acid of the acyl group, any of saturated, unsaturated, linear and branched fatty acids can be used. Specifically, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, behen. Examples thereof include acids, isostearic acid, undecylenic acid, petroceric acid, oleic acid, ricinoleic acid, linoleic acid, linolenic acid, arachidonic acid, coconut oil fatty acid, and palm kernel oil fatty acid. Among these, it is preferable to use dilauroyl glutamate lysine and / or a salt thereof.

  Component (C) may be used singly or in combination of two or more, and the blending amount is preferably 0.02 to 0.3% by mass relative to the total amount of the cleaning material of the present invention. . If the blending amount is less than 0.02%, the foam quality and the moisturizing effect may be affected, and if it exceeds 0.3% by mass, the stability may be affected. Examples of commercially available products include Perisea L-30 (manufactured by Asahi Kasei Chemicals Corporation).

  The component (D) glucopyranosylglycerol used in the present invention can be synthesized by reacting glycerin and glucose, and any of α-form, β-form, or a mixture thereof can be used.

  A component (D) may be used individually by 1 type, and may use 2 or more types together, and the compounding quantity of 0.02-1 mass% is preferable with respect to the washing | cleaning agent whole quantity of this invention. When the blending amount is less than 0.02% by mass, the foam quality and the moisturizing effect may be affected, and when it exceeds 1% by mass, the stability may be affected.

  In the cleaning material of the present invention, in addition to the above-described components, optional components used in the normal cosmetic field and the like can be blended to such an extent that the effects of the present invention are not impaired. Specific examples include purified water, oils, surfactants, thickeners, preservatives, fragrances, ultraviolet absorbers, moisturizers, antioxidants, anti-inflammatory agents, antibacterial agents, and the like.
