Description

  The present invention relates to a cleaning composition.

  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. In the case of higher fatty acid salts, the shorter the fatty acid chain length, the better the foaming properties but the poorer the foam quality.The longer the fatty acid chain length, the better the foam quality, but the stability over time. It tends to cause problems.

  Moreover, there are an example (Patent Document 1) used in combination with a polyoxypropylene adduct of diglycerin and an example (Patent Document 2) used together with a plant extract in order to improve the roughness of the skin after washing and the feeling of firmness. However, they are not effective enough to solve the problem.

  It is known that saccharides such as sorbitol and maltitol and nonionic surfactants are blended in the detergent for the purpose of preventing excessive degreasing (Non-patent Document 1).

  Conventional moisturizing effects such as higher fatty acid salts, saccharides, and nonionic surfactants are slightly enhanced. However, the improvement of foam quality, such as the roughness of foam texture and the lack of elasticity, is characteristic of higher fatty acid soaps. Was not reached. Accordingly, an object of the present invention is to provide a detergent composition having a detergency, a moist feeling after washing, and a foamy cleaning composition, although it is based on a higher fatty acid salt.

The present invention provides a cleaning composition containing the following (A) to (C).
(A) Higher fatty acid salt (B) One or more kinds selected from monosaccharides and / or disaccharides having 4 or more carbon atoms and nonionic surfactants having an HLB value of 12 or more (C) Acylamino acid powder

  The cleaning composition of the present invention exhibits the effects of excellent cleaning power, moist feeling after washing, and foam quality.

  Hereinafter, modes for carrying out the present invention will be described.

  The higher fatty acid constituting the higher fatty acid salt used in the present invention may be saturated or unsaturated, and those having 8 to 24 carbon atoms, particularly 10 to 22 carbon atoms are preferred. Among these fatty acids, it is preferable to use a linear saturated fatty acid. Specific examples of preferable ones include lauric acid, myristic acid, palmitic acid, stearic acid, coconut oil fatty acid, reduced coconut oil fatty acid, and palm kernel fatty acid. Among these fatty acids, it is preferable to contain one or more selected from lauric acid, myristic acid, palmitic acid and stearic acid from the viewpoints of foaming, safety and stability. Examples of alkali agents that form salts with these higher fatty acids include alkali metal salts such as sodium and potassium, ammonium salts, monoethanolamine, diethanolamine, triethanolamine, 2-amino-2-methylpropanol, and 2-amino-2. -Alkanolamine salts such as methylpropanediol, basic amino acid salts such as lysine and arginine, and the like. Of these, potassium and arginine are particularly preferable.

  Moreover, these higher fatty acid salts do not necessarily need to be blended in the cleaning composition as fatty acid salts, and the higher fatty acids and bases may be added separately to form fatty acid salts in the composition.

  The amount of the higher fatty acid salt varies depending on the dosage form of the cleaning composition and is not particularly limited. In the case of a solid detergent, the blending amount is preferably 90% by mass or less. In the case of a paste-like cleaning material, it is preferably 55% by mass. In the case of liquid cosmetics, it is preferably 25% by mass.

  The monosaccharide and / or disaccharide having 4 or more carbon atoms used in the present invention is not particularly limited as long as it can be used for a cleaning material. Examples of such monosaccharides and / or disaccharides include sorbitol, glucose, erythritol, mannitol, fructose, xylitol, sucrose, lactose, maltose, maltitol, trehalose and the like. Among such sugars, sorbitol is preferably used from the viewpoint of the effect of the present invention.

  Although the compounding quantity in the case of mix | blending 1 type, or 2 or more types chosen from C4 or more monosaccharide and / or 2 saccharides is not specifically limited, 1-20 mass% is preferable with respect to the cleaning composition whole quantity. .

  As the nonionic surfactant having an HLB value of 12 or more used in the present invention, any nonionic surfactant may be used as long as it is used in a normal cleaning composition.
