Description

  The present invention relates to skin cleanser compositions.

As a skin cleansing agent which is mild to the skin and excellent in feeling in use, for example, a cream containing a high amount of N-acyl amino acid salt, sulfosuccinic acid type surfactant, HLB 10 or more nonionic surfactant and polyhydric alcohol Additives are known (Patent Document 1).

  Although the cream-like face wash described in Patent Document 1 is a face wash having a high foaming power and a large amount of foam, there is room for improvement in high-temperature stability. Moreover, when 35 mass% or more of polyhydric alcohol was mix | blended, there existed a tendency for the foam amount, the texture fineness of a foam, and the moist and wash-up feeling to fall. On the other hand, although the detergent compositions described in Patent Documents 2 and 3 show a certain improvement in fast foamability and foamy creaminess, they can not be said to be sufficient from recent consumer requirements, and furthermore There was room for improvement.

  Therefore, as a result of various investigations to develop a cleansing composition for the skin in which the above-mentioned problems are solved, the present inventors have found that a specific cross-linked starch, N-acyl amino acid salt, polyoxyethylene alkyl sulfosuccinate and / or alkyl By combining and using a sulfosuccinate salt and a nonionic surfactant of HLB 9 to 14.5, the high temperature stability is excellent even when the polyhydric alcohol is contained at a high concentration (35 to 62% by mass), and the foaming occurs. The present inventors have completed the present invention by finding that a skin cleanser composition having excellent foam quality characteristics such as fineness of texture and texture of foam can be obtained.

The present invention provides the following components (A), (B), (C), (D) and (E):

  The skin cleanser composition of the present invention is excellent in high temperature stability, quick foam, has a large amount of foam, is excellent in foam characteristics such as fine texture of foam, and can obtain moist feeling after washing It is.

  Component (A) used in the present invention is a cross-linked product in which hydroxyalkyl modified starches having 2 to 5 carbon atoms are crosslinked, and hydroxyalkyl modified starches having 2 to 5 carbon atoms and acyl modified starches having 2 to 18 carbon atoms A cross-linked product, at least one cross-linked product selected from cross-linked products in which acyl modified starches having 2 to 18 carbon atoms are cross-linked; hydroxyalkyl modified starches having 2 to 5 carbon atoms; The two modified starches of the acyl modified starch of the present invention are cross-linked between the same species or species (see JP-A-2000-514435).

  The “hydroxyalkyl-modified starch having 2 to 5 carbon atoms” is a starch in which a hydroxyl group is bonded to a starch skeleton via an alkyl group having 2 to 5 carbon atoms, and a suitable balance of hydrophilicity-lipophilicity of starch. Is obtained. The position of the hydroxyl group in the alkyl group is not critical and can be at any position. The degree of substitution by hydroxyalkylation is preferably 0.08 to 0.3. The degree of substitution is the average number of hydroxyl groups of the starch molecule per unit of anhydroglucose. Hydroxyalkylation of natural starch is achieved by reacting the natural starch with an alkene oxide having the appropriate number of carbon atoms. Preferred is hydroxyethylated starch and / or hydroxypropylated starch obtained by reacting starch with ethylene oxide or propylene oxide. In addition, you may have several hydroxyl groups per alkyl group.

The "C2-C18 acyl-modified starch" is a starch acylated by a C2-C18 acyl group, and a suitable balance of hydrophilicity / lipophilicity of starch can be obtained. Acylation is usually carried out by reaction with an acid anhydride represented by the general formula (R-CO) ₂ O. Here, R represents an alkyl group such as a methyl group or an ethyl group.

  The crosslinking of these modified starches can be carried out by means of suitable crosslinking agents, for example difunctional compounds.
