Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition having an excellent feeling in use.

[0002]

2. Description of the Related Art Conventionally, detergents containing a surfactant such as higher fatty acid salt, N-acylglutamate, polyoxyethylene alkyl ether sulfate, etc. as a main component have been studied. .. However, since the higher fatty acid salt is alkaline, it is not preferable because it imposes a load on the skin, N-acyl glutamate is inferior in rinsing ease, and polyoxyethylene alkyl ether sulfate is inferior in skin irritation and rinsing ease. There was a problem.
Therefore, in order to improve these points, it has been attempted to add an amphoteric surfactant.

However, the detergent composition comprising this combination is almost satisfactory in terms of foaming and detergency, but it is not sufficiently excellent in feeling of use (no bulkiness).

As a result of intensive studies in view of such circumstances, the present inventors have found that the specific detergent composition described below has a good feeling in use (there is little bulkiness or tightness in the skin of fingers, etc.). It was found that the present invention has been completed.

That is, an object of the present invention is to provide a detergent composition having a good feeling in use.

[0006]

The above object is achieved by a detergent composition containing one or more anionic surfactants, one or more amphoteric surfactants and sorbitan fatty acid ester. To be achieved.

The structure of the present invention will be described in detail below. The anionic surfactant used in the present invention has one or more kinds of carboxyl groups, sulfuric acid ester groups, sulfonic acid groups, and phosphoric acid ester groups in the molecule, and those having a carboxyl group include alkyl ether carboxylic acids. Acid salts, N-acyl amino acid salts of condensates of amino acids and fatty acids, and the like having sulfonic acid groups, alkane sulfonates, alkane sulfosuccinates, alkylallyl and alkylnaphthalene sulfonates, N-acyl sulfonates. , Formalin condensed sulfonate, etc., having a sulfuric acid ester group, such as alkyl sulfate ester salt, alkyl ether sulfate, alkyl aryl ether sulfate, higher fatty acid amide sulfate, etc., having a phosphoric acid ester group is alkyl Phosphate ester salt, ether phosphate Ether salts, alkyl aryl ether phosphate salts, may be mentioned higher fatty amide phosphate salts, etc., one or two or more can be arbitrarily selected from these.

As the amphoteric surfactant used in the present invention, amidopropyl betaine, carboxybetaine, sulfobetaine, aminocarboxylic acid, imidazoline derivative, amine oxide, phospholipid, tertiary nitrogen or quaternary nitrogen-containing phosphate ester And the like, and one or two or more of these can be arbitrarily selected.

The amount of the anionic surfactant used in the present invention is preferably 5 to 30% by weight in the detergent composition,
More preferably, it is 10 to 25% by weight. The amount of the amphoteric surfactant used in the present invention is preferably 0.5 to 20% by weight, more preferably 5 to 20% by weight in the detergent composition.
It is 15% by weight. The total content of the anionic surfactant and the amphoteric surfactant in the detergent composition is preferably 5.5 to 50% by weight, more preferably 10 to 30% by weight.

Specific examples of the sorbitan fatty acid ester used in the present invention include sorbitan tristearate, sorbitan distearate, sorbitan trioleate, sorbitan dioleate, sorbitan tripalmitate, sorbitan dipalmitate and sorbitan trimyriate. State, sorbitan jimyri state, etc. are mentioned.

The amount of the sorbitan fatty acid ester used in the present invention is preferably 0.2 to 15% by weight, and more preferably 1 to 7% by weight in the detergent composition.

In addition to the above-mentioned essential components, the detergent composition of the present invention may optionally contain other components usually used. Other components, coconut oil fatty acid diethanolamide, glycerin fatty acid ester, nonionic surfactants such as polyoxyethylene alkyl ether, pearl brighteners such as fat iii ethylene glycol, chelating agents such as edetate, glycerin, sorbitol, Moisturizers such as maltitol and 1,3-butylene glycol, superfatting agents such as fatty acids, higher alcohols and fats, water-soluble polymers such as methyl cellulose and carboxyvinyl polymer, usability improvers such as cationized cellulose, and Examples include drugs such as glycyrrhizin, allantoin, and various vitamins.

The detergent composition of the present invention can be applied to hair, skin, kitchen detergent and the like. Furthermore, it is also useful for cleaning makeup cosmetics.

EXAMPLES The present invention will now be described in detail with reference to examples, but the present invention is not limited thereto. The blending amount is% by weight. Prior to the examples, the evaluation method will be described.

Sensory Test After Use A cleaning test was conducted by 10 sensory panelists, and the after-use feeling such as the presence or absence of bulkiness and tightness of the skin was evaluated according to the criteria of Table 1. Those having less bulkiness and tightness were considered good. The evaluation results were evaluated by 10 functional panelists of the Examples and Comparative Examples, and the average value of the evaluation points thereof was calculated.
It is indicated by the symbol.
