Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid detergent composition, and more particularly to a liquid detergent composition capable of significantly reducing the friction resistance on the skin or hair.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
A liquid detergent composition for skin or hair contains a surfactant as a main component, and if necessary, a high-molecular polymer, a cationic surfactant, an oil agent, a conditioning agent such as silicone, a moisturizer, a bactericide, a fragrance, etc. are added. Has been done.

However, the above-mentioned conditioning agents, especially cationic activators, oil agents, silicones and the like, have the drawback of deteriorating the foam performance.

Therefore, it has been desired to develop a liquid detergent composition which reduces frictional resistance on the skin and hair and gives a smooth slippery feeling after washing and drying.

[0005]

Means for Solving the Problems The inventors of the present invention have made extensive studies in view of such circumstances, and as a result, a liquid detergent composition containing a specific long-chain alkyl sulfate described below has a good foaming on the skin and hair. It was found that the friction resistance can be remarkably reduced, and therefore a good sliding feeling can be provided after washing and drying, and the present invention has been completed.

That is, the present invention provides a liquid detergent composition containing 0.2 to 10.0% by weight of an alkyl sulfate having a linear or branched alkyl group having 16 to 22 carbon atoms. It is provided.

In the present specification, the "liquid detergent composition" also includes a normal "liquid" detergent composition and a so-called "paste" composition.

Preferred examples of the alkyl sulfate having a linear or branched alkyl group having 16 to 22 carbon atoms (preferably 18 to 22 carbon atoms) used in the present invention include the following alcohols and sulfuric acid. Ester of. Preferred alcohols include palmitol, hexyldecanol, stearyl alcohol, hexyldecanol, 5,7,7-trimethyl-2-.
Examples thereof include saturated alcohols such as (1,3,3-trimethylbutyl) octanol and behenyl alcohol, and unsaturated alcohols such as palmitooleyl alcohol, oleyl alcohol and ricinol alcohol.

The amount of the above alkyl sulphate to be added to the liquid detergent composition of the present invention is 0.2 to 10.0% by weight (hereinafter referred to simply as "%"), particularly 0.3 to 5.0%.
Is preferable for obtaining a good feel. The alkyl sulfates may be used alone or in combination of two or more.

Since the alkyl sulphate used in the present invention is strongly adsorbed to the skin and hair, it is possible to reduce the friction resistance after drying without desorption even after washing and rinsing.

The liquid detergent composition of the present invention may further contain one or more selected from nonionic surfactants, anionic surfactants and amphoteric surfactants to improve detergency, It is preferable in terms of improving foam performance.

Preferred examples of the nonionic surfactant include polyoxyethylene alkyl ether and the following general formula (1): R ¹ O (R ² O) _m G _n (1) (wherein R ¹ is carbon number 8-18 alkyl, alkylphenyl, shows a hydroxyalkyl or hydroxyalkyl phenyl group, R ² represents an alkyl group having 2 to 4 carbon atoms, G represents a reducing sugar residues from 5 or 6 carbon atoms, m represents a number of 0 to 5 and n represents a number of 1 to 3).

Preferred examples of the anionic surfactant include α-olefin sulfonate, ether sulfate having a C 10-14 alkyl group, mono- or dialkyl phosphate, alkyl sulfosuccinate,
A sulfate having an alkyl group having 10 to 14 carbon atoms,
Examples thereof include N-acyl amino acids, N-acyl taurine, acyl isethionate, and salts thereof.

Preferred examples of the amphoteric surfactant include those of imidazolium betaine type and sulfobetaine type.

The amount of the above-mentioned surfactant compounded in the liquid detergent composition of the present invention is preferably 100/1 to 1/1 in terms of the weight ratio with the alkyl sulfate, and particularly 100
The ratio of / 1 to 3/1 is preferable from the viewpoint of enhancing the cleaning power and the foaming power.

In the liquid detergent composition of the present invention, in addition to the above components, if necessary, anionic polymers, nonionic polymers, cationic polymers, conditioning agents, moisturizing agents, which have been conventionally added to detergents, are added. Agents, preservatives, perfumes, dyes, etc., as appropriate, within a range that does not impair the effects of the present invention,
It can be blended.

The liquid detergent composition of the present invention can be prepared by uniformly mixing the above compositions according to a conventional method. In addition, depending on the type and amount of the composition, it can be in liquid form or paste form.
