Abstract

PURPOSE:To obtain a detergent composition which can give fine and creamy froth and is moist to the hair, skin, etc. by mixing an alkylsaccharide-type surfactant with a normally pasty oil. CONSTITUTION:This detergent composition is prepared by mixing an alkylsaccharide-type surfactant (A) with a normally pasty oil (B) (e.g. lanolin or choresteryl hydroxystearate) as the essential components. A representative example of component A is a compound of the formula (wherein R<1> is 6-18C linear or branched alkyl, alkenyl or alkylphenyl; R<2> is 2-4C alkylene; G is a 5 or 6C reducing sugar; (t) is 0-10; and (p) is 1-10). A desirable example of component B is an oil having a consistency of 20-200 as measured at 10 deg.C according to JIS-K2524. This composition is desirable for shampoos, skin detergents, etc.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a detergent composition which is preferably used as a shampoo, a skin cleanser, etc.
More specifically, it is possible to obtain a fine and slippery creamy foam quality, which is mild to hair and skin, and has a moist and slippery feel to hair.
The present invention relates to a detergent composition which gives a dry feel and a moist feeling to the skin.

[0002]

2. Description of the Related Art Conventional detergents such as shampoos are mainly composed of anion activators such as alkyl sulfates and polyoxyethylene alkyl sulfates. On the other hand, since the hair and stratum corneum washed by this are made of keratin protein, the protein is denatured by an anion activator,
It is known to damage the skin and hair.

For this reason, a nonionic shampoo has been proposed as a shampoo composition with less damage (Japanese Patent Laid-Open No. 53-13609).
Polyoxyethylene sorbitan ester (TWEEN) and alkyl glucosides are disclosed as nonionic surfactants. However, generally, a nonionic surfactant has a rough foam quality, a small foam amount, and poor slippage, and the foam performance is not sufficient. Alkyl saccharides are known as a non-ionic surfactant having a foaming property, but these do not satisfy the basic performance such as foam quality as a shampoo, and also have a squeaky feel. Since it is strong, it was not satisfactory as a surfactant for shampoos and body shampoos.

[0004]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a detergent composition which causes less damage to hair and skin, has fine and smooth foaming, and has a good feeling of use.

[0005]

Means for Solving the Problems As a result of intensive studies to achieve the above object, the present inventors have found that an alkyl saccharide-based surfactant which is a nonionic surfactant and an oil agent which is a paste at room temperature. When used in combination with, it is a detergent composition that has a fine foam quality, is mild to hair and skin, and suppresses squeaky feeling to the touch and gives a smooth and moist feeling to hair and skin. They have found that they can obtain a product, and have completed the present invention.

That is, the present invention provides a detergent composition comprising the following components (A) and (B) (A) an alkyl saccharide-based surfactant (B) an oil agent which is in a paste form at room temperature. It is provided.

The present invention will be described in more detail below. Typical examples of the alkyl saccharide-based surfactant of the component (A) used in the present invention include compounds represented by the following general formula (1). R ¹ —O— (R ² O) _t — (G) _p (1) [wherein, R ¹ represents a linear or branched alkyl, alkenyl or alkylphenyl group having 6 to 18 carbon atoms,
R ² represents an alkylene group having 2 to 4 carbon atoms, G represents a reducing sugar having 5 to 6 carbon atoms, t represents a number of 0 to 10 and p represents a number of 1 to 10]

Alkyl saccharla represented by the general formula (1)
As the id-based surfactant, R¹Has 6 to 18 carbon atoms, special
An alkyl group having 8 to 12 carbon atoms (octyl group, decyl group
Groups, lauryl groups, etc.) are preferred. R²Is carbon

The amount of the alkyl saccharide as the component (A) to be added to the detergent composition is not particularly limited, but is preferably 1 to 50% by weight (hereinafter, simply referred to as%) in the total amount, and particularly 5 -30% is preferable.

In the present invention, as the oil agent of the component (B) used in combination with the above-mentioned component (A), which is a paste at room temperature,
It is not particularly limited as long as it is an oil agent which shows a paste form at 25 ° C. in a conventional method, but especially 10 ° C. measured according to JIS K2524 method (Petrolactam consistency test method)
Oils used in ordinary cosmetics, having a consistency in the range of 20 to 200, are preferred. Particularly preferably, 10
It is an oil agent having a consistency in the range of 30 to 120 at ° C. Here, the oily agent having a consistency of less than 20 is close to a solid state, and when it is added to a detergent composition, the hair becomes stiff and
It gives a squeaky feeling to the skin, lacks a moist feeling, and an oil having a consistency of more than 200 has too high fluidity. When this is added to a detergent composition, it gives a feeling of stickiness to hair and skin after washing. In addition, it has a drawback that the cleaning power is significantly reduced, which is not preferable.

Examples of the oily agent having a consistency in the range of 20 to 200 include pasty fats and oils such as beef tallow, sheep fat, horse fat, and lard; lanolin, lanolin acetate, lanolin fatty acid isopropyl, polyoxyethylene (POE) cholesteryl ether. Hydrocarbon paste oils such as lanolin fatty acid polyethylene glycol and petrolatum; cholesteryl hydroxystearate, dipentaerythritol fatty acid ester, trimethylolpropane tri-2-ethylhexylate, trimethylolpropane triisostearate,
Examples of the paste-like ester oil include tetra-2-ethylhexyl pentane erythritol. In the present invention, among these components (B), cholesteryl hydroxystearate, dipentaerythritol fatty acid ester, and lanolin are particularly preferable.

The amount of component (B), which is in the form of paste at room temperature, in the detergent composition is 0.1 to 2 out of the total amount.
0% is preferable, and 1.0-10% is more preferable. If the blending amount is less than 0.1%, it gives a squeaky feeling to the hair or skin, and it is not preferable because the hair does not pass smoothly through the fingers or a good feel is not obtained, and if the blending amount exceeds 20%, the stability of the system is improved. Is not preferable, and stickiness is caused, and the fingers cannot easily pass through the hair.

In addition to the above-mentioned essential components, various optional components can be added to the cleaning composition of the present invention, if necessary.
