Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an oil-in-alcohol type emulsified hair cosmetic. More specifically, for hair
The present invention relates to an oil-in-alcohol-type emulsified hair cosmetic which can give excellent luster and impart a smooth feel, and can adhere and repair split ends of hair.

[0002]

2. Description of the Related Art Conventionally, hair cosmetics contain oils such as silicone oil, high molecular weight dimethylpolysiloxane, high molecular weight methylphenylpolysiloxane, ester oil and hydrocarbon oil for the purpose of giving the hair smoothness. , Solubilization,
It is used after emulsification and dissolution.

In particular, silicone oil has a low surface tension,
Because it is excellent in hair familiarity and good gloss is obtained,
It is frequently used in recent years.

[0004]

However, there is a limit to the oil content, and when used in large quantities or when used for a long period of time,
There was a problem that hair became greasy.

[0005] Cationic surfactants are also frequently used for the purpose of imparting smoothness to hair. However, they do not give satisfactory satisfactory smoothness.
There was a problem that this was not good in terms of safety.

[0006] In general, hair is remarkably damaged by frequent repetition of hair washing, brushing, heat with a dryer, hair coloring, and a bleaching treatment, and as a result, the hair becomes dry and lumps or split ends. , Cut hair,
It is well known that it causes an increase in hair loss and the like and a decrease in strength.

On the other hand, conventionally, dimethyl silicone gum, polyvinylpyrrolidone-based polymer, acrylic acid-based polymer, polysaccharide, polypeptide and the like have been blended in hair cosmetics for the purpose of coating the split ends of hair.

[0008] Recently, it has been reported that hair cosmetics using a combination of a polysiloxane-oxyalkylene copolymer and a silicone derivative impart a good feel to hair and have excellent adhesion of split ends. (JP-A-6-157247).

[0009] However, these methods are good in imparting an excellent feel to hair,
It was still incomplete with respect to the adhesive effect of the split ends and the gloss of the hair.

When another polymer compound is blended, it has an adhesive effect on the split ends, but once it is peeled off, the effect cannot be reproduced, but also it becomes squeaky, sticky, sticky, etc. There are many problems on the touch surface, and there are also problems in appearance such as flaking.

[0011] Therefore, there has been a demand for a hair cosmetic which can solve these problems, efficiently bond the split ends, and give the hair a gloss and a good feel to the hair.

The present inventor has conducted intensive studies in view of the above viewpoints. As a result, it has been found that oat seeds or oatmeal extracts are blended with an oil-in-alcohol emulsion obtained using a specific polyether-modified silicone as the sole emulsifier. The inventors have found that the above-mentioned problems can be solved and a hair cosmetic can be obtained with an emulsion stability, and have completed the present invention.

[0013] The present invention provides a hair cosmetic composition which has an excellent function of repairing split ends, smoothes the hair, imparts a good feel, prevents split ends, and gives the hair a good gloss. The purpose is to:

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail.

The hair cosmetic composition of the present invention is an oil-lower alcohol-water system in which a lower alcohol is present in excess with respect to water, and one or more polyether-modified silicones represented by the above general formula (1). This is an alcohol-in-alcohol type emulsified hair cosmetic using the above.

This oil-in-alcohol type emulsified hair cosmetic is
Completely different from conventional emulsification, it uses no hydrophilic nonionic surfactant, but rather uses polyether-modified silicone, which gels when contacted with water, as the only emulsifier, emulsifying oil in high alcohol concentration. It is an oil-in-alcohol type emulsified hair cosmetic containing an olive oil seed or oatmeal extract in an alcohol-in-alcohol emulsion.

The polyether-modified silicone (d) used in the present invention is an organopolysiloxane having a polyoxyalkylene group represented by the general formula (1) and disclosed in JP-A-5-311076. is there.
In the present invention, commercially available products can be used.

Specific examples of the acyl group of R 'in the polyoxyalkylene group include a formyl group, an acetyl group, a propionyl group, a butyryl group, an acryloyl group, a benzoyl group and a toluoyl group. Specific examples of the alkyl group of (1) to (4) include a methyl group, an ethyl group, and an i-
Examples thereof include a propyl group, an n-propyl group, a t-butyl group, and an n-butyl group.

In the polyoxyalkylene group,
When a or b is less than 5, the polyether-modified silicone does not show a sufficient surfactant effect, and when a or b exceeds 50, the obtained hair cosmetic has a sticky feeling. Become like

Although the content of the polyoxyalkylene group in the polyether-modified silicone is not particularly limited, it is preferable that the content of the polyoxyalkylene group exceeds 20% by weight. This is because when the content of the polyoxyalkylene group is 20% by weight or less, the emulsifying effect of the polyether-modified silicone is significantly reduced.

M is an integer of 50 to 1000;
n is an integer of 0 to 40. This is because when m is less than 50, the emulsion stability is poor, and when m is 1000
If n exceeds 40, the resulting hair cosmetic will have a sticky feeling.

Although the molecular weight of the polyether-modified silicone is not particularly limited, it is 20,000 from the viewpoint of stability and usability.

The amount of the lower alcohol is preferably 3 times or more (weight ratio) and 30 times or less (weight ratio) with respect to the amount of water in the hair cosmetic. If the amount of the lower alcohol is less than three times, the polyether-modified silicone acts as an alcohol-in-oil type emulsifier, causing phase inversion. When the amount exceeds 30 times, the stability of the emulsified particles may be deteriorated.

The amount of the lower alcohol is usually 30.0 to 95.0% by weight based on the total amount of the hair cosmetic. In the prior art, in view of the difficulty in emulsification of the oil-in-alcohol type at a high alcohol concentration, the blending amount of the lower alcohol is 30.
The importance of the present invention is particularly understood when it is 0% by weight or more, more preferably 50.0% by weight or more.

The ratio of water to the water-soluble organic solvent is preferably about 3: 1 to 1: 5 by weight, more preferably 2: 1.
１ ： 1: 2, most preferably about 1: 1.

The extract obtained by the above extraction method is
