DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdered hair treating agent, and more particularly, to a powdered hair treating agent which can be added to hair cosmetics and replenished with an oily adjusting component suitable for human hair. Things.

[0002]

2. Description of the Related Art Many conventional hair cosmetics, such as "for damaged hair" and "for dry hair," are available on the market according to the type of hair, but since they are intended for an unspecified number of consumers, For some people, the hair was not always satisfactory, for example, the hair was rough and the finished feel and gloss were not sufficiently effective.

[0003] Therefore, it is conceivable to replenish an oily control component to the hair when using the hair cosmetic product and adjust the hair control product to one suitable for the hair quality of the user. However, even if the oily control component is directly added to the hair cosmetic product, It could not be uniformly dissolved and mixed, and was also inconvenient in terms of stability. on the other hand,
It is known to incorporate urea, which has a moisturizing effect on hair, into hair cosmetics.However, urea gradually decomposes in the presence of water, and in particular, decomposes remarkably in the presence of acid or alkali. It was difficult to mix urea.

[0004]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention provides a hair treatment agent suitable for the hair quality of a user by appropriately adding an oiliness control component to hair cosmetics, and the hair finish after treatment is extremely good. It is intended to provide a powdered hair treatment agent that is:

[0005]

The present inventors have made various studies to achieve the above object, and as a result, have used an oiliness controlling component as an inclusion compound of urea and added a polypeptide.
By using it as an agent, it has good mixed solubility in hair cosmetics, and both the oily control component and urea are stably present. As a result, the conditioning effect of the oily control component does not cause the hair to pat, and it has a glossy finish. The present inventors have found that a certain moist finish is obtained and completed the present invention.

Hereinafter, the configuration of the present invention will be described in detail. In the present invention, the target oiliness adjusting component includes:
It is a compound that has been used for the purpose of adjusting the oil content of hair conventionally, and is usually a hydrocarbon such as paraffin, cetyl alcohol, oleyl alcohol, lauryl alcohol, stearyl alcohol, cetostearyl alcohol, myristyl alcohol, behenyl alcohol, etc. Alcohols, isopropyl myristate, butyl myristate, isopropyl palmitate, butyl stearylate, methyl stearylate, fatty acid esters such as ethyl oleate, lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, oleic acid,
Examples include higher fatty acids such as coconut oil fatty acids, and surfactants such as polyoxyethylene lauryl ether, polyoxyethylene cetyl ether, polyoxyethylene stearyl ether, polyoxyethylene behenyl ether, and polyoxyethylene oleyl ether. The number of moles of ethylene oxide added to the surfactant is 1
~ 5 are preferred. Among these oiliness adjusting components, oleyl alcohol, isopropyl myristate, isopropyl palmitate, butyl stearate,
Cetyl alcohol and oleic acid are preferred.

In the present invention, it is essential that the above-mentioned oily control component is used as a urea inclusion compound, but the ratio of urea to the oily control component is usually 9: 1 to 1: 1.
1: 1 (weight ratio). As a method for preparing an inclusion compound of an oiliness adjusting component and urea, usually, a crystal of the inclusion compound can be obtained by mixing the oiliness adjusting component with a saturated aqueous solution of urea or a saturated methanol solution. At this time, it is preferable to dissolve the oiliness adjusting component in an organic solvent such as ethyl methyl ketone, isobutyl methyl ketone, Sec-butyl alcohol, or methylene chloride in advance and to supply it, because the formation of the inclusion compound is promoted. Next, the generated crystals of the clathrate can be recovered by filtration, washing and drying. When two or more clathrate compounds are prepared, they may be prepared separately,
A mixture of clathrates can be recovered by simultaneously supplying two or more oiliness adjusting components.

The content of the clathrate compound of the oily control component and urea in the powdery hair treatment composition of the present invention is usually 10 to 1
00% by weight, preferably 30 to 100% by weight. In the present invention, additives such as a polypeptide and a thickener can be further blended, and a more excellent hair treatment effect can be obtained by the action of these additives. Specific examples of the polypeptide include, for example, a hydrolyzate obtained by hydrolyzing a protein such as collagen, keratin, elastin, fibroin, conchiolin, soybean protein, and casein with an acid, an alkali, an enzyme, or the like. Graded cation-denatured proteins, and as the thickener, for example, starchy, seaweed, sodium alginate, methylcellulose, hydroxyethylcellulose, carboxymethylcellulose, guar gum, xanthan gum, quaternary nitrogen-containing cellulose ether And the like.

The powdery hair treating agent of the present invention may be dissolved in water or warm water and applied to the hair as it is.
It is desirable to use it by adding it to known hair cosmetics. In this case, hair cosmetics are usually shampoo, rinse,
Treatments, conditioners, set lotions, hair tonics, permanent wave agents, hair dyes, and the like. The amount of addition is determined by the hair quality of the user, but is usually 1 to 70% by weight based on the hair cosmetics.
