Abstract

PURPOSE:The titled agent which contains a mercapto group-free peptide or its derivative and a buffering agent under specific conditions is applied to hair and heated to form hair waves safely through simple operations at relatively low temperatures in a shorter time. CONSTITUTION:The titled agent which contains 0.01-5wt% of a mercaptogroup- free peptide or its derivative and 0.05-10wt% of a buffering agent and has a pH of 8-10.5 is applied to hair and the hair is heated at 40-140 deg.C to give the hair waves. The peptide is preferably selected from polylysine, keratin, hydrolyzate of soybean protein and insulin. Since it includes no alkali agent of a high pH, reducing agent and oxidizing agent, the damage of hair and irritation to skins are reduced. Further, the treatment therewith forms equal to or better waves than conventional cold wave setting.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating treatment agent for hair deformation and a hair deformation method, and more specifically, the present invention relates to a heating treatment agent for hair deformation and a hair deformation method. The present invention relates to a heating type hair deforming treatment agent capable of semi-permanently deforming hair only by heating without using a sexual substance, and a hair deforming method using the same.

The way to give your hair the desired wave is to use a high pH initially.
This was a hair modification method called denso, which heated the hair using an alkaline water bath. The most commonly used method in recent years is to remove the s-8 bonds in the hair using the first agent Q-Manent Wave, which mainly contains reducing agents such as thioglycolic acid, cysteine, and sulfites. Reductive opening and then bromate, peroxide #1. This is the so-called cold Q-manent method in which oxidative closure is performed using a second agent of Q-manent wave whose main component is an oxidizing agent such as salt or hydrogen peroxide.

However, these methods have the disadvantage that hair strength decreases and texture deteriorates due to exposure to high pH alkaline water bath solutions, high temperature heating, reduction, and oxidation. Because it uses high-temperature heating and highly irritating chemicals, it had to be used with caution from a safety standpoint.

The present inventor has developed a method for deforming hair, and in particular Takada's alkaline water bath solution, which can deform hair semi-permanently like the waves obtained by conventional noq-manent waves, and which does not damage the hair. We were actively investigating a method that does not use oxidizing agents or reducing agents, and found that a method containing a peptide or its derivative that does not have a mercapto group and adjusting the pH to a range of 8 to 10.5 using a buffer. When the treatment agent for hair deformation is applied to hair and then heated, the hair will be semi-permanently deformed, and the treatment agent does not use a reducing agent or oxidizing agent, and 1) has low H. Furthermore, the present invention was completed based on the discovery that since the heating temperature may be low, it is extremely safe for hair and skin.

Therefore, the present invention provides a heating type hair modification treatment agent containing a peptide or a derivative thereof and a buffer and having a pH of 8 to 10.5, and applying this treatment agent to hair, and then treating the hair with a pH of 40 to 160. The present invention provides a method for deforming hair, which is characterized by heating the hair to a temperature of .degree.

Examples of peptides or derivatives thereof that do not have a mercapto group used in the present invention include (1) peptides having two or more amino acids synthesized from one or two basic amino acids (e.g., lysine, arginine), or acidic amino acids; Dimeric or higher peptides synthesized from one or two of the following (e.g., glutamic acid, Asno-9-ragi/acid); Hydrolyzate produced by the method described in JP-A-57-85308 etc. as a decomposed derivative of protein or soybean protein; (3
) Naturally occurring hormones or bioactive pezotides such as insulin, oxidative glutathione, etc.

XI of these? Lylizone; a hydrolyzate of keratin protein, soybean protein, etc.; and insulin are particularly preferred.

The heating-type hair modification treatment agent of the present invention (hereinafter simply referred to as "treatment agent") contains the above-mentioned bezotide or its derivatives alone or in combination of two or more. Oxt%

Buffers used in the present invention include, for example, citric acid/disodium hydrogen phosphate, hydrochloric acid/sodium parbital,
/ Sodium acetate, hydrochloric acid or maleic acid / Trishydroxyaminomethane, potassium or sodium dihydrogen phosphate / Dipotassium hydrogen phosphate, or sodium, hydrochloric acid or potassium or sodium dihydrogen phosphate / Sodium tetraborate, dihydrogen phosphate Potassium or sodium/sodium or potassium hydroxide, salt #/colicin, porium #2/storium carbonate or sodium tetraborate, hydrochloric acid/aminomenalzolono-Q-enzool, glycine/zitorium hydrate or potassium, porium/water 1 lium N j'X
4F&/sodium dimethylglycine, sodium bicarbonate/sodium carbonate, sodium tetraborate/sodium hydroxide, sodium bicarbonate/sodium hydroxide, or water-soluble ammonia tetrasalt/ammonia combinations. Among these, the combination of water-bathable ammonium salt/ammonia is preferred as it is volatile, does not easily leave alkaline agents in the hair, skin, etc., and causes less hair damage or skin irritation.As the water-bathable ammonium salt, hydrochloride , carbonates and bicarbonates are preferred.

Buffers can be, for example, when used in a water-soluble ammonium salt/ammonia combination, water-bathable ammonium salts, such as ammonium bicarbonate, ammonium carbonate or ammonium chloride, in the treatment agent of the invention at 0.05 to 10%, preferably = It is used by mixing 0.1 to 5.0% of 8-glue and adjusting the pH to 8.0 to 10.5 with ammonia. The above buffering agent may be used alone or in combination in the processing agent of the present invention.
More than one species can be used in combination.

In addition to the above-mentioned essential components, the treatment agent of the present invention may contain suitable commonly used oils, penetrants, wetting agents, colorants, emulsifiers, fragrances, and the like.

The method of using the processing agent of the present invention obtained as described above is as follows. First of all, it is preferable to wrap the hair around a rod, curler, heatable handy tie set device, etc. to form the desired waves before applying the treatment agent to the hair. If you want gentle waves, use a hair dryer or brush.
It can be shaped using the normal blow finishing method. Although the amount of application varies depending on conditions such as heating temperature, it is usually preferable to set it to 10 to 150 per application. The hair is then heated to 40-160°C. The heating temperature and time will vary depending on the degree of hair damage, the type of pezotide used, the type of buffer, and the formulation of the pH 1 treatment agent. For this reason, treatment at a high temperature is advantageous, but in consideration of damage to the hair due to heating, a temperature between 40 and 160°C, particularly between 40 and 80°C is preferred. Father, if you cover the hair with a cap and humidify it to prevent moisture from evaporating from the hair when heating it, it will cause premature growth. Although the heating time requires a low temperature phase and a long time, for the same reason, the heating time is preferably 30 minutes or less, and preferably between 3 and 10 minutes.

On the other hand, for chemically treated hair that has been treated with e-ma, hair dye, bleach, etc., it is desirable to select milder -a+ treatment conditions.

According to the present invention, strong waves can be formed on hair in a relatively low temperature and in a short time by simple operations. -4 does not use highly concentrated alkaline agents, reducing substances, or oxidizing substances, so it can reduce hair damage caused by leaching of hair proteins, has less irritation to the skin, and has storage stability. It has the advantage that it can also solve the various handling problems of conventional Q-manentwave agents.

The present invention will be explained below with reference to examples. The present invention is not limited to these embodiments.
