Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is directed to an e-manent wave second agent composition, more specifically, to suppress hair deterioration caused by Q-manent wave treatment and to improve the composition of one hair. The present invention relates to a NoQ permanent wave second agent composition that provides good touch and has excellent permanent wave retention.

[Conventional technology and its problems]

The e-manent wave method for giving hair the desired waves uses thioglycolic acid.

The main component is a reducing agent such as cysteine. 9-Manent Wave 1st agent (hereinafter referred to as ``1st agent'') is used to reduce and open the S-S bonds in the hair, and then an oxidizing agent such as bromate, perborate, hydrogen peroxide, etc. This is a method of oxidative closure using a permanent wave second agent (hereinafter referred to as "second agent") whose main component is

However, this method is subject to adverse conditions such as oxidation and reduction, which causes phenomena such as a decrease in the strength of the hair and a deterioration of the texture. The brush or comb does not go through well when applying hair.

This causes the hair to get caught, resulting in peeling of the hair epidermis, split ends, and cut hair, resulting in damage.

Hair deterioration phenomena occur at each stage of permanent wave processing. That is, since the first agent is mainly composed of a reducing agent and an alkaline agent, these agents swell the hair, destroy keratin proteins in the hair, and elute them as proteins and amino acids into the treatment solution. This swollen hair is then damaged by an oxidizing agent in treatment with a second agent.

However, this phenomenon caused by the first agent is due to the S-S in the hair.
is unavoidable for reductive opening of the bond and therefore IQ-? In order to prevent hair deterioration due to the Nentwave treatment, it is important for K to minimize damage caused by oxidation of the second agent.

Conventionally, a method for preventing hair damage caused by the second agent has been to incorporate an oil agent, a humectant, etc. into the composition, but this method has also not been satisfactory.

[Failure to solve the problem]

The present inventors conducted various studies on reducing hair damage caused by Noq-Manent Wave agents, especially the second agent, and found that if a specific keratin substance decomposition derivative is blended into the second agent base, the protein discovered that it is possible to obtain a second part composition that suppresses hair deterioration due to the elution of amino acids, gives a preferable feel to the hair, and has an excellent wave-holding effect compared to conventional second part compositions, and the present invention Completed the invention.

That is, in the present invention, one or more decomposed derivatives of keratin substances selected from the group consisting of (1) oxidative decomposition products of keratin substances and (2) derivatives in thiol groups of reductive decomposition products of keratin substances are blended into the second agent base. The present invention provides a second agent composition.

The decomposed derivatives of keratin substances of the present invention can be obtained either by oxidatively decomposing the keratin substance and converting it into an alkali salt if necessary; Manufactured by any of the following methods:

An example of a keratin material used as a raw material is animal hair.

Examples include hair, feathers, nails, horns, hooves, scales, etc. Among them, wool, hair and feathers are preferred.

These keratin substances can be directly subjected to oxidation or reduction reactions, if necessary.

Cut or crush into appropriate size, or wash.

Pretreatment such as degreasing may also be performed.

The decomposition of keratin substances is carried out by one of the following methods.

(1) Oxidation reaction The oxidation of the keratin material is carried out using various cage methods known per se [N, H,
L@an;Textll@Programs, Volume 7,
1 (1975)]. The oxidizing agent is preferably an organic or inorganic oxidizing agent that acts electrophilically on disulfide bonds (SS bonds) in the keratin structure.

Examples include organic peracids, inorganic, e-oxo acids or salts thereof, permanganic acid or salts thereof, chromic acid or related compounds, halogens, peroxides, oxygen acids or salts thereof, among others. Acetic acid.

Organic peracids such as performic acid and perbenzoic acid are particularly preferred.

The oxidation reaction is caused by the oxidation reaction of zosulfide in keratin materials (excess amount with respect to 2-do bond, usually 2 with respect to 1 disulfide bond).
It is carried out in a liquid medium using more than double equivalents of oxidizing agent, preferably 4 to 10 times equivalents. The reaction can be carried out under either acidic or alkaline conditions, but it is preferably carried out under acidic, particularly weakly acidic conditions. Conditions such as reaction temperature and pressure vary depending on the oxidizing agent used, the type of keratin material, etc., and are not particularly limited. Room temperature is generally sufficient, but heating can be performed as necessary, and the pressure may also be adjusted. Normal pressure is sufficient, but it may also be carried out under reduced pressure or increased pressure.

In doing so, the disulfide bonds of the keratin material are cleaved to produce sulfonic acid (-SO,U).

1. Reductive Decomposition and Chemical Modification Reactions Reducing agents used to reduce keratin materials include those that cleave disulfide bonds in the structure to give thiol groups (-sg), and generally those that have a demand for disulfide bonds. Organic or inorganic reducing agents of the nuclear-acting type are preferred. Specifically, organic reducing agents such as mercaptoethanol, thioglycolic acid, pencil mercaptan, 1,4-zothioslidele, and tributylphosphine; sulfides such as sodium bisulfite and sodium hydrosulfide.

Examples include inorganic reducing agents such as metal hydrides such as lithium aluminum hydride.

The amount of reducing agent used is generally 2 to 10 times equivalent to the disulfide bonds in the keratin material. The p■ value of the reaction system is preferably in the range of 2 to 12, particularly 6 to 11; anything outside this range is not preferred because hydrolysis occurs.

Room temperature is sufficient for the reaction temperature, but the reaction time can also be shortened by heating. The reaction time usually requires 2 to 3 hours or more.

It is also necessary that the thiol groups produced by this reduction are not substantially oxidized, and therefore good results are obtained if the operation is carried out in an inert gas atmosphere.

The thus obtained reductive decomposition product of the keratin substance is made into a derivative thereof (hereinafter referred to as a ``keratin substance reduced derivative'') by chemically modifying its thiol group. Examples of derivatives of the thiol group include primary ones.
