Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a first agent for permanent waving, and more particularly to a first agent for permanent waving for an iron perm for forming a wave on hair with a hairdressing iron. is there.

[0002]

2. Description of the Related Art Conventional permanent wave (hereinafter simply referred to as "perm") treatments have a reducing agent such as thioglycolic acid or cysteine as a main agent, and an alkaline agent such as ammonia, monoethanolamine or ammonium hydrogencarbonate to adjust the pH. Is swelled and softened using a solution-form first agent whose alkalinity is adjusted to 9.6 or less, and then oxidatively fixed with a second agent of a solution containing an oxidizing agent such as bromate or hydrogen peroxide as a main ingredient. Method is used.

In particular, for short and hard hair, which is often seen in men, an iron / perm which forms a wave by heat treatment with a hair styling iron after treatment with the first agent for perm is used.
It is often used because it is effective.

However, when the strongly alkaline first agent acts, the hair swells so much that the proteins, amino acids, and other moisturizing components are destroyed and flow out, resulting in so-called dry hair, which reduces the hair strength and feels. It also has the drawback that the combing becomes bad and peeling of the hairy leather, split ends, and broken hair become remarkable. Further, when a heat treatment such as an iron / perm is applied to the hair, the hair proteins are subjected to heat denaturation, which further damages the hair.

Therefore, methods such as the use of a first alkaline agent having a low alkalinity and ironing treatment at a low temperature have been devised, but all of them have a drawback that wave formation is insufficient and not practical.

[0006]

DISCLOSURE OF THE INVENTION The present invention improves the drawbacks of the above-mentioned conventional first agent for alkaline perm and iron perm so that the hair of the iron is not damaged by the heat of the iron. It is an object of the present invention to provide a first agent for permanent wave having a strong wave forming power.

[0007]

The object of the present invention is as follows.
This can be achieved by the first agent for permanent wave, which contains shellac, a higher alcohol, and a reducing agent.

The shellac used in the first agent for permanent wave of the present invention is a resin secreted by a lacquer worm, which is parasitic on trees, by sucking the sap. It has been added to hair lacquer, lipstick, eyebrow, etc. for the purpose of imparting a sexual function, but shellac is sometimes difficult to dissolve in water,
It has rarely been used in water-soluble products such as permanent waving agents.

On the other hand, the first characteristic of the first agent for permanent wave of the present invention is that the shellac is blended, and the blending amount of the shellac is 0.00
It is preferably in the range of 1 to 1%. The blending amount is 0.
If it is less than 001%, the effect is not sufficient, and if it exceeds 1%, the texture begins to be impaired.

The higher alcohol used in the first agent for permanent wave of the present invention is lauryl alcohol,
One or two selected from higher alcohol groups such as myristyl alcohol, cetanol, cetostearyl alcohol, stearyl alcohol and behenyl alcohol.

The amount of the higher alcohol blended is preferably within the range of 0.5 to 20% in the first agent. If the blending amount is less than 0.5%, the effect is not sufficient, and if it exceeds 20%, the operability of perm treatment is impaired.

The reducing agent used in the first agent for permanent wave of the present invention is one or more selected from thioglycolic acid, thioglycolate, cysteine and athicercysteine. The thioglycolate salt may be ammonium thioglycolate, sodium thioglycolate, potassium thioglycolate, monoethanolamine thioglycolate, triethanolamine thioglycolate, or the like.

The amount of the reducing agent blended is 1 to 7 in the first agent.
It is preferably within the range of%. If the blending amount is less than 1%, the wave-forming power is not sufficient, and if it exceeds 7%, the hair is greatly damaged. The pH of the first agent is 4 to 10
It is preferably within the range. Outside this range, hair and skin damage is increased.

The first agent for permanent wave in the present invention may optionally contain other components, such as a cationic or anionic agent, as long as the effects of the present invention are not impaired.
High molecular weight or low molecular weight surfactant such as amphoteric or nonionic, urea, protein hydrolyzate, amino acid, hair restorer,
Preservatives, pH adjusters, fragrances, pigments, etc. can be added and compounded.

[0015]

The present invention will be specifically described below with reference to examples, but the present invention is not limited to these examples. (Example 1) Thioglycolic acid monoethanolamine (TGmEA-50) containing 50% of thioglycolic acid
), 25% aqueous ammonia (AmOH-25), ammonium hydrogen carbonate (AmCB), guanidine carbonate (GuC)
B), lauryl alcohol (LaOH), cetyl alcohol (CtOH), polyoxyethylene oleyl ether (50E.O.) (POEOE-50), polyoxyethylene lauryl ether (25E.O.) (POELE-25), poly Oxyethylene lauryl ether (9E.O.) (POELE
-9), triethanolamine lauryl sulfate (TEAL
S), hydroxyethyl cellulose (HEC), shellac (S HELC), and triethanolamine (TE
Using A), four types of first agents for permanent wave having the compositions shown in Table 1 were prepared.

[0016]

[Table 1]

Iron and perm treatment was carried out as follows using these first agents. That is, first
The agent was fixed on the root side of hair (Chinese untreated hair) having a length of 8 cm and a weight of 1 g with an adhesive to apply it to a hair bundle having a width of 3 cm, treated at 40 ° C. for 15 minutes, and then washed with water. . Then 1
Using a hair styling iron heated to 80 ° C., a wave was formed, treated with a second agent (sodium bromate 7% solution) for 10 minutes, and then washed with water. Regarding wave forming power and hair damage (touch, gloss), "very good: 5""good:4"
Table 2 shows the results of the five-level evaluation of "ordinary: 3", "bad: 2" and "very bad: 1", and the average value of 10 samples.

[0018]

[Table 2]

From the results shown in Table 2, it can be seen that the addition of shellac to the usual first agent for perm (Comparative Product 3) does not improve the wave-forming power, but on the contrary, it deteriorates the feel. On the other hand, when shellac was added to the first agent for perm (comparative product 1) obtained by emulsifying a higher alcohol with a surfactant, the wave forming power, touch and gloss were significantly improved, and a firm wave was obtained. Almost no hair damage was observed.

Example 2 A first agent for perm having the composition shown in Table 3 and a second agent for perm having the composition shown in Table 4 were prepared.
