Description

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention has an appropriate viscosity so that it can evenly permeate into hair, and can reduce or oxidize hair evenly, and has good storage stability and sagging. The present invention relates to a permanent waving composition which is small in amount, has a reduced viscosity when applied to hair, and can be smoothly applied, so that it can be applied evenly, and is excellent in feeling of use and familiarity with the agent to hair.

[0002]

BACKGROUND OF THE INVENTION Permanent waving agents reduce and oxidize hair to deform it. This reducing and oxidizing action can damage the hair. Therefore, it is necessary to adjust the strength, action time, amount, etc. of the agent so as to obtain an appropriate action. Particularly damaged hair must be treated under milder conditions.

However, even for the same person, the degree of hair damage varies depending on the hair portion. That is, the portion near the hair root is less damaged, and the closer the hair is to the tip, the greater the damage. Therefore, a stronger treatment condition is required for the portion near the hair root, and a gentle treatment condition is required for the tip of the hair.

Even when there is no difference in the degree of damage to the hair near the hair tips and the roots, the hair tips are often caught inside the rod and fixed with paper, so that the agent that permeates the hair quickly. Is used, excess agent retained on the paper causes excessive reduction or oxidation, and the tip portion of the hair is selectively damaged.

Therefore, in order to protect the hair tips, it is necessary to suppress the penetration of the agent into the hair tips. Therefore, agents having an appropriate viscosity have been desired. Further, a substance having an appropriate viscosity evenly penetrates into each part of the hair, so that it prevents unevenness of the wave, and also helps to fix the hair during treatment and prevent the agent from dropping.

Conventionally, as a method for imparting viscosity to cosmetics such as permanent waving agents, there is a method in which a water-soluble polymer is blended or an emulsion is used.

However, when an agent having a viscosity of several hundred centipoises or more is produced by blending only a water-soluble polymer, the agent becomes a gel or becomes sticky, and the fit and spread of the agent on the hair deteriorate. Therefore, the reaction becomes uneven, which causes unevenness of the wave.

On the other hand, the emulsion generally becomes unstable due to the coexistence of a salt, causing destruction of the emulsion system and separation of the system. Particularly in the case of a permanent waving agent, thioglycolic acid or a salt thereof which is a keratin-reducing substance used as a main component, cysteine and / or a derivative thereof or a salt thereof, sulfurous acid or hydrogen sulfite, and bromine which is a keratin-oxidizing substance. Acid salts, hydrogen peroxide, etc. are factors that destroy the emulsion system. In addition to these, high-concentration salts that are added in some cases, for example, salts for forming a strong buffer system, keratolytic agents such as urea, or salts for incorporating polymers, etc., also destabilize the emulsion system. ..

[0009]

Therefore, there has been a demand for a permanent waving agent which is stable in a system in which an oxidizing agent and a reducing agent are present and has an appropriate viscosity.

[0010]

In view of such circumstances, the inventors of the present invention have conducted diligent research and as a result, have found that if an oxidizing agent or a reducing agent is blended with a specific alkyl phosphate ester and a specific alcohol, the stability is improved. It is possible to obtain a permanent waving agent composition having an appropriate viscosity, and when used, it does not cause stickiness, has good elongation, and is well suited to the hair,
