Description

  The present invention relates to a hair cosmetic, and in particular, has excellent curling hair straightening effect, hair waviness straightening effect, and hair cohesion improving effect, can impart a harshness to the hair as needed, and has high humidity. The present invention also relates to a hair cosmetic which has good sustainability of these effects even under conditions, and has no unnatural feeling after use (such as a feeling of stickiness or stickiness), and does not damage the hair even if it is repeatedly treated.

  Until now, not a few people have trouble with styling caused by curly hair and curly hair, but with the recent generalization of coloring and bleaching, hair damage has progressed, and curling and undulation of hair are corrected. Not only has it become even more difficult, but many problems such as spreading of the hair over time have become common. In addition, with the damage of hair, problems such as a decrease in harshness are increasing.

  In general, straight perm treatment (hereinafter referred to as “perm treatment”) is widely used as a method for correcting (straightening) curled hair. This perm treatment is performed by once cutting the SS bond of the keratin protein in the hair with a reducing agent such as thioglycolic acid, and forcibly transforming the curled hair into a straight shape with a high-temperature hair iron or the like. In this method, the S—S bond is re-bonded by treatment with an oxidizing agent such as potassium.

  Thus, the permanent treatment not only involves a chemical reaction, but the SS bond is not completely restored after the permanent treatment, so that the cuticle located on the hair surface is damaged or peeled off, Degeneration and outflow are inevitable. Therefore, it is not preferable to perform the permanent treatment frequently because it causes serious damage to the hair. Further, if the permanent treatment is further performed on the hair damaged by the coloring treatment or the bleaching treatment, There is a problem that the damage progresses remarkably. In addition, there is a problem that the feeling of elasticity is reduced due to hair damage.

  Regardless of the perm treatment, commercially available hair care agents are used as a method for correcting curled hair and hair undulation, improving hair cohesion, and imparting a firmness to the hair. There is a way. Examples of the hair care agent include those blended with polymers and oils, but in order to achieve a sufficient effect, it is necessary to apply a large amount of polymers or oils to the hair, which may cause problems after use. A natural feel (stiffness, stickiness, etc.) cannot be avoided. In addition, under high humidity conditions such as rain, it is one of the major problems that the effect of straightening hair, the effect of correcting hair waviness, and the cohesiveness of hair are significantly reduced in a short time.

In order to solve such problems, an attempt is made to permeate a specific organic acid into the interior of the hair and to continuously improve the hair itself, to provide a correction of curly hair and a feeling of harshness, regardless of the perm treatment. (See Patent Documents 1 to 8).
However, the specific organic acids disclosed in these documents are still not effective in imparting the effect of straightening hair and irritating, and it is necessary to use in combination with a permanent agent or to tighten the processing conditions in order to achieve a sufficient effect. And hair damage due to treatment is inevitable.

In addition to the above, it has also been reported that a specific organic carboxylic acid or organic sulfonic acid is allowed to penetrate into the inside of the hair to cause a drooling hair straightening effect (see Patent Document 9).
However, it is excellent in all of the effects of straightening hair, correcting the waviness of hair, improving the cohesiveness of hair, and imparting a harshness to hair, and the sustainability of these effects is good even under high humidity conditions. In addition, hair cosmetics that have no unnatural feeling after use (such as stickiness, stickiness, etc.) and that do not damage hair even after repeated treatments have not yet been provided, and prompt provision is required. This is the current situation.
