Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the removal of unpleasant hair odors caused by the use of permanent waving agents containing mercapto compounds.

0002

2. Description of the Related Art Conventionally, waving treatment using the permanent wave method is performed using a first agent containing a reducing agent and a second agent containing an oxidizing agent. As the reducing agent of the first agent, thioglycolic acid or a salt thereof, or a mercapto compound such as cysteine is used.

[0003] Hair treated with a permanent waving agent using this mercapto compound retains a mercaptan odor characteristic of a permanent waving agent, which cannot be removed even after shampooing several times. This was especially noticeable when sweating, and the subject was made to feel extremely uncomfortable.

[0004] The cause of the residual odor caused by this permanent waving treatment is that the mercapto compound in the permanent waving agent quite strongly adsorbs to hair keratin, and is not completely removed by rinsing with water.
This is also due to the fact that free -SH groups in the hair generated during permanent waving are decomposed into hydrogen sulfide and mercapto compounds such as methyl mercaptan.

[0005] As a method of eliminating such an unpleasant odor after the permanent wave treatment, there is a so-called masking method in which a strong fragrance is added to the composition to make the unpleasant odor not perceptible. However, with the masking method, it is generally impossible to completely remove unpleasant odors, and the fragrance persists in the hair, which is often disliked by some people in terms of palatability.

[0006] For this reason, attempts have been made to incorporate deodorizing ingredients into permanent waving agents, but conventional deodorizing ingredients (terpenes, etc.) are not able to alleviate unpleasant odors to some extent. However, the odor of the deodorant itself remained, which was not always satisfactory.

Furthermore, these active ingredients react with the reducing agent in the permanent waving agent and reduce the reducing power.
In other words, there was a problem in that the wave forming force was reduced.

[0008]

[Problems to be Solved by the Invention] In view of the above circumstances, it is an object of the present invention to completely eliminate the unpleasant odor of hair caused by the use of a permanent waving agent containing a mercapto compound, without reducing the waving ability. An object of the present invention is to provide a deodorizing composition for permanent waves that removes odors.

[0009]

[Means for Solving the Problems] The present invention is a deodorizing composition for permanent waves, which is characterized by containing at least one of hydrophilic organic solvent extracts of hops, scutellariae, aloe, and butcher bloom. .

[0010] The deodorizing composition for permanent waves of the present invention will be explained in more detail below.

[0011] The specific plants used in the present invention include hops (Humulus lupulus), Scutellaria baicalen (Scutellaria baicalen)
sisGeorgi), Aloe barb
adensis), butcher bloom (Rusucu)
s aculeatus L. ), and generally the female panicles (cones) are used for hops, the leaves for aloe, the roots for scutellariae, and the rhizomes for butcher bloom.

Hydrophilic organic solvents are used as extraction solvents for these plants. As the hydrophilic organic solvent, methanol, ethanol, polyhydric alcohol, acetone, etc. are used.

[0013] The extraction method is not particularly limited as long as the extraction solvent described above is used, but it can be carried out, for example, as follows.

Hydrophilic organic solvents such as alcohols such as ethanol and methanol, and ketones such as methyl ethyl ketone and acetone are added to the raw material plant, and the active ingredients are thermally extracted using a Soxhlet extractor or the like. The extraction operation may be performed using a mixture of a hydrophilic solvent and water.

The extract thus obtained may be subjected to a rotary evaporator or a vacuum dryer to remove water or a hydrophilic solvent, and then used as a concentrated solution or solid.

[0016] Furthermore, the obtained solvent extracts of plants can be used alone or in combination of two or more.

[0017] The extraction is not a single-stage extraction as described above,
If necessary, a hydrophobic organic solvent may be used to elute and remove odor components from the raw material plant in advance.

[0018] Alternatively, a steam distillation method may be used.

As another method, it is also possible to use an extract obtained by extracting the raw material plant with the above-mentioned specific solvent and fractionating it using adsorption chromatography such as silica gel chromatography.

[0020] In the present invention, the content of plant solvent extracts such as hops is calculated based on the total amount of the deodorizing composition for permanent waving in terms of the dry residue of each extract, and is 0.
The amount is preferably 0.001 to 5.0% by weight. 0.00
If it is less than 1% by weight, the effect cannot be expected much even if it is blended, and if it exceeds 5.0% by weight, it is not preferable in terms of the manufacturing process of the product.

[0021] In addition to the above-mentioned essential ingredients, the deodorant composition for permanent waves of the present invention may contain, if necessary, any commonly used ingredients within the range that does not impair the effects of the present invention. Aqueous type, alcohol type,
It can be adjusted to an appropriate form such as emulsion type, stick type, spray type, foam type, etc.

[0022] Specific examples of compositions include shampoos, hair rinses, hair treatments, hair creams, hair lotions, hair tonics, hair sprays, perming agents, and any other compositions used for hair.

This embodiment is used during the permanent wave treatment (between the first agent treatment and the second agent treatment) or after the permanent wave treatment.

[0024]

Effects of the Invention The deodorizing composition for permanent waving of the present invention removes the unpleasant odor of hair caused by the use of a permanent waving agent without reducing the waving ability, and its effects are as follows: It has excellent effects not found in conventional compositions and has extremely high commercial value.

[0025]

[Examples] The present invention will be explained in more detail with reference to Examples below. Test Examples 1 and 2 are a test on the residual amount of mercaptan in hair, a residual odor test, and a wave forming force test. Note that the present invention is not limited to this. Also,
