Description

TECHNICAL FIELD The present invention relates to a perfume composition for masking the reaction odor generated when hair is treated with a hair-modifying agent containing thioglycolic acid or its salt or derivative thereof.

In recent years, hair modification agents (for example, agents for permanent wave and hair straightening agents) have been widely used as means for changing hairstyles and enjoying them as fashion.
The hair is deformed by the hair modifying agent by winding the hair with a rod, partially cutting the disulfide bonds of the hair keratin with the reducing agent contained in the first agent, and then rebonding them with the oxidizing agent contained in the second agent. , to give waves to the hair, and to straighten unruly hair and transform the hair.
Thioglycolic acid, thiolactic acid, cysteine, cysteamine or a salt thereof or a derivative thereof is used as the reducing agent contained in the first agent of the hair-modifying agent, while the oxidizing agent contained in the second agent is Sodium bromate, potassium bromate, sodium perborate, and hydrogen peroxide are used.

For more than half a century, hair-modifying agents containing thioglycolic acid, salts thereof, or derivatives thereof (hereinafter referred to as "thioglycolic acid, etc.") have mainly been used as reducing agents. Thioglycolic acid and the like are characterized by being easily compatible with oil and easily penetrating into the hair, so that strong waves can be given.
However, when a hair-modifying agent containing thioglycolic acid or the like is applied to the hair, the reaction odor generated is very strong and remains for several days after the application, giving the user an unpleasant feeling. Moreover, when the treatment is performed at a beauty parlor or the like, it is a problem for the operator and surrounding customers.

Deodorization and masking of such unpleasant reaction odors have become important subjects, and various methods have been proposed so far.
Regarding masking when thioglycolic acid or the like is used as a reducing agent, for example, Patent Document 1 describes dimetol, paracresyl acetate, ethyltricyclo[5.2.1.0 ^2,6 ]decan-2-ylcarboxy A permanent wave deodorant composition containing one or more selected from laxate, tricyclodecenyl acetate, 3,3-dimethylcyclohexylmethyl ketone and phenylethyl isoamyl ether has been proposed, and Patent Document 2 (1) A deodorant perfume composition for hair cosmetics has been proposed which uses a combination of chemical deodorant components (aldehydes, formic acid esters and tiglic acid derivatives) and (2) a vapor pressure suppressing component.

Further, in Patent Document 3, acetyldiisoamylene, linalool oxide, rosephenone, 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-buten-1-ol, 3-methyl-5-(2,2,3-trimethyl-3-cyclopenten-1-yl)-pentan-2-ol, 2-ethyl-4-(2,2,3-trimethyl-3-cyclopentene-1 -yl)-2-buten-1-ol, 4-(1-ethoxyvinyl)-3,3,5,5-tetramethylcyclohexanone, cis-p-menthan-7-ol, nerolidol, raspberry ketone, α, 3,3-trimethylcyclohexane methyl formate, para-methoxyphenethyl alcohol, 2,2,6-trimethylcyclohexanecarboxylic acid ethyl ester, 2,6,6-trimethyl-1-crotonylcyclohexane, tansy oil, basil oil A deodorant composition for permanent waving has been proposed, characterized in that it contains a composition comprising at least one compound or essential oil.

Furthermore, Patent Document 4 proposes a permanent waving agent containing at least one deodorant selected from cypress oil and cypress oil.
However, the reaction odor targeted by the technique proposed in the above document is assumed to be the so-called sulfur odor of hydrogen sulfide, sulfides, disulfides, trisulfides, etc., and consideration of the substance itself causing the reaction odor is not possible. had not been done.

In Patent Document 5, regarding the reaction odor when thioglycolic acid or the like is used as a reducing agent, dimethyldiselenide and methylmethylthioselenide, which have collagen-like and gelatin-like odors, are generated during the treatment, and these react with each other. Perfumes have been proposed which have been found to be important as odors and which effectively mask these compounds.
However, the treatment odor generated during permanent treatment is more complicated, and it is difficult to mask it completely. rice field.

As described above, when a hair-modifying agent containing thioglycolic acid or the like is applied to the hair, the reaction odor generated is very strong, and is characteristic in that it remains for several days after the application. Therefore, masking the thioglycolic acid or the like in the hair-modifying agent alone is insufficient, and masking the reaction odor remaining after the treatment is important.
In addition, the causative substances of the reaction odor generated during the treatment have not been identified other than the above-mentioned dimethyldiselenide and methylmethylthioselenide. The current situation is that deodorization or masking that lasts is not achieved.

JP-A-2000-344636 JP-A-2002-241237 Japanese Patent Application Laid-Open No. 2003-277239 JP-A-2006-16333 JP 2015-67558 A

To provide a perfume composition for masking a treatment odor generated when a hair-modifying agent containing thioglycolic acid or the like is applied to the hair, and a residual reaction odor.

As a result of intensive studies, the present inventors have found that when a hair-modifying agent containing thioglycolic acid or the like is applied to the hair, the treatment odor generated and the remaining reaction odor are caused by four compounds, namely propanethiol, 2, Based on 6-dimethylpyrazine, benzothiazole and 2-methylthiobenzothiazole, each was found to be malodorous.

[2] Application of fragrance composition The masking fragrance composition of the present invention can effectively mask the treatment reaction odor of hair transformation agents containing thioglycolic acid or the like by blending with various hair transformation agents or hair cosmetics. can do.
The amount of the perfume composition to be added to the hair transforming agent or hair cosmetic is 0.05 to 5% by mass, preferably 0.07 to 4% by mass, and more preferably 0.1 to 3% by mass.
Examples of hair cosmetics include pre-treatment agents, intermediate-treatment agents, and post-treatment agents containing thioglycol and the like, and shampoos and rinses for damaged hair care.

[Test Example 1] Identification of the causative agent of the treatment reaction odor of hair modification agents containing thioglycolic acid, etc. 15 g of hair bundles were added to 30 g of the first agent containing ammonium thioglycolate, prepared according to the formulation shown in Table 1. (Matai Japan Co., Ltd.), the hair bundle was placed in a desiccator.
Air was sent through activated carbon from the bottom of the desiccator, and a glass tube filled with Tenax-TA (trade name, GL Sciences Co., Ltd.) as an adsorbent was placed at the top.
A pump was used to suck the reaction odor of a hair modification agent containing ammonium thioglycolate at a rate of 500 ml/min for 1 hour. Subsequently, 5 ml of hexane was used to extract the treatment reaction odor adsorbed in the glass tube filled with Tenax-TA.
The resulting treatment reaction odor extract was concentrated using an evaporator.
Next, the resulting treatment reaction odor concentrated solution was analyzed with a gas chromatography mass spectrometer (GC/MS) equipped with a sulfur chemiluminescence detector (SCD) and a gas chromatography olfactometric analyzer (GC-O ) were used for each analysis.

Propanethiol, 2,6-dimethylpyrazine, benzothiazole and 2-methylthiobenzothiazole were detected as a result of analysis with a GC/MS/SCD apparatus.
When the expert panelists confirmed the odor of each of the above four components, it was found that the contribution of the hair-modifying agent containing ammonium thioglycolate to the treatment reaction odor is very high. Table 2 shows the results.
Further, as a result of analysis by GC-O, it was confirmed that the treatment reaction odor concentrated solution and the preparations of the above four components had the same retention time as the treatment reaction odor.
Based on the above results, it was concluded that each of the above four components is the causative agent of the odor caused by the application of a hair-modifying agent containing ammonium thioglycolate.

Propanethiol, which was confirmed by the above analytical results, is known to exhibit an unpleasant sulfurous cabbage-like odor, and has been reported as an odor component of plants belonging to the genus Allium and beef. (Anal. Chem. 54 (1982) 1082; Kuwata et al., J. Agric. Food Chem. 64 (2016) 4299-4311; D. Frank et al.)
The present inventors have confirmed for the first time that propanethiol has not been reported as an aromatic component of the treatment odor generated during the application of a hair-modifying agent containing ammonium thioglycolate.

2,6-Dimethylpyrazine, which was confirmed by the above analytical results, is known to exhibit a sweet roasted aroma and a fried potato-like aroma, and has been reported as an aroma component of asparagus and beef. (J. Agric. Food Chem. 25 (1977) 459-463; R. Tressl et al., J. Agric. Food Chem. 64 (2016) 4299-4311; D. Frank et al.)
2,6-Dimethylpyrazine has not been reported as the aromatic component of the reaction odor that occurs during the treatment of hair-shaping agents containing ammonium thioglycolate and remains for about a day after the treatment, and the present inventors confirmed this for the first time. did.

Benzothiazole, which was confirmed by the above analytical results, is known to exhibit a quinoline-like aroma, and is reported to be an important aroma component in kettle-roasted green tea. (J. Agric. Food Chem., 2002, 50, 5660-5663. Kenji Kumazawa and Hideki Masuda)
The present inventors have confirmed for the first time that benzothiazole has not been reported as an aromatic component of the reaction odor that remains for about 3 days after application of a hair-modifying agent containing ammonium thioglycolate.

2-Methylthiobenzothiazole, which was confirmed by the above analytical results, is known to exhibit a fatty-like, woody-like, and smoky-like aroma, and has been reported as an important aroma component in roasted green tea. (J. Agric. Food Chem., 2002, 50, 5660-5663. Kenji Kumazawa and Hideki Masuda)
The present inventors have confirmed for the first time that 2-methylthiobenzothiazole has not been reported as the aromatic component of the reaction odor that remains for about 3 days after application of a hair-modifying agent containing ammonium thioglycolate.

In fact, after applying a hair-modifying agent containing ammonium thioglycolate to the hair, the reaction odors of propanethiol, 2,6-dimethylpyrazine, benzothiazole and 2-methylthiobenzoate were detected immediately after, 1 day, and 3 days after the treatment. A sensory evaluation of the strength of thiazole revealed that it was extremely strong and that it remained for several days after the treatment.
For this reason, it was found that the persistence and strength of the fragrance are important for the masking fragrances of propanethiol, 2,6-dimethylpyrazine, benzothiazole and 2-methylthiobenzothiazole, which are treatment-reactive odors.

[Test Example 2]
The fragrances shown in Tables 3 to 5 were evaluated for their effect of masking the treatment-reactive odor of hair-modifying agents containing thioglycolic acid and the like.
In the evaluation method, propanethiol, 2,6-dimethylpyrazine, and an equal mixture of benzothiazole and 2-methylthiobenzothiazole were each diluted with dipropylene glycol (DPG) as a reaction odor after treatment with a hair-modifying agent, and the odor was 0.00. A 005% DPG solution was prepared.
A 2% perfume DPG solution was prepared as the perfume to be subjected to the masking test. As the evaluation method, a filter paper was placed in a petri dish, and 0.05 g of DPG solution for each of the reaction odors of hair modification agent application was added, and further 0.05 g of perfume DPG solution was added thereon.

Five expert panelists evaluated the masking effect of the treatment reaction odor on the samples prepared by the above process according to the following four stages. The results are shown in Tables 3-5.
⊚: Complete masking.
◯: Masking is almost completed.
