Description

Hair-dye composition with microemulsion phase {Hair-dye composition with microemulsion phase}

The present invention relates to a hair-dye composition comprising a microemulsion phase, and more particularly, to a hair-dye composition for reducing off-flavor caused by ammonium or amine alkalizing agents by blending a fragrance into the microemulsion phase.

In general, hair dyes are classified into oxidized hair dyes (permanent hair dyes) and non-oxidized hair dyes (semi-permanent hair dyes) depending on the durability of the colored color and the characteristics of the composition. In the case of the oxidation hair dye used to color the hair, a low molecular weight oxidation dye causes an oxidation polymerization reaction in the hair to form a pigment. Various colors can be obtained by the selection and combination of the oxidation dye. It is the most widely used type of hair dye because of its excellent holding power.

The oxidation-type hair dye composition contains at least one dye precursor and at least one coupler that forms a dye by oxidation by an oxidizing agent.For stability reasons, the hair dye and the oxidizing agent are stored separately and then diluted with a hydrogen peroxide solution immediately before application to the hair. The resulting oxidizing agent is mixed with a hair dye and used.

Usually, in the case of an oxidation hair dye, a combination of an alkalizing agent to increase the pH and an oxidation dye to display color is added to the first agent. The alkalizing agent applied to the first hair dye agent is mainly ammonium or amine compounds such as aqueous ammonia, monoethanolamine, and aminomethylpropanol, and these components may cause discomfort or irritation during dyeing due to the unique odor of amine. Fatty acid derivatives used as raw materials for ignition also have their own raw odor, and dye components are also components with an unsaturated aromatic structure, so their off-odor is strong, and the unpleasant odor persists as part of the hair remains after dyeing. There are many.

In order to improve such an unpleasant off-flavor, a strong fragrance is applied to improve off-flavor, or a large amount of fragrance is applied to block unpleasant odors, but the dissipation power is weak during dyeing, or most are washed off after washing. Therefore, there are many cases where the effect of improving off-flavor is not sufficient.

In particular, the hair dye composition is characterized in that it contains a fragrance in the inner phase of the microemulsion.

The present inventors have studied to reduce off-flavor caused by an ammonium or amine alkalizing agent used in a hair dye and a dye component having an unsaturated aromatic structure. As a result, by miniaturizing the fragrance particles in a microemulsion formulation, the contact surface on the hair surface is enlarged to increase the scent dissipation power, and by improving the adsorption and permeability to the hair surface, the fragrance persists well on the hair surface, resulting in a small amount of fragrance.

Experimental Example 1: Comparison of off-odor (unpleasant odor) of hair dye during dyeing

A panel of 17 people participated in the evaluation to evaluate the off-flavor of the hair dye during dyeing. The evaluation scale of off-flavor masking was 1 when off-flavor was strong, and 5 when off-flavor was not recognized (5-point scale). The evaluation method evaluated the odor perceived at the mouth of the container by discharging the hair dye mixed with the first agent and the second agent in a 500 g container (because the consumer perceives the odor that diffuses into the air, not the hair when using the hair dye). The results of evaluating the off-flavor of the hair dye during dyeing are shown in Table 4 below.

In order to evaluate the color expression when dyeing the hair dye compositions of Examples and Comparative Examples, the hair dye composition was mixed in a pump-type foam container, and then dyed in the form of foam discharged by a pump. A panel of 17 people participated in the evaluation of staining color expression. The evaluation scale was set to 1 as the color clarity was blurred and 5 as the color sharpness (5 point scale). As for the evaluation method, the hair dye mixed with the first agent and the second agent was discharged as a foam, applied to the yakmo tress by hand, left to be dyed for 20 minutes, washed with shampoo and dried, and then the colors were compared.
