Description

Hair dye composition comprising surfactant derived from nature {Hair coloring composition comprising surfactant obtained from a nature source}

Disclosed herein is a hair dye composition comprising cetearyl olivate, sorbitan olivate, and a colorant as active ingredients, and cetearyl olivate and sorbitan olivate in a weight ratio of 1:0.01 to 3.

Recently, as modern people's interest in beauty has increased, cosmetics with various related functions are being developed and released. Hair dyeing is one of the immediate and certain beauty methods for expressing one's individuality and seeking change, and for this reason, hair dyeing in modern society is becoming popular regardless of age and gender.

Types of hair dyes commonly used for hair dyeing can be broadly divided into oxidized dyed hair and non-oxidized dyed hair depending on their chemical properties. At this time, in the case of oxidized-type hair dyeing, the dyeing effect is superior to non-oxidizing-type hair dyeing, and the color lasting effect is excellent. However, products for dyeing dark colors require an excessive amount of synthetic surfactant for the stability of the formulation, and although the synthetic surfactant is effective, it has a major disadvantage in that it can cause skin irritation and hair damage.

Accordingly, the present inventors attempted various studies to develop a hair dye composition with excellent formulation stability and spreadability without significant skin irritation or hair damage. As a result, cetearyl olivate and sorbitan olivate were mixed at 1:0.01 to 3 weight. The present invention was completed after confirming that the composition contained in the ratio shows excellent hair dyeing properties, causes less damage to the skin or hair, and ensures spreadability and formulation stability.

The hair dyeing effect was determined by applying 6 g of the contents of Examples 1 to 6 and Comparative Example 1 prepared in 1-1 above to white hair, leaving it for 30 minutes, treating it with shampoo, drying it with a dryer, and observing it with the naked eye. Labscan XE (HunterLab It was measured using a (manufactured) machine. The results are shown in Table 2. The lower the measured L value, the darker the staining.

ANDOVER) device. did. The results are shown in Table 2. The lower the measurement value, the less friction it has, indicating a smoother application.

The effect of improving dye dispersion was confirmed through the stability of the contents of Examples 1 to 6 and Comparative Example 1 prepared in 1-1 above by temperature. The temperature was set to 30°C, 45°C, and 50°C, and changes in the stability of the formulation were confirmed over 2 weeks. The results are shown in Table 2.

As can be seen in Table 2, the hair dyeing effect was good in Examples 2 to 4 and 6, and among them, the hair dyeing effect was the best in Example 6, where the ratio of sorbitan olivet to cetearyl olivate was closest to 0.66. The dyeing effect was confirmed. In addition, it was confirmed that the examples in which the hair dyeing effect was good also had excellent dispersibility at high temperatures. This indicates that the ratio of sorbitan olivate to cetearyl olivate has a significant effect on the effectiveness of the hair dye composition.

2. Preparation of Examples 7 and 8 and confirmation of their properties

2-1. Preparation of Examples 7 and 8

Hair dye compositions of Examples 7 and 8 were prepared by varying the content of hydroxy ethyl cellulose. Specifically, among the compositions (unit: weight %) shown in Table 3 below, first, antioxidant, chelating agent, reducing agent, dye, and hydroxy ethyl cellulose were dissolved in deionized water at room temperature, and then wax, oil, shea butter, Cetearyl olivate, sorbitan olivate, and monoethanolamine were added and thoroughly stirred to prepare the hair dye compositions of Examples 7 and 8.

As shown in Table 4, the composition prepared by increasing the content of hydroxy ethyl cellulose from 0 to 0.5% by weight had increased dispersibility at high temperature in proportion to the increase in the content of hydroxy ethyl cellulose. However, although not shown in the table above, as a result of experiments conducted by the present inventors, when the content of hydroxy ethyl cellulose exceeded 0.5% by weight, the viscosity increased excessively, making formulation formation difficult. These results indicate that the addition of hydroxy ethyl cellulose and its content significantly contribute to the dispersibility of the hair dye composition.

2-3. Example 8 Confirmation of hair cuticle damage caused by the composition

The cuticle of dyed hair was observed to confirm the difference in the degree of hair damage between chemical surfactants and natural surfactants during the dyeing process. Specifically, 6 g of the composition of Example 8 was applied to white hair, left for 30 minutes after completion of dyeing, shampooed, dried, and then dyed using a 3D MEASURING LASER MICROSCOPE OLS40-SU (OLYMPUS) device. The degree of damage to the simulated cuticle was confirmed. As a control, the cuticle damage of dyed hair treated with the composition of Comparative Example 1 instead of Example 8 was also confirmed. The results are shown in Figure 1.

As shown in Figure 1, unlike hair dyed with the composition of Comparative Example 1 containing a chemical surfactant, cuticle damage occurred in hair dyed with the composition of Example 8 containing a naturally derived surfactant. It was confirmed that it was relatively small. This indicates that the composition of the present invention using a naturally derived surfactant is a hypoallergenic material and has excellent usability as a hair dye composition.
