Description

Composition for hair dyeing and hair dyeing method using the same {COMPOSITION FOR DYEING HAIR AND METHOD FOR DYEING USING THE SAME}

The present invention relates to a composition for dyeing hair and a method for dyeing hair using the same.

Currently used hair dyeing methods include oxidation-type hair dyes called permanent hair dyes because of their high durability, and natural mordants that remain on the surface of the hair in a water-insoluble state and show color by coordination bonds between pigments obtained from plants or tannins and polyvalent metal ions such as iron. Dyeing, direct dyeing such as acidic hair dyes (hair nail polish) that show color by absorbing synthetic pigments called tar colors into hair, and temporary hair dyes that use pigments to temporarily show color and lose color after washing.

Oxidative hair dyes acquire color through the oxidation reaction of dye intermediates that do not show color. Some of the dye intermediates may cause allergic contact dermatitis when used by people with allergic constitutions, and hydrogen peroxide and Skin irritation by the same oxidizing substances may occur. In addition, there is a problem that the possibility of skin irritation is high because the liquid is in an alkaline condition to absorb the dye intermediate in the hair and shorten the dyeing time. In the case of natural mordant dyeing, the durability of the initial color is excellent, but as the pigment remains mainly on the surface of the hair, the softness of the hair is reduced and the feeling of stiffness appears. Acidic hair dyes have less stimulation than oxidative hair dyes because their dyeing mechanism does not depend on chemical reactions, but they have weak dyeability and color durability.

In addition, in the case of dyes using acid dyes, the color is severely eluted, and since the procedure occurs in an acidic environment, it can damage the hair. However, since acidic dyes must be adsorbed to the hair in a maximum amount, the use of raw materials for conditioning (treatment) is limited as much as possible, and thus hair damage is an unavoidable problem.

In order to improve these problems of existing hair dyes, it is necessary to develop hair dyes that use acid dyes but improve dyeability, hair damage mitigation, and fastness.

The first agent may be in a liquid state, and an acidic dye may be dispersed or dissolved in a solvent.

The solvent may be, but is not limited to, water.

The acid dye in the first agent may be included in an appropriate concentration in consideration of the degree of desired color, prevention of hair damage, and the like.

The hair treatment is not particularly limited as long as it is supplied to damaged hair to protect the scalp and hair tissue and to prevent further damage, for example, dimethicone, cetyl alcohol, keratin, collagen, protein, surfactant or moisturizer etc. may be included. In addition, known products can be used for hair treatment.

The second agent may be liquid, and may be a dispersion or dissolution of hair treatment and chitosan in a solvent.

The solvent may be, but is not limited to, water.

Treatment and chitosan in the second agent may be included at an appropriate concentration in consideration of the purpose of preventing hair damage and improving the dyeing effect.

The first agent and the second agent may be included in a weight ratio of, for example, 1:0.5 to 2, 1:0.7 to 1.7, or 1:0.9 to 1.5. It is not limited to the above range, but when included within the above range, the dyeing effect can be improved and hair damage can be alleviated.

The second agent may include, for example, 0.05 to 1 wt %, 0.07 to 0.8 wt %, or 0.09 to 0.5 wt % of chitosan. It is not limited within the above range, but when chitosan is included within the above range in the second agent, the effect of inhibiting the dissolution of dyed hair may be improved.

The second agent may be, for example, a mixture of treatment and chitosan aqueous solution. The aqueous solution of chitosan is, for example, at a concentration of 0.1 to 5% by weight, specifically 0.1 to 5% by weight, 0.1 to 3% by weight, 0.1 to 2% by weight, 0.5 to 2% by weight, 0.5 to 1.5% by weight, or 0.8 to 1.2% by weight.

As a result, it was found that the highest dyeing power was exhibited when the dyeing reaction was performed by mixing the chitosan aqueous solution with the first agent and the second agent.

5. Dyeing effect according to chitosan molecular weight

As in Experiment 3, 2 g of agent 1 containing an acid dye and 2 g of agent 2 not containing chitosan were first mixed, and then distilled water (control) or chitosan having a different molecular weight (100,000 kDa (polymer chitosan), 30 kDa ( The degree of hair dyeing was confirmed by adding 1 g each of 1% chitosan aqueous solution containing low-molecular-weight chitosan)).

The results are shown in FIGS. 8, 9 and Table 4.

Sample control group 30 kDa 100000 kDa L* 64.15±0.03 63.01±0.02 62.26±0.59 a* 62.00±0.49 68.41±0.36 65.89±0.57 b* 43.42±0.32 47.66±0.81 46.90±0.49

As a result, the red value (a*) of the hair mixed with the chitosan aqueous solution was higher than that of the control group, and was the highest when treated with low and medium molecular weight chitosan. These results can be said that medium-low molecular weight chitosan shows higher efficiency in adsorption of pigment.

6. Comparison of hair surface after dyeing reaction

When the surface of the hair dyed with the existing acid dye and the dyeing composition of the present invention (Bio-hCC) is observed, the surface of the hair dyed with the dyeing composition of the present invention is smoother and the cuticle layers are sufficiently smooth.
