Description

Oxidative hair dye composition

Technical Field

The present invention relates to an oxidative hair dye composition, and more particularly to an oxidative hair dye composition which can significantly improve the pungent odor and unpleasant odor of ammonia by containing a mixture of a higher aliphatic alcohol, a sorbitan-based surfactant, and a glucose-based surfactant as active ingredients.

Background

Generally, hair bleaching agents and hair dyes use oxidizing agents such as peroxides which play a role in bleaching hair, including hydrogen peroxide, urea peroxide, melamine peroxide, and the like. Ammonia is an effective activator, accelerating the bleaching and dyeing action of these peroxides on the hair, i.e. the oxidative destruction of melanin, and increasing the oxidative coupling ratio of the dyes. In addition, in order to effectively act as a hair bleach, the pH needs to be adjusted to be alkaline. Although these pH adjusting effects can be achieved by other alkaline agents, ammonia is the most preferred alkaline agent because it has the advantage of being able to simultaneously and effectively exert both the activating and pH adjusting effects, as well as swelling the hair and facilitating removal of excess parts after dyeing. Because of these effects, ammonia is most commonly used in hair depigmenting or hair coloring agents.

Ammonia, which is a highly volatile alkaline agent, generates an irritating odor peculiar to ammonia when the first and second agents are mixed or applied to hair, and causes irritation not only to eyes and skin but also a very nausea odor, which is very unpleasant to a person.

Other organic/inorganic alkaline agents can be used as a means for relieving the ammonia irritation, but the dyeing effect is not as good as that of ammonia, and the ammonia remains on the hair and scalp to increase the scalp irritation and hair damage, and ammonia is the most widely used alkaline agent. Therefore, reduction of ammonia odor is the most important issue.

As known from the prior art relating to the deodorization of ammonia, epoleon N7C, available from Epoleon corporation of japan, is commercially available, and this Epoleon N7C reduces the source of malodor generation by chemically neutralizing ammonia by mixing an appropriate acid-base component, but when it is used in a hair dye, the content of ammonia itself is finally reduced, which has a problem of hindering the original purpose of using ammonia in the hair dye.

Further, sensory neutralization methods and the like have been disclosed in which odor removal is attempted by adding a suitable combination of a common perfume material or a plant-derived complex extract (see patent document 1: korean patent publication No. 2000-0025753) or peppermint oil as a natural essential oil, and this method has a problem of deterioration of cosmetics because the odor removal effect is relatively weak and extremely high in alkalinity while maintaining the ammonia content in hair dyes, and the stability of perfume components, plant-derived extract components (plant-derived complex extract), natural essential oil components and the like in cosmetics is seriously affected, and therefore, the effect of suppressing and reducing the pungent odor and unpleasant odor of ammonia (hereinafter referred to as "odor removal effect of ammonia odor") is reduced when the cosmetics are stored or used for a long time.

[ test example 1 ] test using a detector tube

An oxidative hair dye composition prepared by mixing 30g of the first agent for hair dye prepared in preparation example 1 and 30g of the second agent for hair dye was charged into a 500-mL flask and left at room temperature for about 30 minutes. Then, an Ammonia detection tube (GASTEC No.3HM Ammonia, GASTEC) was connected to the flask, and a pump was started to suck Ammonia generated from the above-mentioned oxidative hair dye composition. The scale of the color change site was read to measure the amount of ammonia produced by the above-mentioned oxidative hair dye composition.

As a result, as shown in tables 5 to 7 below, it was confirmed that the oxidative hair dye composition comprising the above first hair dye agent and second hair dye agent exhibited a low ammonia production amount when the higher aliphatic alcohol (cetyl alcohol, stearyl alcohol, or cetostearyl alcohol), the sorbitan surfactant (cetearyl olive oleate/sorbitan olive oleate), and the glucose surfactant (C12-20 alkyl glucoside) were contained in the first hair dye agent in a mixed state at a weight ratio of 10. In particular, when the higher fatty alcohol contained in the above-mentioned oxidative hair dye composition was cetostearyl alcohol (dosage form examples 1 to 4), it was confirmed that the amount of ammonia produced was the lowest.

In contrast, higher aliphatic alcohols cannot be satisfied: sorbitan-based surfactant: the case of the mixing ratio of glucose-based surfactant =10 of 1 to 3:1 (comparative formulation examples 1 to 7) showed a high ammonia generation amount. Further, when the content of ammonia contained in the above-mentioned oxidative hair dye composition exceeds 10% by weight based on the total weight of the first part of the hair dye (comparative formulation examples 8 to 9), it was also confirmed that a very high ammonia production amount was exhibited.

Tables 5 to 7 below show NH ₃ The amount of ammonia produced was measured by a measuring tube.

[ TABLE 7 ]

[ test example 2 ] sensory evaluation

For the oxidation type hair dye composition prepared by mixing 30g of the first part of the hair dye prepared in preparation example 1 and 30g of the second part of the hair dye, the deodorizing effect of ammonia odor was evaluated by 15 sensory evaluation professionals (panel), and then the average score was calculated by a 10-point method.

The sensory evaluation criteria are shown in Table 8 below.

[ TABLE 8 ]

Evaluation score	Detection degree of ammonia smell
		0	No smell (complete deodorization)
1.0～2.0	Faint ammonia odor was detected
		2.1～4.0	Slightly faint ammonia odor was detected
4.1～5.0	Detection of weak Ammonia odor
		5.1～6.0	General ammonia odor was detected
6.1～7.0	Detection of strong ammonia odor
		7.1～10	Very strong ammonia was detected (glaring and boring)

As a result, as shown in tables 9 to 11 below, when the higher aliphatic alcohol (cetyl alcohol, stearyl alcohol, or cetearyl alcohol), the sorbitan-based surfactant (cetearyl olive oleate/sorbitan olive oleate), and the glucose-based surfactant (C12-20 alkyl glucoside) were contained in the first hairdye preparation in a mixed state at a weight ratio of 10.5 to 10. In particular, when the higher fatty alcohol contained in the above-mentioned oxidative hair dye composition is cetostearyl alcohol (dosage form examples 1 to 4), the ammonia odor intensity was confirmed to be the lowest.

In contrast, higher aliphatic alcohols cannot be satisfied: sorbitan-based surfactant: the mixture ratios of glucose surfactant =10 to 1 to 3:1 (comparative formulation examples 1 to 7) showed high ammonia odor intensity. Further, when the content of ammonia contained in the above-mentioned oxidative hair dye composition exceeds 10% by weight based on the total weight of the first part of the hair dye (comparative example 8 to 9), it was confirmed that the strength of ammonia odor was very high.

The sensory evaluation results of the ammonia odor intensity are shown in tables 9 to 11 below.
