Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvements in hair dye compositions, especially oxidative hair dye compositions.

[0002]

2. Description of the Related Art Oxidative hair dyes are the most widely used permanent hair dyes. The oxidation dye in the hair dye penetrates into the hair, undergoes oxidative polymerization, and develops color to cause hair to grow. The feature is that the hair dyeing effect lasts because it is chemically dyed.
As the dosage form of the oxidative hair dye, there are a one-part type that is a powder agent mixed with water at the time of use and a multi-part type of three or more agents. The most common type is the two-part type, which is used by mixing with the second part before use. In any case, the oxidative hair dye chemically dyes the hair by an oxidative polymerization reaction. This oxidative polymerization is a fairly vigorous reaction, and uneven application of the oxidative hair dye to the hair may cause uneven dyeing. In order to eliminate this uneven dyeing, it is important that it can be applied quickly and evenly when applied to the hair.Therefore, the oxidative hair dye is provided as a highly fluid liquid by blending various solvents, dispersion media, etc. It had been.

[0003]

However, in such a liquid having high fluidity, the hair dye drips from the hair during or after the hair dyeing treatment, and adheres to the skin or clothes or flows down the face. There was such a problem as On the other hand, if an attempt is made to increase the viscosity of the hair dye by using a thickener or the like so that the hair dye does not sag, the conventional thickener is poor in the spreadability, coatability, and levelness of the oxidative hair dye on the hair. Further, there is a problem that the dyeing property is deteriorated because the thickener inhibits the permeability of the oxidation dye into the hair.

Further, there is a problem that hair after dyeing with an oxidative hair dye is easily dry and lacks in smoothness. The present invention has been made in view of the problems of the prior art as described above, and an object thereof is usability such as extensibility and applicability in spite of no dripping of the hair dye during hair dyeing treatment. The object of the present invention is to provide an oxidative hair dye composition which has good dyeing property, has no uneven dyeing and is excellent in level dyeing property, has good dyeing property of an oxidative dye, and has a good feeling after use.

[0005]

It is characterized by containing one or more kinds. The constitution of the present invention will be described in detail below.

First, the sugar derivative according to the present invention is an ether bond product of a sugar hydroxyl group and a branched aliphatic hydrocarbon group,
In particular, an ether bond of a hydroxyl group other than hemiacetal hydroxyl groups of sugar (non-hemiacetal hydroxyl group) and a branched aliphatic hydrocarbon group is a sugar branched aliphatic ether, a hemiacetal hydroxyl group of sugar and a branched aliphatic hydrocarbon group. An ether bond with (which forms a so-called glycoside bond) is called a branched aliphatic glycoside.

The sugar derivative used in the present invention is represented by the above general formula 4, wherein A is a residue obtained by removing n hydroxyl groups from the sugar, and such sugars include glucose, galactose, Xylose, fructose, altrose,
Monosaccharides such as talose, mannose, arabinose, idose, lyxose, ribose, and allose, and mixtures thereof, maltose, isomaltose, lactose, xylobiose, kentiobiose, cordiobiose, cellobiose, sophorose, nigerose, sucrose, melibiose, laminaribiose.

In the present invention, one kind or two or more kinds of the oily components can be optionally used. The blending amount of the oily component is 0.0 with respect to the total amount of the hair dye composition.
1 to 15.0% by weight is suitable. If the compounding amount of the oily component is less than 0.01% by weight, a sufficient effect cannot be obtained, and
When it is blended in an amount of more than 15% by weight, the level dyeing property, the dyeing property, and the washing resistance are adversely affected, and stickiness may occur to deteriorate the usability.

Examples of the oxidizing agent used in the present invention include hydrogen peroxide, persulfate, perborate, bromate, periodate, urea peroxide and the like. The blending amount of the oxidizing agent is not particularly limited as long as it is within the range generally used for oxidizing hair dyes. The oxidative hair dye composition according to the present invention has an appropriate viscosity such that it does not drip or flow, and is characterized in that it can be applied to hair quickly and evenly and the dyeing is even. The sugar derivative according to the present invention does not prevent the oxidation dye from penetrating into the hair and dye it, and acts together with the oil component to satisfactorily dye the oxidation dye, and the hair after dyeing is smoothly finished. Furthermore, the sugar derivative of the present invention is an acid,
It also has the characteristics that it is stable without being decomposed even in alkali, has no sensitizing property or irritating property even when incorporated into a hair dye composition, and is excellent in safety.

The hair dye composition may contain lower alcohols such as ethanol and isopropanol. When a surfactant is used as a thickener in such a system, the thickening effect is remarkably reduced. Therefore, it is necessary to add a large amount of a surfactant, and problems such as irritation and inhibition of dyeing property tend to occur. If the sugar derivative according to the present invention is used, a thickening effect can be obtained with a small amount even in such a system.

The dosage form of the oxidative hair dye of the present invention is a multi-part formulation of two or more agents. In particular, a sugar derivative and an oily component are mixed with the first agent containing an oxidative dye, and the oxidant is included. One or two or more agents other than the first agent are mixed at the time of use. In this way, by adding the sugar derivative, the oily component and the oxidative dye to the first agent, the feeling of use such as smoothing of the hair after dyeing is greatly improved, and the dyeing property and resistance of the oxidative dye are improved. The synergistic effect that the detergency is significantly improved is exhibited. The synergistic effect is that the oil component is mixed with the sugar derivative and the oxidation dye in the first agent,
What is exhibited in an oxidative dye composition obtained by mixing with another agent containing an oxidative dye at the time of use, for example, a first agent containing a sugar derivative and an oxidative dye, and a first agent containing an oily component and an oxidant. Such a synergistic effect is not exhibited in the oxidizing composition obtained by mixing the two agents at the time of use. The reason for this is not clear, but if an oily component was previously mixed with the sugar derivative and the oxidative dye in the first agent, some interaction occurred between the oily component, the sugar derivative and the oxidative dye, which caused the dyeing property. It is thought that this will bring about an improvement in cleaning resistance. On the other hand, when the oily component is not previously blended with the sugar derivative and the oxidative dye, the interaction as described above cannot occur in advance, and even when the oily component is mixed at the time of use, due to the influence of other components, Since it is difficult to strongly form such an interaction, it is presumed that a synergistic effect may not be exerted on the dyeing property and the like.

Further, the multi-component hair dye composition of the present invention is excellent in product stability, and the sugar derivative also has a surfactant effect even if it does not contain an emulsifier, a dispersant, a solubilizer and the like. Since it has, it also has a feature that the oily component can be uniformly emulsified or dispersed. When the hair dye composition of the present invention is, for example, a two-component composition, the mixing ratio of the first agent and the second agent is usually 1: 1 by weight: 2 by 1: 1. Often, it is not particularly limited as long as there is no inconvenience in dripping, usability, level dyeing property, smoothness, dyeing property, cleaning resistance, and the like.

[Hair dyeing test] An oxidative hair dye composition obtained by mixing the respective first agents of the above-mentioned formulation examples 1 and 2 and comparative examples 1 and 2 with the second agent a in a weight ratio of 1: 1. Was used to carry out a hair dyeing test. Table 3 shows the properties before and after mixing and the results of the hair dyeing test.

As can be seen from Table 3, the first agent (formulation examples 1 and 2) in which the sugar derivative and the oily component (isopropyl myristate) were used in combination was in the form of gel, and even after mixing with the second agent a. Whereas the conventional thickener (Emarex OP
The first agent using (-5) (Comparative Example 1) or the first agent (Comparative Example 2) in which an oily component is used in combination is liquid and remains liquid after mixing with the second agent a. It was difficult and uneven. In addition, in the hair dyeing test, any of the oxidative hair dye compositions using the first agent of Formulation Examples 1 and 2 dripped,
There was no runoff, and the extensibility and application to hair were good, and the leveling properties and the smoothness after dyeing were excellent.
On the other hand, since the mixtures of Comparative Examples 1 and 2 using the conventional thickener were liquid, they had problems such as dripping and runoff, poor levelness and smoothness.

Comparative Examples 3 to 5 Using the samples of Table 4, the first agent (Comparative Examples 3 to 3) in which only the sugar derivative or the oil component was blended in the same formulation as in the above Formulation Examples 1 and 2

As can be seen from Table 5, when the sugar derivative and the oily component (isopropyl myristate) were used in combination (Formulation Examples 1 and 2), gel hair dye compositions were obtained and there was no dripping. Good spreadability / applicability to hair and level dyeability. It was also excellent in dyeing property and wash resistance. Furthermore, the hair after dyeing was very smooth and had an excellent feeling of use. On the other hand, when only the sugar derivative was blended (Comparative Examples 3-4), the properties, sagging, extensibility
Although there is not much difference in coating property and level dyeing property, dyeing property, washing resistance,
The smoothness after dyeing was poor.

When only the oily component was blended (Comparative Example 5), the obtained hair dye composition was in a liquid state and was evaluated in any of the hair dyeing test, the dyeing property test and the washing resistance test. It was extremely inferior. From the above, it is understood that the effects of the present invention are synergistically obtained when a sugar derivative and an oily component are used in combination.

Formulation Examples 3 to 6 and Comparative Examples 6 to 7 Using the samples of Table 6, a first agent was prepared in the same formulation as in the formulation examples 1 and 2, and the weight ratio to the second agent was 1: 1. An oxidative hair dye composition was obtained by mixing.

As can be seen from Table 6, when the oily component is less than 0.01% by weight with respect to the hair dye composition (Comparative Example 7), the smoothness, dyeing property and washing resistance are insufficient. 1
When it exceeds 5% by weight, the level dyeing property, the dyeing property, and the washing resistance tend to be rather deteriorated, and stickiness is felt in use. From the above, the blending amount of the oily component in the oxidative hair dye composition of the present invention is preferably 0.01 to 15% by weight.

Formulation Examples 7 to 9 and Comparative Examples 8 to 10 Using the samples of Table 7, a first agent was prepared in the same formulation as in the formulation examples 1 and 2, and the weight ratio to the second agent a was 1: 1. To obtain an oxidative hair dye composition.

As can be seen from Table 7, in the formulation examples 7 to 9 containing the sugar derivative of the present invention, gel-like oxidative hair dye compositions can be obtained, but when the fatty chain is linear (comparison In Example 8) or when the total number of carbon atoms in the branched fatty chain was less than 18 (Comparative Example 9), the hair dye composition was liquid and did not form a gel. Moreover, when the total number of carbon atoms in the branched fatty chain was greater than 32 (Comparative Example 10), the branched hair chains were separated and a uniform hair dye composition could not be obtained. Further, in the hair dye composition using Formulation Examples 7 to 9, any evaluation was excellent in the hair dyeing test, but the hair dye composition using the first agent of Comparative Examples 8 to 9 was liquid. In addition, the compounding examples 7 to 9 of the present invention are excellent in extensibility / applicability, levelness and smoothness.
