JPS5914002B2 - Hair treatment composition - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hair treatment composition, and more specifically, when it is applied to hair, it protects the hair and provides good feel, texture, flexibility, combability, and This invention relates to an improved hair treatment composition that can provide smoothness and fraying properties.

Many treatment agents have been developed for the purpose of softening hair, but none have been found to be fully satisfactory in terms of texture after washing, ease of fraying, ease of combing, etc.

As a result of extensive research in an effort to overcome all the drawbacks of the conventional art, the present inventor has discovered a method containing a specific oxyamine-based quaternary ammonium salt represented by the general formula below, dried egg white, a humectant, and water. Furthermore, the composition containing a nonionic surfactant and an oily substance exhibits a good protective effect and long-lasting antistatic ability on the hair, and also has excellent texture, flexibility, feel, and combability. The present invention has been completed by discovering that it provides a smooth feeling and fraying property.

An object of the present invention is to provide an improved hair treatment composition that can provide hair with excellent softness, texture, combability, slipperiness, and fraying properties during and after use. There is a particular thing.

That is, the present invention provides the following - Crotch 1) (In the formula, R is an alkyl group having 10 to 18 carbon atoms, R' is a methyl group or an ethyl group, R' is a methyl group, and X is a chlorine atom or a bromine atom. .

) 1 to 5% by weight of a quaternary ammonium salt represented by
This hair treatment composition contains 1 to 5% by weight of dried egg white, 2 to 6% by weight of a humectant, and 83 to 90% by weight of water.

The quaternary ammonium salt of the general formula (1) (oxyamine-based quaternary ammonium salt) has an OH group at the β-position compared to conventional quaternary ammonium salts, and has excellent antistatic ability, durability, and water resistance. It has excellent chemical stability, etc., and its effects are clearly significantly superior when comparing the comparative examples described below with the examples of the present invention.

Further, among the quaternary ammonium salts of general formula (1), more preferred are quaternary ammonium salts (compounds) represented by general formula (2).

The quaternary ammonium salt of general formula (1) used in the present invention has a melting point of about 50 to 70°C, is easily soluble in alcohols, chloroform, toluene, and kerosene, and is relatively sparingly soluble in water. , the liquid has high surface tension and foaming power.

Therefore, it has good permeability to the hair and can be applied easily and uniformly, and is relatively hydrophobic and has a strong antistatic ability, so it can provide the effect of durability.

Although the solubility varies slightly depending on the compound, it is relatively low, so it may be dissolved and mixed in a small amount of alcohol.

The amount of the quaternary ammonium salt used is 1 to 5% by weight, preferably 3 to 4% by weight, based on the weight of the composition.

If it is less than 1% by weight, the antistatic effect and softening effect will be reduced, and it will be difficult to obtain a favorable texture (and the combing will be difficult).

Moreover, even if it is used in an amount exceeding 5% by weight, the effect will not change and it is not economically preferable.

Among the above-mentioned quaternary ammonium salts, those in which k and ``in the general formula are both methyl groups and X is a chlorine atom are particularly preferred in terms of usability, effectiveness, economy, etc.

Dried egg white is a powdery dried product produced by spray-drying raw egg white and then sterilizing it at low temperature, and is easily soluble in water.

Dried egg white can be applied to all known and commercially available products, and has significantly superior effects compared to the use of proteins such as raw egg white.

The amount used is 1 to 5% by weight, preferably 2 to 3.5% by weight, based on the weight of the composition.

If it is less than 1% by weight, the slippery feeling of the hair tends to decrease (,
If the amount is more than 5% by weight, the hair after treatment (finishing) will become stiff and the texture will change.

The term "humectant" refers to all moisturizing agents for cosmetics, and examples thereof include, but are not limited to, glycerin, propylene glycol, 1,3-butylene glycol, hexylene glycol, and the like. It is possible,
Of course, one type or two or more types may be used in combination.

The amount used is 2 to 6% by weight, preferably 2 to 5% by weight, based on the weight of the composition.

If it is less than 2% by weight, the hair will feel dry,
If the amount is more than 6% by weight, it will tend to become sticky after finishing, resulting in a change in feel (and the water resistance will also tend to decrease).

The amount of water is generally 83-90% by weight in balance.

In the present invention, as described above, a good composition can be obtained by containing (mixing) an oxyamine quaternary ammonium salt represented by the general formula, dried egg white, a humectant, and water.
Furthermore, when an oily substance and a nonionic surfactant are mixed and used in combination, it is made oily to improve the hair protection effect, provide a hair styling effect and appropriate viscosity, and further facilitate hair treatment. I can do it.

As the oily substance, higher alcohols, liquid hydrocarbons, etc. are particularly preferred.

In addition, all types of non-in surfactants for cosmetics can be used, such as polyoxyethylene higher alcohol ether of higher alcohols having 12 to 20 carbon atoms, glyceryl monomers of higher fatty acids having 16 to 18 carbon atoms. Particularly preferred examples include fatty acid esters.

Examples of liquid hydrocarbons include liquid paraffin, stanrane, pristane, hydrogenated polyisobutylene, hydrogenated polyisoprene, polymerized octene-1, and dodecene.
Polymer of 1, liquid polyisobutylene, 2.6.15.1
9,23-hexamethyltetracosane and the like are preferred.

The amount of oily substance used is 1.0 to 5% by weight, preferably 2 to 3.5% by weight, based on the weight of the composition.

If it is less than 1.0% by weight, it will be difficult to obtain a suitable feel.
When the amount exceeds 5% by weight, the oily feeling and sticky feeling tend to become stronger.

The amount of nonionic surfactant used is 0.2 to 1% by weight, preferably 0.4 to 0.8% by weight.

If it is less than 0.2% by weight, it is difficult to obtain a stable emulsion (
If the amount exceeds 1%, the viscosity tends to be too high, and the thixotropy and feel tend to deteriorate.

Although the method for producing the hair treatment composition of the present invention is not particularly limited, for example, in the composition containing the quaternary ammonium salt, dried egg white, a humectant, and water, for example, the quaternary ammonium salt, dried egg white, It is obtained by mixing a humectant, a fragrance, and water, heating and dissolving the mixture, and then mixing a homogeneous mixed solution of a coloring agent, a preservative, and water with this mixed solution.

In addition, in the composition containing the quaternary ammonium salt, dried egg white, a humectant, water, an oily substance, and a nonionic surfactant, the quaternary ammonium salt, an oily substance, a nonionic surfactant, and a humectant are mixed. After melting, an aqueous solution of a coloring agent, a preservative, etc. is mixed into this mixed melt and emulsified.

Next, a flavoring agent and further dried egg white are added and mixed to this emulsion.

The hair treatment composition of the present invention is in the form of a uniform transparent liquid or emulsion liquid, has excellent storage stability, protects hair when treating or (applies) hair, and provides a durable and highly Possesses anti-static ability and feels good during and after use.
This is an improved hair treatment composition capable of imparting and exhibiting excellent flexibility, texture, combability, slipperiness, and fraying properties to hair, and its commercial value is extremely high.
