Description

[Detailed description of the invention] Industrial applications The present invention provides a hair treatment composition with excellent transparency.

More specifically, the present invention relates to a gel-like hair rinse agent composition that has excellent transparency, provides an effective feel to the hair, and is temperature-stable.

BACKGROUND OF THE INVENTION Hair is usually covered with sebum secreted from the scalp, hair oil, animal and vegetable oils contained in hair treatment agents such as hair creams, and is protected from mechanical stimulation by combs and brushes. However, if you wash your hair with 9 soap or shampoo.

These oil and fat components are removed more than necessary.

As a result, the hair becomes smooth and curly.

It gives a dry, hard feeling and makes it difficult to comb through, leading to the risk of split ends, hair clippings, and damage to the hair. This is particularly noticeable when the hair has been subjected to chemical treatments such as cold waving or hair dye.

Conventionally, various hair treatment agents have been developed in order to eliminate such inconveniences. For example, such hair treatment agents include quaternary ammonium salts such as dialkyltrimethylammonium chloride and alkyltrimethylammonium chloride as the main ingredients, and oily substances such as liquid paraffin, squalane, methylpolysiloxane, and isopropyl myristate. A hair treatment agent containing the following is used. Such hair treatment agents are generally dissolved or dispersed in hot water, and this liquid is used to rinse the hair.

However, in order to treat hair with the hair treatment agent more effectively, it is preferable to apply the hair treatment agent directly to the hair. In this case, it is necessary to have a considerable viscosity so that no dripping occurs.

By the way, general hair treatment agents have a transparent type and an opaque type in terms of appearance, and the form differs depending on the ingredients, depending on the hair type, etc.

Conventionally, transparent hair treatment agents require a thickener to be applied directly to the hair, and water-soluble polymers such as hydroxyethylcellulose and hydroxypropylmethylcellulose have been used.

However, the problem to be solved is to make a transparent gel-like hair treatment agent such as hydroxyethyl cellulose.

If a large amount of a water-soluble polymer such as hydroxypropyl methylcellulose is added, the rinsing effect is significantly impaired, while if the amount is too small, a sufficient thickening effect cannot be obtained.

Means for Solving the Problem The present inventors focused on the above points and as a result of intensive research, by blending a specific quaternary ammonium salt and the compound described in [2] below, it was found that It has a viscosity that allows it to be applied directly to the hair.

The present inventors discovered that a transparent gel-like hair treatment agent with a rinsing effect can be obtained and completed the present invention.

That is, the present invention is as follows.

General formula [1]: Two are linear or branched alkyl groups and alkenyl groups having 8 to 22 carbon atoms or hydroxyalkyl groups having 8 to 22 carbon atoms; the remaining are alkyl groups having 1 to 3 carbon atoms or carbon atoms 1 to 3 hydroxyalkyl groups; X represents a halogen atom. ] One or more quaternary ammonium salts.

and General Formula [2]: %Formula % [In the formula, +R5 means a linear or branched alkyl group having 10 to 26 carbon atoms, an alkenyl group, or a hydroxyalkyl group, and n means an integer of 1 to 5. ] This is a transparent gel-like hair treatment composition characterized by containing one or more kinds of compounds.

5 Below, the structure of the present invention will be explained in detail. 9 Representative examples of the quaternary ammonium salt represented by the general formula [1] according to the present invention include cetyltrimethylammonium chloride,
Stearyltrimethylammonium chloride, behenyltrimethylammonium chloride, hydrogenated tallow alkyltrimethylammonium chloride, distearyldimethylammonium chloride, distearyldimethylammonium chloride, dilinear alkyl-bis-
(2-hydroxyethyl)ammonium chloride, monolinear alkylpentaethoxylated ammonium chloride, dilinear alkylpolyethoxylated ammonium chloride, etc., and any one or more of these may be used. selected and used.

The blending amount is 1 to 30 in the total amount of the hair treatment composition of the present invention.
Weight%.

Representative examples of the compounds represented by the general formula [2] of the present invention include monoglyceryl dodecyl ether, diglyceryl dodecyl ether, triglyceryl dodecyl ether, tetraglyceryl dodecyl ether, and diglyceryl oleyl ether.

Triglyceryl oleyl ether, diglyceryl isostearyl ether, triglyceryl stearyl ether, diglyceryl dodecyl octyl ether, triglyceryl dodecyl octyl ether.

Examples include diglyceryl nonylphenyl ether, triglyceryl nonylphenyl ether, and any one or more of these may be selected and used.

The blending amount is 2 to 40% of the total amount of the hair treatment composition of the present invention.
Weight%.

The total amount of the quaternary ammonium salt represented by the general formula [1] and the compound represented by the general formula [2] is 4 to 45% by weight based on the total amount of the hair treatment composition of the present invention.

Preferably it is in the range of 8 to 30% by weight.

Even if the composition falls outside of any of the above ranges,
It is undesirable because it exhibits no gel properties and is difficult to apply in the palm of the hand, or it becomes extremely viscous and hard, making it difficult to use as a hair treatment agent.

In addition to the above-mentioned essential components, the hair treatment composition of the present invention contains 9 general ingredients that are optionally incorporated into a hair treatment agent, such as appropriate oils, higher alcohols, humectants, crude drugs, lanolin derivatives, Protein derivatives, water-soluble polymers, preservatives, fungicides, ultraviolet absorbers, antioxidants, two pigments, fragrances, and the like may be added to the extent that they do not impair transparency and gelling properties.
