Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hair rinse agent, and more particularly to a hair rinse agent composition having excellent hair conditioning effects.

[Prior art and problems to be solved by the invention] When hair is washed with a shampoo containing an anionic surfactant as a main ingredient to remove dirt from the hair, the dirt and oil that protects the hair surface are removed at the same time. This causes the hair to lose its flexibility, resulting in hair that has no strands and is difficult to comb, making hair more likely to be damaged, split ends, and hair cut.

In order to prevent these harmful effects, hair rinses containing quaternary ammonium salts, which are cationic surfactants, as an active ingredient are used.

Hair rinse agents are intended to impart conditioning effects (softness, moisturizing, smoothness, and combability) to hair.

However, quaternary ammonium salt alone is not flexible.

A sufficient effect cannot be obtained regarding smoothness. Therefore, in order to improve these drawbacks, it has been proposed to incorporate oils and fats such as higher alcohols, glyceride, and liquid paraffin into conventional hair rinses. However, these methods have not yet yielded satisfactory results, particularly in terms of smoothness and flexibility of the hair.

An object of the present invention is to provide a hair rinse agent that has excellent hair conditioning effects (softness, moist feeling, smoothness, and shearability) and a moist finish that does not make the hair heavy after drying.

[Means to solve the problem]

The present invention provides the following: (A)-form [wherein R1 is a lanolin fatty acid residue, R2, R3, R4
R2 is an alkyl group having 1 to 4 carbon atoms, and β is an integer of 2 to 5. ] One or more kinds of lanolin quaternary ammonium salts represented by (B)-formula % formula % (3) [wherein R8 represents a straight chain or branched alkyl group having 11 to 17 carbon atoms, Rz and Rz represent an alkyl group having 1 to 3 carbon atoms. ] A hair rinse composition containing a tertiary amidoamine represented by 2.

The lanolin quaternary ammonium salt which is the component (A) of the present invention is a well-known! I! 71 substances, such as ethyl sulfate lanolin fatty acid aminopropylethyl dimethyl ammonium, ethyl sulfate lanolin fatty acid aminoethyl triethylammonium, ethyl sulfate lanolin fatty acid aminoethyl diethyl methyl ammonium, ethyl sulfate lanolin fatty acid aminoethyl trimethyl ammonium 2 ethyl sulfate lanolin fatty acid Examples include aminopropyl triethylammonium methyl sulfate lanolin fatty acid aminoethyl trimethyl ammonium, methyl sulfate lanolin fatty acid aminopropylethyl dimethyl ammonium, and particularly preferred is ethyl sulfate lanolin fatty acid aminopropylethyl dimethyl ammonium.

The hair rinse composition of the present invention contains 0.1 to 4.0% by weight (hereinafter abbreviated as W%) of one or a mixture of two or more of these lanolin-based quaternary ammonium salts based on the total amount. , preferably 0.3 to 3, Q wt%. Moreover, if the blending amount is less than Q, l w t%,
No good results were obtained for hair conditioning effects,
4. If the OW exceeds t%, the hair becomes sticky and has a heavy finish, which is not preferable.

The tertiary amidoamine which is component (B) of the present invention is a known substance, such as dodecylic acid dimethylaminoethylamide, tetradecylic acid dimethylamizenalamide,
Examples include hexadecyl acid diethylaminoprobylamide, octadecyl acid diethylaminoprobylamide, etc.
Particularly preferred is octadecylic acid diethylamitsuyutylamide.

The hair rinse agent of the present invention contains, based on the total amount, one or a mixture of two or more of these tertiary amidoamines.
-0.1 to 5 for boat fishing. OW t%, preferably 0.
3-3. Q w t% is blended. The blending amount is Q, l
If it is less than wt%, the hair conditioning effect tends to be insufficient.5. If the OW exceeds t%, the finish of the hair after drying becomes heavy, which is not preferable.

The hair rinse agent composition of the present invention has the above-mentioned two components as essential components, and these (A) and (B) 2
The weight ratio of the components is (A):(B) =2:
The ratio is preferably 1 to 6:1, and other components may be appropriately blended into the composition as long as the object of the present invention is achieved.

Namely, hydrocarbons such as liquid paraffin, petrolatum, and squalane, ester oils such as isopropyl myristate and isopropyl palmitate, vegetable oils such as camellia oil, olive oil, and avocado oil, polyglycerin fatty acid esters, polyquine ethylene fatty acid esters, and polyoxyethylene sorbitan. Nonionic surfactants such as monolaurate, cellulose derivatives such as methylcellulose, hydroxyethylcellulose, and cationized cellulose, humectants such as ethylene glycol, propylene glycol, and glycerin, polypeptides, other fungicides, dandruff removers, and chelates. UV absorbers, colorants, fragrances, etc., and one or more of these can be blended.

〔Example〕

Next, the present invention will be explained with reference to Examples, but the present invention is not limited to these Examples.

The test method used in this example is as follows.

``Hair flexibility'', ``Hair moistness'', and ``Hair smoothness J, r<L traversability'' were sensually compared by a panel of 20 female experts, and evaluated using the following criteria.

◎;If the person who answered “good” has a thickness of 18Å or moreQ;
If there are 14 to 17 people, △; is 8 to 1

Both showed inferior performance and could not achieve the purpose of the present invention.

〔Effect of the invention〕

As described above, the present invention has hair conditioning effects (softness, moist feeling, smoothness).

It is clear that the present invention provides a useful hair rinse composition with excellent combability.
