CONSTITUTION:A hair rinse composition containing 0.1-10wt% quaternary ammonium salt, preferably a quaternary ammonium salt (e.g., stearyltrimethylammonium chloride, etc.,) shown by the formula I (R1-R4 are alkyl or hydroxyalkyl; X is halogen or alkyl sulfate) and 0.1-10wt% branched fatty acid cholesteryl ester [e.g., 5,7,7-trimethyl-2-(1,3,3-trimethylbutyl)-octanoic acid, etc.,] shown by the formula II (R has 11-23 total carbon atoms and saturated aliphatic hydrocarbon containing alkyl group between a carboxyl bond position and the center of main chain).

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a novel hair rinse composition, and more particularly to a hair rinse composition containing a specific branched fatty acid cholesteryl ester.

[Conventional technology and its problems]

Conventionally, hair rinses have been used to impart flexibility, smoothness, and antistatic properties to hair, as well as to improve hair combability and make hair easier to handle. Contains it as the main ingredient. However, this alone is insufficient in many respects to achieve the above-mentioned effects, so it is common to add oils and fats such as higher alcohols, glycerides, liquid paraffin, and silicones to hair rinses to supplement their performance.

However, with the combination of these known ingredients, the rinsing effect, that is, the effect of imparting flexibility, smoothness, and antistatic properties to hair, is still not perfect, and there is a major problem in that the rinsing effect is reduced, especially in dry conditions.

[Means for solving problems]

Under such circumstances, the present inventor has made extensive studies to solve the above problems, and has found that if a specific branched fatty acid cholesteryl ester is used as a rinse base, an excellent rinse effect can be exerted even in a dry state, and that it should be even stronger. In particular, they discovered that it is possible to impart beautiful luster to hair, and completed the present invention.

That is, the present invention provides the following two components (A) and (B), (A
) quaternary ammonium salt 0.1 to 10% by weight) of the following formula (I) c, in which R has a total of 11 to 23 carbon atoms, and from the carboxyl bond position to the center of the main chain, there are a few Both are saturated aliphatic hydrocarbon groups having one alkyl substituent) Branched fatty acid cholesteryl ester represented by 0.1 to
A hair rinse composition containing a 10M amount of ti is provided.

The quaternary ammonium salt which is the component (A) of the present invention has the following general formula (If) (wherein 1 or 2 of at -R4 is the length of a straight chain or branched chain having 8 to 22 carbon atoms). chain alkyl or long-chain hydroxyalkyl group, the remainder is an alkyl group having 1 to 3 carbon atoms, a hydroxyalkyl group, or a benzyl group, and X is a halogen atom or an alkyl sulfate group having 1 or 2 carbon atoms) One type or a mixture of two or more quaternary ammonium salts is preferred, and typical examples of these component (A) include stearyltrimethylammonium chloride, distearyldimethylammonium chloride,
stearyltrimethylammonium methosulfate,
N-stearyl-N.

Examples include N,N-tri(polyoxyethylene)ammonium chloride (addition of 3 moles in total), cetertrietherammonium chloride, stearylbenzyldimethylammonium chloride, and the like.

As mentioned above, the amount of the active ingredient added to the hair rinse composition is 0.1 to 10% by weight (hereinafter simply abbreviated as 迤), preferably 0.5 to 3%.

In addition, the branched fatty acid cholesteryl ester represented by formula (I), which is the component (B) of the present invention, is produced by the C% Kosho 59- 23320
Publication No.). Branched fatty acids and cholesterol can be directly reacted to form an ester, or either
It is also possible to direct the force to more reactive derivatives and then esterify them.

Branched fatty acids (RCOOI()), which is a raw material for producing branched fatty acid cholesteryl ester, can have 12 to 24 carbon atoms (R has 11 to 23 carbon atoms);
Those having 4 to 20 carbon atoms (R having 13 to 19 carbon atoms) are preferred, and those having 18 carbon atoms are most preferred. The branched fatty acid must be a saturated branched fatty acid having at least one alkyl substituent from the carboxyl group bonding position to the center of the main chain. Such saturated branched fatty acids can be easily obtained from petrochemical raw materials or oleochemical raw materials.

An example of such a branched fatty acid obtained from petrochemical raw materials is a branched fatty acid having a side chain at the α position, and is represented by the following formula (III).

(In the formula, RS and R6 are each a linear or branched saturated aliphatic hydrocarbon group, and the sum of the number of carbon atoms of R8 and R6 is 12 to 18.) Represented by the above formula (1) A branched fatty acid having a side chain at the 0-position is, for example, converted into an α-branched unsaturated aldehyde by aldol condensation of a linear or branched aldehyde having 7 to 10 carbon atoms, and then hydrogenated and oxidized to form a branched saturated fatty acid. It can be manufactured by a method.

A preferred specific example of the saturated branched fatty acid having a side chain at position 0 is 5,7.7-trimethyl-2-(1,3,3-
Examples include trimethylbutyl)-octanoic acid, 2-hebutylundecanoic acid, and 2-hexyldecanoic acid.

An example of a saturated branched fatty acid obtained from oleochemical raw materials is a fatty acid having a methyl branched chain represented by the following formula (IV).

CHs (CHz)m-CH-(CHz)n-CO
OH(IV)CH3 In formula 1, the sum of m and n is 14, and the distribution is centered around m = n = 7) Such methyl branched chain fatty acids are produced, for example, as a by-product during the production of luic acid dimers. [For example, Journal of American Oil Chemistry (J, Amer, Off Chem.

SOC, ) 51, 522 (1974)), herein referred to as methyl-branched instearic acid. Methyl-branched instearic acid is commercially available, for example as its inpropyl ester (eg Emery, USA).

In addition to cholesterol produced by various methods, it is also possible to use cholesterol extracted from natural substances or obtained by extraction and purification, such as the pulp of dried cow brain.

Among these branched fatty acid cholesteryl esters, methyl branched instearic acid cholesteryl ester is most preferred.

The branched fatty acid cholesteryl ester (1) is contained in the hair rinse composition of the present invention in an amount of 0.1 to 10. 0%, particularly preferably 0.2 to 2%.

If it is less than 0.1%, the effects of the present invention will not be sufficiently exhibited;
．． If it exceeds 0%, the system will gel, which is not preferable.

In the composition of the present invention, the above-mentioned components and ω) are dissolved or dispersed in a suitable solvent such as water, ethanol, chrycerin, ethylene glycol, propylene gellicol, 1,3-propanediol, inpropatol, polyethylene glycol, etc. It is prepared by

The composition of the present invention may further contain known ingredients commonly used in hair rinse compositions, depending on the purpose and necessity, including cationic surfactants other than component (A) and emulsification aids. It is preferable to blend a surfactant selected from anionic surfactants, nonionic surfactants, and amphoteric surfactants. Good results can be obtained by blending these surfactants in the composition of Hebo Rinse etc. in an amount of O, Oi to 10%, preferably 0.5 to 5%.

Furthermore, the composition of the present invention may optionally contain hydrocarbons such as liquid paraffin, vaseline, and solid paraffin; lanolin derivatives such as liquid lanolin and lanolin fatty acids; dimethylpolysiloxane, methylphenylpolysiloxane, and glycol-modified polysiloxane. Silicon derivatives; examples include polyoxypropylene-polyoxyethylene copolymers and their ethers, esters, oils such as higher alcohols, disinfectants, ultraviolet absorbers, fragrances, pigments, etc. 1.
Effects of the Invention The hair rinse agent composition of the present invention, unlike conventional products, can exhibit a good rinsing effect even when the wheat is in a dry state.
