Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hair treatment agent that is used as a hair rinse, hair conditioner, etc. and has an excellent effect on preventing heat damage to hair caused by hair dryers. More specifically, the present invention relates to a hair treatment agent that prevents heat damage to hair and improves the finish of hair after blowing with a hair dryer or the like.

PRIOR ART AND PROBLEMS A wide variety of hair treatment agents are commercially available, and after applying or scattering these on damp or dry hair after washing, the hair is styled using curlers or brushes. In some cases, a hair treatment agent is applied to dry hair to style the hair. In recent years, forced drying using a dryer, hot curler, etc. has become more common in such drying treatments. However, during such drying treatment, the hair is about 80-95
Prolonged contact with hot air at ℃ or heat.

As a result, the hair may be damaged and its texture may change, causing it to lack smoothness and softness and become frizzy.

Furthermore, conventional hair treatment agents also have drawbacks such as being sticky.

An object of the present invention is to provide a hair treatment agent that prevents hair damage due to heat and provides an excellent finish to hair after blow-drying.

Means for Solving the Problems The present invention provides (a) a quaternary ammonium salt represented by the formula [1] below; (b) the pericarp of R. domesticum jack barduke or R. domesticum jack barlansa. The crude extract obtained, its component ransic acid,
Provided is a hair treatment agent, characterized in that it contains one or more components selected from the group consisting of landioside and derivatives thereof, and (C) a quaternary nitrogen-containing water-soluble polymer. It is.

The Moeki quaternary ammonium salt blended into the hair treatment agent of the present invention has the following formula: [wherein one or two of R1 to R4 has 10 to 3 carbon atoms]
0 alkylamidopropyl group, an alkyl group having 10 to 24 carbon atoms, a hydroxyalkyl group having 10 to 24 carbon atoms,
or Rs(OCH,CHt)+-+.

(However, R5 is an alkyl group or a hydroxyalkyl group having 10 to 24 carbon atoms); the other R1 to R4 are an alkyl group having 1 to 3 carbon atoms, or +c HCHt O) n
H-e (wherein R8 is hydrogen or a methyl group, n is an integer of 1 to 5); X means a halogen or an alkyl sulfate residue having 1 to 2 carbon atoms]. Specifically, such quaternary ammonium salts include alkyltrimethylammonium chloride, dialkyldimethylammonium chloride, dialkylbis(2-hydroxyethyl)ammonium chloride, dialkylmethyl(2-hydroxyethyl)
Examples include ammonium chloride, alkyldimethyl(2-hydroxyethyl)ammonium chloride, alkylpentaethoxylated ammonium chloride, dialkylpolyethoxylated ammonium chloride, and ethylsulfate alkylamidopropylethyldimethylammonium. These may be used alone or in appropriate combination.

In particular, it is preferable to use one or more alkyltrimethylammonium chlorides. Specific examples of the alkyltrimethylammonium chloride include:
Examples include cetyltrimethylammonium chloride, behenyltrimethylammonium chloride, tallow alkyltrimethylammonium chloride, and stearyltrimethylammonium chloride.

The blending amount of these quaternary ammonium salts is 0°01 to 5
Preferably, it is % by weight.

Next, the crude extract obtained from the pericarp of Duke or Langsa, which is another ingredient blended into the hair treatment agent of the present invention,
Methods for extracting, separating and purifying ransic acid and randioside, as well as their structures, are known (see, for example, Japanese Patent Application Laid-Open No. 60-243020) and are commercially available. In addition, derivatives include salts of ransic acid (e.g., sodium salt, disodium salt, etc.), esters (e.g., monoalkyl esters having 2 to 12 carbon atoms, dialkyl esters having 2 to 12 carbon atoms, etc.), randioside. salts (e.g., sodium salts, potassium salts, etc.),
Examples include esters (for example, monoalkyl esters having 2 to 12 carbon atoms), and any of them can be produced by a conventional method.

These components should be present in the composition in an amount of 0.0001 to 8 in terms of ransic acid, randioside, and their derivatives.
It is preferable to mix it by weight%.

If the blending amount is less than 0.0001% by weight, excellent moisturizing, smoothness, suppleness, and natural luster of the hair cannot be obtained, and the conditioning effect is poor. on the other hand,
If it exceeds 8% by weight, the smoothness of the hair will decrease and the hair will become sticky.

Next, quaternary nitrogen-containing water-soluble polymers include quaternary nitrogen-containing cellulose ether, quaternary nitrogen-containing starch, quaternary nitrogen-containing poly(trialkylaminoethyl methacrylate), quaternary nitrogen-containing polyvinylpyrrolidone,
Examples include polymers of diallyl quaternary ammonium salts, quaternary nitrogen-containing guar gum, quaternary nitrogen-containing polypeptides, quaternary nitrogen-containing chitin, quaternary nitrogen-containing silicon, etc. One or two of these A mixture of two or more species can be used. The molecular weight of these quaternary nitrogen-containing water-soluble polymers is preferably 2.000 to 3,000°000, and the nitrogen content is preferably 0.2 to 5% to avoid deterioration in feel due to build-up.

Such a quaternary nitrogen-containing water-soluble polymer can be produced by a method of reacting a water-soluble polymer with a quaternary nitrogen-introducing agent, or by polymerizing a quaternized product, or by a method of quaternizing it during polymerization (JP-A No. 57-116006). , JP-A-58-158799). In this case, water-soluble polymers include cellulose ester, starch, polyvinylpyrrolidone, and the like. Examples of the quaternary nitrogen introducing agent include glycidyltrimethylammonium halide and 3-halogen-2-hydroxypropyltrialkylammonium halide.
