JP2549554B2 - Hair treatment agent - Google Patents

Description

TECHNICAL FIELD The present invention relates to a hair treatment agent which is used as a hair rinse, a hair conditioner and the like and has an excellent effect for preventing thermal damage to hair by a dryer or the like. More specifically, the present invention relates to a hair treatment agent that prevents heat damage to hair and damage caused by brushing, and improves the finish after blowing hair with a dryer or the like.

2. Description of the Related Art A wide variety of hair treatment agents are commercially available, and these are applied and sprayed on wet or dry hair after washing the hair, and then the hairstyle is adjusted using a curler or a brush. In addition, hair treatment may be performed by applying a hair treatment agent to dry hair. In recent years, forced drying using a dryer, a hot curler or the like has been increasing as such a drying process. However, during such a drying process, the hair is about 80-95 ° C.
Contact with hot air or heat for a long time. As a result, the hair is damaged, the texture is changed, smoothness,
It is not soft and may cause dryness. Also,
Conventional hair treatment agents also have drawbacks such as stickiness.

Hair is a physiologically dead tissue, chemically damaged hair does not restore, and the tip of the hair becomes flaky. Various studies have hitherto been conducted to prevent such dryness of hair, but a satisfactory hair treatment agent has not been obtained yet. That is, Japanese Patent Application Laid-Open No. 52-47923 discloses that a hair cosmetic composition comprising a diol derivative and methylpolysiloxane exhibits an excellent effect on brushing properties, but it does not show the dryness of the tips on the hair. It has not been improved.

Further, JP-A-52-66638 discloses that a hair conditioning composition comprising polyethylene glycol, polyoxyethylene sorbitan monolaurate and silicone oil gives hair gloss and makes it supple. No mention is made of improvement in the dryness of the tips of the hair. As a result of intensive studies to solve these problems, the present inventors have surprisingly solved the problem by adding (c) to the components (a) and (b) described in the claims. I found that.

That is, an object of the present invention is to provide a hair treatment agent which can prevent damage to hair due to heat or brushing and can obtain an excellent finish of hair after blowing.

Means for Solving the Problems The present invention includes (a) a quaternary ammonium salt represented by the following formula [I], (b) (i) an organopolysiloxaneoxyalkylene represented by the following formula [II] A polymer, and (ii) one or more siloxane derivatives selected from the group consisting of water-insoluble siloxane derivatives represented by the following formula [III], (c) Randium domesticham jack Burduke or Ran Crude extract obtained from pericarp of dium domesticum jack bar lancer, randic acid as its component,
It is intended to provide a hair treatment agent containing one or more selected from the group consisting of landioside and derivatives thereof.

The quaternary ammonium salt contained in the hair treatment agent of the present invention has the following formula: [Wherein one or two of R _{1 to} R ₄ is an alkylamidopropyl group having 10 to 30 carbon atoms, an alkyl group having 10 to 24 carbon atoms, a hydroxyalkyl group having 10 to 24 carbon atoms, or R ₅ (OCH ₂ CH
₂ ) _{1 to 10-} (provided that R ₅ is an alkyl group or a hydroxyalkyl group having 10 to 24 carbon atoms); other R _{1 to} R ₄ are 1 to 10 carbon atoms
An alkyl group of 3, or (Wherein R ₆ is hydrogen or a methyl group); X means a halogen or an alkylsulfuric acid residue having 1 to 2 carbon atoms]. Specific examples of the quaternary ammonium salt include alkyltrimethylammonium chloride, alkyltrimethylammonium bromide, dialkyldimethylammonium chloride, dialkylbis (2-hydroxyethyl) ammonium chloride,
Examples thereof include dialkylmethyl (2-hydroxyethyl) ammonium chloride, alkyldimethyl (2-hydroxyethyl) ammonium chloride, alkylpentaethoxylated ammonium chloride, dialkylpolyethoxylated ammonium chloride, ethylsulfated alkylamidopropylethyldimethylammonium and the like.
These may be used alone or in combination as appropriate. Particularly, it is preferable to use one kind or two or more kinds of alkyltrimethylammonium chloride. Specific examples of the alkyltrimethylammonium chloride include palmityltrimethylammonium chloride, behenyltrimethylammonium chloride, tallow alkyltrimethylammonium chloride, stearyltrimethylammonium chloride and the like, preferably behenyltrimethylammonium chloride and stearyltrimethylammonium chloride. is there.

The blending amount of these quaternary ammonium salts is preferably 0.01 to 5% by weight.

Next, the organopolysiloxane oxyalkylene copolymer has the following formula: [In the formula, R ₇ and R ₈ are hydrogen, an alkyl group having 1 to 3 carbon atoms or a phenyl group; x is an integer of 0 to 3; when y ≠ 0 and z = 0, p
= 1, 5 ≦ m + n ≦ 50; when y = z = 0, p = 0,1, 1 ≦
m + n ≦ 1000].

The water-insoluble siloxane derivative has the following formula: [Wherein R ₉ and R ₁₀ are alkyl groups having 1 to 3 carbon atoms, 3 ≦ q
≦ 6]

These compounds of formula [II] and formula [III] are independently
Alternatively, two or more kinds may be mixed and used.

As a specific organopolysiloxane, for example,
Examples thereof include dimethylpolysiloxane, methylphenylpolysiloxane, polyoxyalkylene-modified polysiloxane, cyclic polysiloxane, and aliphatic alcohol-modified polysiloxane.

The blending amount of these organopolysiloxanes is 0.01 to 20.
% By weight. If the blending amount is less than 0.01% by weight, the effect of preventing the dryness of the hair is not sufficient. On the other hand, if it exceeds 20% by weight, stickiness becomes remarkable, which is not preferable.

Next, a method for extracting, separating and purifying a crude extract, randic acid and landioside, which are obtained from the skin of Duke or lancea to be added to the hair treatment agent of the present invention, and the structure thereof are known (see, for example, Japanese Unexamined Patent Publication 60-243020), commercially available. In addition, as the derivative, a salt of Langic acid (for example, sodium salt, disodium salt, etc.), an ester (for example, having 2 to 12 carbon atoms)
Monoalkyl ester, dialkyl ester having 2 to 12 carbon atoms), randioside salt (for example, sodium salt, potassium salt, etc.), ester (for example, 2 carbon atoms)
~ 12 monoalkyl ester etc.) and the like, and can be produced by a conventional method.

These components are preferably incorporated in the composition in an amount of 0.0001 to 5% by weight in terms of Langicic acid, Landioside and their derivatives. When the content of these components is less than 0.0001% by weight, excellent hair moisturizing feeling, smoothness,
No suppleness and natural luster, and poor conditioning effect. On the other hand, if it exceeds 5% by weight, the smoothness of hair is lowered and stickiness occurs.

Further, other components may be added to the hair treatment agent of the present invention within a range that does not impair the effects of the present invention. Hydrocarbons such as liquid paraffin, petrolatum, solid paraffin, squalane and olefin oligomers; isopropyl myristate, isopropyl palmitate, stearyl stearate, octyldodecyl myristate, octyldodecyl oleate and triglyceride 2-ethylhexanoate. Higher alcohols such as cetanol, stearyl alcohol, behenyl alcohol and hexyldecanol; emulsifiers such as glyceryl monosteanote, sorbitan monopalmitate, polyoxyethylene cetyl ether, polyoxyethylene stearic acid ester and polyoxyethylene sorbitan monolaurate Methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose and mosquitoes Cellulose derivatives such as onionized cellulose; thickeners such as natural polymers; moisturizers such as ethylene glycol, propylene glycol, 1,3-butylene glycol, glycerin and sorbitol; and other solvents, germicides, perfumes, etc. To be

The hair cosmetic composition of the present invention is used for various applications in the form of a hair rinse agent, a spray-type or dispenser-type hair conditioner, a hair lotion, a gel-like hair treatment, etc. based on a known method.
