Abstract

PURPOSE:A hair cosmetic, obtained by blending a dilong-chain and dishort-chain type quaternary ammonium salt having an iodine value with a specific range, i.e. a specific amount of unsaturated bonds in the molecule with an amphoteric surfactant, capable of giving improved softness and having improved feeling of use at the same time. CONSTITUTION:A hair cosmetic, obtained by blending a quaternary ammonium salt, expressed by the formula (R1 is 14-22C alkenyl; R2 is 14-24C alkyl or alkenyl; R3 and R4 are methyl, ethyl, polyoxyethylene or polyoxypropylene; X<-> is anion) and having 35-100, particularly 40-90 iodine value range, e.g. dioleylmethylammonium chloride, etc., with an amphoteric surfactant, e.g. amidoamine type amphoteric surfactant, etc., at 1:2-2:1 weight ratio together. The total amount of both blended ingredients is 1-5wt%.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hair cosmetic that can impart flexibility not only to normal hair but also to damaged hair, and which also provides a soaked feeling when used. .

Problems to be Solved by the Invention Normally, hair is coated with sebum secreted from the hair itself, but when hair is washed with soap, synthetic detergent, etc., more sebum is removed than necessary. Therefore, wash I)! The remaining hair loses its smoothness and becomes hard to the touch, making it difficult to comb. In order to solve the inconveniences associated with hair removal, various hair styling needles have been used as preparations for hair treatment after hair washing. The products used for these hair cosmetics are dialkyl dimethyl ammonium salts, dimethyldimethylammonium salts, dimethylammonyl salts, alkyltrimethylammonium salts, dimethylammonium salts, dimethylammonium salts, dimethylammonium salts, and alkyltrimethylammonium salts. 7) Quaternary ammonium salts such as long-chain alkyl 1-short chain alto-7nium salts are referred to as active ingredients.
Luzi%? j R1 alkylaminium salts are particularly often used due to their excellent softening ability, but since they are highly lipophilic, they are well absorbed by normal hair, which has a hydrophobic hair surface. However, for damaged hair that has undergone perm bleaching, etc., the hydrophilic nature of the hair surface weakens its adsorption properties, and the softening effect is insufficient. In addition, 7) long-chain alkyl tri-short-chain alkyl ammonium salts have high hydrophilicity, contrary to the above ammonium salts,
It has high adsorption properties on damaged hair and exhibits good flexibility, but it has poor adsorption properties on normal hair and its softening effect is insufficient.

As described above, conventional hair cosmetics have not been able to provide soft application to both normal hair and damaged hair using their main active ingredients alone.

Furthermore, conventional 2G hair cosmetics such as hair rinses are formulated with hydrophilic nonionic surfactants to spread the hair rinse throughout the hair, giving foaming properties and improving the V1 feeling of use. However, when a hydrophilic nonionic activator is blended in this way, the cationic activator mixes with the nonionic activator to form micelles, resulting in poor adsorption of the cationic activator to the hair, and a sufficient softening effect cannot be imparted. A problem will arise.

The present invention was made in consideration of the above-mentioned circumstances, and provides λ1 excellent flexibility for both normal hair and damaged hair, and also provides hair cosmetic benefits with a comfortable feeling of use. The purpose is to

To solve the problems: 1. In order to achieve the above objective, the inventors of wood conducted research on tax considerations, and found that the iodine value within a specific range, or in other words, a specific amount of unsaturated bonds within the molecule, The di-long chain di-short chain type quaternary ammonium salt represented by A, that is, the general formula (T): (wherein, R1 is an alkenyl group having 14 to 24 carbon atoms, R4
is an alkyl group or alkenyl group having 14 to 24 carbon atoms, R3 and R4 are a methyl group, ethyl group, polyoxyethylene group or polyoxypropylene group, and X- represents an anion. ), which is one or a mixture of two or more compounds, and whose iodine value is in the range of 35 to 100. When an amphoteric surfactant is further used in combination with the quaternary ammonium salt, both of them synergistically works, no-
Extremely flexible for both full hair and damaged hair!
The present inventors have discovered that it is desirable to have a hair cosmetic that provides a good amount of moisture and gives an excellent feeling of use, and has thus completed the present invention.

Therefore, the present invention is represented by (Δ) the above general formula 1) and 35 to 100 iodine 11! A quaternary ammonium salt having Ii, (B
) A hair cosmetic containing an amphoteric surfactant is provided.

The present invention will be explained in more detail below.

f of the present invention, quaternary ammonium 4B (A>, which is the first essential component of the hair dye It) has the general formula (D): R1 is alkyl M, R2 is either an alkyl group or an alkenyl group. Yes, 1≧I and 1 (the number of carbon atoms in 2 is 1
4 to 24, preferably 16 to 22, and C having a distribution within this range is fine. Well, Ii, R1 and R2 have the same number of carbon atoms, so b'? However, if the number of carbon atoms in Rl and R is less than 14, the water resistance will increase and the flexibility will be insufficient compared to non-ruling l\)l.
When the number of carbon atoms exceeds 24, hydrophobicity (lipophilicity) increases.
The object of the present invention cannot be achieved because the flexibility against C damage I\no' is insufficient. On the other hand, 1te3 and R4 are methyl j, [, ethyl group, liY consisting of polyoxyethylene 3A and polyoxypropylene M with an average "nA degree of 1 to 5, but it is C is methyl 1.L is I (i9 K').

In addition, 1 and 3 and 1 and 1 and 1 and 1 and 1 and 1 and 2 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 1 and 5 and 1 and 1 and 1 and 5 and

The object of the present invention is achieved because the flexibility is inferior to 1! ? do not have. However, in the present invention, J3
However, it is not necessarily necessary that the quaternary ammonium salt mass represented by the general formula (1) has an iodine number of 35 to 100, and the quaternary ammonium salt mass represented by the general formula (1) The iodine value of the entire quaternary am7nium salt was made to be in the range of 35.-100 by mixing a low one with a high one and one with a high one. Shiyoi.

The quaternary am7nium salts represented by the general formula (D) described above are usually unsaturated higher fatty acids such as oleic acid, linoleic acid, and lylunic acid, < is palm oil fatty acid, and human () oil 11i.

In this case, oleic acid, a mixture of oleic acid and beef tallow fatty acid, and palm oil fatty acid are suitable for 14. When synthesizing the quaternary anthinium salt of the present invention from these Idemitsu raw stones, the known process of, for example, fatty acid → nitrification → secondary aliphatic amination → short chain alkylation → quaternization is performed. However, in this process, the reaction system 1't- is selected so as not to reduce the unsaturated bond ratio of the raw fatty acid and ultimately maintain a high iodine value. It is from et al.

In the hair makeup product 1 of the present invention, the blending point of the quaternary ammonium salt represented by the general formula (C)-C is 0.05 to 10.
It is preferable to set it as % between Φ.

0.05ff! If it is less than at%, the softening effect may not be sufficient, and if it exceeds 10% by weight, it is not only economically disadvantageous, but also may result in a heavy finish.
