Description

Conditioner composition for hair

The present invention relates to a hair conditioner composition which is excellent in hair conditioning effect and can reduce hair entanglement in wet hair, and more specifically, contains a tertiary amidoamine, a neutralizing agent EDTA, a higher fatty alcohol, and the like. A conditioner composition for hair having excellent conditioning effects such as moisturizing and gloss and preventing tangling in wet hair.

In general, shampoos clean hair by removing excess sebum and dirt. However, in general, after the use of the shampoo in the wet state of the hair is severely entangled in a state that can not be cleaned. In addition, due to excessive degreasing after shampooing, the lack of moisturizing ingredients and natural oils of the hair causes swelling and hair blowing during drying. Therefore, in order to solve the above problem, many consumers use conditioners for hair separately from shampoos.

Generally used hair conditioner is based on cationic surfactant and oil to replenish the oil of hair removed after shampooing, and cationic surfactant is adsorbed on the anionic hair surface to prevent hair damage and static electricity generation. Makes both wet and dry hair easier to care for. In order to provide the above functions, the hair conditioner mainly uses long-chain quaternary ammonium compounds, fatty alcohols, hydrocarbon oils, and silicone conditioning agents. The long chain quaternary ammonium cationic surfactants, higher fatty alcohols and hydrocarbon oils provide hair gloss, moistness and softness. However, these compounds give the hair a dull, sticky or waxy feel when dried. Silicone conditioning agents are also known to provide conditioning effects such as hair softness and ease of combing, but give the hair a dry feeling after drying.

On the other hand, when the quaternary ammonium salt and the tertiary amido amine are used in combination, they reduce hair stickiness and provide softness after drying, but the conditioning effect of wet hair is not satisfactory.

Therefore, there is an urgent need for hair conditioner compositions that provide improved conditioning effects in both wet and dry conditions of hair. Specifically, it is necessary to provide hair with softness without stickiness when the hair is dried and without tangling even when wet.

Accordingly, the present inventors have studied the conditioner composition for hair excellent in hair conditioning effect to solve the above problems, the hair conditioner composition containing tertiary amidoamine, EDTA, higher fatty alcohol, moisturizing, gloss, etc. While excellent in the conditioning effect of the hair, it was confirmed that especially the tangling phenomenon of wet hair, and completed the present invention.

It is therefore an object of the present invention to provide a conditioner composition for hair containing tertiary amidoamine, EDTA, higher fatty alcohols.

In order to achieve the above object, the hair conditioner composition of the present invention is characterized by containing tertiary amidoamine, EDTA, higher fatty alcohols.

Hereinafter, the present invention will be described in detail.

The conditioner composition for hair according to the present invention contains tertiary amidoamine, EDTA, higher fatty alcohols, and has excellent hair conditioning effect. In addition, the conditioner composition may further contain cyclopolysiloxane.

The tertiary amidoamine is also contained in the composition in an amount of 0.1 to 5% by weight, preferably 1 to 3% by weight relative to the total weight of the conditioner composition.

In addition, EDTA (Ethylenediaminetetraacetic acid) contained in the present invention is represented by the following formula (2).

The EDTA is contained in the composition in an amount of 0.1 to 2.0% by weight, preferably 0.4 to 1.2% by weight relative to the total weight of the conditioner composition. On the other hand, it may further contain an acid selected from the group consisting of EDTA, EDTA ₂ Na, EDTA ₃ Na, EDTA ₄ Na or mixtures thereof, the molar ratio of tertiary amidoamine and acid is 1: 0.3 ~ 1: 2 ratio. It contains.

In addition, the higher fatty alcohols used in the present invention are C _16-18 fatty alcohols, for example, cetyl alcohol, stearyl alcohol, cetostearyl alcohol and the like. The content of the higher fatty alcohol is 1 to 10% by weight based on the total weight of the conditioner composition.

In addition, the cyclopolysiloxane used for this invention is D4 or D5, for example, cyclotetrapolysiloxane, cyclopentapolysiloxane, etc. are mentioned. Cyclopolysiloxane is 1-10% by weight relative to the total weight of the conditioner composition.

Meanwhile, the optional ingredients used in the present invention are well known to those skilled in the art as conventional optional ingredients for maintaining basic physical properties and quality, and specific examples thereof include preservatives, thickeners, viscosity adjusting agents, pH adjusting agents, fragrances, and the like. Used.
