Description

Conditioner composition with excellent hair softness and smoothness {HAIR CONDITIONER COMPOSITION HAVING IMPROVED SM00THNESS AND SLIPPERY FEEL ON DRY HAIR}

The present invention relates to a hair conditioner composition, which is more excellent in emulsifying power for oils and the like that provide a conditioning effect to the hair, and significantly improves the softness and smoothness of hair during wet and dry, as well as improved low temperature stability. It relates to a composition.

Sebum secreted from the scalp contaminates human hair through contact with the environment. Such contamination can cause the appearance of hair to be dirty, oily and cause unpleasant feelings to others. Therefore, regular hair washing is necessary. However, while hair washing removes excessive sebum and dirt from the hair, the trituration process can entangle the hair in wet conditions, making it difficult to trim.

Various methods have been developed to solve the above problems caused by hair washing, and many methods using a hair conditioner of a shampoo or lotion type after shampooing have been widely used. For the convenience of users, the shampoo is added to the conditioning ingredients, but the disadvantage is less effective than the conditioner used after the shampoo.

Generally, conditioners emulsify higher alcohols using nonionic surfactants or quaternary cationic surfactants, and then give hair conditioning effects to hair by containing oils, waxes, and silicones, which are hair conditioning raw materials. However, in this case, there is a disadvantage in that the feeling of massage, softness, such as when rinsing drops.

In order to overcome this disadvantage, Japanese Patent Application No. 昭 44-49524 (Richardson Company, June 24, 1969) has disclosed a hair treatment composition using a reaction of a tertiary amidoamine with an inorganic and organic acid. Application No. 平 5-271036, Japanese Patent Application Laid-Open No. 2000-53537, Japanese Patent Application Laid-Open No. 2003-81783, Japanese Patent Application No. 2003-146846 (Kai Kao) include tertiary amidoamines, organic acids, and higher fatty alcohols as basic prescriptions. N-long-chain acyl basic amino acid lower alkyl ester, polymeric silicone, alkyllowylalkyl taurine surfactant, glycol, cationic surfactant, ester oil, organic acid ester of polyhydric alcohol condensate, etc. A treating agent composition has been disclosed, and similarly, tertiary amidoamines in WO 02/19976 and US Pat. No. 6,365,142 (above PIENGE) are similarly disclosed. The present invention discloses hair conditioning compositions which are based on organic acids, higher fatty alcohols, and which have high molecular weight ester oils, oily compounds, cationic polymers, and the like.

In all the patents disclosed above, the acid for neutralizing the tertiary amido amines is inorganic acid (hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid), organic acid (acetic acid, lactic acid, citric acid, formic acid, propionic acid, tartaric acid, malic acid, male) Acids, fumaric acid, succinic acid, tartronic acid, dimethylol propionic acid, EDTA, aromatic sulfonic acid, aromatic carboxylic acid, glutamic acid, aspartic acid, arginine, trimethylglycine, silk powder, silk extract, pyrrolidone carboxylic acid) Is being presented.

The tertiary amido amine neutralized with the acid has a low irritation and a good massage feeling, but it is known to have a poor conditioning effect such as hair softening effect, smoothness, and softness, compared to quaternary ammonium salts.

In order to solve the above problems, the present inventors use a quaternary ammonium salt, but when using a new cationic compound in which the glyceryl group is added to the present invention, the emulsifying power is excellent due to the addition of an additional hydrophilic component, and the hair adsorption power is used. This increase was found to not only increase the usability and hair conditioning effect when wet, but also to increase the low temperature stability and completed the present invention.

Accordingly, an object of the present invention is to provide a hair conditioner having excellent emulsifying power, a feeling of softness and smoothness when wet, and a hair conditioning effect as well as excellent low temperature stability.

In order to achieve the above technical problem, the present invention comprises a combination of a cationic surfactant having a specific structure represented by the following formula (1) and a conventional quaternary ammonium salt represented by the following formula (2), a higher fatty alcohol and a water-insoluble nonvolatile silicone component It provides a conditioner composition characterized in that.

Test Example  2: hair Smoothness evaluation

In order to evaluate the smoothness of the hair conditioner composition prepared in Examples and Comparative Examples, the coefficient of friction of the hair after wet and dry was measured. The hair used was a European dark brown hair obtained from De Meo Brothers, USA, made of a 18 cm long and 1.5 g tare. The hair tareres were washed with a conventional shampoo, treated with 1 g of the product of Examples and Comparative Examples for 1 minute, rinsed with running water for 30 seconds, squeezed out, and the coefficient of friction at the time of wetness was measured. The friction coefficient of dry hair was measured after drying for 12 hours under constant temperature and humidity conditions of 25 ° C and 50%. The instrument used was a MTT-160 tensile strength tester obtained from Dia-Stron, UK, the friction speed was 300 mm / min, the vertical load was 100 g. The coefficient of friction is obtained by the following equation (1), and the smaller the coefficient of friction, the more smooth. The experimental results are shown in Table 3 below.
