Description

Non-aqueous conditioner composition

The present invention relates to a non-aqueous conditioner composition that gives flexibility and gloss effect to damaged hair.

Hair damaged by frequent dyeing, perming, etc. is not glossy and rough, making hair difficult to prepare. If only shampoo is used for healthy hair, this problem is more serious for damaged hair, because oil is removed from the hair due to excessive washing, so that it is difficult to maintain a calm hair due to lack of shine and static electricity. To overcome this, shampoos are used, followed by conventional aqueous conditioner compositions in the form of emulsions containing higher alcohols, cationic surfactants, water, silicones and the like. However, such conventional water-based conditioner compositions have the disadvantage that their effect is poor on severely damaged hair.

For example, Korean Patent Laid-Open Publication No. 2003-0050371 discloses a conventional water-based conditioner composition containing water, lower alcohols, polyols, higher fatty alcohols and cationic surfactants to solve the above problems. However, in providing softness and shine to the hair, the use of silicones exhibiting excellent effects is extremely limited, and due to low viscosity, when used in severely damaged hair, there is a disadvantage that shine is poor after drying. There is also the inconvenience of using additional conditioner products for severe hair.

This is because silicone becomes unstable by water, and silicone gives gloss and smoothness to hair, but stability is deteriorated by water. In addition, the water lowers the solubility of the higher alcohol, so as the water content increases, the lower alcohol content, such as ethanol, must be increased. Lower alcohols such as ethanol have the disadvantage of removing the lipid component of the hair. Therefore, the conventional composition contains silicon but does not contain water because it does not secure the stability of the silicone, the problem that the gloss after the hair is dry occurs.

Therefore, the technical problem to be achieved by the present invention is to mix the two compositions, the non-aqueous conditioner composition of the present invention and the conventional water-based conditioner composition just before treatment to the hair to simplify the usability, and to use the silicone contained in the composition of the present invention The present invention provides a non-aqueous conditioner composition that protects stability from water to impart a soft texture and excellent gloss to wet hair as well as dry hair.

In order to achieve the above technical problem, the non-aqueous conditioner composition of the present invention comprises 1 to 90% by weight of a polyol having two or more hydroxy groups; 1 to 90% by weight of polyoxyethylene glycol represented by the following Formula 1; 1 to 50% by weight of lower alcohol having 6 or less carbon atoms; 0.01 to 5 wt% thickener; 0.1 to 10 wt% of a higher alcohol having 12 to 22 carbon atoms represented by Formula 2; And 0.01 to 10% by weight of silicone.

Experimental Example 2 Evaluation of Calorific Value

The temperature after mixing the conventional water-based conditioner composition of Example 1 and the non-aqueous conditioner composition of Example 2 at 25 ° C. in the ratios described in Table 6 below was measured and the results are shown in Table 7 below.

D E F Example 1 50 30 70 Example 2 50 70 30

D E F Temperature before mixing 25 25 25 Temperature after mixing 42.5 39 37.5

As shown in Table 7, D showed the largest increase in temperature compared to E and F. Therefore, the aesthetics are more satisfactory when the mixing ratio is 50:50.

Experimental Example 3 Friction Force Measurement

In Table 6, the frictional forces of the mixed hairs of D, E, and F were measured. When the hair is damaged, the surface of the hair becomes rough because the cuticle of the hair is cracked or lifted. Therefore, it is possible to determine the degree of hair damage by measuring the change in the physical state of the hair. Three tresses (Hair Tress) were prepared for each sample, and the shampoo composition was treated for each sample. After drying the treated sample with dry, physical force on the surface of the hair using friction force tester (① Miniature Tensile Tester MTT600: Dia-Stron Ltd. ② RheoWin Software Rev 3.3a: Dia-Stron Ltd. ③ Extension Speed: 100mm / min) State change was measured. Table 8 below shows the values evaluated by the above experiment. At this time, the friction force (Friction force) as the hair is damaged and the surface is rough, the friction force is larger, so the larger the value, the greater the hair damage.

Experiment D E F Friction force (N) (Friction force) 1 time 0.40 0.38 0.52 Episode 2 0.48 0.39 0.55 3rd time 0.39 0.36 0.6 Average 0.42 0.38 0.56

In Table 8, it can be seen that the average of the frictional force of E mixed with Example 1 and Example 2 at 30:70 was measured as the smallest value of 0.38, which is more frictional force content of Example 2 Because it is reduced.

As seen in Experimental Examples 2 and 3, it was found that mixing the ratios of Examples 1 and 2 at 50:50 gave the best aesthetics, and it was more preferable to increase the content of Example 2 as the damaged hair was used. have.

Experimental Example 4 Evaluation of Differentiation and Convenience of Use

Twenty females were randomly selected as test subjects, using Example 1 at the same ratio as A in Table 3, and then using Example 2 twice a week. One week later, twice a week was used as a method of mixing Examples 1 and 2 in the same ratio as Table A. After using the composition of the present invention in two ways for two weeks as described above, the differentiation and convenience of use according to the method of use of the composition was evaluated. Based on the differential evaluation criteria and the convenience evaluation criteria of Table 9 below, subjects scored subjectively, and then averaged the results.

As shown in Table 10, the non-aqueous conditioner composition and the conventional water-based conditioner composition of the present invention are mixed and used immediately before treatment to the hair. Able to know.

As described above, the non-aqueous conditioner composition of the present invention, which is used in admixture with a conventional water-based conditioner composition just before treatment, is convenient to use and protects the stability of silicone from water, giving luster to dry hair and exhibiting an excellent effect of smooth texture. In addition, heat is effectively generated, allowing a satisfactory aesthetic feeling.
