Description

Transparent shampoo composition

The present invention relates to a transparent shampoo composition.

In recent years, hair has been damaged by various factors such as wind, heat, sun, pollution, and more specifically, hair may be damaged by physical and chemical deformation due to exposure to the sun, and especially when using a hair dryer. The damage appears to be quite serious. In general, hair dryers start to deform at temperatures between 75 and 100 ° C, and damaged hair at higher temperatures is more severely damaged by subsequent combing. There is a great deal of attention focused on protecting hair from these causes.

In general, shampoo as a hair cleanser has been used to decontaminate the scalp and hair obtained from the source and to keep the hair clean and beautiful. However, in addition to these cleaning purposes for decontamination, it further contains cationic surfactants or cationic polymers for conditioning purposes such as ease of combing, softness, smoothness, shine, reduction of friction on the surface of the hair, antistatic, and hair protection. It was used. However, while it has the advantage of excellent conditioning effect on hair when rinsing and wet and can be used for transparent formulations, the smoothness of the hair is slightly reduced after drying, and the effect of preventing hair damage by heat or combing is not excellent. appear.

Therefore, although silicone is used to give conditioning effects to damaged hair caused by heat or combing, it is difficult to apply to actual products. In other words, the use of a small amount of silicon causes stiffness in the wet hair, and the use of a large amount of opacity decreases product stability and decreases product stability. In particular, the micro-emulsion silicone that can be applied to the transparent shampoo is excellent in the conditioning effect, but poor in stability over time, the polyether siloxane is easily washed and has the disadvantage of poor conditioning effect.

In addition, due to frequent dyeing, there are not only many damages to the hair, but also dyed hair is easily decolored due to the shampoo, and the hair damage is more severe.

There is a need for further studies on transparent shampoo compositions which can prevent hair damage due to heat or combing, and have excellent conditioning effects on hair and color care effects on dyed hair.

Therefore, the technical problem to be achieved by the present invention is to provide a transparent shampoo composition which can prevent hair damage due to heat or combing, and is excellent in color care effect and time stability for dyed hair as well as a conditioning effect on hair.

In order to achieve the above technical problem, the transparent shampoo composition of the present invention contains a polyether aminosiloxane-based silicone.

The frictional force is smaller and the reduction rate is larger than that of the hair using the transparent shampoo composition of Comparative Example 4, which does not use Comparative Examples 2 and 3 and the silicone compound. Therefore, it can be seen that the compositions of Examples 1 and 2 have an excellent effect of softening the surface of the hair.

<Hair damage prevention effect>

After the hair was treated with transparent shampoos prepared in Examples 1 and 2 and Comparative Examples 1 to 4, the combing force was measured to determine the effect of preventing hair damage. Since combing acts to accumulate hair damage, reducing combing force means that hair damage is prevented.

First, six hair tresses are prepared, and the transparent shampoo compositions prepared in Examples 1 and 2 and Comparative Examples 1 to 4 are applied to each of the hair tresses, and then washed and dried with a dryer. , ② loadcell L A & D Max Force 600 gf, ③ Combion Speed: 2,000 mm / min) was used to measure the damage prevention effect to the hair three times.

The combing force is smaller and the reduction rate is larger than that of the hair using the transparent shampoo composition of Comparative Example 4, which does not use Comparative Examples 2 and 3 and the silicone compound. Therefore, it can be seen that the compositions of Examples 1 and 2 impart excellent hair damage prevention effect to the hair.

<Hair Conditioning Effect>

Each of 15 men and women were subjected to the compositions of Examples 1 and 2 and Comparative Examples 1 to 4 in a conventional manner, and then evaluated the conditioning effect (drying and feel) of the hair according to the evaluation criteria of Table 4 below. The results are shown in Table 5 below.
