Description

Hair kit {Hair kit}

The present invention relates to a hair kit comprising a first agent in a cleaning composition and a second agent in a conditioning composition.

Conventionally, shampoo has been used as a cleaning cosmetic to remove the contamination of the scalp and hair and keep it clean and beautiful, but besides this cleaning purpose, it softens and smooths the hair to facilitate combing, to give the hair shine, and to style the hair. Additional purposes such as providing were required. Accordingly, after using cleaning products such as shampoos, rinse, hair lotion, and creams are additionally applied to the hair to give a conditioning effect, and hair styling products such as mousse and wax are used to transform the hair style into various forms. .

However, these products have a weak degree of adsorption on the hair after use, so its function does not last long, and in particular, when styling products are used, the shape of the hair is not easily modified and the usability is not convenient.

For example, Korean Patent Laid-Open Publication No. 2001-0031479 discloses an aerosol device including a hair cosmetic containing a synthesized polyurethane group, but has a disadvantage in that it can be specifically applied to cosmetics for styling purposes that are not washed out. .

Korean Patent Publication No. 10-0459636 discloses a styling mousse containing polyurethane, but since it is applied to the hair by taking it away from the hand, there is a disadvantage in that it does not provide convenience to consumers.

Accordingly, the technical problem to be achieved by the present invention includes a first agent which is a cleaning composition which makes hair flexible, lasts a long-term conditioning effect, gives elasticity to the hair, and can be easily transformed into a desired hairstyle, and a second agent which is a conditioning composition. It is to provide a hair kit.

In order to achieve the above technical problem, the hair kit of the present invention comprises a first agent made of a cleaning composition and a second agent made of a conditioning composition used to impart a conditioning effect to the hair after applying the first agent to the hair. In the hair kit comprising, the first agent contains a diisocyanate compound and the second agent further contains a compound having a two or more active hydrogen-containing functional groups and a tertiary amine.

Hereinafter, the present invention will be described in detail.

The kit for hair of the present invention comprises a compound having a two or more active hydrogen-containing functional groups and a tertiary amine in order to impart a conditioning effect to the hair after applying and washing the first agent, which is a detergent composition containing a diisocyanate compound, to the hair. A second agent, the containing conditioning composition, is applied to the hair. By applying in this way, the polyurethane formed by the reaction of the diisocyanate compound contained in the first agent and the compound having two or more active hydrogen-containing functional groups contained in the second agent is coated on the hair, thereby making the hair flexible and elastic. Gives a long lasting effect.

Experimental Example 1 Satisfaction Measurement

After recruiting 90 women in their 20s and 30s with high frequency of use of shampoo and rinse, and separating them into 9 groups of 10 people as a group, each group was Examples 1 to 6 and Comparative Examples 1 to 3 A total of nine compositions were used four times or more each week for two weeks, and sensory evaluation was measured. In this case, after using the cleaning composition and the conditioning composition, the hair is heated to the hair using a hot air balloon (hair dryer, hair iron, etc.). Each evaluator evaluated satisfaction in various aspects according to the evaluation criteria described in Table 4 below, the scores recorded by the evaluators were summed, and then divided by the number of evaluators (10) to obtain an average value, which is described in Table 5 below.

Evaluation standard very unsatisfied dissatisfaction usually satisfied very good Score One 2 3 4 5

Softness lubricity Hair elasticity Conditioning Effect Hair shine Overall Satisfaction Example 1 3.3 3.1 3.6 3.4 3.3 3.3 Example 2 3.7 3.4 3.4 3.8 3.4 3.6 Example 3 3.4 3.4 3.5 3.5 3.2 3.4 Example 4 3.6 3.7 4.2 4.4 3.1 4.2 Example 5 3.2 3.5 3.2 3.7 3.1 3.4 Example 6 3.3 3.5 3.3 3.4 3.3 3.4 Comparative Example 1 3.2 3.2 2.4 2.6 2.9 2.8 Comparative Example 2 3.0 2.8 2.9 2.7 3.1 2.9 Comparative Example 3 3.1 3.0 2.7 2.6 3.0 2.8

Referring to the results shown in Table 5 above, when using Examples 1 to 6 in which different kinds of diisocyanate compounds and compounds having two or more active hydrogen-containing functional groups reacted, satisfaction was high in each item. In particular, satisfaction is much higher in terms of hair elasticity and sustainability of conditioning effects.

However, as in Comparative Example 2, even if the cleaning composition contains a diisocyanate compound, it can be seen that the feeling of use is poor if the conditioning composition is free of compounds and catalysts having two or more active hydrogen-containing functional groups. In addition, as in Comparative Example 3, although the compound and the catalyst having a compound having two or more active hydrogen-containing functional groups in the conditioning composition, but does not contain a diisocyanate compound in the cleaning composition, the expected usability is not obtained.

Experimental Example 2 Measurement of Elastic Force

Referring to the results of Table 5, after using the hair kit of the present invention, it can be seen that the hair elasticity increases, but the bending force and hysteresis were measured and compared to more accurately measure the effect on the hair elasticity. .

First, a bundle of 20 g of human hair is prepared to prepare a hair skein, and the hair is treated in the same combination as Comparative Examples 1 to 3 and Examples 1 to 6 and dried for 5 minutes using a hair dryer, thereby bending strength. Bending force and hysteresis were measured using a bending tester, respectively. The smaller the value of the bending force, the weaker the hardness, and the smaller the value of the measured hysteresis means that the hair is more elastic and flexible.

Bending force (gf.cm ² / cm) Hysteresis (gf.cm ² / cm) Comparative Example 1 0.054 0.068 Comparative Example 2 0.067 0.069 Comparative Example 3 0.051 0.055 Example 1 0.035 0.041 Example 2 0.025 0.030 Example 3 0.032 0.034 Example 4 0.014 0.016 Example 5 0.033 0.035 Example 6 0.038 0.039

Referring to Table 6 above, the hairs used in combinations of Examples 1 to 6 generally showed excellent elasticity effects, and in particular, the cleaning composition containing methylene diisocyanate and conditioning containing dipropylene glycol as in Example 4 When the composition is used, the softness of the hair and the elasticity of the hair are shown to be the best, showing a marked difference from the hair used in the combination of Comparative Examples 1 to 3.

As described above, the kit for hair comprising the first agent which is the cleaning composition and the second agent which is the conditioning composition according to the present invention provides not only the conditioning effect to soften and smooth the hair, but also gives the hair excellent elasticity and durability of conditioning.
