Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a hair cosmetic,
More specifically, the present invention relates to a hair cosmetic such as a hair setting agent, a styling agent, a hair styling agent, and the like, having both excellent set holding power and good feel to hair.

[0002]

2. Description of the Related Art Hair setting agents which have been widely used in the past are obtained by dissolving a film-forming polymer compound in water, a lower alcohol or a mixed solvent thereof. The polymer compound blended here has the effect of fixing the hairs together and holding the set, but the ones that have been used conventionally have stickiness in the process of applying to the hair and drying it. It wasn't smooth. In order to solve such disadvantages, attempts have been made to improve the feel in use by adding oils and fats for cosmetics, surfactants, and the like to the polymer compound. However, a hair setting agent having both sufficiently satisfactory set holding power and use feeling has not yet been obtained.

[0003] In recent years, hair treatment agents containing an amphoteric polymer compound and a cationic polymer (JP-B 2-44446).
And Japanese Patent Publication No. 3-14805, and a hair treatment agent containing an amphoteric polymer compound and an anionic polymer (Japanese Patent Publication No. 3-21524). However, these treatment agents are not satisfactory in terms of non-stickiness and smoothness from application to drying, and also have a feeling of roughened finished hair, which is not satisfactory.

Further, for the purpose of coating the split ends of hair, a hair cosmetic using a combination of a polysiloxane-oxyalkylene copolymer and a silicone derivative has been developed, which has a good feel. And has been reported to be excellent in adhesion of split ends (Japanese Patent Laid-Open No. 6-1).
No. 57247). However, even this method was still incomplete in terms of set holding power and hair smoothness.

[0005] Therefore, the fixing force between the hairs is sufficient,
There was a need for the development of hair cosmetics that had a formed film that was rich in elasticity, did not give a rough feel, had excellent style holding power, and was non-sticky, smooth, and easy to make in the process from application to drying. .

On the other hand, the present inventors have found that a hair cosmetic having a good feeling of use can be obtained by using a specific cationic resin (JP-A-8-11).
3517, JP-A-8-26938 and JP-A-8-208442).

[0007]

Under these circumstances, the present inventors have conducted intensive studies and as a result, have found that by using a specific cationic resin and a plant extract together, an excellent set holding power and a good set retention can be obtained. The present inventors have found that a hair cosmetic having both touch and touch can be obtained, and completed the present invention.

[0008] That is, the present invention is a hair cosmetic comprising the following component (A) and one or more plant extract extracts.

If the amount is too small, the cationic resin finally obtained becomes sparingly soluble in water, and the removability at the time of hair washing becomes poor, and the cationic resin slips on the hair due to a decrease in cationic performance. Properties, combability, and the effect of imparting a conditioning effect are reduced. Conversely, if the amount used is too large, the resulting cationic resin will have a sticky feeling, or will cause problems such as a reduction in the hair styling effect.

The polymerizable unsaturated monomers for copolymerization include:
In addition to the polymerizable unsaturated monomers (1) and (2), other polymerizable unsaturated monomers, which are not essential components, can be used. By appropriately selecting the other polymerizable unsaturated monomer to be used, the feel and the like can be adjusted by imparting appropriate flexibility and hardness to the finally obtained cationic resin.

(2) Smoothness after application After drying, 20 subjects applied 3 g of a sample to a hair strand (4 g), adjusted the shape with a comb, and evaluated the smoothness until drying. The evaluation criteria are the same as in the above (1).

(3) Set Retention Force 0.5 g of a sample was evenly applied to a hair bundle having a length of 15 cm and a weight of 1 g, wound around a rod having a diameter of 2 cm, and allowed to stand in a high-temperature room at 45 ° C. for 6 hours. And dried. After drying, the rod was removed, and the apparent length (L ₁ ) of the hair bundle was measured.
Next, the hair bundle is hung in a thermostatic chamber at a temperature of 25 ° C. and a humidity of 90%, taken out after 30 minutes, and again taken as the apparent length (L) of the hair bundle.
₂ ) was measured, and the set retention effect was determined by the following equation.

[0057]

[Formula 1] Set holding force = ｛(15−L ₂ ) / (15−
L ₁ )｝ × 100 (%)

Therefore, the closer this value is to 100, the higher the set holding effect. ◎: very good (set holding power 80% or more) ○: good (set holding power 50% or more, less than 80%) △: slightly bad (set holding power 30% or more, less than 50%) ×: bad (set holding power) Less than 30% force)

(4) Low Roughness of Finished Hair The dryness of the hair strand dried in (1) was sensory evaluated by 20 test subjects. Evaluation criteria are
Same as (1) above.

As is clear from the results shown in Table 1, the hair cosmetic composition of the present invention was excellent in set holding power, non-sticky, and had a smooth and good feel.

[0062]

As described above, the hair cosmetic composition of the present invention has a good feeling such that the hair is not sticky and easy to give in the process from application to drying finish, and the finished hair is smooth and does not get rough. In addition, the set holding power is excellent.
