Description

Scalp composition, scalp cosmetic and coating method

The present invention relates to a composition for scalp applied to the scalp. The present invention also relates to a scalp cosmetic using the scalp composition, and a coating method of the scalp composition.

Human scalp is exposed to ultraviolet rays, is stimulated by tricycles, or is heated by dryer drying. Above all, in dryer drying, moisture easily evaporates from the scalp. In this way, the human scalp is damaged daily by various external factors in daily life. In addition, the scalp is in a drier state compared to the skin of other parts such as the face. For this reason, the barrier function of the scalp may be greatly reduced.

When the barrier function of the scalp decreases, hardening of the scalp proceeds, and troubles of the scalp such as dandruff, redness, eczema and itching tend to occur. In addition, such a scalp problem may reduce the strength and elasticity of the hair, or may advance the hair.

Thus, moisturizing care for imparting shine to the scalp is desired. However, the scalp is more sebum in comparison with the skin of other areas. For this reason, even if a normal lotion is applied to the scalp, the moisturizing component hardly penetrates sufficiently, and it is difficult to provide sufficient luster to the scalp.

Moreover, since hair exists on the scalp, it is also difficult to apply the lotion (composition for the scalp) efficiently to the scalp.

Thus, there exist some subjects in the lotion (composition for scalp) applied to a scalp, and the examination which solves the subject is performed. The following patent documents 1-5 disclose the composition for scalp.

Patent Literature 1 below discloses a composition containing a moisturizing agent and adenosine.

Patent Literature 2 below discloses a composition containing at least one of a eucalyptus extract, a polyhydric alcohol, a moisturizing agent, and an anti-inflammatory agent.

Patent Literature 3 below discloses a composition containing an anti-inflammatory agent, a bactericide and polyethylene glycol.

The following patent document 4 discloses the composition containing organic carboxylic acid or its salt. PH at 25 degreeC when this composition is diluted 20 times with water is 1-5.

Patent Literature 5 below discloses a composition containing acetylated hyaluronic acid or a salt thereof, hyaluronic acid or a salt thereof, and hydroxyethylurea.

TABLE 1

The sebum model (anatomical film) was applied to a 200mesh nylon mesh (pseudo-skin) to make a pseudo scalp. Subsequently, the composition for a scalp (composition for a scalp hair) was dripped at the said pseudo scalp, the transmittance | permeability of the said composition was measured, and permeability was judged on the following references | standards.

[Judgement criterion]

○ (good): 60% or more transmittance

△ (slightly good): transmittance of 20% or more but less than 60%

× (poor): transmittance of less than 20%

(3) adhesion and anti-flow

Using the said cosmetic composition for scalp, the composition for scalp was discharged once for the scalp. About 2 g of the composition for scalp was discharged in one discharge. After 1 second of discharge, the adhesion and anti-dripping properties of the composition for scalp applied to the scalp were determined based on the following criteria. 20 people evaluated and adopted the most determination result.

[Judgement criteria of adhesion and anti-dripping property]

○ (good): adhesion is very good, do not flow from the scalp

△ (slightly good): adhesion is good, flows only slightly from the scalp

X (poor): Adhesion is bad, and a lot flows down from scalp

(4) moisturizing

Using the cosmetic for scalp, the composition for scalp was discharged once toward the scalp. About 2 g of the composition for scalp was discharged in one discharge. Moisturizing property on scalp was evaluated 15 minutes after discharge. 20 people evaluated and adopted the most determination result.

[Judgement criteria of moisture retention]

○ (good): The scalp is very moist

△ (slightly good): Scalp slightly moist

× (poor): scalp is not moist

(5) anti-sticking

Using the cosmetic for scalp, the composition for scalp was discharged once toward the scalp. About 2 g of the composition for scalp was discharged in one discharge. After 15 minutes of discharging, anti-sticking property on the scalp was evaluated. 20 people evaluated and adopted the most determination result.

[Judgement criteria of anti-stickiness]

○ (good): no stickiness

△ (slightly good): slightly sticky

× (bad): fairly sticky

(6) the strength and elasticity of the hair

Using the cosmetic for scalp, the composition for scalp was discharged once toward the scalp. About 2 g of scalp composition was discharged by one discharge. Moreover, the composition for scalp adhered to the hair. 15 minutes after the discharge, the strength and elasticity of the hair were evaluated. 20 people evaluated and adopted the most judgment result.

[Judgment Criteria for Hair Strength and Elasticity]

○ (good): The hair has a lot of strength and elasticity

△ (slightly good): slight strength and elasticity of the hair

× (poor): no hair strength and elasticity

The compositions and evaluation results are shown in Table 2 below.

TABLE 2

Moreover, although the evaluation result using the jet spray type trigger container was shown concretely, even when a jet spray type pump container was used, the same evaluation result was obtained.

Moreover, each composition for scalp of Examples 1-5 was filled in the trigger container of the mist system, and said evaluation was performed. As a result, in the discharge by the mist system, the amount of adhesion to the scalp of the composition for a scalp was small compared with the discharge by the jet spray system, and moisture retention property fell. Moreover, since the amount of adhesion of the composition for a scalp to a scalp becomes small, the penetration amount in a scalp becomes small.
