Abstract

PROBLEM TO BE SOLVED: To obtain a hair cosmetic capable of manifesting excellent gloss or coherency of hair and sustaining the effects for a long period by including an oil and a nonionic surfactant having a specific value of hydrophile-lipophile balance (HLB). SOLUTION: This hair cosmetic contains (A) an oil (preferably a glycerol derivative, more preferably a glyceryl mono-fatty acid ester, a glyceryl di-fatty acid ester or a diglyceryl mono-fatty acid ester) and (B) a nonionic surfactant having 10-18 HLB (preferably a polyoxyethylene alkyl ether, a polyoxyethylene castor oil, or the like). Furthermore, (C) a cellulosic derivative is preferably contained. The amount of the ingredient A formulated in the hair cosmetic is preferably 1-30 wt.% and the amount of the ingredient B formulated in the hair cosmetic is preferably 2-25 wt.% For example, a hair foam is cited as the dosage form of the hair cosmetic. Thereby, good gloss and coherency of a hairstyle can be imparted to hair and the persistence thereof for a long period can be expected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic which can impart long-term gloss and cohesiveness to a hair for a long time.

[0002]

BACKGROUND OF THE INVENTION In order to impart desirable gloss and cohesion to hair, a high refractive index oil such as methylphenylpolysiloxane, paraffin, ester oil or the like is used for the purpose of imparting gloss during composition. There is a method in which a set base (mainly a polymer compound having excellent adhesiveness) is blended. However, in this case, the set base is plasticized depending on the amount of the oil agent added, so that the original hair styling property is difficult to function, and a desirable gloss and cohesion can be obtained immediately after use, but the effect decreases over time.

[0003]

SUMMARY OF THE INVENTION The present inventor has surprisingly obtained excellent gloss and cohesion of hair by combining an oil agent with a nonionic surfactant having a specific HLB value. For a long time.

[0004] That is, the present invention relates to an oil agent and HLB10
To 18 hair non-ionic surfactants.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The oil agent used in the present invention is preferably a glycerol derivative, more preferably one or more selected from fatty acid glyceryl, difatty acid glyceryl and fatty acid diglyceryl, from the viewpoint of the effect of imparting gloss and cohesiveness to hair. . The fatty acid in the oil agent has 12 to 24 carbon atoms,
In particular, the fatty acid chain is preferably 16 to 22, and the fatty acid chain may be linear, branched, saturated or unsaturated. The amount of the oil agent added to the hair cosmetic of the present invention is preferably 1 to 30% by weight (hereinafter simply referred to as%), particularly preferably 1 to 15%, from the relationship between the effect of imparting luster and cohesion and the oiliness.

In the present invention, the above-mentioned oil agent and HLB1
By using in combination with a nonionic surfactant of 0 to 18, excellent gloss and cohesiveness and their sustaining effect can be obtained. When a nonionic surfactant having an HLB outside the range of 10 to 18 is used, In particular, cohesiveness and its durability are reduced. Here, the HLB value is obtained by the Griffin method. Such a nonionic surfactant is preferably selected from polyoxyethylene alkyl ether, polyoxyethylene castor oil and polyoxyethylene hydrogenated castor oil, and the hydrocarbon group in the hydrophobic part thereof has 12 to 24 carbon atoms. Is preferred, and may be linear or branched, and may be either saturated or unsaturated. The amount of the nonionic surfactant added to the cosmetic of the present invention is 2 from the viewpoint of the effect of imparting gloss and cohesiveness and the effect of maintaining the same.
~ 25%, particularly preferably 3 ~ 15%.

[0007] The hair cosmetic composition of the present invention further comprises a set polymer for improving the cohesiveness of the hairstyle,
Resin components such as polyethylene glycol and high molecular silicone; oil components such as silicone oil, hydrocarbon oil and ester oil for adjusting the feel of hair can be blended. In addition, anionic, cationic, nonionic, amphoteric surfactants and higher alcohols can be added to the hair cosmetic composition of the present invention for the purpose of solubilizing and emulsifying each component. Viscous agent, chelating agent, pearling agent, fragrance, pigment,
An ultraviolet absorber, a foaming agent, a propellant, and the like can also be appropriately compounded.

[0008] Examples of the dosage form of the hair cosmetic of the present invention include hair foam, hair spray, hair set mist, hair set gel, curler lotion, set lotion, blow lotion and the like.

[0009]

Examples 1 to 3 and Comparative Examples 1 to 2 The components shown in Table 1 were mixed to prepare mist hair styling compositions of Examples 1 to 3 and Comparative Examples 1 and 2. A professional panelist (n = 10) who has prepared a hairstyle in advance uses these pump sprays, and uses the following method to make the hair feel dry immediately after the spraying, the naturalness of the hairstyle finish, and the cohesion of the hairstyle. The persistence of feeling was evaluated.

(1) Evaluation of hair gloss and unity of hairstyle immediately after spraying When specialized panelists themselves prepare a predetermined hairstyle, they spray a pump spray for evaluation and lightly style the hairstyle with a denman brush for styling. Finished. Shortly thereafter,
The evaluation of the gloss and the cohesiveness of the hairstyle was self-evaluated according to the following criteria.

[Evaluation Criteria of Gloss and Hairstyle Cohesion] 5: Gloss or cohesion is extremely excellent. 4: Excellent gloss or cohesiveness. 3: Gloss or cohesiveness is slightly superior. 2: Gloss or cohesiveness is slightly low. 1: Poor gloss or cohesiveness.

(2) Evaluation of the Sustainability of Hair Gloss and Hairstyle Cohesion Following the evaluation of the gloss and hairstyle cohesion immediately after spraying, and after a further half-day normal life, the gloss and hairstyle Self-assessment of cohesiveness was made according to the following criteria.

[Evaluation Criteria of Sustainability of Gloss and Hairstyle Cohesion] 5: Extremely excellent gloss and cohesion persistence. 4: It is excellent in persistence of gloss or cohesion. 3: Sustainability of gloss or cohesion is somewhat superior. 2: Sustainability of gloss or cohesion is not very long. 1: Sustainability of gloss or cohesion is not maintained.

The obtained evaluation points were averaged and classified into the following four grades based on the average values. The results are shown in Table 1.

◎: average value of 5 to 4.1 ：: average value of 4.0 to 3.1 Δ: average value of 3.0 to 2.1 ×: average value of 2.0 to 1
