Description

  The present invention relates to a hair cosmetic.

In recent years, the number of consumers who carry out chemical treatments such as perms, bleaches, and hair colors has increased, resulting in hair problems such as damaged hair, untidy hair, poor fingering, dryness, and no gloss. The number of people we have is increasing. In addition, hair is damaged by heat by hair styling by a hair iron and a hair dryer, which are daily beauty acts, and further damages the hair. Therefore, damage care is a very important factor.

  Measures against excessively damaged hair include hair rinses, hair treatments, hair packs, hair masks and other hair care, and hair oils, hair creams, foams, mists, and other non-washing treatments. These hair conditioning compositions often contain cationic surfactants and silicone oils as hair flexibility effects as the main components, and higher alcohols, liquid paraffins, ester oils, sterols to further enhance the conditioning effect. , Nonpolar silicone oils such as lipid, dimethicone, dimethiconol and polyether-modified silicone, peptides or proteins derived from shellfish, fish, silk, plants, seaweed, etc., or derivatives thereof.

Traditionally, sterols, especially phytosterols, are effective in maintaining the wetness of skin and hair and improving skin quality and hair quality, and have an excellent feeling of use. Yes. However, since the melting point of sterols is as high as 100 ° C. or higher, the miscibility and solubility with oil components are poor. Therefore, phytosterol derivatives to which alkylene oxides such as ethylene oxide and propylene oxide are added have been developed so that the miscibility and solubility in oily components are increased even at 80 ° C. or lower. And the cosmetics and hair cosmetics which mix | blended this give a favorable touch also to the hair etc. which received damage, and it is known that it is effective also for long-term continuous use (patent documents 1-3, Non-patent document 1).
On the other hand, dicarboxylic acid diesters are generally low in viscosity, and it is known that cosmetics blended with dicarboxylic acid diesters are well stretched and refreshed when used (Patent Document 4).
It is also known that a hair treatment agent containing a combination of a cholesterol derivative and a dicarboxylic acid diester as a lipid component gives an excellent feel such as moist feeling and softness to the hair (Patent Document 5).

  Phytosterols to which alkylene oxide is added have a touch-enhancing effect on damaged hair as described above. However, according to the study of the present inventors, there are various problems, and their effects are fully exhibited. It turns out that you can't. In other words, phytosterol derivatives to which ethylene oxide has been added increase the hydrophilicity and increase the number of moles of ethylene oxide added, making it easy to blend into the formulation. In order to obtain a feeling of feeling, a feeling of unity of the hair ends, and a moist feeling that persisted over a long period of time, it was not satisfactory. In addition, the phytosterol derivative to which propylene oxide is added increases hydrophobicity and increases the persistence to the hair due to the increase in the number of moles of propylene oxide added, but on the other hand, a solvent-like oily feeling may appear strongly. In some cases, the hair was sticky and the fingering was worsened. Furthermore, the increase in molecular weight decreased the effect of penetrating into the hair, and it was still not satisfactory to obtain a moist feeling that persisted over a long period of time.

  Accordingly, the problem of the present invention is that it contains a phytosterol derivative, has excellent permeability, is non-sticky, has good fingering, is supple, has a natural gloss, has a long lasting moist feeling, excellent repair feeling, and An object of the present invention is to provide a hair cosmetic that is excellent in safety.

  Therefore, the present inventors have studied various hair cosmetics containing phytosterol derivatives to which alkylene oxide has been added. As a result, (A) a phytosterol derivative having 1 to 10 added moles of propylene oxide is used as the phytosterol derivative. By combining (B) dicarboxylic acid diester, (C) dimethiconol, and (D) polyether-modified silicone, the above-mentioned problems that cannot be obtained simply by blending a phytosterol derivative with an alkylene oxide added are solved. The present invention has been found and the present invention has been completed.

That is, the present invention includes the following components (A) to (D),
(A) a phytosterol derivative having an added mole number of propylene oxide of 1 to 10,
