Description

Liquid cosmetic

The present invention relates to a liquid cosmetic material which is combined with a phospholipid, a bifurcium glutamate lysate, and an electrolyte cosmetic component. More specifically, it relates to a liquid cosmetic which has good storage stability even in the presence of an electrolyte, and has a moisturizing feeling of use, does not cause stickiness, and has a high softening effect.

In the past, electrolytes have been used in liquid cosmetics such as lotions, lotions, and beauty liquids as a cosmetic ingredient for the skin. For example, a moisturizing agent (amino acid, sodium lactate, sodium pyrrolidone carboxylate, etc.), an anti-inflammatory agent (dipotassium glycyrrhizinate, etc.), a whitening agent (L-ascorbic acid-2-phosphate) used as a cosmetic component Etc.), ultraviolet absorber (phenyl benzimidazole sulfonate, etc.) and the like.

However, when the above-mentioned electrolyte cosmetic component is combined with the liquid cosmetic, the electric double layer of the surface of the small vesicle such as the liposome and the emulsified droplet in the liquid cosmetic is compressed due to the influence of the electric charge, because sometimes Small vesicles will produce agglutination. Combination and milk coagulation significantly reduce stability and not easily ensure stability.

At present, the liquid cosmetic with electrolyte is reviewed for a combination of a microemulsion composition containing a specific proportion of apolar oil and a polar oil (refer to Patent Document 1), a polyglycerol fatty acid ester, and a 2-hydroxy fatty acid having a carbon number of 10-22. (Reference Patent Document 2) and a combination of a higher fatty acid and a nonionic surfactant having an HLB of 10 or more (see Patent Document 3).

Patent Document 1: JP-A-2002-138014 (Page 1 to Page 7)

Patent Document 2: JP-A-9-110635 (Page 1 to Page 7)

Patent Document 3: Patent No. 3434115 (Page 1 to Page 8)

However, in the past, in order to ensure the preservation stability of liquid cosmetics, a large amount of surfactants and water-soluble polymers are required, and in this field, when applied to skin, surfactants and water-soluble polymers are produced. Slip adhesion, sticky feeling, etc., not only can not be fully satisfied on the use surface, and can not be fully satisfied with the soft feeling.
