Problems solved by technology

[0003] However, if the above-mentioned electrolyte beauty ingredients are mixed in liquid cosmetics, the electric double layer on the surface of liposomes and emulsified droplets in the liquid cosmetics may be damaged due to the influence of charges. Compression causes aggregation and fusion of these vesicles and emulsion stratification, and the stability is significantly reduced, so it is difficult to ensure stability

Abstract

Disclosed is a liquid cosmetic preparation containing an electrolyte cosmetic component and having excellent long-term storage stability. The liquid cosmetic preparation is characterized by containing a phospholipid (A), a dilauroyl glutamic acid lysine salt (B), an electrolyte cosmetic component (C) and water (D), and further containing an oil-based component (E).

Description

technical field [0001] The present invention relates to a liquid cosmetic in which phospholipids, dilauryl glutamic acid lysine (dilauramidoglutamide lysine) and electrolyte cosmetic ingredients are blended. More specifically, the present invention relates to a liquid cosmetic that has excellent storage stability even if it contains an electrolyte, and at the same time has a moist feeling in use, has no sticky feeling, and has a high emollient effect. Background technique [0002] Currently, in liquid cosmetics such as lotion, lotion, and beauty serum, electrolytes are used as cosmetic ingredients for the skin. For example, moisturizers (amino acid or sodium lactate, sodium pyrrolidone carboxylate, etc.), anti-inflammatory agents (dipotassium glycyrrhizinate, etc.), whitening agents (magnesium L-ascorbic acid-2-phosphate, etc.), ultraviolet absorbers (phenylbenzimidazole Sulfonate, etc.) etc. are used as cosmetic ingredients as electrolytes. [0003] However, if the above-...
