Description

  The present invention relates to a liquid base for cosmetics. More specifically, the present invention relates to a liquid base containing an organic dispersion medium and a higher fatty acid metal salt.

  Conventionally, bases in the manufacture of cosmetics include bases that are solid or liquid at room temperature, and liquid bases have merits such as handling properties during blending and ease of measurement. Used in cosmetics. As the liquid base, an aqueous base that is easily dissolved in water at room temperature or an oil base that is difficult to dissolve in water is used. Of these, aqueous bases are used in cosmetics such as shampoos, rinses, body soaps, hair styling agents, lotions, cosmetic liquids, moisturizing creams, and cosmetic milks. On the other hand, oily bases are used in cosmetics such as cleansing compositions for make-up removers, hair rinses, hair treatments, hair styling agents, liquid foundations, sunscreen creams, moisturizing creams, and cosmetic emulsions. These liquid aqueous bases or oily bases are composed of various constituents. However, as a component for improving lubricity when applied to the skin or hair as a cosmetic, an aqueous base has been conventionally used. Various surfactants and the like have been used as components for the oil, and silicone oils and the like have been used as the components for the oily base. However, the incorporation of various surfactants alone is not sufficient for lubrication, and silicone oils often cause stickiness to remain on the hair or skin on which cosmetics are applied. As a non-sticky lubricant, a higher fatty acid alkaline earth metal salt is known (Patent Document 1), and the use of this as a component in a solid base is also proposed (Patent Document-). 2). However, when these higher fatty acid alkaline earth metal salts are blended as an aqueous or oily liquid base lubricant, these salts are usually hardly dissolved in the liquid base and do not stably disperse. In many cases, sediment was formed over time.
