(57) [Summary] [Structure] A liquid agent containing a fat-soluble substance obtained by mixing a nonionic surfactant and lysolecithin, and an emulsification or a liquid-soluble substance characterized by using a nonionic surfactant and lysolecithin in combination. Solubilization method. [Effect] By using a nonionic surfactant and lysolecithin in combination with a fat-soluble substance, a synergistic effect is recognized and the emulsification / solubilization power is significantly improved. With a small amount of surfactant, it has excellent transparency, is stable without turbidity over time, and can be emulsified or solubilized to a smaller particle size. It is highly safe, has a beautiful appearance, and is easy to take, and can be used for liquid formulation of fat-soluble substances such as pharmaceuticals, foods, and cosmetics. |
