Sun protection and waterproofing—organic silicone film former
Use W/O system sunscreen, because most of the sunscreen is in the external oil phase, and the sunscreen ingredients can be spread continuously, while the oil-soluble sunscreen in the O/W system stays in the oil phase, and the sunscreen is easily dispersed and discontinuous after application, creating a “window” effect”, thereby reducing the effectiveness of sun protection. Therefore, it is necessary to use water-soluble sunscreen agents and add film-forming agents to enhance the waterproof and sunscreen effects of the formula.
