Document Type and Number:
WIPO Patent Application WO/2023/128347
Kind Code:
A1
Abstract:
Disclosed are: a method for producing a titanium dioxide composite pigment; and a titanium dioxide composite pigment produced thereby. According to the method for producing a titanium dioxide composite pigment and a titanium dioxide composite pigment produced thereby according to the present invention, it is possible to: improve efficacy by modifying the surface of a high refractive index inorganic composite pigment through a process of coating the pigment with a film forming agent; bring about the effects of improved dispersion, adhesion, and durability of the inorganic composite pigment in an oil-in-water form; and provide a gel-like titanium dioxide composite pigment that satisfies the user's feeling of use and appears to have a highly moist exterior. In addition, the titanium dioxide composite pigment has a smooth appearance, good spreadability, and a light and refreshing feel when applied to the skin, and can achieve effective UV protection by increasing SPF and PA levels due to having high dispersion and stability in a formulation.
