Description

technical field

[0001] The present disclosure relates to an emulsion-type cosmetic composition comprising an inorganic UV blocker and a method for preparing the same. Background technique

[0002] UV blocking agents used in UV blocking cosmetics are roughly classified into organic UV blocking agents and inorganic UV blocking agents. Although the organic UV blocking agent has an excellent UV blocking effect, it causes stickiness and problems related to skin safety due to penetration into the skin. Although inorganic UV blockers are mainly used by dispersing inorganic powders into formulations, they do not cause stickiness and exhibit high skin safety, which can cause white turbidity due to agglomeration of inorganic powders and can provide dry usability. In order to prevent such powder agglomeration problems of inorganic UV blockers and to wet out the UV blockers into the formulation, large amounts of thickeners and dispersants can be added. However, this can cause problem...
