Abstract: A sunscreen cosmetic having an excellent storage stability, while having a high UV protection effect without stickiness, using a liquid UV absorbent with not-so-high UV absorbance per weight concentration as a main UV absorbent will be provided.
A sunscreen cosmetic comprising: (a) 5 to 15% by mass of a salicylic acid-based liquid UV absorbent; (b) 0.5 to 3% by mass of an alkyl silicone wax having a melting point of 60° C. or higher; and (c) a low-viscosity silicone oil, wherein a value obtained by dividing the total of contents of ingredients (b) and (c) by the content of liquid oils ({(b)+(c)}/content of liquid oils) is 0.2 to 0.6.

Abstract: [Problem] An objective of the present invention is to provide an emulsion cosmetic for self-tanning, which has an excellent texture to the touch, which exhibits strong resistance to contact (rubbing) with water, clothes, fingers and the like, and which does not tend to result in uneven coloring. [Solution] The self-tanning emulsion cosmetic according to the present invention comprises (A) core-corona microparticles in which hydrophilic groups are partially provided on surfaces of hydrophobic fine particles; and (B) a self-tanning agent.
