  • sunscreen cosmetics are widely used to reduce the effect of ultraviolet rays on the skin, but these are mostly those that use ultraviolet scattering powder as an ultraviolet shielding agent and those that use an organic ultraviolet absorber as an ultraviolet shielding agent.

Then, in order to obtain water resistance, the ultraviolet scattering powder is often hydrophobized on the surface of the powder and blended in the oil phase. However, the hydrophobized inorganic powder tends to agglomerate and settle even in the oil phase, which may cause white turbidity / non-uniformity of the composition and whitening when applied to the skin.
