摘要

"Partu00ecculas dispersion composed of zinc oxide in a dispersion medium, zinc oxide particles, the product of sunscreen, and use of a zinc oxide or dispersion.A dispersion containing particles of zinc oxide having a particle size of dispersion of (I) the diameter of particle of average volume in the range from 70 to 130 nm.(II) less than 16% by volume of particles having a diameter of volume less than 35 nm below the diameter of particle of average volume.And (III) more than 84% in the volume of particles having a diameter of volume smaller than 57 nm above the diameter of particle of average volume.The dispersion of zinc oxide can be used in a product of sunscreen to provide both an effective protection against UV, as transparency is improved.The zinc oxide is especially suited for use in combination with the titanium dioxide transparent.
