The present invention comprises (i) a median volume particle diameter in the range of 70 to 130 nm, (ii) less than 16% by volume particles having a volume diameter less than 35 nm below the median volume particle diameter, and (iii) the median volume particle diameter. A dispersion of zinc oxide particles having a particle size of more than 84% by volume having a larger volume diameter of less than 57 nm. Zinc oxide dispersions can be used in sunscreen products that exhibit both effective UV protection and improved transparency. Zinc oxide is particularly suitable for use in combination with transparent titanium dioxide.n n n Zinc oxide particles, median volume particle diameter, sunscreen products, transparent titanium dioxide |
