摘要： A broad-spectrum UV photoprotective composition is described. The composition is characterized in that the composition comprises mesoporous zinc oxide aggregates having an average aggregate size of at least 0.8 microns dispersed in a carrier and the composition is visibly transparent. Sufficient zinc oxide is included in the composition to achieve an SPF greater than 15, greater than 25, greater than 30, or greater than 50.

摘要： A zinc oxide powder is described, which, when used in a dispersion at a concentration of at least 50 wt % of zinc oxide, produces a transparent composition having a total visible transmittance through a path length of 20 microns at 550 nm of at least one of; at least 70%, at least 75%, at least 80% or at least 85%. The powder has a number average zinc oxide aggregate size of at least 0.8 microns, at least 1 micron, at least 2 microns or at least 3 microns. Use of the zinc oxide powder reduces the risk of transdermal penetration.
