A broad spectrum, emulsion sunscreen composition having an SPF value of at least 30, wherein the composition

• (xx) does not contain an organic sunscreen active that absorbs ultraviolet radiation and
• (yy) contains only a physical sunscreen active ingredient, Zinc Oxide, having
• (i) a porous structure, such that when pores within Zinc Oxide particles are filled with an excipient, the refractive index of the Zinc Oxide particles is reduced,
• (ii) an average particle size of greater than about 100 nanometers, such that the Zinc Oxide is visibly transparent when the sunscreen composition is applied to skin, and
• (iii) is water resistant for 80 minutes as determined in accordance with the test method codified at 21 CFR § 201.327(i)(7),
