  • Nano vs Non-Nano Sunscreen

    The EU has vaguely defined non-nano as “the primary particle size is greater than 100nm,” and Australia defines non-nano as “more than 90% of particles are above 100nm” At the nano level, it is virtually impossible to ensure that a product is nanoparticle free because the shapes of the particles make them hard to measure.
