Abstract
The invention encompasses topical sunblock formulae for shielding skin from ultraviolet radiation, and a composite sunblocking component thereof. The sunblocking component of the formula includes an effective amount of a plurality of particles having diameters in the range of about 0.01-100 microns, each particle including a matrix and a UV-attenuating compound incorporated into the matrix. The composite sunblocking component may include a particle that is colored or transparent, depending upon the matrix, UV-attenuating compound and the particle size. The sunblocking component is dispersible in water and thus in water-based dermatological carriers. The formula includes these particles dispersed within a dermatologically acceptable liquid carrier in at least an amount sufficient to shield substantially all of the skin over which the formula is applied from hazardous effects of ultraviolet radiation.
