<p>Micronized zinc oxide skin protector formulations comprising between about 8 % and 40 % zinc oxide. These compositions preferably comprise micronized zinc oxide, preferably obtained via a 'wet' micronization process in oil, and also preferably include agents that block or screen light in the visible and/or infrared ranges, and also preferably include hydrotropes and humectants to aid in the dissipation of heat caused by the irradiation of light in the visible and/or infrared ranges, and alleviate the photo-damage and/or heat damage associated with such irradiation. These compositions are preferably readily absorbable, transparent, non-irritating, non-comedogenic and are hypo-allergenic. The compositions may comprise additional ingredients such as biological additives (e.g., botanicals and herbals).</p> |
