Opacifying Agents are ingredients deliberately added to cosmetic products to reduce their clear or transparent appearance. Some opacifying agents provide the pearly appearance desired in certain products. Other opacifying agents are used in skin (make-up) products for covering purposes and to hide blemishes. Most emulsions and suspensions are opaque as a result of the presence of a liquid or solid disperse phase. Thus, a very large number of substances could be classified as opacifying agents. Instead, the listing below is limited to those substances which are deliberately added to cosmetic preparations for the express purpose of making them more opaque in bulk or after application to the skin. |
