UA-Invented Sunscreen Licensed to Leading World Aloe Vera Supplier

Tucson, Ariz. – The University of Arizona has licensed a new non-penetrating sunscreen to MexiAloe Laboratorios, S.A. de C.V., a subsidiary of Novamex.

The novel formulation binds oxybenzone – the active ingredient in most over-the-counter sunscreens – in such a way so that it does not seep into the skin. Douglas Loy,  a professor of Chemistry and Biochemistry in the colleges of Science and Medicine-Tucson, worked with graduate student Stephanie Tolbert to develop the formulation.

Blocking the absorption of oxybenzone into skin would help resolve public concern over the use of the compound which filters out ultraviolet light and is used in many commercial topical sunscreens. The American Association of Dermatology says oxybenzone is safe, but public concerns have been raised about its effects when absorbed by users.

Uncertainty over Trump's Mexico policy 'troubling for world food and agricultural markets'

Bloomberg News: No Evidence of Aloe vera Found in the Aloe vera at Wal-Mart, CVS

Wal-Mart, Target, CVS sell aloe without appearance of plant

The aloe vera gel many Americans buy to soothe damaged skin contains no evidence of aloe vera at all.

Samples of store-brand aloe gel purchased at national retailers Wal-Mart, Target and CVS showed no indication of the plant in various lab tests. The products all listed aloe barbadensis leaf juice — another name for aloe vera — as either the No. 1 ingredient or No. 2 after water. 

There’s no watchdog assuring that aloe products are what they say they are. The U.S. Food and Drug Administration doesn’t approve cosmetics before they’re sold and has never levied a fine for selling fake aloe. That means suppliers are on an honor system, even as the total U.S. market for aloe products, including drinks and vitamins, has grown 11 percent in the past year to $146 million, according to Chicago-based market researcher SPINS LLC.
