UA-Invented Sunscreen Licensed to Leading Aloe Vera Supplier

Professor Douglas Loy and graduate student Stephanie Tolbert develop their research and bring it to the world through commercialization.

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 that it does not seep into the skin. Douglas Loy, a professor who holds appointments in Chemistry and Biochemistry in the Colleges of Science and Medicine – Tucson,  as well as a faculty position in the Department of Materials Science and Engineering in the College of Engineering, 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.
