New photoprotectors

Posted by Yissum - Research Development Company of the Hebrew UniversityResponsive · Innovative Products and Technologies · Israel

Summary of the technology

Keywords: cosmetics, sunscreens
Project ID : 6-2006-191

Commercial Advantages:

There is a huge market for photoprotectors. Our invention is a platform for a new group of sun–related products with a versatile range of compounds with high applicability for cosmetic and pharmaceutical formulations. The new class of sunscreens is prepared from natural and synthetic available materials approved for human use. The skin substantivity property of the new compounds is an important advantage over the currently used sunscreens. Another advantage of this ingredient is that it offers for the formulators of emulsions and creams the use of this compound as the oily phase and as a sunscreener in their compositions at the same time.

Their use will generate new improved cosmetic and pharmaceutical products as demanded by the actual market needs.

General Background:

Existing skin photoprotectors being small organic molecules do not remain confined to the surface of the skin being washed up from the skin. Generally, their protective action is only very short. Therefore the development of long-lasting photoprotectors confined to the skin, particularly those based on natural products, remains an actual task.

The present invention relates to the preparation and use of photoprotectors (uva& uvb) with skin substantivity.

Current Status:

New sunscreens have been prepared, identified and tested at laboratory level for their physico-chemical properties and substantivity (residue on skin after bath).

An application for patent has been submitted.

Future Plans:

Licensing and support for testing and development

Applications and Potential Markets:

The new compounds will be used in cosmetic and pharmaceutical products.The Cosmetic, Pharmaceutical and Chemical industries and Raw material manufactures are the potential markets for this new class of products.
