CarraShield Labs Granted U.S. Patent 10,688,043

Dr. Mario Tremblay, Chief Science Officer has been granted a U.S. Patent for the company's unique application of carrageenan in a personal lubricant


CarraShield Labs, Inc. has been researching gel formulations for topical use for over 20 years.  Our first product on the market was Divine 9®, a water-based personal lubricant.  This lubricant contains CarraShield®, our formulation technology based on the use of sea algae extracts.  The Divine 9 formulation with CarraShield technology is so unique it has been granted U.S. Patent 10,688,043 "Personal lubricants comprising lambda-carrageenan."  The patent coverage also includes all the European Union, South Korea and Japan.


Research on the ability of the CarraShield technology to help block the transmission of the human papillomavirus (HPV) through skin-to-skin contact has been ongoing since 2006 when the National Cancer Institute published the first paper on in vitro studies they conducted using our formulation.   

Most recently the McGill University Medical School human clinical trial on HPV prevention* was published by the McGill research team.

Study participants using Divine 9 personal lubricant had a lower rate of new HPV infections as compared to participants using a placebo.

This is the world's first clinical trial designed to evaluate a topical gel in reducing the risk of genital HPV infections in women.
