New Study Confirms Skinvisible, Inc.'s Patent-Pending Chlorhexidine Hand Sanitizer Kills The Avian 'Bird Flu' Virus H5N1 On Contact For Up To Four Hours

6/5/2006 12:26:28 PM

LAS VEGAS, June 5 /PRNewswire-FirstCall/ -- A new hand sanitizer could offer greater protection against the spread of the 'bird flu' virus H5N1 through personal contact with carriers of the virus, according to study results released today by Skinvisible Pharmaceuticals, Inc. . The Las Vegas-based research and development company for topical skin applications announced that its patent-pending Chlorhexidine Antimicrobial Hand Sanitizer had a greater than 98 percent inactivation/kill on the "bird flu" virus H5N1 for up to four hours on skin.

The new study, conducted by Retroscreen Virology, a subsidiary of University of London's Queen Mary School of Medicine, differentiates the Chlorhexidine Antimicrobial Hand Sanitizer from other medicinal scrubs or alcohol-based sanitizers and treatments on the market, which only offer protection upon immediate application to the skin. According to Retroscreen, "antiviral hand care products that are shown to inactivate H5N1 will be an important weapon in stopping the spread of this virus. The longer the duration the active stays on the skin to kill the virus the better."

As major international organizations such as the World Health Organization and the Center for Disease Control warn that the H5N1 virus may prove to be the source of the next human catastrophe, Skinvisible is looking to establish its Chlorhexidine Antimicrobial Hand Sanitizer as an essential product for the healthcare industry to inactivate/kill this virus if it should become resident on the hands. This could stop person to person cross contamination.

"We are pleased with these latest studies and are hopeful that by June 30 we will have completed all studies currently underway with success so we can approach the necessary health authorities worldwide for the appropriate approval process to make this product available to all consumers." says Terry Howlett, President and CEO of Skinvisible.

Skinvisible Pharmaceuticals developed this antimicrobial hand sanitizer formula, primarily for the healthcare industry, using 2.25 percent Chlorhexidine as the active ingredient. Chlorhexidine is a non-toxic antiseptic that kills or inhibits the growth of disease-causing bacteria, viruses and other microorganisms, and is used for surgical scrub, skin wounds, germicidal hand rinse, and antibacterial dental rinse. Skinvisible's proprietary Invisicare(R) family of polymer delivery vehicles allow the formulations to stay on the skin for extended periods of time, as shown in this latest study.

According to the Center for Disease Control, the common seasonal influenza flu virus kills nearly one million people globally every year, and Skinvisible believes its Chlorhexidine Hand Sanitizer may offer an alternative to the alcohol-based hand sanitizers now used worldwide in the healthcare industry. Skinvisible's product also has been tested against a variety of bacteria of concern to the healthcare industry, including the Super Bugs, VRE and MRSA. The product will be undergoing further tests soon against other viruses, including Norovirus (Norwalk), Rhinovirus, Influenza A (H1 and H3), H2 and Influenza B.

About Invisicare(R)

At the heart of Skinvisible's patented technology and trademarked Invisicare(R) family of polymer delivery vehicles is its formula and process for combining hydrophilic and hydrophobic polymers into stable complexes in water emulsions. This allows formulated products using Invisicare(R) as their platform to remain on the skin for extended periods of time, thereby affording active agents a prolonged timeframe to perform their intended functions. Products utilizing Invisicare(R) have the proven ability to bond active ingredients to the skin for up to four or more hours. They are non-occlusive and allow normal skin respiration and perspiration while moisturizing and protecting against exposure from a wide variety of environmental irritants. When topically applied, these formulated products adhere to the skin's outer layers, forming a protective bond, resisting wash-off, and delivering targeted levels of therapeutic or cosmetic skincare agents to the skin. They allow enhanced delivery performance for a variety of skincare agents resulting in improved efficacy, longer duration of action, reduced irritation and lower dosage of active agent required. The "invisible" polymer compositions wear off as part of the natural exfoliation process of the skin's outer layer cells.

About Skinvisible Pharmaceuticals, Inc.

Headquartered in Las Vegas, Nevada, Skinvisible Pharmaceuticals is a research-and-development company that has formulated and patented innovative polymer delivery system technology and compositions for topical skin applications. Skinvisible's primary marketing and sales objective is to license its technology and sell its trademarked polymer delivery vehicle Invisicare(R) to established dermatological, cosmetic, skincare and pharmaceutical manufacturers.
