Protect Sensitive DEET Free Biodegradable Wipes use 20% micro-encapsulated Saltidin to provide a non greasy sensitive skin formula that has been clinically proven to be as effective as 50% DEET.  The unique time release technology used releases the repellent slowly, over the day, providing up to 12 hours protection from just one application. The length of protection provided is dependent on a variety of factors, including perspiration and activity. Protect Sensitive Biodegradable Wipes are sweat and splash resistant and suitable for children over 2, as well as pregnant women.
