From the linked article it is unclear if the chemicals are absorbed into the body or not. From the horse's mouth:

"Kite Patch is designed for clothing, not skin. A few news articles did get it wrong – but our technology is designed to be placed on clothing, baby carriers, backpacks, Camelbacks and other outdoor gear (for outdoor enthusiasts), etc. Kite is NOT a skin patch."
