i have been reading up on the ZNO product, the 24hrs on the hands, even after washing the hands with soap i am finding troubling, people will be applying the ZNO product two or three times a day if not more, each time adding bonding layers to the skin, of tin pins as they describe, what happens when the accumulated layers are one someones hands, and they can not remove them with soap and water, it states on the ZNO site that the ingredient will stay on clothes even after they have gone through the wash 10 times. I am sure they have a great product, but the bonding of the substance to the surface of the skin, i would not use it, would definitely use the surface spray on hard surfaces, but if i am putting something on my hands and clothes i want to know i can wash it off if required. and i would also like to know the bonding agent, that is not a chemical and does not react with water?
