Thanks for the information. I'm not a fan of any of the many chemical concoctions that we're all encouraged to use on our body - internally and externally. I've always been suspicious of sunscreen, therefore, I've never used it, nor have my children. Apart from that, I've often wondered what cumulative affect - if any - all that sunscreen is having on the water in the lakes and oceans, as people apply it to their body, and then go swimming.
