A Laboratory Method for Measuring the Water Resistance of Sunscreens
By: Berislav Markovic, Donna Laura and Mark Rerek,…
A new laboratory in vitro method for the measurement of sunscreen water resistance uses spectrophotometric analysis of a model skin substitute before and after 80-minute immersion. It gives good correlation with the FDA’s 80-minute immersion SPF results (very water resistant). The method is especially good for screening new formulations or water-resistant technologies.

Formulating Water-resistant Sunscreen Emulsions
By: Ken Klein, Cosmetech Laboratories
Note that today we aren't permitted to use the term "waterproof" since the FDA believes that this term implies an absolute-it never washes off-and feels that consumers might be inclined not to reapply sunscreen after swimming or perspiring. So, we must now use the term "very water resistant" in its place.
