Water Resistant (at 80 mins)

Water-resistant sunscreens are formulated to maintain their level of sun protection even when exposed to water, sweat, or humidity.  
 
Our clinical testing service evaluates the in vitro water-resistant capacity of a sunscreen sample, measuring the retention of SPF value after 40 minutes of water exposure. The 40-minute and 80-minute benchmarks are the standard criteria for sunscreen water resistance claims. 
 
This testing allows cosmetic companies to confidently label their products as water-resistant and inform consumers of how long they can expect the product to maintain its effectiveness in water. By providing reliable, scientific evidence of their product's water-resistant capacity, cosmetic companies can ensure that their products deliver the promised protection to consumers in various water activities.
