Test performed on 10 volunteers, by comparison of pre-wash and post-wash SPF. The treatment includes two washes, one in salt water, performed by irroration with 1M NaCl solution by a pressureless drop shower, and one in fresh water. If the reduction of protection is greater than 50% the product isn’t considered to be “Salt Water Resistant”.
In vivo test on 10 subjects. Comparison between SPF of sun product and the reduction on protection cause of double sand static contact of 20 minutes in this sequence: contact, techanical cleaning, contact and final mechanical cleaning before the exposure to the solar multiport simulator. If the reduction of protection is mayor than 50% the product isn’t “sand resistant”.
Determination of the percentage of water resistance of a sunscreen product on PMMA plates with measurements before and after washes in controlled conditions. The preliminary test requires confirmation through in vivo tests.
