Trial overview
Official title: Determination of SPF, before and after immersion in water, for a cosmetic product at minimum of 3 subjects
Trial description: The Present study will determine the preliminary Sun Protection Factor (SPF) and resistance to water of the test product in at least 3 study subjects.The study consists of the application of an investigational product (IP) on study subjects back in order obtain a minimum of 3 subjects with valid results for each group, tested with 40 and 80 minutes of immersion. This is a screening study for preliminary evaluation of SPF in vivo. The study will be performed with two groups. The first one will perform the research under dry conditions and with a 40-minute immersion in water, and a second one will perform the research under dry conditions and with an 80-minute water immersion. Once the product has presented resistance to water at 40 min, the sponsor will decide if the test at 80 min of immersion will be conducted, which is the second part of the protocol The study of SPF measurement follows the ISO 24444: 2010 Cosmetics -- Sun protection test methods - In vivo determination of the sun protection factor (SPF) and the COLIPA Guidelines for Evaluating Sun Protect Water Resistance
