Why should you view this course?

High SPF is the strongest trend in today’s sun care market. Also, products must meet UVA protection standards, a requirement that becomes more challenging the higher the SPF. Getting to such high SPF values is a lot more complex than getting the right amount of active - many different aspects of the formulation need to be optimized. Join this course and:


  1. Select optimal UV filters (oil/water-based; organic/ inorganic) to ensure a complete UVB & UVA protection

  2. Achieve high SPF targets by maximizing UV filters efficacy (using the right system of solvents, dispersants, photo-stabilizers, emollients...

  3. Ensure high efficacy of your sunscreen formulation (even distribution of actives) by optimizing all aspects including water-resistance, rheology & film-forming performance…
