Why should you attend?

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.


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

  2. Maximize UV filters efficacy using the right system of solvents, dispersants, photostabilisers, emollients...

  3. Optimize water-resistance, rheology & film-forming performance of your formulations (O/W, W/O, spray...)

Very good overview and connection of known and new topics reg. formulating sun care products.

Susann W. , from Evonik Industries AG

Very good! I needed a structured overview in order to be more efficient when developing High SPF formulas. This course was very beneficial!

Cloe C. , from Clariant

Very concise yet comprehensive and relevant. A well structured and well presented course that has given me great insight into current formulation trends, as well as great ideas for the direction of my future formulations. This course has brought me right back up to speed for a mere hour of my time - truly excellent!

David C. , from Aldwin Paige

The course helped me to understand the reason of our formulations. I realized that there are a lot of things that we have to consider, not only the filters and their solubility.

Mayra C. , from Laboratorios Genesse

Very good! Explanations are clear and it is very helpful for me to formulate new suncare products

Sanela K. , from kanebo paris office

Excellent! The course was very comprehensive for all aspects of the formulation
