As formulators you will be looking to meet a range of SPF and UVA labelling requirements and our newly launched Solaveil Calculator is an easy to use tool that provides data on inclusion levels and achievable SPF using our Solaveil range of safe and effective inorganic UV filters.
Watch our video to explain how best to use the calculator and the ease of obtaining valuable results for your sunscreen formulation.
I know the SPF I want to achieve
The Solaveil Calculator gives you the SPF for single ingredients and provides you with quick information about what levels to use.
I know the inclusion level of inorganic UV filter
The Solaveil Calculator allows you to look in more detail at the efficacy of Solaveils. You can use this for combinations of Solaveils, combining the values for SPF or UVAPF. Please note SPF and UVAPF are absolute values so can be added. Other UVA criteria, like the critical wavelength and UVA/UVB are not additive.
Disclaimer; The Solaveil Calculator is not a replacement for in vivo testing. The Solaveil calculator gives a indication of theoretical SPF and is a starting point for your formulation development.
