Hewitt: There is an element of truth in [that statement]. Certainly, the performance of a sunscreen product cannot reliably be predicted just from the active ingredients. SPF is strongly dependent on the formulation, in particular on the spreading and film-forming properties of the product. The experience of the sun care formulator is, therefore, invaluable in creating new products, and raw material suppliers should be contacted for advice on how to make the best of their ingredients. Croda, for example, has extensive documentation to assist formulators in using its inorganic sunscreen dispersions.
