5. Outlook and developments
Having validated the concept on syntheses of a few hundred grams, it is now necessary to transfer the synthesis protocol to larger scales (kilograms and hundreds of kilograms). Some technologies are not suitable for industrial scale. We therefore need to set up a synthesis protocol using technologies used in industry, and adjust the parameters to obtain a material with similar properties. A cost study must also be carried out to assess the profitability of these new ingredients.
Stable encapsulation of active ingredients in silica has been validated for the PBSA UV filter, and can be extended to other active ingredients for cosmetic or other applications, taking into account the relevant specifications.
