Sunscreen Formulation: SPF 70 PA++++ and Mousse-like Powdery Texture

Evaluation of Your Sunscreen Formulation

Based on the formulation you provided, here is an evaluation regarding the SPF/PA level and the desired texture:

• SPF 70 PA++++: Achieving a high SPF like 70 and PA++++ requires precise formulation and validation through testing or simulation (such as the BASF Sunscreen Simulator mentioned by the staff). While your formula includes significant concentrations of UV filters (Zinc Oxide, DHHB, OMC), it is difficult to guarantee this specific high level of protection without proper testing or simulation. The staff's previous response also suggested the SPF might not reach this level.
• Mousse-like, Powdery Texture: Your formulation includes ingredients specifically chosen to provide a powdery feel and a non-greasy finish, such as PowderCream™, BB Micro Silk™ (Silica Powder), and LipidSoft™ Dry. These ingredients are highly effective in creating a dry, smooth, and powdery texture upon application. The combination with the emulsifier (Light Cream Maker) could also contribute to a lighter, potentially mousse-like consistency before application.

Conclusion: The formula is very likely to achieve the desired powdery texture. However, the claim of SPF 70 PA++++ needs to be verified through laboratory testing or simulation tools like the BASF Sunscreen Simulator.
