Sunscreen formulating/ Reducing whitecast
Hi all, I’ve been formulating a sunscreen recently and I can’t give every single exact detail but the following is the basis of my formulation:
I am finding a significant white cast at 2% TiO2 and even when I reduce the Tinosorb M to 4%, when they’re together. I have tried making creams at 2% TiO2 and 6% Tinsorb M alone (2 separately) and they are completely fine, but when put together it’s a disaster.
Does anyone have any advice in reducing the white cast that comes with it? Or anything else in my formulation that is glaringly ridiculous?
P.S Using ethanol as a solvent is not an option for me!
P.P.S. We are looking to formulate something that is at least SPF50 PA+++
