Best full spectrum UV protection mineral blends for use in spray on sun block formulas?
Looking to make prototypes of a spray on mineral sunscreen that could be put into production later on. Companies such as Umicore sell such blends, and BASF has their Z-COTE full spectrum zinc oxide to make formulation easier and help ensure you’re making an effective product (which has been a problem with a lot of “natural” mineral sun blocks, from badger brand to the honest company).
1. Have you worked with any (ideally ecocert) mineral dispersion blends that could easily plug into such a formula?2. Do you have any recommendations as to what emulsifiers to use in a spray-on system?
