Dear R&D Officer
I would like to ask questions on the following issues:
1. If you want a liquid sunscreen product, use it as a "sprayer sunscreen" (non-aerosol) with SPF 50 and PA+++.
According to the recipe guideline at myskin recommended web page.
1.Water Solvent 44.00 %
2. Cyclomethicone Emolients 15.00 %
3. Titanium Dioxide 15nm Liquid Sunscreen 25.00 %
4. Zinc Oxide 35nm Liquid Sunscreen 15.00 %
5. Mild Preserved Eco Preservative 1.00%
question
1. The above formula, when done, is in the form of use as a "liquid" and can be used as a "spray spray" (non-aerosol) to have SPF 50 and PA+++ or not? No, unless it is recommended as a substitute.
2. If you want to use PMMA Booster (SPF/Color Booster) to boost the SPF/PA, use a proportion of 3% appropriate or not, and if applied, can reduce Zinc oxide or Titanium Dioxide or not?
3. If ordering PMMA Booster , please advise that SPF verification service is available, how to proceed? Please advise.
Thank you for your answer.
