Question
What is the maximum percentage of Zinc Oxide that can be used in lip products?
Answer
# Zinc Oxide Usage in Lip Products
Based on general cosmetic regulations, the maximum allowed percentage of active Zinc Oxide in cosmetic formulations, including lip products, is typically up to 25%. This limit is set by regulatory bodies like the FDA to ensure safety.
The specific amount of Zinc Oxide you should use in a lip product formulation can vary depending on the desired Sun Protection Factor (SPF) level and the type of Zinc Oxide being used (e.g., powder form or a dispersion). Always refer to the supplier's recommended usage rate for the specific Zinc Oxide product you are using, and ensure the final formulation adheres to local cosmetic regulations regarding active sunscreen ingredients.
