Question
What is the recommended use of Polysilicone-15 in sunscreen formulations? What is its function, and what is the estimated SPF when used alone at 10% concentration?
Answer
Based on the previous discussion, Polysilicone-15 is generally recommended to be used in conjunction with other sunscreen ingredients to enhance the overall SPF value and improve the texture of the formulation, making it lighter. If used alone at a concentration of 10%, the estimated SPF is around 25. However, the actual SPF can vary depending on other components in the formula, and laboratory testing is recommended for accurate determination.
