I'm doing a project on formulation of topical sunscreens. While looking
through references, a few questions have been brought up:
1.) Specifically, how is SPF related to absorbance rate?
2.) How do non-active excipients affect SPF?
3.) Any recent info on PABA being mutagenic?
4.) Any recent developments at all in formulation of topicals?
Thanks in advance for any info anybody might have.
