The document discusses substantiating claims for cosmetic products. It defines what claims are, provides examples of different types of claims, and explains which claims require substantiation and product integrity package (PIP) support. Performance claims and certain formula claims need to be supported by evidence in the PIP to prove the effect claimed and ensure all claims are truthful. Marketing, product development, and product testing are responsible for substantiating claims. Subjective and objective claims require different types of substantiation based on consumer opinions or instrumental measurements.
