What are stability testing and regulatory compliance costs for cosmetics?

Stability testing (3–6 months of shelf-life data) costs $1,500–$5,000; safety assessments and claims substantiation add $2,000–$8,000. US cosmetics require ingredient declarations and claims compliance, but no pre-market approval. International markets (EU, China) demand additional testing. Budget 10–15% of total development costs for regulatory work.
