Insufficient Data CAS 6720-16-7 / PERFUMING

2-Nonylcrotonaldehyde is an unsaturated aldehyde compound primarily utilized as a fragrance ingredient in cosmetic formulations. This oil-soluble perfuming agent contributes to specific scent profiles but lacks documented skincare bioactivity mechanisms. Due to its aldehyde structure, it requires careful formulation to prevent oxidative degradation over time.

Summary
