1,2-Pentanediol
CAS 5343-92-0
1,2-Pentanediol, also known by the INCI name Pentylene Glycol, is a multifunctional diol used in cosmetic and personal care formulations as a humectant, solvent, and preservation-support ingredient. Public ingredient pages support a stronger draft profile around cosmetic use, purity, and storage handling, while final cosmetic-grade release values should still be confirmed through supplier TDS, COA, and regulatory documentation.
- Multifunctional diol for moisturizing and preservation-support systems
- Useful in skincare, haircare, and color cosmetic formulations depending on grade
- Can also serve as a solvent, solubilizer, and specialty synthesis intermediate
- Public cosmetic ingredient references support stronger positioning around moisture retention and formulation support
- Cosmetic-grade claims are still tied to final supplier documentation and regulatory review
