Frequently Asked Questions

What is pentylene glycol used for?

Pentylene glycol (1,2-pentanediol, CAS 5343-92-0) is a diol used as a solvent and multifunctional additive. Industrial uses include cosmetics and personal care, industrial/professional/consumer cleaning and maintenance products, air care products, polishes and wax blends, and inks and toners.

Is pentylene glycol the same as propylene glycol?

No. Pentylene glycol is 1,2-pentanediol (a five-carbon diol, C5H12O2), while propylene glycol is 1,2-propanediol (a three-carbon diol). They are different molecules with different chain lengths and solvency/humectancy profiles.

Is pentylene glycol an alcohol?

Yes. It is a diol, meaning it carries two hydroxyl (-OH) groups on a five-carbon chain (molecular formula C5H12O2). That makes it a glycol/polyol used as a solvent and formulation additive.

What is the CAS number and HS code for pentylene glycol?

Pentylene glycol carries CAS 5343-92-0 and typically classifies under HS heading 2905.39 (other diols). Confirm the import classification for your jurisdiction with your broker.

How is bulk pentylene glycol packaged, and how do I get a price?
