Frequently Asked Questions

What is propylene glycol used for?

Propylene glycol works as a humectant and carrier in pharmaceuticals, cosmetics and food, and goes into unsaturated polyester resins, antifreeze and coolant formulations, and liquid detergents. The pharmacopoeial grade we stock suits excipient and personal-care applications.

What is the CAS number and HSN code of propylene glycol?

Propylene glycol has CAS number 57-55-6 and HSN code 29053200. Its chemical name is 1,2-propanediol (propane-1,2-diol).

Is this USP grade propylene glycol?

Yes. We stock pharmacopoeial-grade propylene glycol meeting IP, USP, BP and EP, with assay NLT 99.5% w/v (as C3H8O2, by GLC). It is sourced from Manali Petrochemicals Limited (ISO 9001 & 14001 certified), and our published specification comes from the MPL COA (Ref QR/QA/32) cross-checked against MPL's published IP/USP specification.

Is propylene glycol the same as mono propylene glycol (MPG)?

Yes. Propylene glycol (PG), mono propylene glycol (MPG) and 1,2-propanediol all name the same chemical, CAS 57-55-6 — in chemicals, PG stands for propylene glycol. Dipropylene glycol (DPG) is a different product, which we list separately.

How is propylene glycol packed, and can you supply it in Chennai?

We supply propylene glycol in HDPE/MS drums of 215 kg net from our Redhills warehouse in Chennai, with dispatch across South India. Order sizes depend on packaging and current stock — call or WhatsApp +91 86087 80096 for a quote.

How should propylene glycol be stored?
