Frequently Asked Questions
What is the full form of PG in chemicals?
PG stands for Propylene Glycol, also known as Propane-1,2-diol, Monopropylene glycol (MPG). Its CAS number is 57-55-6. Supreme Petro Chemicals supplies Propylene Glycol (PG) to manufacturers from Chennai.
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?
