Glycols are a core group of industrial chemicals used across polyester, resins, coolants, pharmaceuticals, cosmetics, paints, inks, and specialty manufacturing. For buyers in Tamil Nadu and South India, Chennai is a practical sourcing hub because it combines port access, chemical warehousing, tanker movement, and fast road connectivity to major industrial clusters.
Supreme Petro Chemicals supplies commonly used glycol products in drum, IBC, and bulk quantities from Chennai. This guide explains the main glycol types, CAS numbers, applications, packaging options, and what procurement teams should clarify before requesting a quote.
What Are Industrial Glycols?
Industrial glycols are alcohol-based compounds with two hydroxyl groups. This chemical structure gives them useful properties: they are generally hygroscopic, miscible with water to varying degrees, and effective as humectants, solvents, freezing-point depressants, and intermediates in polymer and resin systems.
The word "glycol" is a broad commercial term. A purchase enquiry should always specify the exact product name, grade, CAS number where applicable, packaging, and intended application. MEG, DEG, propylene glycol, DPG, and PEG are not interchangeable products even though they sit in the same broad family.
Types of Glycols SPC Supplies
Mono Ethylene Glycol (MEG) — CAS 107-21-1
Mono ethylene glycol is a high-volume glycol used in polyester fibre, PET resin, antifreeze, coolants, and industrial heat-transfer fluids. It is typically sourced by buyers who need consistent bulk availability and clear documentation for plant-level consumption.
Diethylene Glycol (DEG) — CAS 111-46-6
DEG is used in unsaturated polyester resins, plasticizers, brake fluids, textile auxiliaries, printing inks, and some solvent systems. It has a higher boiling point than MEG and is selected where slower evaporation, humectancy, or resin compatibility is required.
Propylene Glycol (PG) — CAS 57-55-6
Propylene glycol is widely used in pharmaceuticals, cosmetics, personal care, food-adjacent formulations where the correct grade is specified, and industrial applications such as heat-transfer fluids. Buyers should clearly mention whether they require industrial, technical, USP, BP, IP, or food-grade material.
Dipropylene Glycol (DPG) — CAS 25265-71-8
DPG is valued in fragrances, cosmetics, printing inks, coatings, and specialty solvent blends. It is often selected for its low odour, solvency, and compatibility with fragrance compounds and resin systems.
Polyethylene Glycol (PEG) Grades 200-6000 — CAS 25322-68-3
PEG is supplied in multiple molecular-weight grades, commonly including PEG 200, 400, 600, 2000, 3350, 4000, and 6000. Lower-number grades are liquids used as solvents and humectants; higher-number grades are waxy or solid materials used in pharma, cosmetics, lubricants, binders, and processing aids.
Key Industries and Applications
Glycols appear in many industrial supply chains because they solve practical formulation problems: moisture control, viscosity adjustment, freezing-point control, carrier-solvent performance, and polymer building-block requirements.
- Polyester and resin manufacturing: MEG and DEG are used in polymer and resin systems where consistent specification is critical.
- Coolants and heat-transfer fluids: MEG and PG are used in antifreeze, chilled-water systems, process cooling, and thermal fluids, depending on performance and safety requirements.
- Pharmaceuticals and cosmetics: PG and PEG grades are used as excipients, solvents, humectants, and carriers when the correct grade and documentation are available.
- Paints, coatings, and inks: DEG, DPG, and selected PEG grades support flow control, drying profile, resin compatibility, and humectancy.
- Textiles and auxiliaries: Glycols can be used in finishing, dyeing auxiliaries, and moisture-management formulations.
- Fragrance and personal care: DPG and PG are common carriers for fragrance compounds and personal-care formulations.
Packaging and Bulk Supply Options
Packaging depends on the product, grade, order size, and buyer handling setup. Common options include 200-litre drums for regular plant consumption, 1,000-litre IBC tanks for higher-volume users, and bulk tanker loads for large continuous requirements. PEG solid grades may be supplied in bags or drums depending on the grade and source packing.
Before requesting a quote, mention the exact glycol, quantity, packaging preference, delivery location, required grade, and any documentation such as MSDS/SDS, CoA, or manufacturer-origin details. This helps avoid mismatches between industrial, technical, pharma, and food-grade requirements.
Why Source Glycols from Chennai
Chennai is well positioned for glycol sourcing in South India. It has port access for imported chemicals, established chemical storage corridors, and strong road connectivity to manufacturing hubs in Chennai, Sriperumbudur, Ambattur, Hosur, Coimbatore, Andhra Pradesh, and Karnataka.
For procurement teams, the advantage is not only location. A Chennai-based supplier can coordinate stock checks, documentation, drum or IBC dispatch, and urgent delivery windows more efficiently than distant supply points. For materials like MEG, DEG, PG, DPG, and PEG grades, local availability can reduce production downtime when forecasts change.
FAQ
What is the MOQ for glycol products?
MOQ depends on the specific glycol, grade, packaging, and current stock position. Drum, IBC, and bulk quantities may have different minimums. Share your required product, quantity, and delivery location for an accurate response.
Can SPC supply pharma or food-grade glycols?
Selected grades such as propylene glycol and PEG may be available in pharma or food-related specifications depending on stock and manufacturer documentation. Always state the required standard, such as USP, BP, IP, or food grade, during enquiry.
How do I get a quote for MEG, DEG, PG, DPG, or PEG?
Send the product name, CAS number if known, grade, quantity, packaging preference, and delivery location. SPC will confirm availability, documentation, packaging, and dispatch options.
