Caustic Soda Liquid (Lye) Supplier in India
VSVK Group supplies caustic soda liquid — also called caustic soda lye or sodium hydroxide solution — to soap, paper, textile, water-treatment and chemical-processing buyers across India. Caustic soda liquid is an aqueous solution of sodium hydroxide (NaOH, CAS 1310-73-2): a clear, strongly alkaline, corrosive liquid supplied in bulk by tanker.
As a Kanpur-based chemical importer, distributor and exporter operating since 1982 — and an authorised distributor for leading chemical principals — VSVK is positioned to supply bulk liquid caustic to industrial buyers, backed by its own fleet of 15 tankers, which is a real advantage for a product moved in liquid bulk.
Caustic soda liquid vs. flakes
This is the first decision a buyer makes, and the two forms are not interchangeable in handling:
- Caustic soda liquid (lye) is a ready-to-use aqueous solution at a defined concentration. It needs no dissolving step, is easy to meter and dose, and is ideal for plants that consume caustic continuously and can receive tanker deliveries. Handling is bulk-liquid and concentration-specific.
- Caustic soda flakes (which VSVK also supplies) are a solid ~98–99% form that must be dissolved in water before use. Flakes suit buyers who need long shelf storage, smaller quantities or don’t have tanker/bulk-liquid infrastructure.
Choosing liquid vs flakes comes down to consumption pattern, storage and receiving capability — VSVK can advise and supply either.
Key applications
- Soaps & detergents: saponification and neutralisation — a primary use.
- Pulp & paper: pulping, bleaching and de-inking.
- Textiles: mercerising, scouring and processing.
- Water & effluent treatment: pH correction and neutralisation.
- Chemical processing: feedstock and reagent across many syntheses.
- Alumina/metals and petroleum refining: process reagent.
- Food processing (food grade only): specific cleaning and processing uses, subject to grade confirmation.
Why the tanker fleet matters
Liquid caustic is delivered in bulk, and delivery capability is a genuine procurement factor. VSVK’s own 15-tanker fleet plus 20,000 sq. ft. of infrastructure supports reliable bulk liquid movement — a practical reason for continuous-use plants to consolidate supply with one partner rather than juggle multiple vendors.
Sourcing with VSVK Group
VSVK is a supplier, distributor and sourcing partner — not a manufacturer — with an authorised-distributor relationship to leading chemical principals. Buyers get one contact for enquiry, concentration confirmation, documentation and tanker delivery. This suits soap and detergent makers, paper and textile mills, and water-treatment operators needing dependable bulk liquid caustic.

Liquid caustic is traded at different concentrations (commonly in the 30–50% range), and the concentration affects freezing point, handling and dosing. VSVK does not state a fixed concentration on this page. *Available concentration should be confirmed with VSVK Group* for your application, so you receive material that matches your process.
Q: What concentration of caustic soda liquid do you supply?
Concentration is confirmed with VSVK for your application (VSVK does not pre-assume 32/48/50%).
Q: What’s the difference between caustic soda liquid and flakes?
Liquid (lye) is a ready-to-use solution; flakes are solid ~98–99% NaOH that must be dissolved. VSVK supplies both.
Q: Do you deliver liquid caustic by tanker?
Yes — VSVK operates its own tanker fleet for bulk liquid delivery; confirm location and quantity.
Q: Which industries use caustic soda lye?
Soaps/detergents, paper, textiles, water treatment and chemical processing, among others.
Q: Can you supply food-grade caustic?
Only where the required grade and documentation are confirmed for your use.
Q: How far can you deliver?
Delivery radius for liquid bulk is confirmed at enquiry.
