Liquid Caustic Soda NaOH 45%

Name: Liquid caustic soda NaOH 45%
Brand: Hóa Chất Lộc Thiên
SKU: NAOH-45L
Availability: InStock

Liquid caustic soda NaOH 45% (sodium hydroxide solution, CAS 1310-73-2) is a mid-to-high strength alkali for textile mercerising, pulp cooking, industrial cleaning, metal pretreatment and pH control in industrial wastewater. Loc Thien supplies B2B bulk (IBC, drum, tanker where available) with COA/MSDS on request — hotline 0979 891 929.

Compared with NaOH 50%, the 45% grade often freezes less readily in typical Vietnamese warehouse weather, which can simplify storage and pumping. Always confirm concentration on the lot COA and design dilution heat/safety for your plant.

Liquid caustic soda NaOH 45% — Loc Thien B2B supply

What is NaOH 45% liquid caustic soda?

Sodium hydroxide solution at about 45% w/w is a clear to slightly cloudy corrosive liquid. It is the same chemical family as flake/pearl caustic and as NaOH 32/48/50 liquid grades — the difference is concentration, density, freeze behaviour and how much water you must add on site.

Industrial applications (B2B)

Textile & dyeing: mercerising / alkali treatment of fibre and fabric lines that specify liquid caustic.
Pulp & paper: cooking and bleaching support alkali demand (site recipe).
Metal & plating prep: hot alkaline degreasing baths after proper dilution and process control.
Food & seafood utilities (CIP): diluted NaOH circuits for equipment cleaning where the plant SOP allows caustic CIP — not food ingredient use.
Water / WWTP: pH lift and alkali make-up; coordinate with coagulants (PAC, Fe salts) on the same train.
Resin / demin: regeneration of anion exchange resin after engineering dilution.

Handling, dilution and safety

Treat as a corrosive industrial chemical — PPE, eyewash, trained operators.
Dilution is exothermic: add caustic to water with agitation; never dump water into concentrated alkali carelessly.
Use compatible tanks, pumps and seals rated for NaOH; label lines clearly.
Keep SDS on the floor; spill kits and neutralisation plan per site HSE.
Do not mix blindly with acids or incompatible oxidisers — follow your process engineer.

Packing, storage, delivery

Common B2B packs: drums, IBC and bulk tanker enquiry where logistics allow. Store sealed, cool as practical, away from acids and aluminium. Loc Thien delivers to factories and industrial parks nationwide (HCM, Binh Duong, Dong Nai and other KCN) — state the delivery point on the RFQ for freight and lead time.

FAQ — liquid NaOH 45%

What is the CAS number of sodium hydroxide?

CAS 1310-73-2. The commercial product is an aqueous NaOH solution; concentration is stated on the COA (target about 45%).

Why choose NaOH 45% instead of 50%?

Many plants pick 45% for a balance of strength and storage/pumping behaviour. NaOH 50% can crystallise or thicken more readily in cooler conditions. Your process alkali demand and tank farm design should decide — we can quote 32/45/48/50 against the same RFQ.

Is NaOH 45% the same as caustic soda flake?

Same chemistry (NaOH), different form. Flake/pearl is solid; 45% is a ready solution. Dissolving flake on site needs water, heat management and time; liquid 45% is already dissolved at concentration.

Can I get COA and MSDS?

Yes. Lot COA and MSDS are provided on request for B2B shipments.

Do you publish a retail price or sell small consumer packs online?

No public retail cart or list price. Loc Thien quotes wholesale by volume, packing and delivery point. Hotline 0979 891 929 or request a quote.

How do I order bulk liquid caustic soda 45%?

Send estimated tonnage, packing (drum/IBC/bulk), delivery industrial park/province and any COA requirements. We return a B2B quotation without online checkout.
