Buyer intent coverage
Caustic soda (sodium hydroxide) flakes and pearls — what it is, where it is used, how it is chosen
Caustic soda is sodium hydroxide supplied in solid form as flakes, pearls or prills. It is a strong alkali used across chemical processing, pulp and paper, water treatment, soap and detergent manufacture and industrial cleaning.
Primary uses
- Neutralising acidic process and waste streams
- Saponification in soap and surfactant manufacture
- Alkaline CIP cleaning of process equipment
- pH correction in water and effluent treatment
Applications
- Pulp, paper and textile processing
- Soap, detergent and surfactant manufacture
- Municipal and industrial effluent neutralisation
- Chemical synthesis and pH control
- Alkaline degreasing and CIP systems
Advantages
- Solid flakes and pearls are shipped and stored without the freezing risk of liquid caustic in Canadian winter conditions
- High alkalinity per unit weight compared with carbonate alkalis
- Dissolves readily to make solution on site at the required strength
Limitations to consider
- Strongly corrosive — requires trained handling, PPE and compatible materials of construction
- Highly exothermic on dissolution; solution make-up must be controlled
- Strongly hygroscopic; absorbs moisture and CO2 from air
How to choose the right grade
- Choose flakes or pearls based on dissolving equipment and dust tolerance
- Confirm the minimum NaOH assay your process requires
- Confirm packaging your site can receive and handle safely
- Confirm the transport classification requirements for your destination
Typical grades
- Industrial / technical grade
- Higher-assay grades where the process requires
Comparable materials — how Caustic soda (sodium hydroxide) flakes and pearls sits against alternatives
- Potassium hydroxide — where the potassium ion is required
- Soda ash (sodium carbonate) — milder alkali, different dosing profile
- Liquid caustic solution — where on-site dissolution is not wanted
Comparable-material reference. Grade selection is confirmed at RFQ against your process.
Procurement coverage
How to specify, order and receive Caustic soda (sodium hydroxide) flakes and pearls
Written for procurement, quality and technical buyers in Canada and the United States. No numeric price, MOQ, stock or lead-time value is published — those are confirmed per shipment in the quotation and against the confirmed batch.
How buyers specify at RFQ
- Physical form (flakes, pearls, prills)
- Minimum NaOH assay and carbonate / chloride limits
- Packaging format
- Destination and transport-classification requirements
Packaging options (industry-standard)
- Lined multi-wall bag — the standard solid-caustic format
- Steel or plastic drum where a rigid closed container is required
- Packaging options and available pack sizes are confirmed with each quotation.
Storage & handling
- Store sealed in a dry area away from acids and moisture
- Use corrosion-resistant handling equipment and full PPE
- Add caustic to water, never water to caustic
Documentation available
- Technical data sheet (TDS) for the offered grade
- Safety data sheet (SDS) in the format required for Canadian import
- Certificate of analysis (COA) against the confirmed batch
- Documentation is confirmed per batch at quotation; availability depends on the grade and supplier offered.

Technical & procurement detail
Flakes vs pearls — which form do you actually need?+
Flakes are the most common and lowest-cost form and dissolve quickly when added directly into water. Pearls are micro-spheres that flow freely, generate less dust and are preferred for automatic dosing systems and biodiesel transesterification. Both grades have identical 99% chemical assay.
Safe handling at the customer site+
Caustic soda is strongly exothermic when dissolved in water — always add caustic to water (never water to caustic), use PPE, eye protection and a controlled feed rate. Each shipment ships with a current bilingual (EN/FR) SDS that meets WHMIS 2015 / GHS requirements.
Logistics across Canada+
Most LTL orders dispatch from our Ontario logistics partner the same week to anywhere in Ontario. Quebec, Maritimes and Western Canadian customers take FTL or FCL container loads with rail intermodal to Calgary and Vancouver.
Frequently asked questions
What is the purity of your caustic soda?+
Both our flakes and pearls are 99% minimum NaOH with low chloride and iron content. Full COA ships with every lot.
Do you provide SDS in French for Quebec customers?+
Yes — every shipment to Quebec includes a bilingual EN/FR SDS that meets WHMIS 2015 / GHS regulations.
Can you supply caustic soda by the container?+
Yes — 20-ton FCL container loads ship from our Ontario logistics partner anywhere in Canada with rail intermodal options for Western Canada.
Is there a minimum order?+
We sell from a single 25 kg bag for small workshops up to multi-container monthly contracts for industrial buyers.
