Sodium hydroxide solutions with CAS number 1310-73-2 are widely used for drain cleaning, soap making, pH adjustment, and various industrial and laboratory processes. This guide highlights five suitable products, explains who each is best for, and notes practical cautions to help buyers compare options quickly.
The table below offers a quick snapshot of the featured products by concentration and container size to assist a fast comparison.
| Product | Concentration | Container | Grade |
|---|---|---|---|
| Alliance Chemical – 20% Technical Grade (4 Gallon) | 20% w/w | 4 Gallon Case Jug | Technical Grade |
| Alliance Chemical – 20% Technical Grade (1 Quart) | 20% w/w | 1 Quart Bottle | Technical Grade |
| Alliance Chemical – 30% ACS Grade (4 Gallon) | 30% w/w | 4 Gallon Case Jug | ACS Reagent Grade |
| Alliance Chemical – 30% ACS Grade (1 Gallon) | 30% w/w | 1 Gallon Jug | ACS Reagent Grade |
| Alliance Chemical – 10% ACS Grade (1 Quart) | 10% w/w | 1 Quart Bottle | ACS Reagent Grade |
Alliance Chemical 20% Technical Grade – 4 Gallon Case
Best for industrial applications requiring a bulk supply of sodium hydroxide at 20% technical grade. The 4-gallon jug is suited for maintenance labs, manufacturing lines, and professional drain-cleaning workflows. The product is clearly identified with CAS 1310-73-2 and a straightforward formula: NaOH. Caution: handle with appropriate eye and skin protection; even at 20%, it is caustic and should be used with ventilation and PPE.
Alliance Chemical 20% Technical Grade – 1 Quart
Best for small-scale projects, classroom experiments, or initial testing of formulations that require 20% NaOH. The 1-quart bottle is convenient for controlled usage and formulation trials. Best for users who need periodic, moderate amounts rather than bulk supply. Limitation: smaller packaging increases the frequency of replacements for ongoing heavy-use tasks.
Alliance Chemical 10% ACS Grade – 1 Quart
Best for precise analytical work or applications where ACS-grade purity is essential but a lower concentration is acceptable. The 10% ACS grade solution is suitable for pH adjustment, certain synthesis tasks, and sensitive lab procedures. Caution: ACS-grade products may carry stricter handling expectations; ensure clean glassware and equipment to avoid contamination.
Alliance Chemical 30% ACS Grade – 4 Gallon
Best for high-strength cleaning and chemical synthesis that benefit from a 30% ACS-grade solution. The larger 4-gallon jug supports steady production or multiple workstations. Choose this if you need stronger concentration with ACS-grade purity. Limitation: higher concentration increases caustic risks; follow safety guidelines and use proper PPE.
Alliance Chemical 10% Technical Grade – 1 Gallon
Best for ongoing projects with moderate usage, offering a balance between concentration and packaging size. The 1-gallon container is convenient for labs with multiple small tasks or businesses testing new formulations. Caution: ensure compatibility with materials that contact the NaOH solution to avoid container damage.
Buying Guide: Key Purchase Considerations
- Grade choice: ACS Grade offers higher purity ideal for analytical work, while Technical Grade suffices for cleaning and general synthesis. Consider the required purity level for your application.
- Concentration needs: Higher concentrations reduce handling volume but increase caustic risk. Select a strength that matches your process requirements and safety capabilities.
- Packaging and scale: For continuous use or multiple workstations, larger jugs (e.g., 4 Gallon) reduce reordering. For testing or limited tasks, 1 Quart or 1 Gallon bottles fit smaller budgets and spaces.
- Container materials: Ensure compatible containers and tools with caustic NaOH to prevent degradation or contamination of the product.
- Safety and handling: Always use PPE, work in a well-ventilated area, and store upright away from incompatible materials. Follow local regulations for caustic chemicals.

ACS Grade indicates a higher standard of chemical purity suitable for analytical uses and precise formulations.
Yes, 20% technical grade NaOH is commonly used for drain cleaning, but always follow safety guidelines and product instructions.
For a small lab, a 1 Quart or 1 Gallon bottle is convenient and reduces waste if usage is limited.
Protective gloves, eye protection, lab coat or apron, and proper ventilation are essential when handling caustic sodium hydroxide solutions.
Mixing different concentrations is possible but requires careful calculation and testing to ensure the final pH and safety are appropriate for the intended use.
Store upright in a cool, dry place, kept away from acids and reactive metals. Ensure containers are closed tightly to prevent moisture uptake.
