About Potassium Hydroxide (KOH)

Buy potassium hydroxide (KOH, CAS 1310-58-3) from Alliance Chemical in technical and ACS grades. KOH is a strong caustic base used in alkaline cleaning, electrolysis, soap and detergent production, biodiesel processing, pH adjustment, and laboratory reagent work.

Products In This Collection

This collection includes potassium hydroxide flakes and grade-specific KOH products for industrial and laboratory buyers. ACS Grade is selected for reagent work, while Technical Grade supports production, maintenance, and process applications.

Common Applications

  • Electrolysis and green hydrogen: KOH is used as an alkaline electrolyte in selected electrolysis systems and related research or production workflows.
  • Soap and detergent production: Potassium hydroxide supports liquid soap, soft soap, and specialty detergent manufacturing.
  • Alkaline cleaning: KOH dissolves greases and organic soils in compatible cleaning systems and process equipment.
  • Laboratory reagent use: ACS KOH is used for titration, pH adjustment, and reagent preparation where grade control matters.

Grade & Selection Notes

Choose ACS Grade KOH for reagent or analytical work and Technical Grade for general industrial cleaning, process, and production applications. Confirm whether your process requires flakes, solution preparation, or a specific assay.

Safety & Handling

Potassium hydroxide is highly corrosive and generates heat when dissolved. Add KOH slowly to water, use PPE, and keep away from acids and incompatible metals. Review the Safety Data Sheets before use and follow your site-specific handling procedure.

Why Buy From Alliance Chemical

Most in-stock KOH orders ship in 1-2 business days. SDS and lot-specific COA support are available for grade-sensitive orders.

Frequently Asked Questions

What is potassium hydroxide used for?
KOH is used in alkaline cleaning, electrolysis, liquid soap production, biodiesel processing, pH adjustment, and reagent preparation.
How is KOH different from sodium hydroxide?
Both are strong caustic bases. KOH is often selected for liquid soap, electrolyte, and potassium-specific chemistry, while NaOH is common for general caustic soda applications.
Is potassium hydroxide corrosive?
Yes. KOH is highly corrosive and requires gloves, eye and face protection, compatible containers, and careful dilution practices.
Can I make a KOH solution from flakes?
Yes, but dissolution is exothermic. Add flakes slowly to water with mixing and cooling as needed.
Is ACS Grade KOH available?
Yes. ACS Grade KOH is available for reagent and laboratory applications where specification control is required.
