Potassium Hydroxide (KOH) is the essential alkali used to create liquid soaps, cream soaps and shaving soaps. Supplied in both 500 g and 1 kg sealed containers, this high-grade potassium hydroxide is ideal for cold process and hot process soapmakers looking to produce soft or fluid soaps with exceptional lather and skin-feel. Its fine flake form ensures quick dissolution in water and consistent saponification when blended with oils or butters.

Unlike sodium hydroxide, which produces firm bar soap, potassium hydroxide yields a soap with a paste or liquid consistency, making it perfectly suited for pump bottles, foaming cleansers or whipped body soaps. It's especially useful in castile-style liquid recipes and allows for creative control over clarity, viscosity and moisturising properties. This flexibility makes it a preferred choice for makers of natural, handmade personal care products.

With pack sizes designed for both small batch formulation and mid-scale production, our potassium hydroxide gives you the freedom to develop multiple soap types while ensuring safety and consistency. It is intended for use in cosmetic and household soapmaking only, and must be handled with protective gear and measured accurately. Always store in a cool, dry, airtight container to preserve performance and prevent moisture absorption.
