Sodium hydroxide (NaOH), is an essential alkali used in the traditional cold process method of soapmaking. Available in 500 g and 1 kg sizes, this high-purity lye is ideal for home and artisan soap crafters who require consistent results and reliable saponification. Our Sodium hydroxide is packaged in resealable, clearly labelled containers for safe handling and convenient storage.

This compound plays a critical role in transforming oils and butters into solid soap bars through the chemical process of saponification. When accurately measured and blended with fats, caustic soda forms the base structure of soap, leaving no residue in the final cured product. It is suitable for use with a variety of soapmaking oils, including tallow, coconut, olive, and palm, and supports the creation of hard, long-lasting bars with excellent lather.

Accurate and measured use of sodium hydroxide ensures both safety and performance in soap recipes. For soapmakers who formulate in small or medium batches, these pack sizes allow for flexibility while maintaining batch consistency. Because it is used up entirely during the chemical reaction, only proper use and handling are required to ensure a safe, skin-friendly result. This product is intended strictly for professional, cosmetic, or household soapmaking use and should always be handled with appropriate protective equipment.
