Features

Description

Essentially Natural Caustic Soda Lye is sodium hydroxide, a highly caustic alkali used in soap making to trigger saponification when combined with oils and fats. It is a raw process ingredient rather than a finished cosmetic component, and it is essential for making true hard soap by cold or hot process methods.

Used correctly in a tested soap recipe, the active lye is consumed during saponification. This is a specialist soap-making material and must be handled with strict safety procedures.
