Natural waxes that add hardness and water resistance to soap
Natural waxes add hardness, water resistance, and longevity to handmade soap bars. Beeswax creates an incredibly hard bar and helps with unmolding, while candelilla wax is a vegan alternative. Waxes require careful handling — they raise trace temperature, can cause false trace, and should be used sparingly (typically 1-5%). Always add to melted oils and use a higher water ratio.
