Isopropyl alcohol

High-purity 99% isopropyl alcohol (IPA) is a fast-evaporating solvent that dissolves many non-polar residues and leaves minimal residue. Commonly used for surface prep, cleaning, and as a soaper’s tool.

Why formulators use it

• Quick evaporation for streak-free wipe-downs and fast dry-times.
• Excellent solvent for oils, waxy residues, and pigment wetting.
• Handy in soapmaking for popping bubbles, layer adhesion, and reducing soda ash.

How to use

Cold-process (CP) soap

• Immediately after pour, lightly mist the surface with 99% IPA to help reduce soda ash.

Melt & pour (M&P) soap

• Pop bubbles: Fine mist over the surface straight after pour.
• Layer adhesion: Lightly spritz set layers just before pouring the next.
• Disperse colourants: Pre-wet micas/oxides/clays with a little IPA, then stir into melted base.

General formulation & making

• Surface prep: Wipe benches, tools, and containers before you start and after clean-up.
• Pigment wetting: Use small amounts to pre-disperse powders before adding to oil or M&P bases.
• Always test on a small area first; some plastics/finishes may be sensitive.
