Lavender & oatmeal CP soapmaking kit: without sodium hydroxide*
Cold-process Soapmaking Kits
Lavender & oatmeal CP soapmaking kit
* Please note: For the time being, we are unable to ship kits and packs with sodium hydroxide, commonly called caustic soda, or caustic soda pearl.
Sodium hydroxide (caustic soda) can be bought from the following places:
Bunnings (Glitz caustic soda)
Make sure it is 99% pure and is not liquid. DO NOT buy Draino. It is diluted and won't make soap.
Make your own REAL cold-process soap bars and have the satisfaction and security of knowing what ingredients you are using.
Each kit will make approximately 10 100g bars of pure and natural soap. The kit comes complete with all the ingredients necessary, except sodium hydroxide, easy step-by-step instructions and a silicon loaf mould.
A stick blender is essential and a thermometer is recommended.
The refill pack: No instructions; no mould; no kitbox, no sodium hydroxide
Some people are surprised that soap contains sodium hydroxide.
All soap does. It cannot be made without it.
Companies generally disguise this unpleasant bit of news and don’t list sodium hydroxide alone as an ingredient.
So tallow mixed with sodium hydroxide becomes sodium tallowate; sodium hydroxide mixed with olive oil is sodium oleate, etc.
When soap is made with the correct proportions of ingredients there is no sodium hydroxide left in the bar so is safe to use.
If too much sodium hydroxide is used or the soap not mixed enough the soap will be brittle, it may have streaks of sodium hydroxide in it and it must not be used.
Soap will be too soft if not enough sodium hydroxide is used.
Ingredient proportions are critical and each oil needs a different percentage of sodium hydroxide to break it down into soap.
