I'm into doing things myself. From making candles to making decals right through to making soaps and furniture.
Decent soap your looking at 24 hours to make but around 4-6 weeks for them to dry.
The most important ingredient is the Caustic soda. Ensure you get pure sodium hydroxide and not something caustic soda based (which a lot of things marketed as "caustic soda" are).
Try this simple soap:
900ml water.
295g caustic soda
615g coconut oil
800ml sunflower oil
800ml olive oil
Ensure you wear goggles, apron rubber gloves and use plastic no metal buckets and moulds.
Stir the soda slowly into the water and whisk. It'll get bloody hot so watch your surfaces. While doing this get your oils in a large pan and warm them up ensuring to stir that too but with a different spoon!
Finally stir them all in together with the soda and water and KEEP stirring for around 40 mins or until the colour and texture changes of the mixture.
Here you add your scents and textures. Oats give the soap a rough texture and orange and myrrh essential oils are good for starters (you'll need around 20g of essence). Turmeric gives it antibacterial and antifungal properties.
Anyway, when happy just pour the mixtures into your moulds and cover them and leave for 24 hours to set. Once they have set then take them out the plastic and leave for a few weeks for the caustic soda to fully dissolve.
This is the dangerous step as if you use the soap too soon then the caustic soda will cause burns on your skin. If your impatient then get some universal indicator solution or litmus papers to check how far along the bars are.
Once their close to neutral then you can start cutting them up onto bars for use.
