Our Castile Liquid Soap Base is a great way to create your own natural liquid soaps such as hand soap, body wash, facial cleanser, foamer liquid, shower gel, natural shampoo or even shower goo/slime. It may be cold processed or hot processed. Since the liquid soap base/paste is already fully saponified, there is no need to hot-process the base unless you want to hasten the process. Just add water, colour and fragrance!
To cold process this base, simply add pure water to the soap base and leave overnight or for 4-8 hours. Once the soap base is completely liquefied and homogeneous add your colour and fragrance.
To hot process this base, boil pure water and add to the soap base. You may optionally cook the solution to further hasten the process. Once the soap base is completely liquefied, homogeneous and under 45C, add your colour and fragrance.
Use within a week, or add a preservative that is stable in alkaline environments.
We also sell 500ml plastic bottles that can be used to store your liquid soap.
