What’s the purpose of using carrier oils for soap making?
Carrier oils like coconut oil and castor oil are great assets to your homemade soap.
Not only do they add more skin-loving benefits - like extra moisture and nourishment thanks to their vitamins and fatty acids - but they also allow your soap bars to last a lot longer and feel a lot firmer.
Provided your chosen carrier oils have a published saponification value, they can be an incredibly useful and arguably necessary tool for keeping your soaps in good nic.
