Use at 1-3%. Can be used in both water (not purely water-based products as it is oil-based and so will not mix) and oil-based products. Add during Stage 3 for creams, lotions and balms.
Can be used in water products such as toners with the help of an emulsifier such as Emulsifan.
Can be added (without any heating required) to already-made products such as gels, lotions, creams, shampoos, liquid soaps and body washes.
