Our purple liquid soap colour is a water based colourant which achieves a shade from mauve to purple, depending on how much you use. For lighter tones, add a small amount at first to achieve your desired colour.
This colour is suitable for melt and pour and liquid soap, but can behave strangely in cold process and hot process. we suggest using ultramarine violet powder for cold process and hot process soap.
It can also be added to bath salts and bath bombs.
