Castile Soap is a mild traditional soap made only from the pure vegetable oils of coconut and olive. Using caustic potash (potassium hydroxide) instead of caustic soda (sodium hydroxide), as used in making hard bar soaps, Castile Soap is light and liquid. It is suitable for all types of cleansing needs – baths, showers and on – and is suitable for all skin types and ages. Castile Soap also serves as an excellent shampoo. Just remember to use a slightly acid rinse after shampooing, as any minerals in ‘hard’ tap water can leave a slight soap film on the hair after rinsing. A teaspoon or more of vinegar or lemon juice in 100ml of water makes an effective rinse. Add essential oils as desired.
