Ingredient - Sodium Palm Kernelate

Sodium palm kernelate is the sodium salt of palm kernel acid. It usually appears as a white paste or granules, and is derived from a mixture of fatty acids from palm (Elaeis guineensis) kernel oil. We use this ingredient in some of our bar soaps as a surfactant, to gently cleanse skin.

Sodium palm kernelate can be produced by reacting palm kernel fatty acids with a strong base, typically sodium hydroxide. This process can be undertaken with almost any fats and alkalis, and is known as saponification - the traditional method for creating soap. Sodium palm kernelate can be used in bar soaps and cleansers as a gentler alternative to some harsher surfactants.

Palm kernel oil (PKO) is derived from the kernels or seeds of the fruit, whereas palm oil (PO) is derived from the whole fruit. The two oils are compositionally different, with palm kernel oil having a much higher content of saturated fatty acids, particularly lauric acid.

Our policy on sustainable palm oil can be found on pages 26-31 of our 2018 Sustainability Report.
