Oil INCI names / Castor oil

Castor oil INCI name

Castor oil has two INCI names depending on what you make with it: it keeps its botanical name in a lotion or balm, and takes a saponified name in cold-process soap, where the oil reacts with lye and the oil itself is no longer in the finished bar.

In lotions, balms, leave-on and rinse-off productsRicinus Communis Seed Oil
In cold-process soap (saponified with NaOH)Sodium Castorate
Superfat share in soap (unreacted)Ricinus Communis Seed Oil
Also entered ascastor, castor seed oil

Glossary citation: Sodium Castorate #22988; Ricinus Communis Seed Oil #21433 (Commission Decision (EU) 2019/701 on EUR-Lex).
