Summary

Moisturizing Emollient Humectant Anti-inflammatory Antimicrobial Antioxidant Skin conditioning Masking Perfuming

Science

Mechanism of Action

This ingredient forms an occlusive barrier on the skin's surface, effectively reducing transepidermal water loss (TEWL) and sealing in moisture, thereby promoting skin suppleness. Its prominent component, ricinoleic acid, contributes anti-inflammatory, antimicrobial, and antioxidant benefits, which can help soothe irritations, mitigate inflammation, purify the skin, and support healthy pore and tissue function.

While generally considered safe and non-sensitizing for most individuals, some may experience isolated allergic reactions or sensitivities, thus patch testing is recommended. The FDA has also approved castor oil for use as a stimulant laxative.
