INCI Ricinus Communis Seed Oil

Emollient / Film-Forming Oil Hydration & Barrier

What it is & what it does

Castor Oil is a thick emollient oil rich in ricinoleic acid.
WHAT IT IS: Castor Oil is a thick emollient oil rich in ricinoleic acid.

HOW IT WORKS: It forms a flexible, glossy film that reduces dry feel and improves surface softness. Its viscosity also helps protect and coat skin, lips, hair or nails.

WHY ITS ROLE MATTERS: Plant oils generally contain fatty acids and minor compounds that can soften skin and support the emollient phase. Different botanical species and extraction methods produce different lipid profiles; nutritional studies on eating the plant cannot establish the effects of applying its oil topically.

A REALISTIC EXPECTATION: The most direct practical role is comfort and softness, while specific antioxidant or anti-aging claims need evidence for the tested oil or product.

Information approach Consumer-friendly summaries are informed by established cosmetic ingredient references such as INCIDecoder and Paula’s Choice Ingredient Dictionary, while avoiding turning ingredient-level evidence into medical claims about the finished product.
