Castor Seed Oil
A rich botanical oil that helps condition, soften, and maintain moisture for smooth, supple-feeling skin.
Why This Ingredient Matters
Castor Seed Oil is a distinctive botanical emollient composed predominantly of ricinoleic acid, a fatty acid that gives the oil its characteristic rich texture and conditioning properties.
It helps soften and smooth the skin and is particularly useful in oil-based cleansing and replenishing formulations.
Why Formulation Matters
Botanical oils are not interchangeable. Their different fatty-acid compositions influence texture, spreadability, cleansing
performance, and how a finished formula feels on the skin.
Castor Seed Oil's unusually high ricinoleic-acid content gives it properties that differ from lighter botanical oils. When blended with complementary oils, it can contribute richness, conditioning, and effective
oil-based cleansing without requiring the formula to depend on a single lipid.
