Oleic Acid
- ester
- CAS 112-80-1
- IUPAC: (Z)-octadec-9-enoic acid
Natural monounsaturated fatty acid found in olive oil and animal fats. Low systemic hazard. Not a skin sensitizer. May cause mild eye or skin irritation at high concentrations; at 2–6% in conditioner formulas, no significant health concern.
Oleic acid is a naturally occurring monounsaturated fatty acid — the same compound that makes olive oil an effective skin emollient. In leather care products, it functions as a penetrating conditioning agent that softens and lubricates leather fibers, helping to restore suppleness in dry or weathered hides.
At the 2–6% concentrations found in leather conditioners, oleic acid presents no meaningful health concern. It is not classified as a sensitizer, carcinogen, or reproductive toxicant. Its biodegradability and natural origin make it one of the more environmentally preferred conditioning actives compared to petroleum-derived alternatives.
