CAS · 112-80-1
Product Overview
Oleic acid丨CAS 112-80-1 is a monounsaturated omega-9 fatty acid with the chemical formula C₁₈H₃₄O₂. It naturally occurs in animal and vegetable fats, particularly in olive oil, where it is a major component (up to 80%). Oleic acid appears as a pale yellow or colorless oily liquid at room temperature. Due to its non-toxicity, biodegradability, and chemical versatility, oleic acid is extensively used in industries ranging from food and cosmetics to pharmaceuticals, lubricants, and surfactants.
