Stearic Acid Triple Pressed C18-70% Min
At Gayanis Oleochemicals, our Stearic Acid Triple Pressed C18-70% is a long-chain saturated fatty acid possessing an 18-carbon backbone, procured from natural vegetable palm oil. Its chemical formula is C₁₈H₃₆O₂, and its systematic designation is Octadecanoic acid.
Stearic acid is obtained via the hydrolysis of common vegetable and animal oils and fats. The resultant fatty acids are then subjected to crystallization or distillation. Pressing techniques are employed to isolate the solid saturated fatty acids from the liquid unsaturated fatty acids. Cosmetic-grade stearic acids are typically pressed two or three times to attain different concentrations.
