Stearic Acid Triple Pressed C18-50% Min
Stearic Acid Triple Pressed C18-50% is a long-chain saturated fatty acid featuring an 18-carbon backbone, sourced from natural vegetable palm oil. Its chemical formula is C₁₈H₃₆O₂, and its systematic designation is Octadecanoic acid. Stearic acid is derived through the hydrolysis of common vegetable and animal oils and fats.
The resulting fatty acids undergo crystallization or distillation. Pressing techniques are utilized to separate the solid saturated fatty acids from the liquid unsaturated fatty acids. Cosmetic-grade stearic acids are typically pressed two or three times to achieve varying concentrations.
