Stearic Acid 1801, Alternative Names: Octadecanoic Acid, Stearic Acid.
It is a high-grade satura ted fatty acid. The pure product appears as glossy white soft flakes, with a relative density of 0.9408 (at 20°C), a melting point ranging from 69°C to 70°C, a boiling point of 383°C, and a refractive index of 1.4299 (at 80°C). The industrial-grade product is a white or slightly yellow granular, which is a mixture of stearic acid and palmitic acid, containing a small amount of oleic acid and a faint beef tallow-like odor. It is very slightly soluble in cold water, easily soluble in benzene, toluene, chloroform, carbon tetrachloride, carbon disulfide, amyl acetate, etc., and also soluble in ethanol and acetone.
Stearic acid is widely distributed in nature and exists in many vegetable oils and animal fats.
Long-chain saturated alkyl group (-C₁₈H₃₇): Provides stability, hydrophobicity, and lubricity, and is responsible for physical effects (such as film formation, friction reduction, and steric hindrance).
Carboxyl group (-COOH): Offers reaction activity, and can react with alkalis, metal oxides, etc., to form derivatives (such as stearates). It is responsible for chemical effects (such as emulsification, vulcanization activation, and saponification).
It improves the molding quality and production efficiency of plastic products. Meanwhile, as a release agent, it extends the service life of molds. Additionally, it is used as a vulcanization accelerator to enhance the physical properties of rubber products.
It is one of the key raw materials for manufacturing soap-based products such as soaps and detergents. In skin care products like face creams and lotions, it plays the dual role of an emulsifier and a thickener.
It stabilizes pigment dispersion and prevents pigment sedimentation.
As a metal lubricant, it effectively reduces friction between metals and molds, prolongs the service life of molds, and lowers production costs.
It improves the cycle performance and service life of lithium-ion batteries, and enhances the photoelectric conversion efficiency of photovoltaic modules.
As a product derived from natural oils and fats, stearic acid 1801 has excellent biodegradability and environmental friendliness, conforming to the requirements of environmental protection and sustainable development.
Relying on its unique physical and chemical properties, stearic acid 1801 plays an important role in numerous industries. With the growth of market demand and the expansion of emerging fields, it shows broad development prospects. Our products, featuring high purity, environmental friendliness, and multi-functionality, will effectively meet customers' strict requirements in various application scenarios. We look forward to cooperating with customers to jointly promote the innovative application of stearic acid 1801 in more fields and achieve a win-win situation.
