Product Description
Stearic Acid 98% - PVC Stabilizer Lubricant, Cosmetic Emulsifier, Rubber Processing Aid
Stearic acid (chemical formula C₁₇H₃₅COOH) is a saturated long-chain fatty acid primarily refined from natural fats and oils through hydrolysis and fractional distillation. Available as white flakes, beads, or powder, this versatile compound features both hydrophobic long alkyl chains and hydrophilic carboxyl groups, enabling multiple functions including lubrication, emulsification, softening, and plasticization.
Core Applications & Industry Uses
Plastics & Rubber Processing
PVC Processing: As a primary external lubricant, stearic acid forms a protective film between polymer melt and equipment, reducing viscosity, minimizing friction, preventing sticking, and enhancing mold release and surface finish. Its metal salts are essential components of PVC heat stabilizers.
Rubber Manufacturing: Functions as an internal lubricant and softener during mixing and molding, improving processability, flow characteristics, and filler dispersion while facilitating product release.
Cosmetics & Personal Care
Cream & Lotion Base: The soap formed by reacting stearic acid with bases serves as a classic emulsifier for O/W (oil-in-water) formulations including vanishing cream, cold cream, facial cleansers, and hand creams, providing stable texture and smooth application.
Surfactant Production: Base material for manufacturing various stearate salts and ester surfactants used as emulsifiers, thickeners, and pearlescent agents.
Food & Pharmaceutical Industries
Food Applications: Food-grade stearic acid (compliant with GB 1886.101 standards) serves as a coating agent, lubricant, and antifoaming agent for candies, baked goods, and processing aids.
Pharmaceutical Uses: Employed as a tablet lubricant and sustained-release matrix, and in ointment preparations.
Additional Industrial Applications
Metalworking: Component in lubricants for wire drawing and stamping operations.
Polishes & Coatings: Used in manufacturing crayons, shoe polish, floor wax, and paint flatting agents.
Candle Production: Enhances melting point and hardness characteristics of paraffin wax.
Product Specifications & Grading
Stearic acid is graded into Triple Pressed, Double Pressed, and Single Pressed categories based on iodine value, acid value, saponification value, color, and purity parameters. Triple Pressed offers the highest purity and whitest color.
Our stearic acid features high purity (98% or higher), consistent white color, stable acid value, and well-defined melting range. We supply industrial, cosmetic, and food-grade products to manufacturers across multiple industries.
We provide comprehensive formulation advice and technical support to help clients optimize processing performance and enhance final product quality.
