Description

Peg-2 Stearamide Carboxylic Acid is a nonionic surfactant and emulsifier derived from stearic acid and ethylene glycol. This compound is valued for its ability to provide excellent emulsification, conditioning, and viscosity control in complex formulations. It is primarily used by manufacturers in the personal care, cosmetics, and industrial surfactant sectors seeking stable, high-performance ingredients.

Application

• Primary Emulsifier in creams, lotions, and ointments for personal care and cosmetic products.
• Viscosity Modifier and Stabilizer in hair conditioners, styling gels, and skin care emulsions.
• Co-emulsifier and Dispersant in industrial formulations, including textile processing aids and polymer emulsions.
• Conditioning Agent providing softness and manageability in hair care and fabric softener compositions.
• Base Material for the synthesis of more complex esterquats and other specialty surfactants.
• Additive in agricultural adjuvant formulations to enhance the spreading and adherence of pesticides.

Quality Control

Our Peg-2 Stearamide Carboxylic Acid is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise chemical and physical specifications, including identity, purity, and acid value. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
