Description

n-(2,3-Dihydroxypropyl)Stearamide is a non-ionic surfactant and emulsifier derived from stearic acid and glycerin. This compound matters for its excellent emulsifying, stabilizing, and conditioning properties, making it a versatile additive in formulations requiring smooth texture and stability. It is primarily needed by manufacturers in the personal care, cosmetics, and industrial lubricant sectors for creating high-performance products.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and thickener in creams, lotions, and hair conditioners, providing a rich, non-greasy feel.
• Industrial Lubricants & Metalworking Fluids: Serves as a friction modifier and emulsifier, enhancing lubricity and stability in water-based formulations.
• Textile & Fiber Processing: Used as a softener and antistatic agent to improve the handle and processing of synthetic fibers and fabrics.
• Agricultural Adjuvants: Functions as a surfactant and dispersant in pesticide and herbicide formulations to improve spray coverage and efficacy.
• Plastics & Polymer Additives: Employed as an internal and external lubricant and anti-blocking agent in polymer processing.
• Paper Coatings: Acts as a softening and release agent in specialty paper coatings and processing.

Quality Control

Our n-(2,3-Dihydroxypropyl)Stearamide is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
