Description

N,n-Bis(Hydroxymethyl)Stearamide is a high-purity, non-ionic chemical intermediate derived from stearic acid. This compound is valued for its ability to act as a versatile building block, imparting properties like hydrophobicity, lubrication, and chemical resistance to final formulations. It is essential for manufacturers in the polymer, personal care, and textile industries seeking to enhance product performance and stability.

Application

• As a key intermediate in the synthesis of specialty surfactants and emulsifiers.
• As a slip agent and internal lubricant in polymer processing (e.g., PVC, polyolefins).
• As a chemical modifier in textile auxiliaries to provide water repellency and softness.
• As a component in personal care formulations, such as creams and lotions, for its emollient properties.
• As a corrosion inhibitor and additive in industrial lubricants and metalworking fluids.
• In the production of paper coatings to improve surface finish and printability.
