Description

n-Hydroxymethyl-Stearamide is a versatile fatty acid amide derivative, specifically an N-(hydroxymethyl)amide of stearic acid. This compound is valued for its dual functionality, acting as a reactive intermediate and a performance additive in various industrial formulations. It is primarily sought by manufacturers in the polymer, textile, and personal care industries for its ability to modify surface properties and enhance material performance.

Application

• As a key internal and external lubricant and slip agent in the processing of PVC, polyolefins, and engineering plastics.
• As a water-repellent and softening agent in textile finishing and fabric coatings.
• As a chemical intermediate for the synthesis of more complex surfactants and emulsifiers.
• As a component in cosmetic and personal care formulations, such as creams and lotions, for its emollient properties.
• As an anti-blocking and anti-fogging agent in plastic films and packaging.
• In the production of waxes and polishes to improve gloss and durability.

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