Description

12-Hydroxystearamide is a high-purity, long-chain fatty acid amide derivative of 12-hydroxystearic acid. This specialty chemical serves as a versatile intermediate and performance additive, valued for its unique combination of hydrophobic character and a reactive hydroxyl group. It is essential for manufacturers in the polymer, lubricant, and personal care industries seeking to modify material properties such as slip, anti-blocking, and viscosity. The compound, identified by CAS NO 7059-49-6, is supplied to meet the stringent quality demands of global industrial applications.

Application

• Polymer Additive: Functions as an effective internal and external lubricant, slip agent, and anti-blocking agent in PVC, polyolefins, and engineering plastics.
• Cosmetics & Personal Care: Acts as an opacifying agent, viscosity modifier, and stabilizer in creams, lotions, and makeup formulations.
• Lubricants & Greases: Utilized as a thickener and performance additive to enhance the structural stability and water resistance of lithium and calcium complex greases.
• Textile & Fiber Industry: Serves as a softening agent and spin finish component to improve fiber processing and hand feel.
• Ink & Coating Additive: Imparts matting effects, improves scratch resistance, and aids in pigment dispersion.
• Chemical Synthesis: A key intermediate for producing esters, surfactants, and other derivatives with tailored hydrophobic properties.

Storage

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