Description

Sodium 1-Carboxylatoethyl Stearate is the sodium salt of a fatty acid ester derivative, functioning as a versatile anionic surfactant and emulsifier. This compound is valued for its ability to modify surface tension and stabilize formulations, making it a critical performance additive in demanding industrial processes. It is primarily sought by manufacturers in the personal care, textile, and polymer industries for its emulsifying and conditioning properties.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and opacifying agent in creams, lotions, and hair conditioners.
• Textile Processing: Used as a softening agent, lubricant, and antistatic agent for synthetic and natural fibers.
• Polymer & Plastics Industry: Serves as an internal and external lubricant and mold release agent during polymer processing.
• Industrial Cleaners & Detergents: Functions as a surfactant and wetting agent in specialized cleaning formulations.
• Paper & Pulp Manufacturing: Employed as a dispersant and softening agent to improve paper quality and processability.
• Leather Processing: Used in fatliquoring and softening stages to impart suppleness to leather goods.

Quality Control

Our Sodium 1-Carboxylatoethyl Stearate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment. We can supply grades compliant with relevant standards for food, cosmetic, and industrial applications upon request.

Storage

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