Description

Glyceryl Stearate is a versatile, non-ionic surfactant and emulsifier derived from glycerin and stearic acid. This compound is essential for creating stable, uniform emulsions and modifying texture in a wide range of industrial and consumer formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, pharmaceutical, and food industries seeking reliable performance and ingredient compatibility. Its multifunctional properties make it a cornerstone for product developers aiming to enhance consistency, shelf life, and sensory appeal.

Application

• Primary emulsifier and opacifying agent in creams, lotions, and cosmetic formulations.
• Stabilizer and texture modifier in pharmaceutical ointments, creams, and topical delivery systems.
• Food-grade emulsifier and anti-caking agent in baked goods, confectionery, and whipped toppings.
• Co-emulsifier and viscosity builder in industrial cleaning products and polishes.
• Lubricant and release agent in plastic and polymer processing.
• Key ingredient in hair conditioners and styling products for its conditioning and smoothing effects.

Quality Control

Our Glyceryl Stearate is produced under strict quality management systems. We offer grades compliant with relevant industry standards, including Food Chemical Codex (FCC) and cosmetic-grade specifications. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept in its original, unopened packaging until use to prevent caking and degradation. For long-term storage, consider using desiccants or a controlled humidity environment.
