Description

2,3,4,5-Tetrastearoyl-D-Glucitol is a fully esterified derivative of D-glucitol (sorbitol) with stearic acid. This compound serves as a high-performance, non-ionic surfactant and emulsifier, valued for its stability and hydrophobic character. It is primarily utilized in the formulation of specialty cosmetics, personal care products, and as a processing aid in industrial applications where robust, lipophilic properties are required.

Application

• Cosmetic & Personal Care Formulations: Acts as a key emulsifier, opacifier, and viscosity modifier in creams, lotions, and makeup products.
• Pharmaceutical Excipient: Used as a lipophilic carrier and stabilizer in topical ointments and controlled-release drug delivery systems.
• Food-Grade Additives (where specified): Functions as an emulsifier and anti-caking agent in certain food processing applications.
• Industrial Lubricants & Release Agents: Serves as a component in mold release formulations and specialty lubricants due to its waxy nature.
• Plastic & Polymer Additive: Employed as an internal or external lubricant and anti-static agent in polymer processing.
• Textile & Fiber Processing: Used as a softening agent and water repellent finish for fabrics.

Quality Control

Our 2,3,4,5-Tetrastearoyl-D-Glucitol is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and saponification value are available upon request. We can support compliance requirements for various application standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve stability. Keep away from strong oxidizing agents.
