Description

Sucrose Tetrastearate is a non-ionic surfactant and emulsifier derived from sucrose and stearic acid. This compound is valued for its excellent emulsifying properties, biocompatibility, and biodegradability, making it a preferred choice in formulations requiring mild and safe ingredients. It is primarily utilized by manufacturers in the personal care, cosmetics, pharmaceuticals, and food industries to create stable, high-quality emulsions and improve product texture.

Application

• Cosmetic & Personal Care Emulsions: Acts as a primary or co-emulsifier in creams, lotions, and conditioners for stable oil-in-water systems.
• Pharmaceutical Formulations: Used as an excipient in topical creams, ointments, and oral suspensions to enhance drug delivery and stability.
• Food Industry Additive: Functions as an emulsifier and stabilizer in certain food products, contributing to texture and shelf-life.
• Industrial Applications: Serves as a surfactant in specialty cleaning products, lubricants, and textile processing aids.
• Biodegradable Product Formulations: An ideal ingredient in "green" or eco-friendly products due to its plant-based origin and environmental profile.

Quality Control

Our Sucrose Tetrastearate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, ester composition, and residual solvents are available upon request to support your quality assurance protocols.

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 performance.
