Description

Sucrose Heptastearate is a high-purity, non-ionic surfactant derived from sucrose and stearic acid. This compound is valued for its excellent emulsifying, stabilizing, and conditioning properties, making it a versatile ingredient in demanding formulations. It is primarily used by manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking natural-derived, mild, and effective multi-functional additives.

Application

• Cosmetic & Personal Care Emulsions: Acts as a primary or co-emulsifier in creams, lotions, and sunscreens, providing stable oil-in-water systems.
• Hair Care Conditioners: Imparts excellent conditioning, detangling, and softness in shampoos, conditioners, and hair masks.
• Pharmaceutical Topicals: Used as an emulsifier and stabilizer in medicated creams, ointments, and dermatological preparations.
• Food-Grade Emulsifiers: Suitable for food applications where a sucrose ester-based emulsifier is required, though specific grade compliance must be verified.
• Industrial Surfactant: Serves as a wetting agent, dispersant, or emulsifier in specialty chemical and agrochemical formulations.
• Biodegradable Formulations: An ideal choice for "green" or eco-friendly product lines due to its plant-derived, biodegradable nature.

Quality Control

Our Sucrose Heptastearate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, ester composition, acid value, and moisture content are available upon request. We can support compliance with relevant standards for cosmetic (ISO 22716) and cGMP guidelines.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
