Description

Cellobiose Octanonanoate is a fully esterified derivative of the disaccharide cellobiose, where all eight hydroxyl groups are substituted with nonanoate (pelargonate) ester groups. This chemical modification significantly enhances its lipophilicity and stability, making it a valuable specialty intermediate for advanced material synthesis. It is particularly sought after by R&D and production teams in the pharmaceutical, cosmetic, and specialty polymer industries for creating novel biodegradable materials, controlled-release systems, and high-performance additives.

Application

• Pharmaceutical Excipient: Used as a lipophilic matrix former or coating agent for controlled-release and enteric-coated dosage forms.
• Cosmetic Ingredient: Serves as a non-greasy emollient, skin-conditioning agent, and stabilizer in high-end skincare and makeup formulations.
• Polymer Plasticizer: Acts as a bio-based, biodegradable plasticizer for cellulose acetate, nitrocellulose, and other specialty polymers to improve flexibility and processability.
• Specialty Surfactant Intermediate: A key precursor for synthesizing novel sugar-based non-ionic surfactants with tailored HLB values.
• Lubricant & Release Agent: Employed in industrial applications as a component of mold release agents and high-temperature lubricants.
• Analytical Chemistry Standard: Used as a reference standard in chromatographic analysis for carbohydrate and ester profiling.

Quality Control

Our Cellobiose Octanonanoate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity assay and identity confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment to guarantee traceability and batch-to-batch consistency.

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). Keep the container tightly sealed in a dry environment to prevent moisture absorption, which can affect product stability and performance.
