Description

Pullulan is a linear, water-soluble polysaccharide polymer produced through the fermentation of starch by the fungus *Aureobasidium pullulans*. This unique biopolymer is valued for its exceptional film-forming, adhesive, and oxygen-barrier properties, making it a versatile and high-performance ingredient. It is widely utilized across the pharmaceutical, food, and cosmetic industries as a coating agent, binder, and encapsulating material. Its non-toxic, edible, and biodegradable nature aligns with the growing demand for sustainable and clean-label solutions.

Application

• Pharmaceutical Coatings & Capsules: Used as a film-forming agent for tablet coatings and to produce vegetarian (non-gelatin) capsules, providing excellent oxygen barrier properties to protect active ingredients.
• Food Industry: Functions as a thickener, binder, and glazing agent. It is used in edible films for food preservation, as a coating for nuts and confectionery, and to reduce oil uptake in fried foods.
• Cosmetics & Personal Care: Serves as a natural film-former in hair styling products, peel-off masks, and makeup, providing a smooth, non-sticky finish and moisture retention.
• Industrial Applications: Acts as a biodegradable adhesive and binder in various sectors, including water-soluble packaging, paper products, and as a flocculant.
• Encapsulation & Delivery Systems: Ideal for microencapsulation of flavors, fragrances, colors, and nutrients due to its ability to form strong, flexible films that control release.

Quality Control

Our Pullulan is manufactured under strict quality management systems. Each batch undergoes rigorous testing to ensure it meets the required specifications for purity, viscosity, and microbiological safety. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as assay, heavy metals, and loss on drying. We can supply grades compliant with Food Chemical Codex (FCC) and other relevant industry standards for pharmaceutical and food applications.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
