Description

Flexible Collodion CAS NO 8050-70-2 is a specialized, film-forming solution of pyroxylin (nitrocellulose) in a mixture of ether and alcohol, often modified with camphor and castor oil to impart elasticity. This product is valued for its ability to form a flexible, protective, and adherent film upon drying, which is crucial for medical and technical applications. It is primarily required by manufacturers in the pharmaceutical, medical device, and specialty coatings industries for wound care, protective dressings, and as a carrier for topical medications.

Application

• Medical & Pharmaceutical: As a primary component in medicated collodion for wart and corn removal, and as a protective, flexible film-forming agent for wound dressings and surgical sealants.
• Dermatology & Topical Delivery: Used as a vehicle or occlusive dressing to enhance the penetration and efficacy of topical active pharmaceutical ingredients (APIs).
• Medical Device Manufacturing: Applied as a protective, flexible coating for sensitive skin areas, for securing small dressings, or in the prototyping of certain wearable medical devices.
• Laboratory & Histology: Employed as a protective coating for tissue samples on microscope slides or for sealing specimen containers.
• Specialty Adhesives & Coatings: Utilized in niche industrial applications requiring a fast-drying, clear, and flexible adhesive or protective layer for delicate materials.
• Cosmetics: Occasionally used in special-effect makeup and theatrical applications to create flexible, skin-safe prosthetics or seals.

Quality Control

Our Flexible Collodion is manufactured and tested to meet stringent quality standards, including relevant pharmacopoeial monographs where applicable. Each batch is subjected to rigorous analytical testing for key parameters such as film characteristics, drying time, residue, and solvent composition. A Certificate of Analysis (COA) documenting purity, performance, and safety is provided to ensure compliance with your specific application requirements and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile nature, keep containers tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
