Description

Cutin CAS NO 54990-88-4 is a natural, high-molecular-weight biopolyester that forms the structural framework of the plant cuticle, providing a critical hydrophobic barrier. This compound matters for its unique combination of biodegradability, biocompatibility, and protective film-forming properties, making it a valuable bio-based raw material. Industries focused on sustainable coatings, advanced encapsulation, and green material science need it to develop next-generation products with enhanced environmental profiles.

Application

• Biodegradable Coatings & Films: Used as a base polymer for creating protective, water-resistant, and environmentally friendly coatings for seeds, fruits, and packaging materials.
• Controlled-Release Systems: Serves as a matrix material in agricultural and pharmaceutical formulations for the encapsulation and slow release of active ingredients like fertilizers, pesticides, or drugs.
• Cosmetic & Personal Care: Incorporated into skincare formulations (e.g., creams, lotions) for its film-forming and moisturizing properties, helping to improve skin barrier function.
• Biomedical Materials: Investigated for use in tissue engineering scaffolds and wound dressings due to its biocompatibility and support for cell adhesion.
• Food Preservation: Applied as an edible coating to extend the shelf life of fresh produce by reducing moisture loss and gas exchange.
• Specialty Adhesives & Binders: Utilized in the development of bio-based adhesives with specific hydrophobic and binding characteristics.

Quality Control

Our Cutin is produced and tested under strict quality management protocols to ensure batch-to-batch consistency and performance. Quality parameters, including polymer composition, acid value, and solubility profile, are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing purity, physical characteristics, and relevant specifications is provided with every shipment to support your quality assurance processes.

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). The material is hygroscopic (moisture-sensitive); ensure the container is kept sealed to prevent moisture absorption, which can affect properties.
