Description

n-Carboxybutyl Chitosan is a water-soluble, chemically modified derivative of chitosan, featuring a carboxybutyl group attached to the glucosamine unit. This modification significantly enhances its solubility and bioadhesive properties compared to native chitosan, making it a highly functional biopolymer for advanced applications. It is particularly valuable in the pharmaceutical, cosmetic, and biomedical industries where biocompatibility and specific functional performance are critical. Our supply of n-Carboxybutyl Chitosan CAS NO 125265-78-3 ensures consistent quality and reliable performance for your formulation needs.

Application

• Pharmaceutical Drug Delivery: As a functional excipient for controlled-release and targeted drug delivery systems, leveraging its mucoadhesive and film-forming properties.
• Cosmetic & Personal Care Formulations: Used in skincare products, hair care, and creams as a moisturizing, film-forming, and viscosity-enhancing agent.
• Wound Healing & Tissue Engineering: Employed in the development of advanced wound dressings, hydrogels, and scaffolds due to its biocompatibility and ability to support cell growth.
• Biomedical Coatings: Applied as a coating material for medical devices and implants to improve biocompatibility and reduce adverse reactions.
• Nutraceutical Encapsulation: For the encapsulation of sensitive active ingredients, vitamins, and probiotics to enhance stability and bioavailability.
• Agricultural & Horticultural Uses: As a component in seed coatings and foliar sprays to improve plant growth and provide controlled release of agrochemicals.
