Description

Cellulose Caprate is a cellulose ester derivative where capric acid (decanoic acid) is esterified onto the cellulose backbone, creating a material with unique hydrophobic and film-forming properties. This compound is valued for its ability to modify the physical characteristics of formulations, offering controlled release and enhanced stability. It serves as a key functional ingredient for industries such as pharmaceuticals, where it acts as an enteric coating polymer, and in advanced material science for creating specialty films and barriers.

Application

• Pharmaceutical Enteric Coatings: Used as a polymer to create acid-resistant coatings for tablets and capsules, ensuring targeted drug release in the intestinal tract.
• Controlled Release Matrices: Serves as a rate-controlling excipient in sustained-release solid dosage forms.
• Specialty Films & Barriers: Employed in the production of water-resistant and biodegradable films for packaging or technical applications.
• Microencapsulation: Acts as a wall material for encapsulating active ingredients, flavors, or fragrances to improve stability and handling.
• Cosmetic & Personal Care: Functions as a film-forming agent and texture modifier in nail polishes, sunscreens, and skin care products.
• Industrial Binders & Coatings: Used in formulations requiring specific adhesion, water repellency, or modified drying characteristics.
