Advanced Biopolymer Science
Chitosan Beyond Conventional Applications
At Promecens, we have developed a high-purity chitosan with a degree of deacetylation (DDA) exceeding 90%, delivering enhanced bioactivity, solubility, antimicrobial efficacy, and sustainability compared to traditional chitosan. Our chitosan is an advanced biopolymer derived from renewable sources, offering a biodegradable and biocompatible alternative to synthetic polymers used in cosmetics, pharmaceuticals, food preservation, and industrial applications.
Through precision molecular engineering, Promecens has optimized chitosan’s moisture retention, antimicrobial properties, and structural integrity, positioning it as a next-generation material for high-value applications in healthcare, clean technology, and sustainable manufacturing.
Understanding Chitosan: Molecular Structure & Functional Properties
Chitosan is a naturally occurring polysaccharide obtained by the deacetylation of chitin, which is found in the exoskeletons of crustaceans, fungi, and insects. Its unique polymeric structure imparts remarkable physicochemical properties, making it a critical biomaterial in biomedical, pharmaceutical, and environmental technologies.
Chitosan Chemistry
Molecular Structure of Chitosan
Chitosan consists of β-(1→4)-linked D-glucosamine (deacetylated units) and N-acetyl-D-glucosamine (acetylated units). The degree of deacetylation (DDA) is a crucial determinant of its functional properties:
Chitosan Purity & Performance
- High-Purity Chitosan (DDA >90%) → Superior solubility, bioactivity, and antimicrobial potency.
- Conventional Chitosan (DDA ~70-85%) → Reduced functional efficacy due to lower deacetylation levels.
By engineering ultra-pure chitosan with a high degree of deacetylation, Promecens ensures greater chemical reactivity, enhanced solubility in acidic environments, and increased biological activity, enabling applications across cosmetics, pharmaceuticals, and biodegradable packaging.
Functional Properties
