Description

γ-Propoxy-Sulfo-Lichenin CAS NO 163547-04-4 is a chemically modified polysaccharide derivative, specifically a sulfonated and propoxylated lichenin. This engineered biopolymer offers unique rheological and surface-active properties, making it a valuable functional additive in advanced material formulations. It is primarily sought by industries requiring high-performance, water-soluble polymers for stabilization, thickening, and controlled release applications.

Application

• As a viscosity modifier and stabilizer in pharmaceutical gels and topical formulations.
• In the development of advanced drilling fluid additives for the oil and gas industry to control fluid loss and rheology.
• As a functional excipient in controlled-release drug delivery systems.
• For enhancing the stability and texture of personal care products like creams and lotions.
• In specialty coatings and adhesives as a bio-based rheology control agent.
• As a dispersant and binder in ceramic and advanced material processing.
• Potential use in agricultural formulations for the encapsulation of active ingredients.

Quality Control

Our γ-Propoxy-Sulfo-Lichenin is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance and purity. Certificates of Analysis (COA) documenting key parameters such as degree of substitution, sulfate content, and viscosity are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
