Applications

Tensyra™ N-10 is a widely used non-ionic surfactant and detergent, valued for its versatility across pharmaceutical, industrial, and laboratory applications. Some of the key applications are as follows;

It is used in downstream processing (DSP) for biologic products as it facilitates the inactivation of lipid-enveloped viruses (such as HIV, HBV, and HCV) in biopharmaceutical manufacturing.
In Pharmaceutical applications it is used as solubilizer & emulsifier to improve solubility of poorly water-soluble APIs, as formulation aid in liquid and semisolid formulations and supports consistent drug delivery and stability. 
Aids cell lysis for the extraction of proteins or organelles, while also permeabilizing the membranes of live cells.
Acts as an excipient in pharmaceutical formulations to stabilize nanoparticles and colloids.
