Scogin® IN2420

Scogin® IN2420 is a naturally derived alginate polymer sourced from sustainably managed brown seaweed farms. It is typically used as a binder, gelling agent, and thickener. It is also used as a stabilizer in water-based coating, ink, and adhesive formulations. Scogin® IN2420 is a sustainable alternative to the traditionally used fossil fuel–based additives and binders used in these applications. In water, Scogin® IN2420 added at 1 wt% creates a solution with a viscosity of 15–25 mPa·s. If a medium-strength gel is needed, calcium can also be added to the solution for gelation to occur.

Some other applications that Scogin® IN2420 can be used in are active-ingredient encapsulation, paper and board manufacturing, and water treatment.

Due to its excellent film-forming properties, Scogin® IN2420 is ideal for paper and board sizing as well as manufacturing paper coatings. This film-forming property also makes Scogin® IN2420 useful in bioplastics research and fabrication. When used for water treatment, Scogin® IN2420 functions as an effective flocculant, especially when utilized as a co-flocculant with metal-based flocculants. Scogin® IN2420 alginate has a long, linear molecular structure that effectively entraps and encapsulates active ingredients that can be found in agricultural and industrial formulations.
