Scogin® MV is a sodium alginate polymer naturally derived from seaweed. It is typically used as a thickener for aqueous solutions used in industrial applications.
Scogin® MV is a sustainable, biodegradable sodium alginate–based polymer that is derived from brown seaweed. Since it is naturally derived, Scogin® MV is an excellent replacement for fossil fuel–based additives and polymers that are used in several different industrial applications.
Scogin® MV produces a solution with a viscosity of 350–500 mPa·s when added into water at 1 wt%. If gels are needed to be produced, Scogin® MV can also be treated with calcium in order to form a medium-strength gel with a wide range of temperature stability. Scogin® MV is also film forming, offering benefits in applications such as coating and paper sizing. Additionaly, Scogin® MV exhibits encapsulating characteristics that make it useful in controlled-release applications for oils, particles, and liquids.
Scogin® alginates, including Scogin® MV, are also often used as thickeners, gelling agents, and stabilizing agents in adhesive, coating, and ink formulations. Within the textile industry, for example, Scogin® MV is used as a thickener in screen printing inks. It is inert to dyes and fibers and can be washed off easily. Alginates like Scogin® MV are also ideal raw materials for creating bioplastics.
