SYNTHALEN® MP is a USP grade synthetic polymer well known and widely used in the pharmaceutical industry as thickener and suspending agent thanks to its safety and versatility. Obtained through a proprietary manufacturing technique, it is practically solvent free. In fact, its residual solvent, i.e, methylene chloride, amount is much lower than the solvent limits guidance recommended by the International Conference on Harmonisation (ICH) that for a solvent of class 2 is 600 ppm. SYNTHALEN® MP dispersions are characterized by high viscosity in a large range of pH. Therefore it is very suitable for formulating gels as well as for stabilizing emulsions and dispersions for pharmaceutical applications. It can be used in topical preparations, oral products and retard systemic products (to release pharmaceutically active substances over an extended period of time when applied orally).
