Descripción

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.

Application

Polyethylene glycol 1500 can be used as:

A plasticizer in the synthesis of polylactic acid/talc composites to improve the crystallinity and mechanical properties of the material.
A non-ionic surfactant in the preparation of organoclays.
A reactant in the synthesis of quasi-prepolymers by reacting with a polymeric 4,4′-diphenylmethano diisocyanate (pMDI) via the pre-polymerization method.

PEG-1500 can also be used in the aqueous two-phase extraction system along with inorganic salts (sulfates, carbonates, and ammonium phosphates) for the separation and extraction of both organic (amino acids and vitamins) and inorganic substances (metal salts).
