Kolliphor RH 40 is a nonionic solubilizer and emulsifying agent obtained by reacting 40 moles of ethylene oxide with 1 mole of hydrogenated castor oil. The main constituent of Kolliphor RH 40 is glycerol polyethylene glycol oxystearate, which, together with fatty acid glycerol polyglycol esters, forms the hydrophobic part of the product. The hydrophilic part consists of polyethylene glycols and glycerol ethoxylate. Kolliphor RH 40 is a white to yellowish paste at 20°C. Koliphor RH 40 is Widely used and approved solubilizer. It is Chemically stable and practically tasteless – perfect for oral applications. Kolluphor RH 40 is particularly suited for aqueous solutions of fat-soluble vitamins. Suitable for SEDDS and SMDDS as It is less digestible in GIT conditions as compare to other unsaturated ethoxylated surfactants
