INTRODUCTION

Ethoxylated hydrogenated castor oil (PEG-40 hydrogenated castor oil) is a combination of synthetic polyethylene glycol (PEG) with natural castor oil. It is a multifunctional Oil-in- Water Emulsifier that is a very versatile and multifunctional non-ionic surfactant used as fragrance builder and fragrance solubilizer,emulsifier in cosmetics and as pharmaceutical aid.

MANUFACTURE

It is produced from castor oil by hydrogenating its double bonds and reacting with ethylene oxide, enhancing stability and emulsifying properties.
