Description

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 consistsof polyethylene glycols and glycerol ethoxylate. Kolliphor^® RH 40 is a white to yellowish paste at 20°C.

Widely used and approved solubilizer
Particularly suited for aqueous solutions of fat-soluble vitamins
Chemically stable and practically tasteless – perfect for oral applications
Suitable for SEDDS and SMDDS as It is less digestible in GIT conditions as compare to other unsaturated ethoxylated surfactants

Non-ionic oil-in-water solubilizer and emulsifying agent.

Derived from hydrogenated castor oil and ethylene oxide, Kolliphor^® RH40 is used as a non-ionic oil-in-water solubilizer and emulsifying agent. It is particularly suitable for fat-soluble vitamins and demonstrates exceptional chemical stability. This tried-and-trusted solubilizer scored highest on resistance to enzymatic digestion in a study of various surfactants, highlighting its potential to enhance patient safety. Kolliphor^® RH40 is widely used in self-emulsifying drug delivery systems (SEDDS) or microemulsifying systems (SMDDS) in combination with a co-solubilizer and/or co-solvent. What’s more, Kolliphor^® RH40 is almost tasteless – making it ideal for oral applications.
