ROKAmid MRZ4 is a non-ionic surfactant, part of the group of ethoxylated alkanolamides, under the INCI name PEG-4 Rapeseedamide. The product has the form of a liquid with a bright yellow to orange colour. ROKAmid MRZ4 has emulsifying properties and fulfils the role of a co-emulsifier supporting the emulsifier responsible for the creation of emulsions in O/W (oil in water) systems with waxes and mineral oils. At the same time, it is a stabilizer and enhances the quality of foam in mixtures with anionic surfactants. It is also used as a delicate detergent for skin and hair. Thanks to this, products containing ROKAmid MRZ4 exhibit reduced irritant potential. ROKAmid MRZ4 is an ingredient of detergents and body care products, such as shampoos, shower gels, hand soaps, shaving gels etc. It is also a good thickener. It acts as a foam enhancer and stabiliser, strong solubilizing and emulsifying agent and it exhibits effectiveness in products containing SLES as well as in non-SLES products. It is produced on the basis of renewable rapeseed oil and exhibits good biodegradability.
