Natrosol™ Plus and PolySurf™ cetyl modified hydroxyethylcellulose
Odor: odorless
Use: Hydrophobically modified hydroxyethylcellulose (HMHEC) is made in a two-step reaction. The first is the standard reaction of alkali-cellulose with ethylene oxide to produce HEC. The second step is a cetyl substitution, which provides the hydrophobic end groups. The resultant nonionic polymer is purified and dried. HMHEC for personal care and cosmetic applications is sold as Natrosol Plus 330 CS and PolySurf™ 67 CS. HMHEC polymers are unique in that they function as associative thickeners, meaning they not only thicken aqueous systems via chain entanglement and conventional hydrogen bonding, but also via hydrophobe interactions. In solution, hydrophobe groups seek out other hydrophobes, including oils and pigments, forming weak interactions and effectively creating a three-dimensional polymer network.
