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 nonionic polymer is purified and dried. HMHEC polymers not only thicken aqueous systems via chain entanglement and conventional hydrogen bonding, but also via hydrophobe interactions creating in solution, a three-dimensional polymer network. Pseudoplastic shear thinning behavior, high salt tolerance and long-term stability over a very wide pH range (3.5-11). HMHEC also behaves as a polymeric co-emulsifier and can be used to stabilize O/W emulsions without the use of conventional high HLB, water-soluble surfactants, enabling a much milder formulation.
