There is indeed a relationship between the water retention and viscosity of HPMC (hydroxypropyl methylcellulose).
Generally speaking, the water retention of HPMC will increase as the viscosity increases, but when the viscosity of HPMC exceeds 100,000, the viscosity has little effect on the water retention.
HPMC (hydroxypropyl methylcellulose) is a water-soluble polymer that functions as a thickener, humectant and gelling agent.
