Sourcing HEC Material

HI all, I am actually a stranger that has been trying to use some of your approaches to cleaning validations in food & beverage.

Can anyone tell me where I can find some HEC (hydroxyethyl cellulose)? At issue is that in one of the validation papers on this site it recommends 100,000 mPas (1.9% solutoin, 20C, 20 GH). maybe I am misunderstanding something but the best I can find is viscosity: 15,000-20,500 cP, 2 wt. % in H2O

Would that do the job? Thanks and love the site!
