pH drift can ruin your product dixring storage if it causes failure of t h e viscosity control agent. Methocel® (Dow methylcellulose) is being used as a viscosity control i n systems with a pH as low as 2 ajid a s high a s 12 with complete success. As a result of MethocePs stability, many latex and resin emulsion paints, pharmaceuticals a n d cosmetics now reach consumers without danger of damaging breakdown d u r i n g periods of storage.
