Water/94.0% Thin Boiling Starch/6.0% The starch and water are charged into a three-neck flask and heated with good agitation to 210'F in 30 minutes. The cooking is continued for an additional 30 minutes. At the end of this time water loss is adjusted and the preparation cooled. (Salt may be added if desired, without affecting the properties of the "Arquads".) the concentrations of "Arquad "s shown on the following table are expressed as per cent active "Arquad" on the weight of dry starch. For example, a formula using 1.5% "Arquad" 12 would appear as follows Thin Boiling Starch/6.00 "Arquad" 12 (100% active)/0.09 Water/93.91
