Code of Federal Regulations Title 21. Food and Drugs § 21.173.60 Dimethylamine-epichlorohydrin copolymer

(1) The nitrogen content of the copolymer is 9.4 to 10.8 weight percent on a dry basis.

(2) A 50–percent–by–weight aqueous solution of the copolymer has a minimum viscosity of 175 centipoises at 25°C as determined by LVT-series Brookfield viscometer using a No. 2 spindle at 60 RPM (or by another equivalent method).

(3) The additive contains not more than 1,000 parts per million of 1,3–dichloro–2–propanol and not more than 10 parts per million epichlorohydrin. The epichlorohydrin and 1,3–dichloro–2–propanol content is determined by an analytical method entitled “The Determination of Epichlorohydrin and 1,3–Dichloro–2–Propanol in Dimethylamine–Epichlorohydrin Copolymer,” which is incorporated by reference.
