# §176.160. Chromium (Cr III) complex of N -ethyl- N -heptadecylfluoro-octane sulfonyl glycine.


The chromium (Cr III) complex of N-ethyl - N -heptadecylfluoro-octane sulfonyl glycine containing up to 20 percent by weight of the chromium (Cr III) complex of heptadecylfluoro-octane sulfonic acid may be safely used as a component of paper for packaging dry food when used in accordance with the following prescribed conditions.

- (a) The food additive is used as a component of paper in an amount not to exceed 0.5 percent by weight of the paper.
- (b)
  - (1) The food-contact surface of the paper is overcoated with a polymeric or resinous coating at least 1/3-mil in thickness, that meets the provision of [§ 176.170](/cfr/21/176.170.md); or
  - (2) The treated paper forms one or more plies of a paper in a multiwall bag and is separated from the food by at least one ply of packaging films or grease-resistant papers which serves as a functional barrier between the food additive and the food. Such packaging films or grease-resistant papers conform with appropriate food additive regulations.
- (c) The labeling of the food additive shall contain adequate directions for its use to insure compliance with the requirements of paragraphs [(a)](#a) and [(b)](#b) of this section.
