# §177.2410. Phenolic resins in molded articles.


Phenolic resins identified in this section may be safely used as the food-contact surface of molded articles intended for repeated use in contact with nonacid food (pH above 5.0), in accordance with the following prescribed conditions:

- (a) For the purpose of this section, the phenolic resins are those produced when one or more of the phenols listed in [paragraph (a)(1)](#a-1) of this section are made to react with one or more of the aldehydes listed in [paragraph (a)(2)](#a-2) of this section, with or without aniline and/or anhydro-formaldehyde aniline (hexahydro-1, 3,5-triphenyl-s-triazine):
  - (1) **Phenols—**
  - (2) **Aldehydes—**
- (b) Optional adjuvant substances employed in the production of the phenolic resins or added thereto to impart desired technical or physical properties include the following:
- (c) The finished food-contact article, when extracted with distilled water at reflux temperature for 2 hours, using a volume-to-surface ratio of 2 milliliters of distilled water per square inch of surface tested, shall meet the following extractives limitations:
  - (1) Total extractives not to exceed 0.15 milligram per square inch of food-contact surface.
  - (2) Extracted phenol not to exceed 0.005 milligram per square inch of food-contact surface.
  - (3) No extracted aniline when tested by a spectrophotometric method sensitive to 0.006 milligram of aniline per-square inch of food-contact surface.
- (d) In accordance with good manufacturing practice, finished molded articles containing the phenolic resins shall be thoroughly cleansed prior to their first use in contact with food.
