Odorless light petroleum hydrocarbons may be safely used, as a component of nonfood articles intended for use in contact with food, in accordance with the following prescribed conditions:
(a) The additive is a mixture of liquid hydrocarbons derived from petroleum or synthesized from petroleum gases. The additive is chiefly paraffinic, isoparaffinic, or naphthenic in nature.
(b) The additive meets the following specifications:
(1) Odor is faint and not kerosenic.
(2) Initial boiling point is 300 °F minimum.
(3) Final boiling point is 650 °F maximum.
(4) Ultraviolet absorbance limits determined by method specified in § 178.3620(b)(1)(ii), as follows:
|Wavelength (Mµ)||Maximum absorbance per centimeter optical pathlength|
|280 to 289||4.0|
|290 to 299||3.3|
|300 to 329||2.3|
|330 to 360||.8|
(c) The additive is used as follows:
|As a plasticizer and absorber oil in the manufacture of polyolefin articles authorized for food contact use||In an amount not to exceed that required to produce intended effect, consistent with good manufacturing practice.|
|As a lubricant of fibers of textiles authorized for food contact use||At a use level not to exceed 0.15 percent by weight of finished fibers.|
|As a component of adhesives||Complying with § 175.105 of this chapter.|
|As a defoamer in the manufacture of paper and paperboard||Complying with § 176.210 of this chapter.|
|As a defoamer in coatings||Complying with § 176.200 of this chapter.|
