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:
| Use
| Limitations
|
|---|
| 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. |
