CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN 
                          SERVICES (CONTINUED)
 
PART 178--INDIRECT FOOD ADDITIVES: ADJUVANTS, PRODUCTION AIDS, AND SANITIZERS--Table of Contents
 
            Subpart D--Certain Adjuvants and Production Aids
 
Sec. 178.3530  Isoparaffinic petroleum hydrocarbons, synthetic.

    Isoparaffinic petroleum hydrocarbons, synthetic, may be safely used 
in the production of nonfood articles intended for use in producing, 
manufacturing, packing, processing, preparing, treating, packaging, 
transporting, or holding food, subject to the provisions of this 
section.
    (a) The isoparaffinic petroleum hydrocarbons, produced by synthesis 
from petroleum gases consist of a mixture of liquid hydrocarbons meeting 
the following specifications:

Boiling point 63 deg. -260  deg.C, as determined by ASTM method D86-82, 
``Standard Method for Distillation of Petroleum Products,'' which is 
incorporated by reference. Copies may be obtained from the American 
Society for Testing Materials, 1916 Race St., Philadelphia, PA 19103, or 
may be examined at the Office of the Federal Register, 800 North Capitol 
Street, NW., suite 700, Washington, DC 20408.
Ultraviolet absorbance:
    260-319 millimicrons--1.5 maximum.
    320-329 millimicrons--0.08 maximum.
    330-350 millimicrons--0.05 maximum.
Nonvolatile residue 0.002 gram per 100 milliliters maximum.

    Synthetic isoparaffinic petroleum hydrocarbons containing 
antioxidants shall meet the specified ultraviolet absorbance limits 
after correction for any absorbance due to the antioxidants. The 
ultraviolet absorbance shall be determined by the procedure described 
for application to mineral oil under ``Specifications'' on page 66 of 
the ``Journal of the Association of Official Agricultural Chemists,'' 
Vol. 45 (February 1962), which is incorporated by reference, 
disregarding the last sentence of that procedure. For hydrocarbons 
boiling below 121  deg.C, the nonvolatile residue shall be determined by 
ASTM method D1353-78, ``Standard Test Method for Nonvolatile Matter in 
Volatile Solvents for Use in Paint, Varnish, Lacquer, and Related 
Products;'' for those boiling above 121  deg.C, ASTM procedure D381-80, 
``Standard Test Method for Existent Gum in Fuels by Jet Evaporation,'' 
which are incorporated by reference. Copies may be obtained from the 
American Society for Testing Materials, 1916 Race St., Philadelphia, PA 
19103, or may be examined at the Office of the Federal Register, 800 
North Capitol Street, NW., suite 700, Washington, DC 20408.

    (b) Isoparaffinic petroleum hydrocarbons may contain antioxidants 
authorized for use in food in an amount not to exceed that reasonably 
required to accomplish the intended technical effect.
    (c) Isoparaffinic petroleum hydrocarbons are used in the production 
of nonfood articles. The quantity used shall not exceed the amount 
reasonably required to accomplish the intended technical effect, and the 
residual remaining in the finished article shall be the minimum amount 
reasonably attainable.
