Sec.  20.112  Special industrial solvents general-use formula.

    (a) A special industrial solvent is any article made with any other 
ingredients combined with the ingredients in the minimum ratios 
prescribed in this section. A special industrial solvent shall be made 
with S.D.A. Formula No. 1, 3A, or 3C containing, for every 100 parts (by 
volume) of alcohol:
    (1) No less than 1 part (by volume) of one or any combination of the 
following: methyl isobutyl ketone, methyl n-butyl ketone, nitropropane 
(mixed isomers), or ethylene glycol monoethyl ether, and
    (2) No less than 5 parts (by volume) of one or any combination of 
the following: ethyl acetate (equivalent to 85% ester content, as 
defined in Sec.  21.106 of this chapter), isopropyl alcohol, or methyl 
alcohol.
    (b) Special industrial solvents are intended for use as ingredients 
or solvents in manufacturing processes and shall not be distributed 
through retail channels for sale as consumer commodities for personal or 
household use. When a special industrial solvent is used in the 
manufacture of an article for sale, sufficient ingredients shall be 
added to definitely change the composition and character of the special 
industrial solvent. A special industrial solvent shall not be 
reprocessed into another solvent intended for sale if the other solvent 
would contain more than 50% alcohol by volume.
    (c) If this article contains more than 4% by weight of methyl 
alcohol, the label shall have a skull and crossed bones symbol and the 
following words: ``danger,'' ``poison,'' ``vapor harmful,'' ``May be 
fatal or cause blindness if swallowed,'' and ``Cannot be made 
nonpoisonous.''
