Description
A strong solvent with a minty odor that can soften dried Linseed oil films (Mayer 1969). Diacetone alcohol is used as a solvent for Cellulose nitrate, Cellulose acetate, oils, resin, waxes, fats, tars, lacquers, dyes, and oil stains. It is also used for preserving wood, leather, and animal tissue and for cleaning metals and textiles. Toch (1931) mentions diacetone alcohol for coalescing crackle on old varnish films.
