Applicationem

1. Maxime adhibetur ut polymerization inhibitor, UV inhibitor, tingunt medium et antioxidant BHA ad synthesim unguentorum edulorum et fucorum.
2. Inhibitoris polymerizationis, UV inhibitoris, inficiunt medium et antioxidant BHA (3-tert-butyl-4-hydroxyanisolum) pro synthesi ciborum oleis et uterentur.
3. Solvendo. Inhibitor vinyl monomer plasticus usus est; Uv inhibitor; Tinctura intermedia et antioxidant BHA (3-tert-butyl-4-hydroxyanisolum) in synthesi oleorum edulorum et fucorum adhibita. Maxima utilitas eius est quod monomerus additis MEHQ et aliis monomersis cum copolymerizing removeri non opus est, potest etiam copolymerizatio temaria directa adhiberi potest etiam ut antioxidant, antioxidant et sic porro.
