Similar term(s): Di-n-butyl phthalate, DNBP, Butyl phthalate, n-Butyl phthalate.
DBP, also known as DNBP, is a phthalate with the same core structure as
DINP but with two shorter side chains
attached, each having four carbon atoms.
In the 1990s, over 75% of DBP was used as plasticiser in plastics such as
PVC, 14% in adhesives, 7% in printing inks
and 3% in other miscellaneous uses, including sealants and grouting agents used
in construction as well as consumer products. For instance, it was used as an
additive to perfumes, deodorants, hair sprays, nail polish, printer inks, and
At present, DBP is banned in all toys and childcare articles (see
Directive 2005/84/EC) as
well as in cosmetics, including nail polish as it is considered to be
carcinogenic, mutagenic or toxic to reproduction (CMR-substance) (see
European Cosmetics Directive).
