Diisodecyl phthalate, DiDP

CAS Number
68515-49-1
Name
Diisodecyl phthalate, DiDP
SIN Groups
Phthalates
Reason for inclusion on the SIN List
This substance has endocrine disrupting properties. Exposure to diisodecyl phthalate in vivo has lead to disturbed reproduction and development in rodents, daphnia and fish. There is in vitro evidence of thyroidogenic activity and in vivo and in vitro evidence of estrogenicity.

(Bio)monitoring data
DiDP was found in elevated concentrations in urine of plastisol workers compared to a general German population. Metabolites of DiDP were detected in urine from mothers and their school-aged children, with higher  concentrations in the children. DiDP was detected in house dust in a Canadian study.(Kasper-Sonnenberg et al., 2012; Koch et al., 2012; Kubwabo et al., 2013)

Technical function of substances
Source: 
Used as plasticizer for polyvinyl chloride, and in non-PVC applications in other vinyl resins than PVC, e.g. acrylic plastic resins. DIDP is also applied in non-polymer applications, such as anti-corrosion and anti-fouling paints, sealing compounds, textile inks, etc. Source: HSDB
