CAS number: 64742-48-9
A complex combination of hydrocarbons obtained by treating a petroleum fraction with hydrogen in the presence of a catalyst. It consists of hydrocarbons having carbon numbers predominantly in the range of C6 through C13 and boiling in the range of approximately 65°C to 230°C (149°F to 446°F).
Light catalytically cracked naphtha was administered once
daily to pregnant rats on gestation days 0-19 via dermal application at
doses of 30, 125, and 500 mg/kg to assess for developmental
toxicity. Maternal parameters (food consumption, body weight gain, serum
chemistry) were monitored throughout gestation and were not adversely
affected by treatment. No adverse effects were observed on eproductive
parameters (number of implants, resporptions, or viable fetuses) or on
fetal parameters (body weight or crown:rump length). No evidence of
teratogenicity was observed in fetues from pregant dams exposed to the
test material. Based on the study results, the maternal NOAEL and the
teratogenicity NOAEL were greater than 500mg/kg. These findings do not
warrant the classification of light catalytically cracked naphtha as a
developmental hazard under Regulation (EC) 1272/2008 on classification,
labeling, and packaging of substances and mixtures (CLP) or under the
Directive 67/518/EEC for dangerous substances and Directive 1999/45/EC
