Additional information

CAS No. 147-14-8: A GLP conform reproduction/developmental toxicity screening study was conducted by gavage with the test material according to OECD guideline 421 (JETOC 1995). Groups of 12 Sprague-Dawley per sex per dose were daily exposed by gavage to 0, 40, 200, 1000 mg/kg bw/day of the test substance. The administration period for males was from 14 days before mating, during the mating period and copulation, until 46 days. The administration period for females was from 14 days before mating to day 3 of lactation. Males were killed on days 28 and 47, females on day 28 and on day 4 of lactation. Maternal examinations included cage side observations (at least once every day visual inspection, observation of appearance and palpation), detailled clinical observations (reproductive capacity, examination of the oestrous cycle, the recording of occurrence of copulation and gestation, fertility, implantation, delivery and nursing indices, maternal behaviour, birth rate, pregnancy period), examination of body weight and of feed intake. Post-mortem examinations were conducted: Organs were removed, reproductive organs were weighed. Ovaries, uterus, harderian gland, eyeball, mammary gland, and spleen were histopathologically examined. The ovaries and uterine content were examined after termination. The examinations included gravid uterus weight, number of corpora lutea and the number of implantations. Fetal examinations were also conducted, details are listed below.A blue coloration of faeces was noted in all animals of the groups receiving 40 mg/kg bw or more; moreover blue-green or grayish blue discolorations of the contents of the stomach and intestines were noted in a few animals of the 200 mg/kg group and in almost all animals of both sexes in the 1000 mg/kg group. These changes were due to the colour of the test substance. No changes were observed in terms of mortality, body weight, food consumption, organ weight and histopathological examination. No effects were noted on the following endpoints: Reproductive ability of either sex (assessment of this endpoint included the examination of the oestrous cycle, the recording of occurrence of copulation and gestation, the calculation of copulation, fertility, implantation, delivery and nursing indices, the weight of testes and epididymis as well as histopathological examination of the reproductive organs), delivery, maternal behavior, viability, clinical signs and body weight changes. No statistically significant differences were observed in rate of live/dead pups born.

CAS No. 1328 -53 -6: Additionally, repeated dose toxicity studies with polychloro copper phthalocyanine and copper phthalocyanine (for study details see chapter 7.5) reported no changes in rats' testes (90-day and 28-day study) and ovaries (28-day study) as confirmed by histopathological investigations.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008

The available screening study is reliable and suitable for classification purposes under Regulation 1272/2008. As a result, the substance is not considered to be classified for fertility or developmental toxicity under Regulation (EC) No. 1272/2008, as amended for the thirteenth time in Regulation (EC) No. 2018/1480.
