EC number: 276-911-4
CAS number: 72829-25-5
on experimental data FAT 40034 can be concluded to be not-biodegradable
and stable in the environment. The substance is designed to be used as a
dye for diverse textile fabrics. To ensure high performance and quality
of the treated fabric, these class of chemicals are designed to be not
biodegradable by microorganisms. The substance to be considered as not
biodegradable, hydrolytically stable in the pH range 4- 9, and not
sensitive to photodegradation. Hence its concluded that the substance
may be Persistent (P) or Very Persistent (vP).
40034 has a very low Partition coefficient value (-3.52). Due to very
low partition coefficient value conducting adsorption and desorption
test was considered scientifically not necessary. For the purpose
of risk assessment Koc was calculated using EPA tool KOCWIN and value of
log Koc -0.613 is considered for assessment. According to the screening
criteria for bioaccumulation (B for bioaccumulative, vB for very
bioaccumulative) given in the technical guidance provided by ECHA (ECHA
2008, Guidance on information requirements and chemical safety
assessment, Chapter R.11), a substance does not fulfil the B and the vB
criterion if its log Kow ≤ 4.5. The octanol-water partition coefficient
for the test item is log Pow = -3.52. This value is below the threshold
value of log Kow ≤ 4.5 . Hence, the substance is regarded as not
bioaccumulative neither fulfilling the B nor the vB criterion.
substance is not harmful or toxic upon oral ingestion as demonstrated by
acute oral tests. Also no acute systemic toxicity was observed when the
substance was applied to the skin or the mucosa of animals for tests on
skin and eye irritation and skin sensitisation.
is no evidence of chronic toxicity from the available oral dose toxicity
study is in rats. The acute oral LD50 of FAT 40147 in rats of both sexes
observed over a period of 14 days is greater than 2000 mg/kg bw. Based
on the results obtained in the 28-day repeated toxicity study (Read
across substance FAT 40850) by gavage, the NOAEL was determined to be
300 mg/kg bw .
substance is not classified as carcinogenic, mutagenic or reprotoxic
according to Regulation EC 1271/2008.
long-term studies for marine or freshwater organisms are available.
Therefore, based on current knowledge, the substance does not fulfill
the T criterion based on the PBT criteria according to Annex XIII of the
to the screening criteria provided by ECHA (ECHA 2008, Guidance on
information requirements and chemical safety assessment, Chapter R.11),
a substance has to be considered to fulfill the criteria for toxicity (T
for toxicity) if the EC50 or LC50 of a short-term aquatic toxicity test
is below 0.1 mg/L. The substance was tested for all three trophic levels
in the aquatic environment (fish, invertebrate and aquatic plants) using
acute test design and the lowest effect concentration is found to be LC/
EC50 >100 mg/L. Hence, it can be concluded that the substance does not
fulfil the criteria as a toxicant (T).
on the above discussion, it is clear that FAT 40034 (REACTIVE RED 024:1)
is neither PBT nor vPvB.
