EC number: 250-705-4
CAS number: 31566-31-1
No toxic effects up to the limit of water solubility (< 1 mg/L) for Daphnia magna (OECD 211), read-across.
No studies investigating the long-term toxicity of Stearic acid,
monoester with glycerol (CAS No. 31566 -31 -1) to aquatic invertebrates
are available. Therefore, in accordance to Regulation (EC) No. 1907/2006
Annex XI, 1.5 Grouping of substances, a read-across to the structurally
related category members Glycerides, C14-18 and C16-18 unsatd. mono-,
di- and tri- (CAS No. 91052-28-7) was conducted. Further justification
is given within the endpoint summary 6.1 and within the category
justification section 13. In this case of read-across, the best suited
(highest degree of structural similarity, nearest physico-chemical
properties) read-across substance within this category was used.
The chronic toxicity of Glycerides,C14-18 and C16-18 unsaturated,
mono-, di- and tri- (CAS No. No. 91052-28-7) to aquatic invertebrates
has been evaluated by Salinas (2013). This test was conducted according
to OECD 211, under GLP conditions. Daphnia magna was exposed to the
substance at a single loading rate of 10 mg/L (limit test) for 21 days
within a semi-static water regime. At the end of the exposure period, no
effects on survival, reproduction or any other adverse effects were
reported. Therefore the NOELR was determined to be ≥ 10 mg/L (nominal,
Based on the results obtained for the structurally related
analogue (in accordance with Regulation (EC) No. 1907/2006, Annex XI,
1.5), Stearic acid, monoester with glycerol (CAS No. 31566 -31 -1) is
not expected to show long-term toxicity to aquatic invertebrates up to
the limit of its water solubility.
