- REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
The hypothesis for this analogue approach is that target and source substances, being different compounds, have similar (eco) toxicological properties based on structural similarity with common functional groups; a quaternized ethanolamine moiety, one to three ester groups with a typical UVCB distribution with long-chain fatty acids of natural origin.
Furthermore identical precursors (triethanolamine, long-chain fatty acids, dimethyl sulphate) are used for manufacturing. Therefore common breakdown products via physical and biological processes, which result in structurally similar chemicals, are evident.

Additional information
No experimental data are available for the assessment of the acute toxicity of the target substance Fatty acids, C18 unsatd., mono and diester with triethanolamine , di-Me sulfate-quaternized. However, reliable relevant data are available for the closely related source substances oleic acid based TEA-Esterquat and partially unsaturated TEA-Esterquat.
Acute oral toxicity
In an acute oral toxicity study (according to EU Method B 1, fixed dose procedure), 5 male and 5 female Sprague-Dawley rats were given a single oral doses of 2000 mg/kg bw “oleic acid-based TEA-Esterquat” and observed for 14 days.
Oral LD50Males and Females > 2000 mg/kg bw (nominal)
No animal died. No clinical signs or effects on body weight were observed at 2000 mg/kg bw.
Gross pathological examinations at 14 days p.a. (terminal necropsy) revealed no test article-dependent findings. The only observation made was a dilatation of the right renal pelvis of one male.
In a further acute oral toxicity study (according to EU Method B.1), 5 Sprague-Dawley rats/sex/dose were given single oral doses of 2000 or 5000 mg/kg bw of partially unsaturated TEA-Esterquat (89.6 % a.i.) and observed for 14 days.
Oral LD50 Males and Females > 5000 mg/kg bw (nominal)
Oral LD50 Males and Females > 4480 mg/kg bw (based on a.i.)
No animal died. No clinical signs or effects on body weight were observed at 2000 mg/kg bw.
Hypokinesia was noted only in the treated males at the dose level of 5000 mg/kg bw, 30 minutes and one hour after treatment, then in all the animals after 2 and 4 hours. From day 2 to day 15, no clinical signs were observed at the dose level of 5000 mg/kg bw. These findings were accompanied by a slight slowed down of the body weight gain between day 1 and day 5 in the males at 5000 mg/kg bw. Normal weight gain was observed in the female 5000 mg/kg bw group. Gross pathological examinations at 14 days p.a. (terminal necropsy) revealed no test article-dependent findings.
Acute inhalation toxicity
According to REACH regulation, Annex XI, the conduct of an acute inhalation toxicity study is scientifically unjustified.
Testing on vertebrate animals for the purpose of REACH shall be undertaken only as a last resort. Information from acute oral and dermal toxicity studies are available, both LD50 values are > 2000 mg/kg and no signs of toxicity were observed up to 2000 mg/kg bw, thus the acute intrinsic toxicity is considered to be low.
Considering the physico-chemical properties of the substance exposure of humans via inhalation is not likely. The vapour pressure ofFatty acids, C18 unsatd., mono and diester with triethanolamine , di-Me sulfate-quaternizedis low (4.4E-4Pa) and the substance is marketed as aqueous suspension.
There is no consumer use of the substance.The generation of dusts and aerosols is prevented by appropriate RMMs, and the substance is not used in spray applications. Therefore no high peak exposure for the inhalation route is expected. As a precautionary measure a DNEL for short term exposure after inhalation will be set based on long-term inhalation DNEL.
In conclusion, according to REACH Regulation Annex XI 1 and 3 further testing on vertebrate animals for acute toxicity via inhalation route is scientifically not necessary, taken into account available information reflecting low acute intrinsic toxicity. As well there is no consumer use and exposure of workers via inhalation is not likely, taken into account physico-chemical properties and use description of the substance.
Acute dermal toxicity
In an acute dermal toxicity study according to OECD guideline 402, 1987 and EU method B.3, 1992, 5 male and 5 female young adult CD rats were dermally exposed to the partially unsaturated TEA-Esterquat suspended in water for 24 hours under an occlusive dressing to approx. 10 % of body surface area at doses of 2000 mg/kg bw. Animals then were observed for 14 days.
Dermal LD50 Males > 2000 mg/kg bw
Females > 2000 mg/kg bw
Combined > 2000 mg/kg bw
No mortality occurred in this limit test. No clinical signs were observed. No macroscopical changes were noted at gross pathological examinations at terminal necropsy. Normal weight gain was observed, except for one female rat. Its body weight gain appeared to be slightly reduced.
There are no data gaps for the endpoint acute toxicity. No human data are available. However, there is no reason to believe that these results from rat would not be applicable to humans.
Justification for read-across:
The read-across is built on the hypothesis that target and source substances, being different compounds, have similartoxicologicalproperties based on structural similaritywith common functional groups.
A detailed justification for read-across is attached to chapter 13 of the IUCLID file.
Justification for classification or non-classification
Based on the available data,Fatty acids, C18 unsatd., mono and diester with triethanolamine , di-Me sulfate-quaternizeddoes not need to be classified for acute toxicity according to regulation (EC) 1272/2008. Thus, no labelling is required.
