- Executive summary:
In an acute dermal toxicity study (comparable to OECD guideline 402), groups of 3 male and female New Zeeland White rabbits were dermally exposed to MDEA-Esterquat C16-18 and C18 unsatd. (40 % a.i) in oleum arachidis for 24 hours to10 x 15 cm of body surface area at doses of 2000 mg/kg bw. Animals then were observed for14 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.
MDEA-Esterquat C16-18 and C18 unsatd. is practically non – toxic in this study.
There were no treatment related clinical signs, necropsy findings or changes in body weight.
Slight (1) to moderate (2) erythema and mainly moderate (2) edema with partly decreased intensity were observed at the treatment sites from 24 hours up to the 72 hours after treatment and were fully reversible within 7 days. The mean score were 1.3 for erythema and 1.75 for edema (after 24 and 72 hours). The applied scores of 1 and 2 for erythema and edema were comparable to the scores of the Draize method.
Reference
Skin assessments made at 24 hrs, 3, 7 and 14 days revealed that 2 mg/kg MDEA-Esterquat produced moderate skin irritation. Slight (3/6 rabbits) to moderate (3/6 rabbits) erythema and moderate edema at the 24 hour reading; slight (5/6 rabbits) to moderate (1/6 rabbits) erythema and slight (3/6 rabbits) to moderate (3/6 rabbits) at day 3. These skin responses resolved at day 7. No atonia, desquamation, fissuring, eschar or exfloliation was observed in the animals in this study.

Additional information
Acute oral toxicity
In an acute oral toxicity study according to OECD guideline 423, adopted 17 December 2001 and EPA OPPTS 870.1100 (Acute Oral Toxicity) EPA 712-C-02-190, December 2002, 6 female, fasted, 8-12 weeks old Wistar strain rats were given a single oral dose of MDEA Esterquat C18 satd. in water (10% w/w) by gavage at the limit dose of 2000 mg/kg bw and observed for 14 days.
All animals survived until the end of the study period. No clinical signs were observed in any animal at any observation timepoint. The body weight of the animals was within the range commonly recorded for this strain and age. No test substance related macroscopic findings were recorded at necropsy. The oral LD50 for female rats was > 2000 mg/kg bw.
Also the source substance used for read-across for the endpoints irritation, sensitisation, mutagenicity and developmental toxicity, MDEA-Esterquat C16-18 and C18 unsatd., was of equally low oral toxicity as demonstrated by the following studies on rats and mice:
In an acute oral toxicity study comparable to OECD Guideline 401 (24. Feb. 1987, now deleted) rats were dosed once with 10 000 mg/kg bw MDEA-Esterquat C16-18 and C18 unsatd. and observed for 14 days. No mortality occurred in this limit test. There were no treatment related clinical signs, necropsy findings or changes in the body weight.
The second study with mice was performed as an Irwin dose-range finding study with oral application of 316, 1000, 3160 and 10 000 mg/kg bw of MDEA-Esterquat C16-18 and C18 unsatd. and with an observation period of 7 days. All mice dosed with 10 000 mg /kg bw showed slight apathy between 10 and 20 minutes after dosing. In addition, one animal in this group showed further indication of CNS depression when observed at 30 and 90 minutes after treatment. This animal appeared normal during the observations performed at 150 and 300 minutes; however it died overnight between day one and day two. No other treatment related clinical signs, were recorded in the remaining animals at any time during the study. Necropsy was not performed after study termination; changes in body weights were not recorded.
Acute dermal toxicity
Testing of acute dermal toxicity of MDEA Esterquat C18 satd. is scientifically not justified according to REACH Regulation Annex XI 1 as reliable and relevant in vivo data from a structurally related substance and a QSAR calculation with the target substance are used to fulfill this information requirement.
In an acute dermal toxicity study according to OECD Guideline 402 (24 April 2002) New Zealand White rabbits were dermally exposed to MDEA-Esterquat C16-18 and C18 unsatd. (40 % a.i.) in oleum arachidis. Treatment occurred on an area of 10 x 15 cm of body surface at doses of 2000 mg/kg bw for 24 hours. Animals were observed for 14 days afterwards.
No mortality occurred in this limit test. There were no treatment related clinical signs, necropsy findings or changes in body weight. Slight to moderate erythema and mainly moderate edema with partly decreasing intensity were observed at the treatment sites up to day 3 and were fully reversible within 7 days. MDEA-Esterquat C16-18 and C18 unsatd. is practically non-toxic based on the dermal LD50 of > 2000 mg/kg bw determined in this study.
Justification for read-across
For details on substance identity, toxicokinetics and detailed toxicological profiles, please refer also to the general justification for read-across given in chapter 5 of the CSR and attached as pdf document to section 7 of the IUCLID file.
a. Structural similarity and functional groups
The target substance, MDEA Esterquat C18 satd., consists of an amine backbone (MDEA = Methyldiethanol amine) esterified with the long chain fatty acid stearic acid (C18 satd.; IV (iodine value) < 1). The main reaction product is the dialkylester compound, next to that small amounts of the monoalkylester may be formed. The amine function is quaternised with two methyl groups. The counter ion is Chloride.
The source substance, MDEA Esterquat C16-18 and C18 unsatd., consists of the same amine backbone (MDEA = Methyldiethanol amine) but esterified with a mixture of the long chain fatty acids C16, C18 and C18 unsaturated (IV < 25). The main reaction product is the dialkylester compound, next to that small amounts of the monoalkylester may be formed. The amine function is quaternised with two methyl groups. The counter ion is Chloride.
The source and the target substance share structural similarities with common functional groups (quaternary amines, esters, and fatty acid chains with comparable length and degree of saturation).
b. Common breakdown products
The metabolism expected to occur is hydrolysis of the ester-bond by esterases. However, the rate of hydrolysis is assumed to be low. The fraction of metabolised molecules would result in free fatty acids and Dimethyl-DEA (DEA = Diethanolamine). The carboxylic acids are further degraded by the mitochondrial beta-oxidation process (for details see common text books on biochemistry). The fatty acids enter normal metabolic pathways and are therefore indistinguishable from fatty acids from other sources including diet. The quaternary ammonium ions are not expected to be further metabolised, but excreted unchanged via the urine.
c. Differences
The differences in fatty acid chain length (higher percentage of C16 in the source substance MDEA Esterquat C16 -18 and C18 unsatd.) and degree of saturation (higher degree of unsaturation of the C18 fatty acid chains in the source substance substance MDEA Esterquat C16-18 and C18 unsatd.) could be relevant for local toxicity (skin and eye irritation) but arebut are not considered to be of relevance for acute toxicity.

Conclusion acute dermal toxicity
The acute oral toxicity for MDEA-Esterquat C16-18 and C18 unsatd. and MDEA Esterquat C18 satd. is equally low for both of them with an LD50 >> 2000 mg/kg bw. Low dermal toxicity with an LD50 >> 2000 mg/kg bw is shown in vivo for the source substance, MDEA-Esterquat C16-18 and C18 unsatd.. The oral bioavailability is assumed to be around 50 times higher than dermal bioavailability (see table), therefore acute toxicity after dermal administration is not to be expected and testing in animals is not warranted.
Further support is given by retrospective data analyses undertaken by Creton et al. (2010) and Seidle et al. (2010) to ascertain the value of regulatory requirements prescribing multiroute testing for acute systemic toxicity. These analyses have examined the concordance among regulatory classifications for acute oral, dermal, and/ or inhalation toxicity for ~500 agrochemical and biocidal active substances and nearly 2000 industrial chemicals. The findings from these two independent reviews have revealed that acute dermal studies of pure substances do not add value above and beyond oral data for hazard classification of pesticides, biocides, or chemicals.
Testing of acute dermal toxicity of MDEA Esterquat C18 satd. is therefore scientifically not justified according to REACH Regulation Annex XI 1 as reliable and relevant data from a structurally related substance is used to fulfil this information requirement.
Acute inhalation toxicity
Inhalation is not a relevant route of exposure to MDEA Esterquat C18 satd.. This applies to both workers and the general population and is due to the physicochemical properties of the substance and the nature of the products where it is used.
MDEA Esterquat C18 satd. is a waxy solid. Generation of inhalable particles such as dust or aerosols is therefore not to be expected. Vaporization needs not to be considered due to the substance’s very low vapour pressure of < 10-7 kPa. The substance is not manufactured into any REACH relevant spray or aerosol product applications. Therefore formulation of the substance into the commercial products where it is present does not result in any likely possibility of airborne exposure. For further information please refer to the exposure scenarios in chapter 9 and 10.
Given that acute toxicity is unlikely to occur based on low acute toxicity via the oral and dermal route, as well as on low exposure levels, testing by the inhalation route is scientifically not necessary according to REACH Regulation Annex XI 1 and 3.
Based on the available information, the acute toxicity of MDEA Esterquat C18 satd. is low for all three routes of administration. There are no data gaps in acute toxicity. Even though there is no information on acute toxicity in humans, there is no reason to believe that the low acute toxicity observed in experimental animals would not be relevant for human health.
