Additional information
There are no data available on the toxicity to reproduction (fertility) of Reaction products of D-Glucose, n-Butanol and C10-12 (even numbered) alcohols. In order to fulfil the standard information requirements set out in Annex IX, 8.7, in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006, read-across from structurally related substances is conducted.
A detailed justification for the grouping of chemicals and read-across is provided in the technical dossier (see IUCLID Sections 7.1 and 13).
Data on reprotoxicity is available from D-Glucopyranose, oligomeric, C10-16-alkyl glycosides, which is used for category approach.
In a reproductive/developmental toxicity screening assay according to OECD 421, the test substance was applied to 40 males and 40 females Sprague-Dawley rats prior to mating, throughout the gestation and lactation period until post partum Day 4 (RTC Ltd., 2007). Treatment by gavage with 0, 100, 300 and 1000 mg/kg bw/day began 7 days after allocation for both males and females. Treatment commenced when males and females were approximately 12 weeks of age, 2 weeks before pairing and continuously thereafter, up to the day before sacrifice (study Day 53, Day 4 post partum). No effects on the fertility were observed up to the highest dose, thus a NOAEL of 1000 mg/kg bw/day was derived for the test substance.
The lack of major toxicity was further confirmed by a subchronic toxicity study in Sprague Dawley rats that did not show any substance-related systemic toxic effects in either gender up to the limit dose of 1000 mg/kg bw (Henkel, 1989).
From the studies presented, there is no indication for any impairment of reproduction, either with regard to the development of the progeny or to the effects on fertility both of the structural and functional level. Therefore, a hazard of reproductive toxicity for Reaction products of D-Glucose, n-Butanol and C10-12 (even numbered) alcohols is not expected to occur, either.
However, it must be noted that a reproduction/developmental screening study is not suitable to exclude for sure the presence of toxic effects to reproduction if the result is negative. Nevertheless, together with the results of the subchronic toxicity investigations (no effects on male or female reproductive organs), it can be concluded that alkyl polyglycosides are substances of no concern with regard to toxicity to reproduction.
Short description of key information:
NOAEL (OECD 421), rat, systemic and reproductive toxicity = 1000 mg/kg bw/day, based on read-across
Justification for selection of Effect on fertility via oral route:
Hazard assessment is conducted by means of read-across based on a category approach. The selected study is the most adequate and reliable study based on the identified similarities in structure and intrinsic properties between source and target substance and overall assessment of quality, duration and dose descriptor level (refer to the endpoint discussion for further details).
Justification for selection of Effect on fertility via inhalation route:
No study required since the substance has a low vapour pressure and is marketed in aqueous formulation; therefore, human exposure to vapours or dusts is not to be expected.
Justification for selection of Effect on fertility via dermal route:
No study required since data from structurally related substances according to Regulation (EC) No 1907/2006, Annex XI, article 1.5 demonstrate a lack of acute toxicity via the dermal route and negligible dermal absorption through human skin in vitro.
Effects on developmental toxicity
Description of key information

Additional information
There are no data available on the toxicity to reproduction (development) of Reaction products of D-Glucose, n-Butanol and C10-12 (even numbered) alcohols. In order to fulfil the standard information requirements set out in Annex IX, 8.7, in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006, read-across from structurally related substances is conducted.

Teratogenic effects potentially induced by D-Glucopyranose, oligomeric, C10-16-alkyl glycosides were investigated in an OECD 414 compliant developmental toxicity study (Henkel, 1997). In detail, the test substance was tested according to OECD guideline 414 and in compliance with GLP at dose levels of 0, 100, 300 and 1000 mg/kg bw/day in 96 female Sprague-Dawley rats. The test substance was administered orally by gavage once daily from day 6 to day 15 of gestation. Control animals received the vehicle alone (aqua dest.) for the entire test period. Clinical conditions and reactions to treatment were recorded at least once daily. Body weights were reported on Days 0, 6, 16 and 20 of gestation. All surviving females were sacrificed on Day 20 of gestation and the foetuses were removed by caesarean section. At necropsy, the females were examined macroscopically and live foetuses were weighed, sexed, and examined for visceral and skeletal abnormalities. Gross macroscopic examinations included all maternal organs with emphasis on the uterus, uterine contents, position of foetuses in the uterus and number of corpora lutea. Number and distribution of intrauterine implantations were classified as live or dead foetuses, late intrauterine deaths (resorptions), early intrauterine deaths (resorption sites). The foetuses were removed from the uterus, were sexed, weighed individually and examined for gross external abnormalities and placentae were weighed separately. The brains and viscera of half of the foetuses of each litter were examined as well as skeletal abnormalities in the other half of the litter. The dams tolerated the applied dose levels of up to 1000 mg/kg bw/day without any signs of clinical toxicity. Skeletal and visceral investigations did not detect any treatment-related malformations. For the embryo/fetotoxicity, the teratogenicity and the maternal toxicity a NOAEL of 1000 mg/kg bw/day was deduced.
Based on the results of this study, there is no toxicity expected to occur for the structurally related Reaction products of D-Glucose, n-Butanol and C10-12 (even numbered) alcohols.

Hazard assessment is conducted by means of read-across based on a category approach.

Justification for classification or non-classification
The available data on reproductive and developmental toxicity of a structurally related substance to Reaction products of D-Glucose, n-Butanol and C10-12 (even numbered) alcohols according to the criteria laid down in regulation (EC) No 1907/2006, Annex XI, 1.5 do not meet the criteria for classification according to Regulation (EC) No 1272/2008 or Directive 67/548/EEC; therefore, Reaction products of D-Glucose, n-Butanol and C10-12 (even numbered) alcohols is not expected to meet the classification criteria, either, and the data is thus conclusive but not sufficient for classification.
