No toxicity was observed up to the limit of the water solubility of the test substance under conditions tested.

- Validity criteria fulfilled:
- yes
- Conclusions:
- The substance is not harmful to fish within its limit of solubility in water.
- Endpoint:
- short-term toxicity to fish
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Guideline study with acceptable restrictions (no data on number of fish, only two concentrations tested, no analytics)
- Justification for type of information:
- Toxicity data from a structurally related source substance (Glycerides, C14-18 and C16-18 unsatd. mono- and di-, CAS 67701-33-1) are used as read-across in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5. Both are UVCB substances, formed from the esterification of fatty acids and glycerol, having a high content of C18 fatty acids and to a certain extent C14 and C16 fatty acids. Both are composed of mono- to tri esters (Target substance: monoester: 61.9%, diester<: 29.7%, triester: 3.2%; Source substance: monoester: 30 -65%, diester: 20 -50%, triester: 4 -15%). Furthermore, their water solubilities are comparable (< 1 mg/L). Therefore, these two substances are expected to show similar environmental behaviour and comparable degrees of toxicity to aquatic organisms. Based on the above information, the use of data from Glycerides, C14-18 and C16-18 unsatd. mono-, di- and tri- as read-across for Glycerides, C14-18 mono- and di- is considered justified.

Key value for chemical safety assessment
Additional information
No study is available investigating the short-term toxicity of Glyceride, rape oil mono-, di- and tri-, hydrogenated (CAS 91744-94-4) to fish. Therefore, toxicity data from a structurally related source substance (Glycerides, C14-18 and C16-18 unsatd. mono- and di-, CAS 67701-33-1) are used as read-across in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5. Both are UVCB substances, formed from the esterification of fatty acids and glycerol, having a high content of C18 fatty acids and to a certain extent C14 and C16 fatty acids. Both are composed of mono- to tri esters (Target substance: monoester: 61.9%, diester<: 29.7%, triester: 3.2%; Source substance: monoester: 30 -65%, diester: 20 -50%, triester: 4 -15%). Furthermore, their water solubilities are comparable (< 1 mg/L). Therefore, these two substances are expected to show similar environmental behaviour and comparable degrees of toxicity to aquatic organisms. Based on the above information, the use of data from Glycerides, C14-18 and C16-18 unsatd. mono-, di- and tri- as read-across for Glycerides, C14-18 mono- and di- is considered justified.
Two studies evaluating the acute toxicity of Glycerides, C14-18 mono- and di- (CAS No. 67701-33-1) are available. The key study (Guhl, 1992) was conducted according to ISO 7346-1, under GLP conditions. Fish were exposed to two concentrations of test substance (3000 and 10000 mg/L) for 96 hours within a semi-static water regime. After the exposure period, no mortality was observed in any of the treatment groups, or in the control. Therefore, the LC50 (96 h) was determined to be > 10,000 mg/L (nominal concentration). The supporting study (Richterich and Mühlberg, 2001) was performed following ISO 7346-1 as well. Danio rerio was exposed to 100, 1000 and 10000 mg test substance/L within a semi-static water regime. After 96 hours, only one fish died at a concentration of 1000 mg/L and therefore, the LC50 (96 h) was determined to be > 10,000 mg/L. Based on the above information, the use of data from Glycerides, C14-18 and C16-18 unsatd. mono-, di- and tri- as read-across for Glycerides, C14-18 mono- and di- is considered justified.
The study with the source substance (Guhl, 1992) was conducted according to ISO 7346-1, under GLP conditions. Fish were exposed to two concentrations of test substance (3000 and 10000 mg/L) for 96 hours within a semi-static water regime. After the exposure period, no mortality was observed in any of the treatment groups, or in the control. Therefore, the LC50 (96 h) was determined to be > 10,000 mg/L (nominal concentration) indicating that the substance is not harmful to fish within its limit of solubility in water. Based on the suitability of the read across approach this is also considered to be true for the target substance.
