Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Studies on skin sensitisation of were available for the following Fatty Acid Glycerides category members (CAS No.):

91845-19-1, 620-67-7, 142-18-7, 555-43-1, 73398-61-5.

All available skin sensitisation studies showed that Fatty Acid Glycerides are not skin sensitising.

In silico/ in chemico/ in vitro tests covering skin sensitisation are being performed with the registered substance, octanoic acid, monoester with glycerol. When the new data is available section 7.4 Sensitisation and section 2.1 GHS will be updated accordingly.

RANGE FINDING TESTS:
3 preliminary tests were performed with 5 animals each:
For the intradermal induction a 1% concentration of test substance in vaseline induced sufficient skin irritation.
For the epidermal induction a 50% concentration of test substance in vaseline was determined as the minimal irritating concentration.
To be able to determine the maximum non-irritating concentration for challenge treatment, intracutaneous injections of 0.1 mL FCA bilaterally of the vertebral column were made. 2 weeks later 25% and 50% test substance concentrations were applied for 24 h under plaster-covering. A 25% concentration was found to be the maximum non-irritating concentrations.

Additional information:

Glyceride, C16-18- and C18-Hydroxymono- und Di- (CAS No. 91845-19-1) was tested for its skin sensitisation potential according to 79(831/EWG, Annex V, Part B), (Kästner, 1985). 20 Pirbright white guinea pigs were tested in a Guinea pig maximization test and compared with 20 negative control animals. Induction exposure was performed with the test substance at a concentration of 50 % in paraffin oil (1%) for intradermal application and in vaseline (50%) for epicutaneous application. Challenge treatment was performed by dermal application of the test substance at 25 % in vaseline. 24 and 48 hours after challenge exposure all skin examination scores were zero.

 

2,3-dihydroxypropyl laurate (CAS No. 142-18-7) was tested for its skin sensitisation potential in a Buehler test performed similar to OECD Guideline 406 (Sterner 1977). 10 Pirbright guinea pigs were tested and compared with 5 negative control animals. Three epicutaneous induction exposures were performed with the test substance at a concentration of 25 % in water. Epicutaneous challenge treatment was performed with the test substance at 25 % in water. 24 and 48 hours after challenge exposure all skin examination scores were zero.

 

Glycerol tristearate (CAS No. 555 -43 -1) was tested for its skin sensitisation potential according to OECD Guideline 406 (Krueger, 1998). The sensitivity of the guinea pig strain was confirmed by a Buehler test performed with alpha-hexylcinnamaldehyde. Twenty Dunkin-Hartley guinea pigs were tested in a Buehler test and compared with ten negative control animals. Three epicutaneous induction exposures were performed with the test substance at a concentration of 50 % in vaseline. Epicutaneous challenge treatment was performed with the test substance at 50 % in vaseline. 24 and 48 hours after challenge exposure all skin examination scores were zero.

 

Propane-1,2,3-triyl trisheptanoate (CAS No. 620-67-7) was tested for its skin sensitisation potential according to OECD Guideline 406 (Mürmann, 1993). Twenty Dunkin-Hartley guinea pigs were tested in a Buehler test and compared with ten negative control animals. Three epicutaneous induction exposures were performed with the unchanged test substance at a concentration of 100 %. Epicutaneous challenge treatment was performed with the test substance at 100 %. 24 and 48 hours after challenge exposure all skin examination scores were zero. .

Triglycerides, mixed decanoyl and octanoyl (CAS No. 73398-61-5) was tested for its skin sensitisation potential using a Buehler test method (Consultox, 1972). Six guinea pigs were tested in a Buehler test and compared with negative control animals. Ten epicutaneous induction exposures were performed with the test substance at a concentration of 4 % in ethanol. Epicutaneous challenge treatment was performed with the test substance at 4 % in ethanol. No range finding tests were reported. No skin reactions were observed in any of the six tested animals.
