Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

38.03 mg/L

Applicant's summary and conclusion

The test item is considered as not surface active in a concentration of 38.03mg/L
Executive summary:

At the plateau (second measurement series), the values of the single determinations show no significant difference (less than 5 %, 1.15%) between mean values of the two-measurement series, second and third measurement series).

All measured values are higher than 60 mN/m, the measured values at the plateau lay above the threshold for surface tension which is stated in the guidelines.

The surface tension of the negative control was determined with a difference of 0.44 % from the stated literature value.


Therefore, the result of the test is considered valid and the test item Commercial name: CosmeGreen ES1822+Substance name: Reaction mass between glycine betaine,

ethanesulphonic acid, octadecan-1-ol, docosan-1-ol and eicosan-1-ol is classified as


“not surface active” in a concentration of 38.03 mg/L


(in a solution of 90% saturated solution obtained from an aqueous solution prepared by shaking 1.00g/L of test item for 24 hours and 5 minutes).
