Test material

Constituent 1
Reference substance name:
Sulfonic acids, C16-alkane hydroxy and C16-alkene, sodium salts
EC Number:
297-664-9
EC Name:
Sulfonic acids, C16-alkane hydroxy and C16-alkene, sodium salts
Cas Number:
93686-15-8
IUPAC Name:
Sulfonic acid, C16-alkane hydroxy and C16-alkene, sodium salts
Test material form:
solid
Remarks:
This solid sample was obtained from the original liquid form by removing water.
Details on test material:
CAS number: 93686-15-8
Specific details on test material used for the study:
-Storage conditions
The test sample was sealed with nitrogen gas and stored with silica gel in a dark storage place at room temperature.

-Test item identification and stability under storage conditions
The infrared (IR) spectrum of the test item measured at this test facility was confirmed to be identical to that provided by the sponsor.
In addition, the IR spectrum of the test item after the completion of the experiment was the same as that before the start of the experiment, and it indicated that the test item was stable under the storage conditions.
