OptiSafe and OS2 Score Comparison for ROS/CL Antioxidant Titrations

Chemical Name GHS Condition OptiSafe Score, AVG ± STD OS2 Score, AVG ± STD
2-(2-Ethoxyethoxy) ethanol (111-90-0) NC ROS 21.7 ± 0.3 12.0 ± 0.3
Triethylene glycol (112-27-6) NC ROS 13.2 ± 3.5 5.1 ± 1.7
Ethylene glycol diethyl ether (629-14-1) NC ROS 25.4 ± 1.8 21.6 ± 2.5
Styrene (100-42-5) NC ROS 53.5 ± 10.1 3.5 ± 0.8
1,9-Decadiene (1647-16-1) NC CL 22.5 ± 3.6 11.4 ± 6.4
2-Ethoxyethyl methacrylate (2370-63-0) NC CL 97.1 ± 18.2 14.5 ± 2.7

OptiSafe (without antioxidants), OS2 = OptiSafe2 (OptiSafe with antioxidants added); GHS = Globally Harmonized System of classification and labelling of chemicals; NC = Not classified; ROS = Reactive oxygen species; CL = Crosslinker; AVG = Average; STD = Standard deviation.
