   WGK 1 (slightly hazardous to water)

2. C8-C14-Alkyloxiranes

   WGK 2 (obviously hazardous to water)

3. N-1,3-Dimethylbutyl-N'-phenyl-p-phenylenediamine

   WGK 3 (highly hazardous to water)

4. 4-Cyclohexan-1-ol, dodecyl-, branched

   WGK 1 (slightly hazardous to water)

5. 5-[(2-Hydroxyethyl)amino]-o-cresol

   WGK 2 (obviously hazardous to water)
