2.4,4'-Diaminodiphenylmethane C13H14N2, raw material for azo dyes; accelerator for synthetic rubber; curing agent for epoxy resin.
3.Dibutyl phthalate DBP, plastic, rubber and other commonly used plasticizers.
4. Butyl benzyl phthalate BBP, plastic, rubber and other commonly used plasticizers.
7. Cobalt dichloride CoCl2, used as a silica gel desiccant hygroscopic indicator, adding a certain amount of cobalt dichloride in silica gel, can show the degree of hygroscopicity of silica gel. It can also be used in the electroplating industry, as a colorant for glass and ceramics, as a paint drying agent, and as a cryptographic ink.SONY's SS-00259 8th edition is prepared to restrict the use of silica gel containing cobalt dichloride as well as humidity indicators containing cobalt dichloride.

11.Bis(2-ethylhexyl) phthalate DEHP, commonly used plasticizer for plastics and rubber.
12. Hexabromocyclododecane HBCDD, flame retardant.
13.Short-chain C10-13 chlorinated paraffin SCCP, flame retardant, plasticizer.
14. Tributyl tin oxide (TBTO), used as a fungicide, wood and textile protective agent, plastic heat stabilizer.
15.Lead hydrogen arsenate PbHAsO4, insecticide.
Cyclododecane C12H24 , used as nylon monomer, is the main raw material of nylon 12, nylon 612, nylon 1012. It is now no longer included in the substances of high concern.
