The Washington Department of Ecology (DoE) has included 20 more chemicals and removed three others on the list of chemicals or substances that should be reported as required by the Children's Safe Products Reporting Rule.

The decision was announced on September 29 and it has considerably increased the previous list of Chemicals of High Concern for Children (CHCC).  Prior to the amendment, there were 66 items listed. Utilization of any of the chemicals or materials of high concern in manufacturing personal care, toys, clothing and other products for children should be reported.

The agency decided that these three chemicals that were taken out of the list do not meet the statutory criteria. Molybdenum & molybdenum components, octamethylcyclotetrasiloxane (D4) and phthalic anhydride.   

The chemicals added are the following:

  • Thirteen (13) kinds of flame retardants, including organohalogens.  The US Consumer Product Safety Commission (CPSC) has warned producers, consumers, and retailers not to use, make or sell products containing organohalogens.  
  • Four (4) phthalate chemicals. Studies done in animals and humans have associated phthalates with a number of health issues including those related to fertility and hormone disruption.  
  • Perfluorooctanoic acid (PFOA) or C8 which is used in products that resist water, heat, grease as well as stain. Studies show that PFOAs can cause cancer and other health issues. Substances that break down into PFOA are also included.  
  • Bisphenol F (BPF) and bisphenol S (BPS) are used as alternatives to for bisphenol A (BPA) which Washington state banned in 2010 for being an endocrine-disrupting material. The issue with BSF and BPS is that they may have some BPA-like behavior because they have similar chemical structures. 

Latest Addition to the CHCC List:

  • diisobutyl phthalate (DIBP);
  • dicyclohexyl phthalate (DCHP);
  • triphenyl phosphate (TPP); tris (2,3-dibromopropyl) phosphate (TDBPP );
  • di(2-methoxyethyl) phthalate (DMEP);
  • tri-n-butyl phosphate (TNBP);
  • bisphenol S (BPS);
  • perfluorooctanoic acid (PFOA);
  • dipentyl phthalate (DPP);
  • 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (TBB)
  • decabromodiphenyl ethane (DBDPE);
  • bis (2-ethylhexyl) 2,3,4,5-tetra bromophthalate (TPBH);
  • tricresyl phosphate (TCP);
  • tris (2chloroisopropyl) phosphate (TCPP);
  • ethylhexyl diphenyl phosphate (EHDPP);
  • isopropylated triphenyl phosphate (IPTPP);
  • bisphenol F (BPF) 
  • nonylphenol 4-nonylphenol (branched);
  • bis(chloromethyl)propane-1,3-diyl tetrakis-(2-chloroethyl) bis(phosphate) and
  • short-chain chlorinated paraffins

The state’s initial proposal was released in March this year, after the stakeholders’ meeting in August 2016. The attendees assessed and decided whether to add to remove from the list dozens of recommended substances or chemicals.


After considering the inputs and comments from 249 individuals and 13 organizations, the DoE decided on the following:


·         Add DMEP to the list

·         Reject the NGOs' recommendation to add the phthalates DIOP and DIPP due to lack of evidence to support their claim,

·         Amended the list of  PFOA chemicals to include the phrase "and related chemicals";

  •  Did not retain D4 on the list for issues on reproductive toxicity. The agency considered as insufficient the "mixed results" that was presented.  
  • Not to accept an NGO recommendation to include dechlorane plus due to limited and inconclusive toxicity data. 
  • Exclude from consideration the flame retardants butylated triphenyl phosphate and tris (4-tertbutyl phenyl) phosphate based on additional evidence of their toxicity.
