I have researched chemical free polishes. I looked up butterlondon. They list many polishes that do not contain harmful “3”. If you have an Ulta store where you live, they carry butterlondon polish. China Glaze polish without these chemicals will have black label on bottom of bottle with white writing. OPI will have white label with green writing. Butterlondon $18 bottle. I opted for China Glaze. Just thought this might help.
