We recommend avoiding

Description

Oxirane, 2-methyl-, polymer with oxirane, ether with 5-[2-[4-[bis(2-hydroxyethyl)amino]-2-methylphenyl]diazenyl]-3-methyl-2,4-thiophenedicarbonitrile (2:1)

Benefits

COLORANT, HAIR DYEING

Considerations

• Ethoxylated Chemical This is an ethoxylated chemical, meaning it’s been created with ethylene oxide, traces of which, along with its carcinogenic byproduct, 1,4-dioxane, can remain in the product. • Endocrine Disruption PEGs have been associated with reproductive toxicity and xenoestrogenic properties.

Summary

Contamination concerns (carcinogenic ethylene oxide and/or 1,4-dioxane), suspected endocrine disruption.
