Name STEARALKONIUM DIMETHICONE PEG-8 PHTHALATE Description Stearalkonium Dimethicone PEG-8 Phthalate is a salt of stearyl dimethyl benzylamine and Dimethicone PEG-8 Phthalate; Siloxanes and silicones, di-Me, ethers with ethylene glycol, propylene glycol copolymer mono(hydrogen phthalate), N,N-dimethyl-N-octadecylbenzenemethanaminium salts Benefits HAIR CONDITIONING 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.
• Quaternary Ammonium Compound This chemical is also in a class of chemicals called quaternary ammonium compounds, or quats as they are called for short. Quats have been found in some studies to be toxic to mitochondria in our body's cells. • Possible Endocrine Disruptor Quats and PEGs have also been found to disrupt hormones, especially estrogen. • Contamination Concerns There is some data to suggest that quaternary ammonium compounds can release carcinogenic nitrosamines under certain conditions.
