EWG Risk Score:
What is it?
1,2-Hexylene glycol is a chemical relative to the more-known propylene glycol. It's a clear viscous liquid used as a humectant, filler, thickener, and conditioning agent.
What are its risks?
- 1,2-Hexylene glycol is a penetration enhancer, meaning that it has the ability to cross the skin's barrier and also bring other chemicals in to the body. (Source)
- While it's considered to have a low-toxicity (ie it doesn't make you sick or immediately kill you upon ingestion) it is broken down in the body through oxidation, a process that releases free radicals. (Source)
- 1,2-Hexylene glycol can be a skin irritant. (Source)
While 1,2-Hexylene glycol isn't acutely toxic, it certainly isn't a beneficial ingredient that would nourish or benefit the body in any way, and only creates free radical damage as its absorbed in the body and broken down.
