Propylene glycol is a small organic alcohol commonly used as a skin conditioning agent. Propylene glycol vs dipropylene glycol. Since propylene and butylene glycol are penetration enhancers that can help other ingredients enter your skin, many toxic ingredient lists say that theyll increase penetration of other toxic ingredients into the bloodstream. Could this also be the other way around, that there is a allergic reaction or a sensitivity to butylene glycol but not to propylene? 50% propylene glycol has a freezing pointof -31F, where 50% ethylene glycol freezes at -36F.

Thank you for this article, Ill just link to you int the future now. Confusingly, the names propylene glycol and butylene glycol can refer to several slightly different substances, since there are a few choices of carbon atoms for the OH groups to be attached to. Disclaimer, National Library of Medicine One report even shows that exposure to PG can cause skin, liver, and kidney damage. Propylene glycol solutions havehigher viscosity and higher freezing pointthan ethylene glycol at the same percentage, causing it to be less thermally efficient than ethylene glycol, especially at lower temperatures. Propylene glycol is a small, synthetic alcohol (chemical formula CH3-CHOH-CH2OH) that has the potential to cause allergic contact dermatitis in some individuals.
