PEG-7 Propylheptyl Ether
What is PEG-7 Propylheptyl Ether?
PEG-7 Propylheptyl Ether is a synthetic compound often used as an emollient or surfactant in personal care products. It is derived from ethylene oxide and propylheptyl alcohol, making it a member of the polyethylene glycol (PEG) family.
This ingredient is commonly used in hair care products for its ability to help spread and evenly distribute other ingredients on hair strands or skin. Health concerns are generally centered around potential contamination with ethylene oxide and 1,4-dioxane, which are possible carcinogens. However, there is limited direct evidence of harm from PEG-7 Propylheptyl Ether itself.
When you see it on a label, it is worth noting that the overall safety often depends on the manufacturing process and purity standards upheld by the manufacturer.
Commonly found in: Shampoos, Conditioners, Hair Styling Products, Skin Creams, Lotions
What to watch
- Possible contamination with ethylene oxide, a potential carcinogen.
- Possible contamination with 1,4-dioxane, a potential carcinogen.
