PEG-8
What is PEG-8?
PEG-8 is a type of polyethylene glycol, a compound made by polymerizing ethylene glycol. It is characterized by a specific molecular weight, which makes it versatile for various applications.
In personal care products, PEG-8 is used primarily as a humectant, helping to maintain moisture in products like deodorants and skin creams. While PEG compounds are generally considered safe, there are concerns about contamination with potentially harmful impurities like ethylene oxide and 1,4-dioxane during the manufacturing process.
If you see PEG-8 on a label, it’s commonly used to improve the texture and moisture-retention of the product. Keep in mind potential concerns regarding impurities, though these are often more relevant to manufacturing quality control.
Commonly found in: Deodorants, Whitening Products, Moisturizers, Cleansers
What to watch
- Potential contamination with ethylene oxide, a known carcinogen.
- Possible presence of 1,4-dioxane, a compound considered a probable human carcinogen.
Benefits
- Helps to retain moisture in skin care and personal care products.
The FDA does not specifically regulate PEG-8 but monitors for impurities like 1,4-dioxane.
Research indicates PEGs themselves are low-risk, but contamination concerns vary by manufacturing quality.
PEG-8 is typically synthetic and not derived from animal sources, making it acceptable for vegans.
Scout's take
PEG compound — 1,4-dioxane contamination concern.
More from Scout's analyses
PEG-8 is a polyethylene glycol that acts as a humectant and thickener. It can be associated with skin irritation and is a synthetic compound, which raises concerns about its safety for prolonged oral contact.
