Behind the Label: The Hidden Risks of PEG Compounds in Skincare
Posted By Marco Champion on
When you see PEG-7, PEG-40, or any other “PEG” on a skincare label, it may seem like just another technical ingredient. In reality, PEG stands for Polyethylene Glycol, a petroleum-derived compound used as a thickener, softener, and emulsifier. While it can make products feel luxurious, there’s a hidden cost to your skin and potentially your overall health.
What Are PEG Compounds?
PEGs are synthetic polymers made by combining ethylene glycol (a chemical also used in antifreeze) with varying amounts of ethylene oxide. In skincare, they’re prized for their ability to help ingredients blend together smoothly, improve texture, and enhance moisture absorption.
The Hidden Risks
The main problem with PEGs isn’t necessarily the compound itself, but the manufacturing process. PEGs can be contaminated with:
- 1,4-Dioxane — a probable human carcinogen.
- Ethylene Oxide — classified as a known human carcinogen.
These contaminants can remain in the final product if not properly removed, and because they’re not always listed on labels, consumers have no way of knowing they’re there.
Additionally, PEGs can compromise your skin barrier, making it easier for other harmful chemicals to penetrate the skin. This is particularly concerning for sensitive or damaged skin.
Environmental Concerns
Since PEGs are derived from petroleum, their production contributes to fossil fuel use and environmental pollution. Plus, they don’t break down easily, adding to long-term ecological impact.
Why We Avoid Them at Cure
At Cure, we believe skincare should heal, not harm. We never use PEG compounds because:
- They are synthetic and petroleum-derived.
- They carry contamination risks.
- They’re not aligned with our USDA Organic commitment.
Instead, we choose natural, plant-based emulsifiers and thickeners that are safe for both skin and planet.
Safer Alternatives
- Cetearyl Olivate & Sorbitan Olivate (from olive oil)
- Beeswax & Candelilla Wax
- Acacia Gum
- Xanthan Gum
Conclusion
While PEG compounds may seem harmless, their potential contaminants and petroleum origins make them an ingredient worth avoiding. Always read labels carefully and opt for brands that prioritize transparency and natural formulations.
