PEG-8 Laurate
What is PEG-8 Laurate?
PEG-8 Laurate is a synthetic compound typically formed by the reaction of lauric acid—found in coconut oil—and polyethylene glycol, a polymer of ethylene oxide. This ingredient is engineered in laboratories to create a multifunctional surfactant.
PEG-8 Laurate is often used in cosmetics and skincare products, like sunscreens, as an emulsifier and surfactant due to its ability to help water and oil mix. The health impact evidence on PEGs in cosmetics is mixed; they are generally regarded as safe in normal use, but there is some concern about potential impurities, like ethylene oxide and 1,4-dioxane, which can form during manufacturing.
When you see PEG-8 Laurate on a label, it indicates its primary function is to stabilize the product formulation, improving texture and spreadability.
Commonly found in: Sunscreen, Moisturizers, Conditioners, Facial Cleansers
What to watch
- There is a potential risk of impurities such as ethylene oxide and 1,4-dioxane being present due to manufacturing processes.
Benefits
- Effective in mixing oil and water, which enhances product texture and application.
The FDA considers polyethylene glycols (PEGs) generally safe for use in cosmetics, though they do not specifically regulate PEG-8 Laurate as an individual entity.
Research indicates that while PEG-8 Laurate itself is safe, impurities that may arise during its production could pose risks.
PEG-8 Laurate is synthetic and not derived from animal products, making it generally acceptable for vegan use.
