PEG/PPG-18/18 Dimethicone
What is PEG/PPG-18/18 Dimethicone?
PEG/PPG-18/18 Dimethicone is a silicone-based compound known for its emulsifying properties, often used in personal care products. It is synthetically produced through the reaction of dimethicone with polyethylene glycol (PEG) and polypropylene glycol (PPG), resulting in a molecule that can interact with both water and oil.
This ingredient is primarily used in deodorants and other skincare products to help stabilize the formulation and improve texture by allowing water and oil components to mix smoothly. While some studies have raised concerns about PEG compounds due to potential impurities, PEG/PPG-18/18 Dimethicone is generally considered safe in the amounts used in cosmetics.
Consumers may want to note that this ingredient contributes to the silky, smooth feel of many products, and it is usually found in small concentrations.
Commonly found in: Deodorants, Lotions, Cleansers, Makeup, Haircare products
What to watch
- Some PEG compounds can be contaminated with impurities like 1,4-dioxane, a potential carcinogen.
Benefits
- Improves the texture and stability of cosmetic products by helping oils and water mix.
The FDA generally regards PEG compounds as safe for use in cosmetics, although they regulate impurities.
Research shows silicone compounds like dimethicone are typically safe on the skin, but concerns about impurities exist.
PEG/PPG-18/18 Dimethicone is synthetic and not animal-derived, making it suitable for vegan products.
Scout's take
Ethoxylated polymer carrying 1,4-dioxane contamination risk as a manufacturing byproduct.
