About
A higher-PEG oleate ester that functions as a versatile emulsifier — effective but raises more concerns about residual ethoxylation byproducts.
PEG-23 Oleate is a polyethylene glycol (23 EO) monoester of oleic acid. At this chain length (23 units), the PEG character dominates, giving the ingredient significant water solubility and a more hydrophilic profile. It functions as an emulsifying agent, surfactant, and skin-conditioning agent. The higher PEG chain length increases concern about potential contamination with 1,4-dioxane (a by product of ethoxylation classified as a probable human carcinogen) and residual ethylene oxide. However, with proper manufacturing (vacuum stripping), these contaminants are reduced to negligible levels. This ingredient is considered safe in practice when from reputable suppliers.
Skin benefits
- Effective emulsification at low concentrations
- Conditions skin
- Improves product texture
Known concerns
- Higher PEG chain length raises concerns about ethoxylation byproduct contamination (1,4-dioxane, ethylene oxide)
- May be a mild skin irritant in敏感皮 肤 at high concentrations
