Science
Mechanism of Action
This ingredient reduces electrostatic charges, acting as an antistatic agent, especially beneficial for hair. In skincare, it primarily functions as a surfactant and emulsifier, decreasing surface tension to aid in the removal of impurities and stabilize oil-in-water emulsions. As a humectant, it attracts and retains moisture by forming hydrogen bonds with water molecules, thereby contributing to skin hydration and reducing water evaporation. Additionally, it has the capacity to enhance the penetration of other active ingredients into the skin.

Stability
Polyethylene glycols (PEGs) are generally stable. While specific pH stability for PEG-2 Rapeseedamine is not detailed, general PEG-lipid complexes have demonstrated stability at pH 8.5 but may destabilize around pH 5.0.
Conflicts
- Should be used with caution in formulations containing ingredients whose safety is based on their lack of dermal absorption, due to its potential to enhance penetration.
Safety
Safety Profile
The CIR Expert Panel has deemed PEG-2 Rapeseedamine safe for use under normal conditions, including it in a broader assessment of PEG derivatives. Previous concerns regarding use on damaged skin have been removed. While no specific maximum use concentrations for this ingredient were reported, general PEGs are considered safe when purified to eliminate impurities like ethylene oxide and 1,4-dioxane. Formulators must exercise caution due to its potential to enhance the penetration of other ingredients, particularly those where increased dermal absorption is a safety concern.
