About
Steareth-27 is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.
Steareth-27 is a non-ionic surfactant consisting of stearyl alcohol polymerized with approximately 27 moles of ethylene oxide. It functions primarily as an emulsifying agent and surfactant in cosmetic formulations. Under EU cosmetic regulation (EC 1223/2009), ethoxylated surfactants may require testing for 1,4-dioxane impurity, a known potential contaminant from the ethoxylation process; however, Steareth-27 itself is not subject to specific restriction listings in the EU Cosmetics Regulation annexes.
Skin benefits
- Effective emulsifier for oil-in-water formulations
- Improves texture and product spreadability
Known concerns
- Potential 1,4-dioxane impurity from ethoxylation process
- May be sensitizing in susceptible individuals at high concentrations
