Science
Mechanism of Action
OLETH-45 operates by reducing surface tension between immiscible liquids, acting as an emulsifier to stabilize oil-in-water or water-in-oil emulsions. As a surfactant, it can help cleanse by lifting dirt and oil. Its solubilizing properties allow it to disperse challenging ingredients, such as fragrances, within a formula. Furthermore, research on related Oleth compounds suggests a potential role in enhancing the transdermal delivery and permeation of other active ingredients into the skin.

Stability
Similar Oleth ingredients exhibit sensitivity to high pH, which can lead to hydrolysis. For optimal stability and longevity within a product, formulation in a neutral to slightly acidic pH range is suggested.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed OLETH-45, within a broader group of 131 alkyl PEG/PPG ethers, as safe for use in cosmetics under current practices and concentrations, provided formulations are designed to be non-irritating. A by-product of its manufacturing, 1,4-dioxane, may be present in trace amounts, though purification processes can effectively minimize this. No specific SCCS opinion or FDA cosmetic ingredient status for OLETH-45 was identified.
