Science
Mechanism of Action
This ingredient operates by significantly lowering the interfacial tension between immiscible oil and water phases. This reduction in surface tension facilitates the uniform dispersion of one phase within the other, leading to the formation of stable emulsions.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel determined that alkyl PEG ethers, including MYRETH-2, are safe when formulated to be non-irritating. A critical consideration for formulators is the potential for contamination with 1,4-dioxane during the manufacturing process, a substance classified as a Group 2B suspect carcinogen by the IARC.

Verdict
While MYRETH-2 is effective as an emulsifier for product stability, its classification as 'safe with restrictions' by CIR, alongside the potential for 1,4-dioxane contamination, necessitates careful sourcing and formulation practices.
