Science
Mechanism of Action
As an emollient, Myreth-3 works to soften and smooth the epidermal surface, contributing to improved skin texture. Its skin conditioning properties help maintain the overall health and appearance of the skin. Additionally, it functions as a surfactant, effectively lowering the surface tension within formulations to facilitate the uniform dispersion of oil and water phases, thereby enhancing product spreadability and absorption, resulting in a lightweight, non-oily finish.

Safety Profile
While a direct Cosmetic Ingredient Review (CIR) assessment for Myreth-3 is currently noted as having insufficient data, the broader class of polyethylene glycols (PEGs), to which 'Myreth-' derivatives belong, generally demonstrates a favorable safety profile. The Environmental Working Group (EWG) assigns Myreth-3 a 'LOW' concern for cancer, allergies, immunotoxicity, and developmental/reproductive toxicity, confirming its absence from their Restricted or Unacceptable Lists. Furthermore, the European Chemicals Agency (ECHA) reports that 36 out of 36 companies classify it as 'Not Classified' under GHS hazard criteria.

Verdict
Despite its emollient and conditioning benefits, the high comedogenicity rating makes Myreth-3 an unsuitable ingredient for precision skincare, particularly for individuals prone to breakouts.
