Science
Mechanism of Action
This ingredient works on the skin by forming a mesh-like structure, effectively creating a barrier that reduces transepidermal water loss and improves overall skin texture. As a surfactant, it lowers the surface tension between different substances, aiding in the formation of stable emulsions. It also acts as a solvent, assisting in dissolving and dispersing oil-based components within liquid cosmetic products.

Stability
PPG Buteth ingredients typically exhibit good stability in formulations, functioning effectively as solubilizers and solvents. It is important to note that small quantities of 1,4-dioxane, a processing by-product, may be present.
Safety
Safety Profile
The CIR Expert Panel has determined that the current data is insufficient to definitively support the safety of PPG-9-Buteth-12 for cosmetic applications. This conclusion stems from a noted absence of information regarding dermal absorption for lower molecular weight PPG Buteths, as well as a lack of specific data on skin irritation and sensitization. While the FDA includes the broader category of PPG Buteth ingredients on its list of approved indirect food additives, this relates to their use in food contact polymers rather than direct cosmetic application safety.

Verdict
While offering potential benefits for skin conditioning and formulation stability, the current lack of comprehensive safety data from the CIR Panel renders its overall verdict as insufficient-data for widespread cosmetic use.
