Science
Mechanism of Action
This ingredient reduces the interfacial tension between immiscible oil and water phases, facilitating the formation and stability of emulsions. Its antistatic action helps to neutralize static charges.

Dusting Analysis
PEG-15 STEARAMINE serves a foundational role in formulation stability rather than delivering specific active skin benefits, thus it is not typically 'dusted' as an active ingredient.
The Formula
Formulation
Stability
Polyethylene glycols generally exhibit excellent skin tolerance and are not prone to microbiological degradation, often negating the need for additional preservatives. While a specific pH range for PEG-15 STEARAMINE is not reported, related PEG derivatives demonstrate stability and efficacy across both acidic and alkaline formulations.
Safety
Safety Profile
The CIR Expert Panel deems PEG cocamine and related ingredients, including PEG-15 STEARAMINE, safe for cosmetic use under current practices when formulated to be non-irritating. Notably, PEG-15 STEARAMINE itself was not widely reported in use as of 2015. Broader PEG Stearates have been found safe up to 25% concentration without causing irritation or sensitization in clinical studies. There is a potential for trace amounts of 1,4-dioxane, an ethoxylation byproduct, which manufacturers should minimize to ensure safety, especially when products are applied to compromised skin.
