Science
Mechanism of Action
This ingredient operates by decreasing electrostatic charges on surfaces, providing antistatic properties. Concurrently, it acts as a surfactant, reducing surface tension between immiscible liquids like oil and water, thus enabling the formation and stability of emulsions.

Key findings
- 01 In vitro studies, not directly relevant to skin, demonstrated a concentration-dependent reduction in active Streptococcus mutans biofilms. Experimental mouth rinses containing 1.2536% showed a 57.5% reduction, 0.6268% yielded a 33.5% reduction, and 0.3134% resulted in a 16.9% reduction.

Dusting Analysis
There is no available data to indicate that PEG-3 Tallow Aminopropylamine is commonly dusted or presents specific dusting concerns in cosmetic formulations.
The Formula
Formulation
Stability
Polyethylene glycols (PEGs) generally exhibit a wide range of viscosity and solubility. PEG-3, being a lower molecular weight PEG, typically shows water solubility, which may decrease with increasing molecular mass. A related ingredient, PEG-2 Hydrogenated Tallow Amine, is soluble in both water and organic solvents, with a reported pH range of 7-9 for a 1% aqueous solution.
Safety
Safety Profile
The CIR Expert Panel assessed PEG-3 Tallow Aminopropylamine and related PEG derivatives, concluding they are safe for use under current practices when formulated to be non-irritating. An earlier assessment from 1999 found insufficient data for ingredients specifically named with PEG-2 through PEG-5, but this was superseded by a more comprehensive 2015 assessment. Concerns regarding safety increase for inhalable product forms due to potential respiratory issues, or if the ingredient contains toxic impurities. While no specific maximum concentration was identified for PEG-3 Tallow Aminopropylamine, a related ingredient, PEG-15 cocamine, was reported with a maximum use of 3% in leave-on dermal products. This ingredient lacks explicit FDA cosmetic status, though 'peg tallow amine' is noted in an inventory of food contact substances.

Verdict
PEG-3 Tallow Aminopropylamine serves as a functional emulsifier and antistatic agent in formulations; however, its specific efficacy and compatibility for direct skin benefits remain largely unstudied in relevant dermatological contexts.
