Science
Mechanism of Action
This ingredient's unique amphiphilic structure, comprising both hydrophilic (water-loving) and lipophilic (oil-loving) segments, allows it to effectively reduce surface tension between immiscible liquids. This property facilitates the formation of stable emulsions, enabling the homogeneous dispersion of oil and water components. In cleansing applications, its mechanism involves binding to oil and particulate matter, allowing them to be easily rinsed away with water.

Formulation
Stability
Poloxamers are block copolymers whose stability can be compromised by factors such as elevated temperature and humidity. These conditions may induce degradation, potentially leading to the formation of acidic compounds (e.g., formic, acetic acid) and aldehydes (e.g., formaldehyde, acetaldehyde), which can alter pH. They generally exhibit stability around physiological pH (7.4) and in mildly acidic environments (e.g., pH 5.5) particularly in hydrogel systems.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Poloxamer 231 safe for use in cosmetics, specifically within concentrations up to 20%. Its molecular weight and solubility suggest minimal skin penetration. The FDA also acknowledges poloxamers in indirect food additive applications, and Poloxamer 188 is approved for OTC wound cleansers. Rigorous purification is crucial to maintain impurity levels (ethylene oxide, propylene oxide, 1,4-dioxane) below regulatory thresholds.
