Science
Mechanism of Action
As an amphiphilic block copolymer, Poloxamer 282 possesses both water-attracting (hydrophilic) and oil-attracting (hydrophobic) segments. This unique structure enables it to reduce surface tension between immiscible substances, facilitating the formation of stable emulsions. In cleansing formulations, it aids in dispersing and suspending oils and dirt, allowing them to be easily rinsed away with water. It also enhances the solubility of ingredients that are otherwise difficult to dissolve in a given solvent.

Stability
Poloxamers are robust materials; their aqueous solutions demonstrate stability across a range of pH conditions (acids, alkalis) and in the presence of metal ions. However, aqueous solutions can support microbial growth, specifically mold, necessitating appropriate preservation. Bulk material should be stored in a cool, dry, well-closed container. This ingredient can also form thermo-responsive hydrogels under specific concentration and temperature parameters.
Conflicts
- While specific data for Poloxamer 282 is limited, other poloxamers, such as Poloxamer 188, have shown potential incompatibilities with phenols and parabens, particularly depending on their relative concentrations. This suggests a general consideration for the poloxamer class when formulating with these preservatives.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Poloxamer 282, and other poloxamers, safe for cosmetic use, anticipating minimal and slow skin penetration due to its molecular weight and solubility, despite an absence of reproductive and developmental toxicity data. Moumoujus adheres to industry best practices, ensuring purification procedures maintain impurities like ethylene oxide, propylene oxide, and 1,4-dioxane below established safe limits. Poloxamers are also recognized by the FDA as approved pharmaceutical excipients.
