Science
Mechanism of Action
This ingredient operates by altering interfacial tension, acting as an emulsifier to stabilize formulations that combine immiscible liquids like oil and water. As a surfactant, it reduces the surface tension of water, allowing it to more effectively mix with and lift away oils and dirt from skin and hair, thereby facilitating gentle cleansing.

Transparency
Dusting Analysis
Meroxapol 105 serves a fundamental role in product formulation as an emulsifier and surfactant, essential for creating stable and functional cosmetic products. Its inclusion is typically driven by formulation necessity rather than being an 'added for marketing' ingredient.
The Formula
Formulation
Stability
While no specific optimal pH range for stability has been identified, it is noted that trace amounts of 1,4-dioxane, a by-product of ethoxylation, may be present. This can be managed through rigorous purification processes. Meroxapol 105, like other surfactants, is often formulated in combination with other surfactants to achieve desired performance characteristics.
