What it is
Meroxapol 172 is a synthetic block copolymer, part of the poloxamer family, designed to act as a surfactant and emulsifier in cosmetic formulations.
How it works
It lowers the surface tension between oil and water, allowing them to mix into a stable emulsion. This helps cleansers lift dirt and oil from the skin and helps lotions feel smooth and uniform.
Pros
Gentle on skin
Meroxapol 172 is considered low-irritation, making it suitable for sensitive skin types in rinse-off products.
Improves product feel
It helps cleansers and lotions spread smoothly and rinse off without leaving a sticky or greasy film.
