Polyquaternium-51 (PMB)

Polyquaternium-51 is a biomimetic moisturizing polymer designed to mimic the structure of phospholipid membrane. It has unique amphiphilic structure and could anchor into the stratum corneum, exhibiting an adaptive moisturizing effect on skin. In the meanwhile, Polyquaternium-51 protects the skin from environmental aggressions: Improving the barrier effect, and reducing the Trans Epidermal Water Loss.


· Long-term adaptive moisturizing.

· Suppresses irritation from surfactants and peeling agents.

· Reduces the Trans Epidermal Water Loss.
