Poloxamine-702, also known as Tetronic 1107 or Polyurethane-702, is a nonionic surfactant and emulsifier used to stabilize formulations and improve product spreadability, particularly in cosmetics. It is an amphiphilic block copolymer made from poly(ethylene oxide) and poly(propylene oxide) blocks, with a central tetrakis(propanol) unit containing two tertiary amine groups that provide temperature and pH sensitivity.

Key Characteristics:

Nonionic Surfactant: It does not carry a charge, making it less reactive and more compatible with various ingredients.

Emulsifier: It helps to mix and stabilize ingredients that normally wouldn't mix, like oil and water.

Amphiphilic Structure: It has both hydrophilic (water-loving) and lipophilic (oil-loving) parts, allowing it to bridge between water and oil phases.

Temperature and pH Sensitivity: The central amine groups make the molecule sensitive to changes in temperature and pH, which can affect its properties.

Common Applications:

Cosmetics: Used in various personal care products like skin wipes, cotton balls, and cosmetic wipes to enhance skin health benefits and improve product consistency.

Emulsions: Can be found in oil-in-water emulsions, which are common formulations for many cosmetic products.

Wipe Products: A component in the liquid composition of wet wipes for personal cleaning, household, and industrial use.
