Polyglyceryl-4 caprate
CAS 160391-93-5
No ionic charge is required: polyglyceryl-4 caprate uses hydrogen-bonding glycerol units and a C10 tail to negotiate the oil-water boundary.
Polyglyceryl-4 caprate is a nonionic surfactant built from a water-loving polyglycerol head and an oil-loving C10 fatty chain. The molecule can sit at oil-water interfaces and stabilize emulsions without carrying a permanent ionic charge. "Polyglyceryl-4" describes an average oligomeric family, not one exact molecule. Its chemistry shows how formulators tune amphiphiles by independently changing the hydrophilic head and hydrophobic tail.
