Brij S721

Brij S721 is a non-ionic emulsifier used in topical formulations to support the formation of stable oil in water emulsions and dispersions. It exhibits excellent tolerance to extreme pH conditions and high electrolyte concentrations and is particularly effective when used in combination with Brij S2 Pharma to generate robust liquid crystalline oleosome emulsifying systems. Typical topical usage levels are 0.5–5.0%.
