Brij™ S721 owes its performance capabilities to the superior emulsifying characteristics of stearyl alcohol as the lipophile and the unique distribution of ethylene oxide chain lengths. The ethylene oxide distribution ranges from very short to very long chain lengths in contrast to the normal Poisson distribution for ethoxylated products. The nonionic nature of Brij™ S721 enables it to be used in combination with other ingredients across a wide pH range. It is a stearyl alcohol for use as a wetter, dispersant, emulsifier, and emulsifier O/W.
