General description

Brij® O20 is a non-ionic surfactant that has an 18 carbon tail with a single double bond and the head contains 20 ethylene oxide moieties. It is polyethoxylated fatty alcohol that is hydrophilic in nature.

Application

Brij® O20 has been used:
  • as a detergent in medium A to prepare single detergent micelle aggregates
  • along with phosphate buffer saline (PBS) solution as the receptor solution for terbinafine (TBF) for in vitro permeation studies of TBF-free base in porcine skin
  • as a detergent to isolate detergent-resistant membranes from the mouse brain and to determine the distribution of major mammalian brain gangliosides, GM1, GD1a, GD1b and GT1b
