How many % of Brij 35 over the total volume? It is white and clear in the beginning because it is not dissolved yet. Try heating while dissolving and it should be clear. Viscosity will increase after adding Brij 35.

Hi all, I need help here. I am working on amino acid-base surfactants. After I prepare the solution (mixture of anionic and nonionic surfactants) and keep it at low temperature (5degC), lumps start to form which I suspect it is caused by the amino acid surfactants. Any solutions to eliminate the precipitation at low temperature? Thanks. SL.
