Surfactants- Brij 35

[enrico]

Hello everyone

I am working with surfactants to develop a cleaning system for helicopter's turbines and I wanted to ask you a question ... I use a variety of different types of surfactants including CTAB, CTACL, sarcosine and Triton, and when I prepare aqueous solutions, they appear clear ... but I have a question on another surfactant named Brij 35 ... you think it is normal that an aqueous solution of 5 mL 0.05 M Brij 35 appears white and not clear?...and when increasing the concentration becomes very viscous gel?

Sorry for the bad english, i'm italian

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.
