surfactant fall-out

[Tom Paterson]

Hello
I would appreciate any help with the following problem:

I have a friend who has a solution containing 0.19 M NaOH and 0.045M
SDS (Sodium Dodecyl Sulfate), pH approx. 13 .  How does my friend keep 
the SDS in solution @ temp. less than 19 degrees C?

Thank you in advance
