How do you keep cetyl alcohol in suspension?

I'm using cetyl alcohol and Tween-20 as a mild non-ionic shampoo.  After heating it up, it makes a nice white creamy colloid/suspension, but after a couple weeks, it gets watery and grainy as the cetyl alcohol precipitates out.

Any ideas how to get it to stay in suspension?  I used a commercial product that had a seemingly infinite shelf life!  I went through the short course, but it didn't really give me any ideas on where to start...
