Interested in opinions... Will this sort of thing create emulsifier free nanoemulsions?

It's become quite popular in the molecular gastronomy movement. Would love to experiment with the concept for cosmetic emulsions on a small scale without giving my right arm to buy the set up.

    Seems a bit battered to have only a 5% price reduction from new.

    Indeed, there are a few cheaper ones. Based on the manual online, I'm guessing this one is from 1998. The cheapest new models I could find are in the 3k range. 

    Sounds like it should work although it's a bit unclear as to whether a microtip will be able to emulsify say a 500 ml sample size on its own. Wondering if I need a different horn/tip set-up...

    It's easy to create emulsifier-free nanoemulsions. Getting them to stay stable for more than 3 or 4 minutes, however, is a real challenge.

  • @Bobzchemist - Would having hydroxypropylmethyl cellulose predispersed in the aqueous phase, sonicated the two phases and then heating to just past the gellification temp of hpmc to "set" it work?
