  How to make o/w emulsion

  Posted by Bluebird on August 25, 2024 at 6:33 am

  Is the best way to use a cosmetics homogenizer?

  The total oil content will be low-ish, lower than 1% total.

  Is there a reliable way to make such an o/w emulsion without the use of a homogenizer?

  I suppose a solubilizer like Tween may work but I’m sensitive to Tween.

  Is there any other way to make an o/w without a homogenizer and without a solubilizer?

  I cannot think of anything (except, maybe, using liposomes?) but asking just in case there is another way.

  You could make a microemulsion or use an ultrasound device, but the first requires advance knowledge on colloid chemistry (and specific type of surfactants), and the second requires special equipment.

  Now, an oil phase of 1% migh not be worthy to make an emulsion, but if so, there are plenty of emulsifiers other than polysorbates (which are actually pretty safe), some in liquid form and/or water dispersible.
