Do you think something like this would work, despite being advertised for homogenizing tissues & brains!

In the meantime, I am getting quotes from some contract manufacturers in the area.  For not much more ($1000-1500,) I can have professionals assist with the formulation in a real lab.  

Those starting formulas look nice, but I’m trying to achieve something that appeals to the all-natural, active crowd.  Only 5-6 organic ingredients + zinc, very sweat & water resistant, and sold in biodegradable packaging!

@belassi - my latest batch has a higher melting point, 95-100 degrees F.  More beeswax and butter, less of the oils.  It’s a “summer” formula  

@bob - from my research it seems like an entry level, high-shear mixers/homogenizer can be found for around $700-1000. 

It may be worth it to simply work with a contract manufacturer on the formulation… I just really want to do it myself!

@belassi - hmmm, why do you ask?  Depending on the formula, the stick starts melting somewhere between 80-90 degrees F.  

@bob - I respect your position, however these are for personal use & testing.  My goal is to create a formula that I approve of on my own, before having it made professionally, undergoing SPF testing, etc. 

Hopefully that eases your moral dilemma, if not perhaps someone else will chime in.

Thanks Bob.  Perhaps my electric hand mixer is not enough to provide a uniform suspension in the time I have before the formula begins to dry (2-3 minutes max).

Any idea what tool(s) would be good for this?  Something for home use rather than a commercial lab - like a stick blender?
