Cosmetics Formulation Development

Hello, i am having alot of issues with solubilizing a o/w serum with main actives of

Oil phase Actives
2% Tocotrienols, 0.5% CoQ10 Pure &  3% Ascorbyl Tetraisopalmitate 

Water phase Actives
15% L-ascorbic acid 
10% DMI
10% pentylene glycol
5% 1, 2 Hexanediol 

Equipments
Magnetic Stirrer
Hot plate
Precision weighing balance

I am hoping to use Emulsifier / solubliser that is clean and EWG green.. Also, the best if no heat is involved... Is Homogenizer necessary to make sure the oil does not separate? I have tried even with Polysorbate 20 & 80 but after awhile the oil still separates...

Please help - im a recent buyer and even travelled to your shop for self collection. Thank you!

Hi,

I assume that the remaining content of your formulation above is water.

The formulation isn't easy to emulsify because of low pH from ascorbic acid.

We suggest you can try Butter Cream Maker 3% to emulsify it. It will be stable. However, you will need to use heat but you can add heat-sensitive actives in the last (cooling-down) step.

It isn't easy to use Magnetic Stirrer to mix. Most likely you will need a stronger mixer. At least Overhead stirrer is required.

Thank you so much for your reply. I will make an order now.
For Homogenizer with high shear, do you have such equipment? especially stator with very small holes so that the oils can break even smaller

Yes we have several sizes of Homogenizers. You can choose the one that suitable for your production batch.
