@chemicalmatt that makes fully sense. Appreciate you sharing your experience and methods.

 @GeorgeBenson, it is IKA blades.

@chemicalmatt, that is a fantastic idea with the Kitchen Aid. Thanks a lot. Do you think that the whisk attachment would bring too much air into the w/o emulsion? Or is it something not to worry about?

Ah, sorry, I missed answering on your question. I use cold process. I add preservative eco 1388 to the water phase. Here is the producer’s reco in case of this combination with GMCY. “Note: In Combination with dermosoft® 1388 / anisate or alkaline presolutions, addition to
the oil phase is recommended.”

Thanks for your recommendations.

I have not experienced sweating if there was no wax, butter added. I actually find Neocare a fab emulsifier for gorgeous velvety skinfeel. It seems that I managed to fix this issue with proper mixing. Centrifugal test showed no stability issue. Another one follows in a week.

I will also check Isolan GPS. Thanks.

Just one last question; adjusting ph after adding Mg Stearate? I would add it to the oils, and I adjust the ph of the water phase before emulsification. Can you please let me know what you meant related to Mg Stearate? Thank you.

[BettiB]

Thanks for your detailed answer. Really appreciate it. 

What would you use insetad of GMCY? I read that in the water phase it needs a solubilizer, that is why it was added to the oil phase. 

I was thinking of adding magnesium stearate at 0.3% to the oils, I would like to avoid wax or butter. I feel like the skin is sweating under.

Gelling water with a gum, you mean?

Thank you.

Ah, ok. Thank you.

Sorry for asking back, but what does LOI stand for? Google was not helpful.

I use Neocare in cold process. I add water phase drop by drop to the oil phase and slowly mix it after each addition. Afterwards, slowly mixing for 30 mins.

This emulsifier does not like homogemization.
