I’m coming today with a question about stability
I’ve tested one of my products and it keeps on failing the freeze/thaw test.
Emulsion didn't separate but the texture changed.
It passed incubation at 45*C for 2 months ( ongoing test) and centrifugation (warmed to 50*C and spun for 30 mins at 3000rpm).
The formula for this product is very simple:
Montanov 68 3%
Eumulgin SG 0.5%
Solagum AX 0.2%
Shea butter 3%
cetyl alcohol 2%
Pentylene glycol 3%
1388 eco 4 %
Lactic Acid. 0.35%
Water up to 100
I would be very grateful if you could share with me your experience and thoughts.
Thank you in advance.
