Lotion goes liquify!
Hi, today I decided to make a lotion with Dermofeel GSC palm oil free, wich I have had since a long time, but I have never had a success with it. Here is my basic formula :* Gliceryl stearate citrate - 3%* Behenyl alcohol - 3%* Myristyl myristate - 1%* Cetiol Ultimate - 2%* Isoamyl laurate - 2%* Olive sqvalane - 2%* Caprylic capric triglycerides - 4%* Refined Mango butter - 3%* Water - 70%* Allantoin - 0.5%* Glycerin - 2%* Sodium PCA - 2%* Sodium lactate - 2%* Pentylene glycol - 2%* Preservative - 1.5%I heated the water and oil phase, then I mixed the oil in water, and stirred with stick blender for 5 minutes. After that I switched to hand mixer until it cools down. Everything was fine, the emulsion became thick and nice, but when I added the cool down phase ( Sodium PCA, Sodium lactate and Pentylene glycol), I added them at once, and the lotion became watery immediately, but without separatation.
I checked the Ph value with Ph paper, and it was 6. I guess it is normal Ph value for a lotion. I am curious wich ingredient could make the lotion watery. I suppose it could be Sodium lactate or Sodium PCA, but I am not sure wich one. As I know the Pentylene glycol is used as a thickener, so I guess it can’t be the reason.Any ideas?PS after 30 minutes the lotion has separated!
