Use Phenoxyethanol SA for herbal soap กรีเซอรีน Yes, the blending method says it must be used at temperatures below 60 degrees and values ph2.0-6.0 The question is that when we mix สารกันเสีย at lower temperatures 60 degrees and then pour กรีเซอรีน I couldn't post it in time. He hardened. Here we warm it up. dissolved สารกันเสีย exposed to temperatures above 60C. Shows that he will lose efficiency. then we have to fill สารกันเสีย put in again? Will it still be effective? Thank you.

Hello, according to the information that members have informed. "Fresh herbal soap and powder" The problem should be here and it's important. I don't know where the members brought the fresh herbs and powders from. And what is the disinfection process? And have you ever measured the infection (Plate Count) after sterilization? The introduction of fresh herbs in any cosmetic formula. can't be easy because there will be an infection If not properly disinfected first, using สารกันเสีย is only to suppress the growth of infection But if the infection is high, using สารกันเสีย on the level that the FDA is permitted to use will not be enough Against infection control in formulas that have a lot of infection from fresh herbs (using สารกันเสีย in high doses may be able to control the infection in this case. But it is against the terms of the FDA.) In the part where members encounter problems that use Phenoxyethanol can't control infection because Phenoxyethanol Normal, not very active In fungal control, the team guessed that The germs that the members found Probably a fungus
