Cosmetics Formulation Development

Hello, I would like to ask if the serum is produced from substance -water 95.5% -HEC 1% - กลีเซอรีน 3% -Glyden 0.5% will get the perfect 100% ratio. If you want to bring gel from Aqua 99.08% Cabomer 940 0.1% DMDM 0.03% add extract and น้ำหอม 0.79% more, bring the meat together. and after that add the extract to the formula. I want to know: Is there a chance of losing it or not? or cannot be mixed together

Hello, because the team may not have expertise in the ingredients that members use. The team tries to answer as much as they can. Usually, water gel texture, although using สารสร้างเนื้อเจล , different types should (most likely) be compatible. by mixing them together directly Like water with water, it can be easily noticed. By experimenting with a small amount of mixture, if you don't understand, you will find that there is a separation from the inner layer immediately. but if they match will be compatible as usual And there will be no separation in the future for สารกันเสีย provided Calculate the final ratio After mixing them together remaining concentration of สารกันเสีย and check how much concentration of สารกันเสีย is it enough? (Check the manufacturer's recommended usage rates) for infection control. If sufficient, no additional additions are required. สารกันเสีย again. It must be added to the level specified by the manufacturer. (but should not exceed the level specified by the FDA for สารกันเสีย that kind)
