Only 3% is enough for medium makeup, foundation, loose powder) - Propylene Glycol how many percent? - Water until it reaches 100 - Phenoxyethanol 0.5% 2. If you want to mix cleanser, use to wash your face without bubbles. Wash and feel clean, not dry, tight, like a famous brand and quite expensive (cetaphil gentle skin cleanser ), a famous brand of cleanser ingredients Water Cetyl Alcohol Propylene Glycol Sodium Lauryl Sulfate Stearyl Alcohol Methylparaben Propylparaben Butylparaben Ingredients to mix by yourself - Water 100% complete - Cetyl Alcohol How many % should I use? - Propylean Glycol uses glycerol. Can I use seryl instead? How many % is good? - Sodium Lauryl Sulfate instead of Coco Glucoside 5% is enough for morning and evening facial cleansing (after Cleansing Water) - Stearyl Alcohol Not sure if this is necessary? but not on the website for sale If necessary, what should be substituted? What percentage - Methylparaben - Propylparaben - Butylparaben สารกันเสีย 3 sides on, instead of Phenoxyethanol 0.5% (or should you put 1%? Hot flashes, a little burning and then disappears)

more want the product that has a slippery appearance when used to reduce facial friction. Use Propylene Glycol or Glycerin ok, how much is good? In both products, thank you.

Hello,

Ingredients to mix by myself. (Cut off all the skin care parts because they are on a single page) - MakeUp-Wash™ 3 (used as a cleaning agent. Only 3% is enough for medium makeup, foundation, loose powder) - Propylene Glycol how many percent? - Water until it reaches 100 - Phenoxyethanol 0.5%

recommend Propylene Glycol starting from 10%, the reason why it is recommended to use a lot. because it can help catch makeup as well to increase the efficiency MakeUp-Wash because if using MakeUp-Wash much, cost will be high, while Propylene Glycol much cheaper

Ingredients to mix yourself - Water 100% - Cetyl Alcohol how many % are good? Yes. - Propylean Glycol. Can I use glycerol instead? How many % is good? - Sodium Lauryl Sulfate instead of Coco Glucoside 5% is enough to clean the face in the morning and evening (after Cleansing Water) - Stearyl Alcohol. Not sure if this is necessary? but not on the website for sale If necessary, what should be substituted? What percentage - Methylparaben - Propylparaben - Butylparaben สารกันเสีย 3 sides on, instead of Phenoxyethanol 0.5% (or should you put 1%? a little hot flashes and then disappears)

If you have an allergic reaction to Phenoxyethanol is recommended. Mild Preserved Eco 1% instead. yes
