How many days does it last after mixing? I mix all the ingredients together in water
.
สารกันเสีย can last at least a year. But it's definitely not, it depends on the environment. storage and many other factors I looked at your formula and found that there is
Phenoxyethanol 0.3% vs
1,2-Hexanediol 3% and the built-in of
Double Hyaluron Liquid is also preserved
Phenoxyethanol again, which I think is enough to control the disease. And if you do it yourself, not much at a time, you don't have to worry about the age of the product at all because it's gone for a while. But as I see in the market, most of them claim to be 2 years old from the date of manufacture. But if you open it, it can last for about 6 months, but in the end, you can't set the expiration date for sure, just guessing. And if we're going to sell it, we see Mr. C7 and Staff suggest that we need to send a lab to inoculate whether our products can control the disease or not. Where is the mistake, wait for the staff to add again.
