[quote="llerickll"][quote="staff"]Hello! The learning team recommends members. Try a mix similar to the ordinary
Vitamin C 8% +
Alpha Arbutin 2% ok
Vitamin C (L-ascorbic acid) (Ultra-Fine) 8%
Alpha Arbutin 2% 1,3-
Propanediol the rest to complete 100% may need to use a little heat to warm to help melt together easier formula like this Will last longer
Vitamin C (L-ascorbic acid) (Ultra-Fine), dissolved In water a lot because of stability problems as suggested by Mr. llerickll
Staff, I have tried following.
L-ascorbic acid insoluble in
Propanediol at all, warmed at 40c, then people are already (no blender, warm + people can stay 30 minutes) finally settled down and slept at the bottom of the container, but not serious. I used it myself anyway. When using it, shake the bottle first. And then suck it with a dropper. I really want to invade the lab The Ordinary and see how they can dissolve it completely. No suspension or precipitate at all
Please ask the staff for the solution.
L-ascorbic acid precipitates in the Glycol above (I have already done it). Get a little more thick (but still use a dropper) by purchasing
Oil-Fix -O to put 2% of the solution is to shake the solution in the bottle before giving
L-ascorbic acid does not lie at the bottom of the bottle, then slowly put
Oil-Fix -O one by one. A little bit and then shake the bottle continuously until it reaches 2%. Should it be a gel? I don't know if this method will work or not.
