@”DRBOB@VERDIENT.BIZ” HEC does have the problem as it started separating after a while, so I can’t really use it. I used ultrez 10 that working but still not able to improve the sticky feeling.
@EVchem I was reading the literature, it seems like Triethyl citrate not safe chemical for the skin. Maybe something else to take out the tacky feeling. I was thinking ethyl ascorbic acid but that almost double the cost of Sodium ascorbic acid. It will surely increase the overall costing.
