Thank you SO much for sharing your thoughts on Saccharide Isomerate. It’s not exactly inexpensive so I’ll pass for now.
So far my favorites are Propanediol and Sodium Lactate. Both are non sticky, especially Propanediol. Actually Propanediol has an almost emollient feel. And I find it extremely effective as a humectant.
I’m also a fan of Amino Acid blends, such as the one sold by Formulator Sample Shop.
I’m buying some Hyaluronic Acid right now. Going to make a 1% solution. I’ve found that in prepared products, Hyaluronic Acid is way too sticky for me. So I’m going to try it alongside some ingredients known to detackify - Propanediol and dimethicone, and use it in small concentrations.
I’m also trying Honeyquat and hydrolyzed proteins to see how they compare.
