Which ingredient is making this so sticky?
Formulators!
Does anyone know which ingredient(s) is causing this to be so sticky?Thanks for any thoughts you might share.sodium lactate (liquid) 3%DL panthenol (powder) 3%sodium hyaluronate 0.2%Laureth 23 3% (POE (23) lauryl alcohol)glycerin 1%ferulic acid 0.5%mixed tocopherols (95%) 1%propylene glycol 30%L ascorbic acid 20%Germall plus liquid 0.5% -

Possibly the panthenol.

It’s the panthenol, the tocopherols and the glycerin … All are sticky. You can cut the panthenol down to 1% and the tocopherols of 0.5%. Also, you can eliminate the glycerin if you want to . That will cut down on the stickiness quite a bit.

I re-made a hand cream recipe that also had 3% panthenol in it in the past, but I used only 1% panthenol It is MUCH less sticky.
I had no idea panthenol in a powder form would make it sticky. Ain’t chemistry grand?Thanks for the help! -
Sodium hyaluronate is very sticky as well. Even at 0.2%.
-
In truth, you could probably use even less Panthenol.
-
Propylene glycol is actually a humectant, so you don’t need to use so much glycerin and panthenol, unless you’re using the former for more than just its humectant properties.

Laureth 23 can make a formula sticky, especially at 3%. Are you trying to make a skinceuticals knock off?
-
This is one of those occasions where a knockout experimental series really shines. In this case, for example, you have several ingredients that are probably making your formula sticky. Run the experiments and evaluate each for skin feel.

Indeed Bob. Here’s the link explaining how you do a knockout experiment.
