  Increasing spreadibility in serum

  Posted by pekkle271 on February 18, 2021 at 6:27 pm

  Working on an aqueous serum that has glycols and water at a specific ratio and needs to stay that way.  Is there anyway to improve spread of the serum by adding in an ingredient at a low level?  Would prefer no silicones.

  Got anything against PEG-esters? Plenty of them and most will accomplish your goal.

  Nothing against PEG-esters.  Do you have one that is commonly used or a supplier?  Thanks for your help!

  Some polymers provide some pretty good spread also - polyacrylate crosspolymer-6 for example.
