  Hi, can I use polyquaternium 7 for a leave on skin product? What concentration is more suitable?
  thanks

  Absolutely you may. This leaves a soft non-matte film on the skin. I’ve formulated PQ-7 into shave and after-shave products for years. Does not hurt foam on the “shave” end, leaves a nice skin feel on the “after” end. Steer clear of anionic emulsifiers if it is to be a cream or lotion. Using the typical 10% active commercial product you don’t need much more than 2.00% w/w either.
