  Humectants

  Is there any humectants that work immediately on the skin? For hand/shower-gel, the humectants is washed away after 20 sec.

  What about water?
  Seriously, what exactly is your question and where’s your level of knowlege (not an insult but a basis to build upon)?

  @Pharma you are so on it there. Kudos to you. Best humectant known to mankind: a swim. Now, @tinas you are no doubt experiencing what happens when you try to use glycerin in a detergent cleansing formula such as body wash? Am I right? Here’s the answer: NOTHING. Glycerin wants to be an effluent in that situation, not a humectant. Use a polyglyceryl ester or the Old School PEG-7 glyceryl cocoate or even polyquaternium-7 or 10.

    glycerin is waste of money, but what about urea?

      In a cleansing product, an even bigger waste of money. Urea is more water loving than Glycerin. The story is different if you talk about a leave-on product, like a body cream.
