    I’m still observing the performance of the K-20W over a few days.

    I added too much by accident, so it was 3.5%, for initial observation, it seems that is increases glide and also detacks the humectants significantly. Previously my pillow case would stick to my face slightly but with the K-20W, it seems totally fine. I probably can readjust the other ingredients accordingly to increase humectancy. 

    Glad to hear you are liking it.  I now use it in all my products…hehehe…even my mosquito lotion (fragrance fixative).  It will be part of the face creams I will start developing this week.  Hehehe…hope it doesn’t take me a year…like my last two projects!

    Xylitol is quite good. It’s a sufficient humectant and easy to buy, though could be tacky at high level same as glycerin…

    Evaluation of xylitol as an agent that controls the growth of skin microbes: Staphylococcus aureusStaphylococcus epidermidis, and Cutibacterium acnes


    Please note that Xylitol is a well known fatal toxin for dogs in *trace* amounts - the canine system perceives that sugar alcohol as an overdose of glucose and releases deadly quantities of insulin. AFAIK this effect cannot be reversed once started.

     I check ALL food and skin products for xylitol and will not bring them into my home. I volunteered at an animal shelter for many years and watched a dog die of trace xylitol exposure once. It was an extremely painful experience to watch that young puppy suffer and die.

     Anyone who has ever had a dog knows that dogs lick the skin of the humans they like and love. I have no idea why anyone would ever take a risk putting dog poison in skin care products, except if they don’t know about it.
