jemolian said: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!

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.
