Gina, it was mentioned years ago on The Dish forum. I was sooooo sick of lining moulds - it took me longer to line moulds than to make the soap. After researching and checking with a company here in NZ (it is difficult to find), the lovely gentleman suggested I use potassium lactate as it was much milder and I would achieve the same outcome. No need to line my formica moulds and as a bonus would contribute to the hardness of my bars. The forum suggested it would decrease lather and scent - it does, but not so much that it matters. It takes so little - had a bit of experimenting to do when first using. Use too much and you will get chalky white crumbly bars. I also have one of those clear plastic divider thingies. I used the mould and perspex dividers once and haven't used them again. Got from Aussie. Maybe I will try again. Welcome Maggie - lovely to hear from you. Welcome lurkers - please join in! Well it is a soaping day and must get on with it! Have a good day all.

I to will be researching this now though i have moved to silicone molds but for swirling i would like to use my hard plastic clear mold (its early and i cant think of the correct word) but find it a pain to get soap the right shapes and the liner leaves marks on the soap. Welcome Maggie to the list. By the way all there a few lurkers on the list following hopefully the debate and outcomes. Gina Roberts Soapcraft www.soapcraft.co.nz
