Guest guest Posted February 1, 2008 Report Share Posted February 1, 2008 Dear Mdm, The blue colour that you use to colour your soap - is it a dye or an optical brightener ? There is a blue coloured optical brightener we use in this side of the world (South East Asia), it's been around for ages, over 40 years easily. This optical brightener happens to be blue in colour. When used in washing, it makes your whites look brighter. The apparently dark blue colour of the item washes off easily and doesn't stain. Could it be you used blue dye instead of the brightener ? I could send you some from over here with usage instructions, but postage is a killer. malaysia to ??? If you need help in making it, be glad to assist but we make liquid soaps here(as in the place I work), much less residue after washing. Easier to dissolve & better efficacy. The formulations are suitable even for those with sensitive skin and handles delicates (silk, sarees,scarfs, traditional dresses) effectively while taking out the nasty stains e.g. food, grease, ink. may your week be joyous, you can contact me if there is anything else I can help with : personal email : altykthong@...
