Hi, I am very ignorant in the mysteries of chemistry and am attempting to find a supplier of salicylic acid for my home made glycerine soaps. I have run batches with percentages from .5% to 2%.
Between suppliers the end result is very different in;
- strength: measured by the dryness experienced by those who used it
- fragrance: (note my test batch soaps are un-fragranced. However the normal natural fragrance was changed by both suppliers in different ways. For one supplier it seemed there was no longer any fragrance, for another it had a mild unpleasant chemical smell.
- hardness: both suppliers created a harder dryer soap than without SA. One was harder than the other.
- clarity: Note that I only used clear soap in one test for one supplier. Within a few days the clear soap was almost undistinguishable from a normal white soap (Titanium Dioxide is used for a whitener)
I will say that my soap is very finicky. I have had suppliers change their sorbitol process/ingredient for example and it ruined batches of soap. I am using the standard (non-pharmaceutical) SA. If anyone can tell me why different manufactures are behaving differently I would greatly appreciate it.
