Question

Why are most whitening ingredients not stable or effective in bar soap formulations with high pH?

Answer

Based on the previous information, most whitening ingredients are not stable in the high pH environment of bar soap. Adding them to bar soap would likely result in them losing their effectiveness or potentially breaking down into harmful substances. Therefore, it is generally not recommended to add typical whitening ingredients to bar soap formulations.
