What to do if liquid soap changes color?

The active ingredient of soap is higher fatty acid salt, which is relatively stable, and the pigment and other additives may have been oxidized, but the soap can still be used.

Handmade soap tends to oxidize and turn an unsightly brown in direct sunlight. Although the soap has changed color, the sodium fatty acid molecules in the soap, which play a role in decontamination, have not changed much in principle. Therefore, it can be used to remove stains on the surface of stainless steel, ceramics, or glass during household cleaning.
