Water is an ingredient that can dissolve soap. Water is a solvent and the the soap is the solute. Solutes are things that dissolve in solvents. I'm not sure what you're asking about an ingredient, but water makes all soap dissolve.
Soaps are made of molecules that are both fat and water soluble. The molecule has a long hydrocarbon tail that allows it to dissolve grease, and a polar head that is water soluble. A soap molecule. The grey, red, and white balls represent carbon, oxygen, and hydrogen atoms, respectively. The sodium ion near the negatively charged oxygen atoms is not shown. The head is the sodium or potassium salt of an organic acid.
