The bars made, which are essentially free of water, are of improved thermal stability, allowing them to be stored at higher temperatures than comparable bars, without distortion, and do not readily form inhibiting gel structures or coatings after use, which could otherwise diminish foaming power. Also within the invention is a method of making the described detergent bars. | |
