ABSTRACT:
Toilet soap bars, preferably milled and plodded, made from topped, distilled coco fatty acid, which is partially saponified, are superior to tallow-coco soaps and palm oil-palm kernel oil soaps in foaming properties and lather generation, especially in cold water, and are milder to the hands. Yet, such soaps, despite being made entirely from topped, distilled coco fatty acid, are desirably plastic, which improves ease of manufacture and inhibits development of brittleness and any accompanying tendency of soap bars made to crack during drying after use. The invented soaps are milder than the "control" soaps, made from mixtures of coconut oil with tallow or palm kernel oil, which may be due in part to an appreciably lower pH. Despite not containing as much of longer chain higher fatty acid soaps as the "control" bars, the invented bars were considered by an evaluation panel not to slough significantly more than the control bars and not to crack or split any more than the control bars. In overall preference, the evaluation panel rated the experimental bars significantly better (generally more acceptable to the panel members) than the control bars.
Also within the invention are processes for the manufacture of the invented soap bars, which processes include partially saponifying the topped, distilled coco fatty acid, so as to produce a superfatted soap, containing free topped, distilled coco fatty acid, removing water from the partially saponified topped, distilled, coco fatty acid, mixing the superfatted soap with adjuvant(s), plodding to bar form, cutting the bar to lengths and pressing individual lengths to final bar or cake form. In the manufacture of the superfatted, topped, distilled coco fatty acid soap there are preferably employed a Bran and Lubbe proportioning pump, a Waukesha shear pump and a Mazzoni autoclave, which are useful in carrying out a continuous process.
