The investigation of the effect of mineral oils which have different specifications on the performance of palm-and tallow-based soap recipes

In this work, three different types of mineral oils, with the same amount (1% as a ratio), have been added to two different soap recipes from animal origin oils and vegetable-derived fatty acids that have the same rate of foaming agent and similar critical specification values. The pH/conductivity, foaming performance, hardness, and pellet tests were applied to the soaps obtained; and the results were analyzed by comparing the effects of different specifications of mineral oil. The result of this study, the effect of the addition of mineral oils on the soap samples were clarified and characterized by advanced research.
