Development of resource-saving technology for the production of toilet soap base with a periodic indirect method from neutral fats

Abstract

In the course of the work, the technology of obtaining toilet soap with cosmetic properties was improved; samples of soap with the introduction of physiologically functional substances into the composition of the formulation components were experimentally obtained in order to preserve the initial physiologically active properties. The technological process of preparing the basic toilet soap periodically indirect method of neutral fats includes the following stages: caustic saponification of the fat set; grinding soap base; upholding of the soap base; draining the soap base; ennoblement of a soapy glue. Saponification of the main fat raw material is carried out in the soap boiler and can be produced both on the rest of the soap from the previous cooking, and using the pre-refined adhesive residue from the previous brews. Grinding of the soap base is carried out by hot water 80–90 ?, dry table salt or solution of caustic alkali, which are delivered in separate portions at boiling of the mass with a steaming steam, in an amount necessary for mass separation during grinding into the core (toilet base) and saponified adhesive. The sedimentation of the soap base is made after grinding is performed to separate the mass in the grinding process into the core (toilet base) and the sapwood glue. The temperature of the soap mass before settling must be at least 100 °C. The settling time is not less than 24 hours. The preparation of the core is carried out in a soap boiler. Prefabricated soap of toilet soap is heated to a boil with a hot steam. Then produce a high level of sapper adhesive with dry table salt, which is introduced in the amount necessary to separate the mass into a core and a flushing liquor. After each portion of the salt is injected, the soap mass is boiled for 15–20 minutes until completely dissolved and uniformly distributed in the mass. Salting is considered complete if the soap in the cauldron acquires a granular structure and in the sample on the spatula the kernels of the nucleus are clearly visible, between which the flaked lye flows.
