Abstract :
Aim: The purpose of this research work was to study and compare the established physical and chemical characteristics of the developed foam-washing agent with ready-made gels for intimate hygiene produced by manufacturers presented in the Ukrainian market. Materials and Methods: The rheological parameters (structural viscosity, shear stress, and other rheological parameters) were measured using Brookfield DV-II+PRO (USA) viscosimeter, SC 4-21 spindle. Determination of the above parameters was performed using the Ross-Miles Foam Analyzer as a standard device for measuring the foaming ability of soaps and synthetic detergents. The level of the pH value of the foaming test samples was determined by potentiometry method. Results and Discussion: The main groups of components that form part of finished products for intimate hygiene are considered and analyzed. A comparative study of a number of ready-made agents for intimate hygiene and the developed prototype was conducted experimentally. To optimize the physical and chemical characteristics of a modern intimate hygiene product, the following characteristics such as pH value, foaming ability (foam number and foam stability), and structural viscosity were studied. Conclusions: It is proved that the developed agent has satisfactory organoleptic and physical and chemical characteristics. In particular, attention was paid to the structural and mechanical studies that affect the sequence of technological operations, the shelf life of the agent, and consumer characteristics, one of which is the extrusion from a container (flask).
