Abstract

The aim of the research is to develop the composition of solid soaps for the treatment and prevention of exacerbation of psoriasis using a classic recipe based on vegetable oils.

Materials and methods. The studied samples of solid soaps were made based on vegetable oils of domestic and foreign production using an aqueous solution of sodium hydroxide for their saponification. Citric acid (China, p. K707784), salicylic acid (China, p. Y1504007) and lactobionic acid (Poland, p. 20161118) were used as active pharmaceutical ingredients. Organoleptic (appearance, shape, color, smell) and physico-chemical (mass fraction of fatty acids, initial volume of foam, mass fraction of soda products) studies were carried out following DSTU 4537:2006 Solid toilet soap. General technical conditions. Indicators were chosen as standards for soap of the special - therapeutic brand.

Results. Samples containing a combination of coconut, avocado, castor, jojoba and palm oils, as well as a combination of castor, jojoba, macadamia, mango and avocado oils were found to have insufficient foaming capacity. Most samples are not firm enough, especially those containing rosehip oil. The composition of solid soap based on palm kernel oil, coconut oil, avocado oil, castor oil, almond oil, and olive oil, among others, showed the best organoleptic properties. All the studied samples were within the normal range according to the parameters of the mass fraction of soda products and the mass fraction of fatty acids. At the same time, introducing active substances into the composition did not lead to a deterioration of the developed solid soap's normative or controlled organoleptic and physicochemical properties.

Conclusions. The research conducted made it possible to obtain the optimal composition of solid soap, which can be used to prevent psoriasis exacerbation due to the introduction of pomegranate seed oil. Based on this, solid soaps were created for the treatment of psoriasis in the period of exacerbation, one of which includes lactobionic acid and the other – a combination of citric and salicylic acids
