Zastosowanie hydrofobowego ekstraktu z kwiatu nagietka do wytwarzania płynu do prania ręcznego

Abstract

Liquid laundry detergents are aqueous solutions of surfactants and excipients. Currently, the market is witnessing a rapid development of products used in the washing process. This is mainly due to the constant competition of producers and constant changes in user preferences. Manufacturers, in order to meet the expectations of consumers increasingly introduce products of plant origin, which do not have a negative impact on both the user and the environment. The paper presents the results of research on the use of the marigold flower extract (Calendula officinalis Flower Extract) obtained under the conditions of supercritical carbon dioxide to produce handwashing laundry detergents. The substances included in this plant have a beneficial effect of bactericidal and soothing. The study analysed the impact of the concentration of the extract on the selected physicochemical and usable properties of washing liquids (stability, viscosity, turbidity, washing ability and foaming performance). It was found that with increasing concentration of the extract we can observe a decrease in viscosity and foam-forming ability. Further-more, with increasing extract concentration, growth of turbidity occurs. There was no significant effect of the extract concentrations in hand washing liquid on their detergency.
