The invention discloses a cellulose-based cationized carbon nanofiber / cyclodextrin composite demulsifier. The cellulose-based cationized carbon nanofiber / cyclodextrin composite demulsifier is obtained by sequentially carrying out cyclodextrin modification and cationized modification on cellulose-based carbon nanofibers. The preparation method comprises the following steps: firstly, taking biomass cellulose as a raw material, and sequentially carrying out chemical grafting modification, high-pressure homogenization treatment and hydrothermal reaction to prepare cellulose-based carbon nanofibers; then promoting the reaction between the cellulose-based carbon nanofibers and the natural cyclic oligosaccharide cyclodextrin under an ultrasonic condition, and improving the wettability and interfacial activity of the cellulose-based carbon nanofibers; finally, cyclodextrin is modified by utilizing a cationization reagent, so that the surface of cyclodextrin carries a large amount of positive charges, the interfacial activity of the carbon nanofibers is further enhanced, softening of an interfacial film is promoted, the stability of oil drops is reduced, and the demulsification efficiency is effectively improved. The composite demulsifier has the advantages of being small in dosage, low in demulsification temperature, high in demulsification efficiency, easy to degrade and the like, and the related preparation method is simple, environmentally friendly and suitable for application and popularization.

The present invention consists of the use of cyclic oligosaccharides as modulators of the activity of antiseptic active ingredients, causing a synergistic effect in antimicrobial compositions; more specifically, the present invention presents the ability of cyclic oligosaccharides to alter or modulate the spectrum of antimicrobial activity of an antiseptic active ingredient, enabling efficacy against microorganisms against which the active ingredient is not effective in its isolated form or increasing its efficacy against fungi, resistant microorganisms, such as resistant fungi, and microorganism biofilms. The present invention also presents the novelty of a composition that hinders the development of resistant microorganisms and / or eliminates resistant microorganisms, thanks to the specific characteristic of the cyclic oligosaccharide and the slow and continuous release of the antiseptic active ingredient. For resistant microorganism biofilms, the prolonged antiseptic action obtained has a significant impact on combating the complex defences created by biofilms.
