“…Currently, the most commonly used are non-ionic surfactants [12][13][14][15]. They are widely used because of their good solubility in water and organic solvents, and for their ability to perfectly clean grease and dirt [12][13][14][15][16][17]. A surfactant is a technologically important substance for many industries.…”

Surfactants are one of the materials recommended for the cleaning of movable cultural properties. These substances are widespread in other fields – medicine, cosmetics, household appliance industry, etc. Quaternary ammonium compounds are particularly prevalent due to their cleansing and disinfectant properties. Initial studies have shown that surfactants, including quaternary ammonium compounds, have a positive effect on preserved/ restored cultural properties. Using relatively low concentrations of aqueous solutions of these substances, it is possible to obtain sufficiently good results to wash out from the restoration of the document or textiles dirt, acidification of the object and colour changes that cause aging and decomposition processes – hydrolysis and oxidation.

“…However, Syperonic N was banned for sale in Europe in the year of 2000 due to its long-term adverse effects in the aquatic environment. 15 Although efforts were made to find substitutes for the Synperonic N in the conservation community regarding its cleaning properties on artificially soiled textiles, 15 there are no publications that deal with finding a substitute in the manufacturing of BMF for ultrasound flow imaging research.…”

It was found that both blood mimics can provide exactly the same images under spectral Doppler ultrasound and colour Doppler ultrasound in terms of their image qualities. The maximum velocities under constant flow were measured by the spectral Doppler ultrasound as 0.4714 ± 0.001 m.s and 0.4644 ± 0.001 m.s for blood-mimicking fluid with Synperonic N and blood-mimicking fluid with Synperonic A7, respectively. Measured velocities using the two different blood-mimicking fluids were statistically different ( < 0.001), but this difference was less than 2%. The Synperonic A7 can be used as a substitute for Synperonic N as a surfactant material in making the blood-mimicking fluid for ultrasound flow imaging research.
