The objectives of this research were to evaluate in vitro effectiveness of the biocide benzalkonium chloride (BAC) and selected essential oils (EOs) as antifungal agents against fungi isolated from cultural heritage.n aqueous solution of the biocide benzalkonium chloride (BAC) (50% (vol/vol)) was obtained from the Institute for Protection of Cultural Monuments in Serbia. Prior to experiment biocide was diluted in sterile distilled water to make a stock solution of final concentration 10% (vol/vol).
Depending on purity, benzalkonium chloride ranges from colourless to a pale yellow (impure). Benzalkonium chloride is readily soluble in ethanol and acetone. Although dissolution in water is slow, aqueous solutions are easier to handle and are preferred.Aqueous solutions should be neutral to slightly alkaline,. Solutions foam when shaken.enzalkonium chloride is readily soluble in ethanol and acetone. Although dissolution in water is slow, aqueous solutions are easier to handle and are preferred.
