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).
Benzalkonium chloride is a frequently used preservative in eye drops; typical concentrations range from 0.004% to 0.01%. Stronger concentrations can be caustic and cause irreversible damage to the corneal endothelium.enzalkonium chloride is a mainstay of phase-transfer catalysis, an important technology in the synthesis of organic compounds, including drugs.
