Case Study

Inhibitory Effect of Fluorescent Brightener 220 on Fungal Growth

Sadeghi, Golnar, et al. Journal of dermatological treatment, 2009, 20(2), 120-123.

Immunosuppressed patients can develop skin diseases from opportunistic fungi like Aspergillus fumigatus in its mycelial form and Candida albicans as a yeast form. The research examined how fluorescent brightener 220 (optical brightener 220, OB-220) impacted fungal growth.
· Evaluation Methods
The study grew isolates on agar plates using OB-220 at dosage levels between 0.06 and 11.68 mg/ml. The agar dilution method allowed researchers to determine minimum inhibitory concentrations for OB-220 alongside ketoconazole and fluconazole. The effects of OB-220 treatment on hyphae and yeasts were investigated through fluorescence and transmission electron microscopy compared to control samples. Researchers also performed a toxicity assessment of OB-220 against cells.
· Evaluation Results
OB-220 showed minimal inhibitory concentrations at 1.17-1.46 mg/ml against A. fumigatus and 0.58-1.17 mg/ml against C. albicans with only 0.29 mg/ml needed to inhibit Trichophyton tonsurans. OB-220 treatment resulted in cell wall thickening and blurring of the contours as shown by electron microscopy. OB-220 preserved mammalian cell viability at all tested concentrations up to 11.68 mg/ml. The OB-220 compound disrupted standard chitin formation to prevent fungal growth.

Fluorescent Brightener 220 as an "Anti-Counterfeiting Tag" Additive for Inkjet Printing

E.K. Karanikas, et al. Progress in Organic Coatings, 2012, 75(1-2), 1-7.

Two sulfonated stilbene derivatives, Fluorescent Brightener 220 (FBA 220) and Fluorescent Brightener 113 (FBA 113), were added to water-based dispersed inkjet inks in different amounts as anti-counterfeiting tags to prepare digital printing inks with excellent stability. These inks can be used for inkjet printing of polyester and polyamide samples.
Ink Formulation and Evaluation
· Table 1 presents water-based ink formulations that comprise 2% (w/v) dye, 70% (v/v) water, a solvent mixture of 20% 2-propanol (IPA) and 5% ethylene glycol (EG) (v/v), 5% (w/v) dispersing agent, and varying percentages of two active agents. Reference formulations lacking the active agents are also included. The components were homogenized for 10 minutes at room temperature using a homogenizer.
· The prepared ink formulations were tested for surface tension, pH, viscosity, and conductivity across 90 days to evaluate ink stability and anti-counterfeiting agent compatibility with other ink components. The findings indicate that the two fluorescent agents can serve as markers in printing pastes to distinguish authentic products from counterfeit ones.
