The quaternary ammonium salts are well known disinfectants used in hospitals for cleaning of infected surfaces, washing etc. and also in paper manufactories for protecting of paper againts fungal attack. The USSR authors recommend to use these compounds for disinfection of panel and mural paintings. Sterinol is the Polish POLFA product containing the 10% water solution of ammonium dimethyliaurylbenzyl bromide.. In our studies Sterinol was treated as 100% liquied for diluting. The following properties of Sterinol were studied: 1. The concentrations o f Sterinol contained in media for inhibiting the development o f bacteria, their spores and fungi ; 2. The concentrations of Sterinol for disinfecting the mildewed samples of anciend papers in static and dynamic washings (temp. 23° and 55°C); 3. Influence of Sterinol washings on the solubility of inks, China inks and printing paints. The results obtained: 1. Water solutions of Sterinol may be recommended for disinfection of mildewed ancient papers; 2. The highly disinfecting effect against bacteria and fungi show 5,0, 7,5 and 10% solutions at the temperature 50—55°C. In room temperature (20—23°C) 10% Solutions of Sterinol have good disinfecting properties ; 3. Because of its detergent properties Sterinol can be used also for cleaning dirty papers the concentration of 3—5%. 4. Proposed method of disinfection : Prepare the sterilizing washing containing 7,5% of Sterinol (75 ml in 925 ml) of hot water (50—55°C) in suitable beaker and immerse into the paper object. Softened dirt and fungal growth are removed by delicate brushing. After cleaning the paper is placed in fresh solution of Sterinol and left for some minutes. Then it is recommended to rinse the paper in in distiled water to remove the residues of Sterinol. After carefull rinsing the paper must be dried between filter paper sheets. The strongly weakened papers must be cleaned and disinfected by placing then between two nylon nets or on the glass. 5. The above mentioned method may be safely used for printed books and to uncoloured prints. For manuscripts it might be used after establishing the insolubility of inks. 6. Sterinol solutions are also recommended for easy and quick disinfection of laboratory instruments, surface (tables, shelfs) and hands after the work with mildewed objects. This desinfectant is not toxic for men.
