Definitions
- the polymers can be used in acid form or in the form of metal salts chosen from the elements of columns (Ib), (IIb), (IIIa), (IIIb), (IVa), (IVb), (Va), (Vb ), (VIb), (VIIb), (VIII) or organic ammonium or phosphonium salts. More specifically, in the field of antibacterials and catalysis, the subject of the present invention is new polymers obtained from commercially available polymers as well as the formulations containing them.
- antibacterials there are many antibacterial, antimicrobial, antifungal and antiviral substances presented in the form of a solution or suspension. This is the case of quaternary ammonium salts used in many fields such as cleaning products, cosmetics.
- quaternary ammonium salts used in many fields such as cleaning products, cosmetics.
- these compounds have several disadvantages.
- the antimicrobial dispersed in the medium ends up in the biotopes and hinders the development of the bacteria or fungi necessary for the biotransformations essential to the living world.
- Antibacterials are also found in wastewater treatment plants where they cause damage to the bacterial flora necessary for the proper functioning of wastewater treatment plants.
- quaternary ammonium salts are not very effective in the presence of organic compounds.
- Quaternary ammonium salts are deactivated by soaps and other anionic detergents, as well as cotton fibers. Also, they should not be used in hard water. Effective levels are estimated at 200 ppm. They degrade at temperatures above 100°C and thus lose all effectiveness. Small molecules like triclosan are widely used in many formulations such as cosmetics, dental hygiene products, gels. Here again, toxic effects have been observed by B. Gaume, N. Bourgougnon, S. Auzoux-Bordenave, B. Roig, B. Le Bot, G. Bedoux* (Comparative Biochemistry and Physiology, Part C, (2012), 156 , 87–94). Small organic molecules have the disadvantage of penetrating very easily through the skin.
