Biocides are active chemical molecules that are used to limit the growth of germs that come into contact with humans or animals. Antibiotic characteristics are active substances of synthetic or natural origin that are used for the eradication of illnesses caused by bacteria. Biocides are used to limit the usage of antibiotics. Biocide preservation applications are at the forefront of the industry, consuming the most specialist biocides in terms of both volume and value. Despite regulatory pressures to reduce the number of biocides used in end products based on their concentrations, blends of carefully selected biocidal active substances in optimal ratios, combined with new technological advancements, can provide improved preservation solutions without the need for cautionary labelling.
