NewsStudy explores how preservatives in cosmetics oppose microbes
A study of preservatives added to cosmetics found that they kill the microorganisms rather than inhibiting their growth. The substances investigated affect various substructures of microbial cells, including the cell wall, cell membrane, enzymes involved in metabolism, protein synthesis systems, and genetic material.
