Lactique, AcideL'acide lactique est un acide organique qui joue un rôle dans divers processus biochimiques. Un lactate est un sel de cet acide. Contrairement à ce que peut laisser penser son nom, l'acide lactique n'est pas présent uniquement dans le lait, mais également dans le vin, certains fruits et légumes, et dans les muscles.
L'acide lactique est un acide alpha hydroxylé, sa formule chimique est C3H6O3 et sa structure se reflète dans son nom systématique, l'acide 2-hydroxypropanoïque.

| Résumé : |
Sustainability and safety continue to be major focuses in the cleaning industry, including the segment for antimicrobial products. This segment operates in a complex regulatory landscape that can exacerbate the challenge to formulate an efficient, economic and environmentally friendly product. The European Biocidal Products Regulation (BPR) sets rigorous standards regarding active substance approval, product authorisation and efficacy testing. These rules and market restrictions create additional hurdles, but also present opportunities. They stimulate the search for and development of green, safe ingredients to replace more traditional, hazardous biocides.
Produced by naturel fermentation, L(+)-lactic acid is safe to handle and readily biodegradable. This report shows that lactic acid is also an excellent bactericide. Its biocidal performance in combination with surfactants commonly used in cleaners has been tested in accordance with established EN protocols. Some of these surfactants were found to provide an excellent antibacterial synergy with lactic acid. Thus bacterial reduction levels of log 5 can be achieved even under demanding test conditions and using low concentrations of lactic acid. These data underline the potential of lactic acid to offer an efficient alternative to conventional biocides. |
