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 : |
Synthetically produced biocides are effective and widely used in low-pH, rinse-off household and personal care applications to preserve products. Isothiazolinones, such as benzisothiazolinone (BIT) and methylisothiazolinone (MIT), are an important biocide family, commonly used as a preservative in in-can, wash-off household and personal care applications. But growing concerns over the years about their safety, particularly in fabric conditioning and cosmetic applications where allergenic chemicals stay in contact with people’s skin for prolonged periods of time, has led to tighter regulatory restriction on their use. New attitudes towards chemicals has also sparked consumer demand for more sustainable, eco-friendly products. This has placed pressure on formulators to find safer and more sustainable biocide alternatives. |

- The formulation challenge
- Lactic acid : a safe, yet powerful alternative
- Meeting regulatory and consumer demands
- The future of preservation
- Fig. 1 : Preservation mechanism: glycolysis block. Here, lactic acid inhibits sugar fermentation to lactate, preventing bacterial growth
- Fig. 2 : Preservation mechanism: proton shuttle. Lactic acid increases the H+ concentration inside the cell. If H+ supply exceeds energy supply, the bacteria cannot grow
- Table 1 : Lactic acid provides sufficient preservation against fungi – demonstrating a higher log reduction in fungi after 24 hrs and 7 days compared to 15 ppm BIT and MIT |
