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 : |
The objective of the present study was to evaluate selected properties of leather samples treated with innovative lactic acid-based agents, applied during the soaking process. The quality of leathers soaked in the baths containing agents based on the organic lactic acid was compared to the products obtained by traditional tanning, in which surfactants were used during the leather soaking process. The obtained results showed that the hides soaked using the eco-compound met the same quality requirements as those soaked in traditional surfactants. The study has proven that the surfactants, which are universally applied during the traditional leather tanning technology, can be replaced with an environmentally friendly agent which effectively reduces effluent pollution as well as its quantity. The proposed method has been successfully tested by one of the largest tanneries in Poland and is in the process of implementation, thus becoming an ecotechnology. |
