A germicidal composition suitable for cleaning fruits, vegetables, skin and hair, includes a mixture of fruit acids and a surfactant. The surfactant may be an anionic surfactant (such as sodium lauryl sulfate), a sophorose lipid biosurfactant, or a combination of the two surfactants. The mixture of fruit acids may include citric acid, glycollic acid, lactic acid, malic acid and tartaric acid. The fruit acids are preferably present, in an aqueous solution, in a sufficient amount to produce a pH of about 2-6, for example 3.8-4.2. The compositions of the present invention are germicidal, and are sufficient to kill 100 % of E. coli, Salmonella and Shigella in 30 seconds after application to the surface of the object.

L'invention a trait à une composition germicide se prêtant au nettoyage de fruits, de légumes, ainsi que de la peau et de la chevelure, laquelle composition est constituée d'un mélange d'agents acidifiants et d'un agent tensioactif. Ce dernier peut être un tensioactif non ionique (un laurylsulfate de sodium, par exemple), un tensioactif biologique de lipide de sophorose ou une combinaison des deux. Le mélange d'agents acidifiants peut comporter de l'acide citrique, de l'acide glycolique, de l'acide lactique, de l'acide malique et de l'acide tartrique. Ces agents acidifiants sont présents, de préférence, en solution aqueuse, sous des quantités suffisantes pour donner un pH compris entre environ 2 et 6, entre 3,8 et 4,2 par exemple. Ces compositions qui sont germicides, suffisent à tuer la totalité d'E. coli, de Salmonella et de Shigella se trouvant sur un objet et ce, en 30 secondes après application à la surface dudit objet.
