Abstract

Se valoró el efecto de cinco biocidas naturales obtenidos de las plantas Allium sativum Linn, Eucalyptus citriodora Hook, Pinus caribaea Morelet, Piper auritum H.B.K. y Ricinus communis Linn, sobre la permanencia del papel. Las variables evaluadas fueron reserva alcalina y pH, antes y después de un envejecimiento artificial por calor seco. No se encontraron diferencias estadísticamente significativas al realizar las comparaciones.
