Tanto el grosor como al composici&oacute;n de la capa de cera regulan la absorci&oacute;n de los productos. Las cut&iacute;culas ricas en cera con compuestos no polares, son menos permeables al agua o a los agroqu&iacute;micos de alta polaridad como el glifosato que cut&iacute;culas ricas en cera que presentan una fuerte polaridad. Al igual que la cut&iacute;cula, la membrana celular presenta compuestos con estructuras no polares lo que dificulta la permeabilidad de agroqu&iacute;micos omol&eacute;culas con fuerte polaridad. En general, los aceites paraf&iacute;nicos y aceites vegetales metilados act&uacute;an sobre las estructuras cerosas de la cut&iacute;cula y pared celular promoviendo la penetraci&oacute;n del producto aplicado los aceites son tambi&eacute;n importantes en mantener la solubilidad y la capacidad de penetraci&oacute;n de productos no polares como la atrazina.<\/span><\/p>\r\n\r\n<p style=\"text-align: justify; margin-left: 40px;\"><span style=\"color:#000000\">3.&nbsp; Modifican el estado, estructura o composici&oacute;n de los activos hacia formas que presentan mayor facilidad para ser absorbida y penetrar la cut&iacute;cula, pared celular y membrana celular.

Los compuestos cerosos de la cut&iacute;cula son los componentes m&aacute;s importantes en cuanto a retenci&oacute;n y penetraci&oacute;n concierne. Tanto el grosor como al composici&oacute;n de la capa de cera regulan la absorci&oacute;n de los productos. Las cut&iacute;culas ricas en cera con compuestos no polares, son menos permeables al agua o a los agroqu&iacute;micos de alta polaridad como el glifosato que cut&iacute;culas ricas en cera que presentan una fuerte polaridad. Al igual que la cut&iacute;cula, la membrana celular presenta compuestos con estructuras no polares lo que dificulta la permeabilidad de agroqu&iacute;micos omol&eacute;culas con fuerte polaridad. En general, los aceites paraf&iacute;nicos y aceites vegetales metilados act&uacute;an sobre las estructuras cerosas de la cut&iacute;cula y pared celular promoviendo la penetraci&oacute;n del producto aplicado los aceites son tambi&eacute;n importantes en mantener la solubilidad y la capacidad de penetraci&oacute;n de productos no polares como la atrazina.<\/span><\/p>\r\n\r\n<p style=\"text-align: justify; margin-left: 40px;\"><span style=\"color:#000000\">3.&nbsp; Modifican el estado, estructura o composici&oacute;n de los activos hacia formas que presentan mayor facilidad para ser absorbida y penetrar la cut&iacute;cula, pared celular y membrana celular.
