Las pruebas de irritaci\u00f3n de la piel y de toxicidad por corrosi\u00f3n son la principal prioridad.<\/span><br><span style=\"color: #000000;\">A menudo se prefiere la prueba de irritaci\u00f3n cut\u00e1nea de la OCDE 439, que se desarroll\u00f3 como una alternativa a los experimentos con animales, debido a su validez cient\u00edfica y al cumplimiento de la normativa

evaluar el potencial de irritaci\u00f3n de la piel de productos qu\u00edmicos y productos. <\/span><span style=\"color: #000000;\">La prueba se realiza utilizando modelos de epidermis humanas reconstituidos (RHE) que imitan la epidermis humana.<\/span><\/p><p><span style=\"color: #000000;\">Este m\u00e9todo ofrece una alternativa confiable, especialmente en \u00e1reas donde las pruebas en
