1. Propiedad del producto<\/strong><\/h4>\n

El diaminetetraacetato dis\u00f3dico es un polvo cristalino o granular blanco o blanco lechoso, inodoro e ins\u00edpido. Es soluble en agua pero extremadamente insoluble en etanol. Es un importante agente quelante que puede quelar iones met\u00e1licos en soluciones. Puede evitar la decoloraci\u00f3n, el deterioro y la turbidez causados por los metales y la p\u00e9rdida por oxidaci\u00f3n de la vitamina C, adem\u00e1s de potenciar la propiedad antioxidante de los aceites (los oligoelementos presentes en los aceites, como el hierro y el cobre, favorecen la oxidaci\u00f3n de los aceites).<\/p>\n

3. \u00c1mbito de aplicaci\u00f3n y uso<\/b><\/strong><\/h4>\n

El EDTA dis\u00f3dico sirve como agente quelante vers\u00e1til en aplicaciones alimentarias, farmac\u00e9uticas e industriales. En el procesado de alimentos (E386), previene la oxidaci\u00f3n secuestrando iones met\u00e1licos, manteniendo la estabilidad del color y el sabor en alimentos enlatados, aderezos y bebidas. La industria cosm\u00e9tica lo utiliza para mejorar la eficacia conservante en productos de cuidado personal. Las aplicaciones m\u00e9dicas incluyen propiedades anticoagulantes en tubos de extracci\u00f3n de sangre y terapia de quelaci\u00f3n para el envenenamiento por metales. Los usos industriales abarcan el tratamiento del agua, el procesado textil y la formulaci\u00f3n de detergentes. Es esencial un estricto control de la dosificaci\u00f3n, con niveles de uso t\u00edpicos que oscilan entre 0,01% y 0,1% en funci\u00f3n de los requisitos de la aplicaci\u00f3n.<\/p>\n

4. Embalaje y almacenamiento<\/b><\/strong><\/h4>\n

El producto suele envasarse en bolsas tejidas forradas de polietileno de 25 kg o en bidones de fibra para cantidades industriales, mientras que para cantidades menores se utilizan contenedores sellados de HDPE. El almacenamiento requiere un ambiente fresco y seco, por debajo de 30\u00b0C, con una humedad relativa inferior a 65%. Un sellado adecuado es crucial para evitar la absorci\u00f3n de humedad y el apelmazamiento. El material debe mantenerse alejado de oxidantes fuertes y sales met\u00e1licas para evitar reacciones indeseables. Si se almacena en las condiciones recomendadas, su vida \u00fatil se prolonga hasta 36 meses. Para su manipulaci\u00f3n, se aconseja el uso de equipo de protecci\u00f3n est\u00e1ndar (guantes, gafas) debido a la posible irritaci\u00f3n leve. La clasificaci\u00f3n para el transporte es la siguiente no peligroso<\/p>","protected":false},"excerpt":{"rendered":"
