Los parabenos son conservantes utilizados en una amplia variedad de productos de cuidado personal y alimentos para prevenir el crecimiento de microbios. Estos químicos de alteración endocrina se pueden absorber a través de la piel, la sangre y el sistema digestivo. [1]

ENCONTRADO EN: Champús, acondicionadores, lociones, limpiadores faciales y de ducha y exfoliantes

QUÉ A BUSCAR EN LA ETIQUETA: Etilparabeno, butilparabeno, metilparabeno, propilparabeno, isobutilparabeno, isopropilparabeno, otros ingredientes que terminan en –parabeno

¿QUÉ SON LOS PARABENOS? Los parabenos son en realidad varios productos químicos distintos con una estructura molecular similar. Varios son comunes en una amplia gama de productos cosméticos y de cuidado personal: etilparabeno, butilparabeno, isobutilparabeno, isopropilparabeno, metilparabeno y propilparabeno.MÁS ...

PREOCUPACIONES DE SALUD: Alteración endocrina, cáncer, toxicidad para el desarrollo y la reproducción MÁS ...

POBLACIONES VULNERABLES: Embarazadas y niños pequeños.

REGLAMENTO: Algunas formas de parabenos están prohibidas en Dinamarca (propil y butilparabeno, sus isoformas y sus sales) en productos cosméticos para niños de hasta 3 años. [2]

CÓMO EVITAR: Busque productos etiquetados como "sin parabeno" y lea las listas de ingredientes en las etiquetas para evitar los productos con parabenos. Muchos fabricantes de cosméticos naturales y orgánicos han encontrado alternativas efectivas a los parabenos para prevenir el crecimiento microbiano en productos para el cuidado personal. Algunas compañías han creado productos sin conservantes que tienen una vida útil más corta que los productos convencionales (seis meses a un año).
