Recubrimiento de Avobenzona con Eudragit

Abstract

Los protectores solares deben dar amplia cobertura para proteger la epidermis de la radiación. Según la OMS la radiación ultravioleta (RUV) ejerce factores de riesgo asociando nueve enfermedades por exposición excesiva y otras tres por baja exposición. Las poblaciones de mayores riesgos se presentan en los niños y adolescentes. Los protectores solares deben ejercer una acción de absorber, reflejar o dispersar la radiación, según la definición de la Resolución MCS 08/11 armonizada en Argentina con la Disp. 0957/2012. La Avobenzona presenta la particularidad de absorber la radiación en el rango de UV-A (320-400 nm), con un máximo de absorción a 360 nm. Debido a su fotoinestabilidad, es que debe protegerse a fin de evitar su degradación. El objetivo del presente trabajo es recubrir a la Avobenzona con excipientes habitualmente utilizados con ese fin en la Industria Farmacéutica. Para ello, se utilizó Eudragit E PO y Eudragit S 100.
