Abstract

LA INVENCION PROPORCIONA COMPOSICIONES DE PH 1-4 PARA ELIMINAR INCRUSTACIONES CALCAREAS, COMPUESTO DE ACIDO MALEICO, UNA SUSTANCIA ACTIVA NO IONICA, UNA SUSTANCIA ACTIVA ANIONICA, UN PERFUME Y UN ACIDO ALFA-HIDROXI CARBOXILICO (PREFERIBLEMENTE ACIDO CITRICO). SE CREE QUE LA COMBUSTION DEL ACIDO ALFA-HIDROXI CARBOXILICO CON ACIDO MALEICO ES MENOS TOXICA Y MENOS PROPENSA A LA DESCOMPOSICION, QUE UNA CANTIDAD EQUIVALENTE DE ACIDO MALEICO, POR EJEMPLO UNA CANTIDAD LA CUAL PROPORCIONA CARACTERISTICAS COMPARABLES AL ELIMINADOR DE INCRUSTACIONES CALCAREAS. SIN EMBARGO, SE CREE TAMBIEN QUE EL ACIDO ALFA-HIDROXI CARBOXILICO INTERACTUA CON SUSTANCIAS ACTIVAS NO IONICAS PARA DESESTABILIZAR EL PRODUCTO EN AUSENCIA DE LA SUSTANCIA ACTIVA ANIONICA. ASI, HAY LA CREENCIA DE QUE UNA INTERACCION SINERGICA ENTRE LOS COMPONENTES, LOS CUALES PROPORCIONAN UNA ESTABLE Y EFECTIVA COMPOSICION CONTENIENDO EL ACIDO GRASO ALFA-HIDROXI COMO UN SUSTITUTO PARCIAL DEL ACIDO MALEICO.
