Abstract (en)

The method comprises microencapsulation of an active ingredient in microcapsules and putting in contact said ingredient with the clothes including microcapsules in the washing water when washing and delivering the active ingredient through the wall of the microcapsules providing a gradual release of active ingredient particles as a result of the rupture of rubbed microcapsules while the clothes are being used wherein succinic acid is blended with the microcapsules to adhere them to the clothes, then the clothes with microcapsules are submitted to a thermal treatment. A composition is obtained by blending together microencapsulated active ingredient and succinic acid as a binder agent.
