Abstract:
1. A product system comprising at least one porous carrier, wherein the porous carrier is inorganic, organic, or a combination thereof, at least one active ingredient which is introduced into the porous carrier, and at least one protective substance, wherein at least part of the total amount of the at least one protective substance present in the product system is introduced in the pores of the porous carrier, wherein the at least one protective substance can be deactivated in a targeted manner by one or more of an action of pressure waves on the product system, an action of UV radiation on the product system, increasing temperature of the product system, a pH change, and an action of at least one enzyme on the protective substance, wherein when the porous carrier is in an aqueous medium, the at least one protective substance does not allow any of the at least one active ingredient to be released prior to deactivation of the at least one protective substance, wherein at least 80% by weight of the at least one active ingredient is released within 1 hour when the at least one protective substance is deactivated by an action of pressure waves on the product system, wherein at least 80% by weight of the at least one active ingredient is released within 12 hours when the at least one protective substance is deactivated by an action of UV radiation on the product system, wherein at least 60% by weight of the at least one active ingredient is released within 1 hour when the at least one protective substance is deactivated by increasing temperature of the product system, wherein at least 70% by weight of the at least one active ingredient is released within 8 hours when the at least one protective substance is deactivated by a pH change, wherein at least 80% by weight of the at least one active ingredient is released within 24 hours when the at least one protective substance is deactivated by an action of at least one enzyme on the protective substance, and wherein, detected by investigating the outermost atomic layer of the product system by means of XPS, at least part of the outermost surface of the product system is formed by the porous carrier.
