The present invention provides a sustained release composition having hyperbranched polymers that are polyesters that are biobased and biodegradable, and that have at least one active ingredient, which composition delivers the active ingredient over time. These active ingredients can be a wide variety of compounds so long as they can covalently bind to the polymer or be encapsulated in the polymer in a manner that is released at the point of delivery, usually by acid hydrolysis or enzymatic bond scission.
