Abstract: The present technology relates to antimicrobial cleaning compositions comprising a polyurethane having at least one acid group salted with a biguanide (e.g., bis-biguanide) free base compound. More specifically, the present technology relates to an antimicrobial cleaning composition comprising a) a polyurethane with at least one free acid group salted with a biguanide free base; b) at least one surfactant; and c) a diluent. Surfaces treated with the antimicrobial compositions of the disclosed technology are provided with residual inhibition against the proliferation of microbe growth.

Abstract: Improved aqueous herbicidal gel compositions comprising at least one water-soluble herbicide and a gel forming agent are provided. The gel compositions are particularly useful in increasing the loading of the water-soluble agrochemical salt, maximizing agrochemical uptake and/or translocation into treated plants and minimizing agrochemical loss to the environment. Methods for confined application of the gel compositions to control the growth of unwanted plants are also disclosed.
