Paint, clear coat, stain, adhesive, or other aqueous formulations that contain at least one [(dimethylamino)alkyl]-imino-dialcohol and a alkyd emulsion, polymer latex or polyurethane dispersion binder. Also disclosed are methods for manufacture and use of these formulations. The [(dimethylamino)alkyl]-imino-dialcohols provide aqueous formulations having low odor and reduced volatile organic compounds (VOC). The [(dimethylamino)alkyl]-imino-dialcohols also aid in dispersing pigment and other solids so less co-dispersant is needed for aqueous paint or coating formulations.

Polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions are useful in dispersing various compounds in a carrier liquid. The polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions employ polymers having both hydrophilic domains and hydrophobic domains so that the compositions can disperse particles such as polymer particles or droplets in a continuous phase as well as provide stable dispersions that have not been provided before. The antimicrobial properties of the compositions provide much-needed capabilities of fighting infectious agents such as bacteria and viruses in a wide spectrum of products such as paint, adhesives, and coatings. Methods of using these compositions as well as methods of making products using the compositions are disclosed.
