Abstract: A self-assembled active agent may be formed by a process including covalently bonding at least a first component molecule and a second component molecule, the two component molecules displaying synergy such that the effective amount of the self-assembled active agent is lower than the sum of the effective amounts of the first component molecule and the second component molecule. The component molecules may be chosen such that the covalent bonding is reversible, for example through a hydrazone bond between an amine and an aldehyde. The active agent may thus have controllable activity such as an antimicrobial agent, a biocide, an antiviral agent, a preservative, an antifouling agent, a disinfectant, or a sensor agent, such as for a particular molecule or for pH.

Abstract: A cleaning composition according to one embodiment includes a surfactant system comprising a nonionic surfactant in combination with an anionic surfactant; and an amine neutralized organic acid (ANOA). A concentrated composition according to yet another embodiment includes an amine neutralized organic acid (ANOA) present in an effective amount to lower a freezing point of the concentrated composition, wherein the ANOA is present at no more than about 5 wt % based on a total weight of the concentrated composition. A concentrated cleaning composition in yet another embodiment includes a surfactant system having an invert structure, the surfactant system comprising a nonionic surfactant in combination with an anionic surfactant; an organic acid present in a concentration of greater than 0 to about 5 wt % based on a total weight of the cleaning composition; and an alkaline component. Methods of making are also disclosed.
