Single Dose Disinfectant
Generally, the present disclosure is directed to single dose, or unitary disinfecting concentrates that are stable in a dissolvable container. The disinfecting concentrate includes at least one biodegradable carboxylic acid and at least one anionic surfactant, and is stable for at least one week at 54° C. as measured according to EPA storage stability test protocol (830.6317).
