Abstract
According to the invention, the compositions and methods provide for the complete removal of synthetic glues or adhesives from a plurality of surfaces through the use of amide solvents in combination with surfactants, chelants, acidulants and/or additional bottle wash additives. Beneficially, the compositions and methods are suitable for use at lower temperatures, including below 35° C., and lower pH conditions, including from 5 to 10, from 6 to 9, and from 6 to 8, in comparison to conventional caustic-based adhesive removal compositions.
