Abstract
Water soluble films and coatings herein address the problem of water insolubility, color formation, and brittleness upon exposure to oxidizing chemicals, including strong or aggressive oxidizing chemicals. The water soluble films or coatings may include a water soluble polymer and a reactive precursor, such as an alkanolamine or an alkyl alkanolamine. The reactive precursor is water soluble and reactive with oxidizing compounds. Water soluble films or coatings herein may also include a water soluble polymer and an additive mixture including an alkanolamine or an alkyl alkanolamine. The films or coatings, upon exposure to an oxidizing chemical for 8 weeks at 40° C. and ambient humidity, may dissolve fully or achieve 90% dissolution at times of less than 10 minutes. The water soluble films and coatings may advantageously be used with oxidizing chemicals while maintaining water solubility, acceptable color, and flexibility, such as in unit dose packaging, even over extended exposure periods.
