ABSTRACT:
There is provided a water dissolvable tampon applicator comprising a first polyvinyl alcohol, a second polyvinyl alcohol having a lower percent hydrolysis than said first polyvinyl alcohol, a plasticizer. Preferably, the first polyvinyl alcohol is polyvinyl alcohol 98% hydrolyzed ultra low viscosity, the second polyvinyl alcohol is polyvinyl alcohol 88% hydrolyzed ultra low viscosity, and the third polyvinyl alcohol is polyvinyl alcohol 88% hydrolyzed low viscosity. The applicator also includes a plasticizer and an antioxidant. The applicator further includes a water insoluble coating that holds moisture. The water insoluble coating is preferably a vinylidene chloride copolymer, and can be used on any polyvinyl alcohol tampon applicator. In another preferred embodiment, the applicator is exposed to humidity prior to application of the coating.
