ABSTRACT:
A tampon applicator which is biodegradable and water-dispersible is provided. The applicator is formed by injection molding a modified poly(vinyl alcohol) which is self-plasticizing. In certain preferred embodiments, the modified poly(vinyl alcohol has the following structure: ##STR1## in which R is hydrogen or methyl, n is a number from 1-1,000, x is 50-99.9 mole percent, y is 0-50 mole percent, and z is 0.001-50 mole percent. Tampon applicators made from this material have been found to be rapidly dispersible in water, to support heavy fungal growth, and to have a commercially acceptable outer surface, i.e., a surface which is not sticky, slippery, or slimy prior to contact of the applicator with water.
