  Disclosed are flushable tampon applicators which comprise a combination of thermoplastic materials that readily disintegrate in water such as toilet water for improved disposal and reduced environmetal concerns regarding the destruction of these applicators. The flushable tampon applicators comprise a combination of high molecular weight polyethylene oxides, low molecular weight polyethylene glycols, and biodegradable polymers, wherein this combination of water-dispersible and biodegradable thermoplastic polymers provide flushable tampon applicators that are readily disposed of and that are smooth, soft, flexible, and non-sticky or non-slimy to the touch before and during use.

  本发明公开了一种可冲洗卫生棉条涂抹器，它由热塑性材料组合而成，这些材料在水中（如马桶水）很容易分解，从而改进了处理方法，减少了对这些涂抹器销毁的环境担忧。这种可冲洗卫生棉条涂抹器由高分子量聚乙烯氧化物、低分子量聚乙二醇和可生物降解聚合物组合而成，其中这种可在水中分散和可生物降解的热塑性聚合物组合可提供易于处理的可冲洗卫生棉条涂抹器，而且在使用前和使用过程中手感光滑、柔软、有弹性、不粘或不紧绷。
