    摘要: A water soluble polyvinyl alcohol copolymer having a diad syndiotacticity of greater than about 60% and less than about 70%. In some embodiments, the water soluble polyvinyl alcohol copolymer is soluble in water at a concentration of at least 1 wt% at a temperature of less than 100°C. In other embodiments, the composition is soluble in water at a concentration of at least 5 wt% at a temperature in the range from about 90°C to less than 100°C. The high solubility of the high syndiotactic poly vinyl alcohols disclosed herein may provide various advantages as described herein, including ease of processing and decreased use of harmful solvents.

    摘要: Epilatory compositions may be formed from: 40 to 80 wt% water; 5 to 30 wt% of a mixture of at least one polyvinyl alcohol and at least one polyvinyl alcohol copolymer; 1 to 15 wt% plasticizer, where the plasticizer is a linear or branched composition having from 3 to 15 wt% OH; and up to 40 wt% of one or more additives. Pore strip, keratonic plug removal, and other cosmetic applications may be formed from a similar composition, where the plasticizer is a linear, cyclic, or branched composition having greater than 25 wt% OH; and up to 40 wt% of one or more additives. The adhesive properties of the formulations may be tailored, where a low OH content may result in increased adhesion relative to plasticizers having a high OH content.

    摘要: 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.
