• Ampholyte terpolymers providing superior conditioning properties in shampoos and other hair care products
  申请人：Calgon Corporation

  公开号：EP0521666A1

  公开（公告）日：1993-01-07

  Ampholyte terpolymer conditioning additives for hair care products are disclosed which improve wet and dry hair combability, especially detangling and reduced static flyaway, sheen, and fixative properties, especially curl retention. The ampholyte terpolymers may have a weight average molecular weight of from about 10 thousand to 10 million, and comprise (a) from at least 1 to as much as 95 weight percent of a nonionic monomer, (b) from at least 5 to as much as 80 weight percent of a cationic monomer, and (c) from at least 1 to as much as 75 weight percent of an anionic monomer. In a preferred embodiment, the amount of the cationic and anionic components is such that the overall % net charge of the ampholyte terpolymer is between -5.0 and +5.0. The ampholyte terpolymers are added to hair care product formulations in amounts ranging from 0.1-10% by weight. They are particularly compatible with anionic surfactant shampoos, providing clear formulations without the loss of conditioning properties described above.

  本发明公开了用于护发产品的两性聚醚三元共聚物调理添加剂，可改善头发的干湿梳理性，尤其是顺发和减少静电飞散、光泽和定型特性，特别是卷曲保持力。两性聚醚三元共聚物的重量平均分子量约为 10,000 到 10,000,000 磅，包含 (a) 至少 1%到 95%重量百分比的非离子单体，(b) 至少 5%到 80%重量百分比的阳离子单体，以及 (c) 至少 1%到 75%重量百分比的阴离子单体。在一个优选的实施方案中，阳离子和阴离子组分的用量应使两性三元共聚物的总净电荷百分比介于-5.0 和 +5.0之间。两性聚醚三元共聚物可添加到护发产品配方中，添加量为 0.1-10%（按重量计）。它们与阴离子表面活性剂洗发水的相容性特别好，可以提供清澈的配方，而不会损失上述的调理特性。
