There is a continuing need for hair care formulas to deliver superior conditioning benefits with highly efficient deposition of hair-enhancing components. In this paper, we describe high-charge-density (3.0 mEq/g) cassia hydroxypropyltrimonium chloride (cassia HPTC), a quaternized galactomannan from the endosperm of Cassia tora and Cassia obtusifolia. Cassia HPTC is shown to participate in the coacervate phase of conditioning shampoos, from which it is deposited onto hair to provide conditioning benefits. Cryo-scanning electron microscopy and time-of-flight secondary ion mass spectrometry were used to observe and characterize the cassia HPTC deposits left on hair. The high-charge-density cassia HPTC resulted in improved deposition efficiency compared with a quaternized guar-containing formula. Cassia HPTC offers benefits as an alternative to traditional cationic polymers as conditioning agents or as an adjunct conditioner to decrease the amount of cationic polymer needed to achieve the desired conditioning performance.
人们一直需要护发配方产品，以便通过高效沉积头发增强成分来提供卓越的调理功效。在本文中，我们描述了高电荷密度（3.0 毫当量/克）的决明子羟丙基三甲基氯化铵（决明子 HPTC），它是一种来自决明子和钝叶决明胚乳的季铵化半乳甘露聚糖。决明子 HPTC 被证明参与调理香波的凝聚相，并从该相中沉积到头发上以提供调理功效。采用低温扫描电子显微镜和飞行时间二次离子质谱法来观察和表征留在头发上的决明子 HPTC 沉积物。与含季铵化瓜尔胶的配方相比，高电荷密度的决明子 HPTC 提高了沉积效率。决明子 HPTC 作为传统阳离子聚合物作为调理剂的替代品，或作为辅助调理剂以减少实现所需调理性能所需的阳离子聚合物用量，具有诸多益处。
