Abstract: Personal cleansers and surfactant blends useful therein are disclosed. The cleansers comprise a primary anionic surfactant, a saturated C8-C-14 alkyl N,N-dialkylamide, and water. The cleansers have good foaming properties and improved viscosity build profiles compared with cleansers that rely on alkanolamides or betaines as the secondary surfactant. The saturated C8-C14 alkyl N,N-dialkylamides are water-white liquids that solubilize cleanser components well, including high levels of fragrances, and can be formulated easily without heating at any actives level up to 100%. Importantly, the surfactant blends build viscosity with less added salt compared with alkanolamide or betaine-based blends, even with more challenging anionic surfactants. Moisturizing cleansers disclosed herein have excellent flash foaming character, foam volume, and foam feel and provide a luxurious, lotion-like after-feel. The personal cleansers include, among others, shampoos, body washes, facial cleansers, shower gels, liquid soaps, hand soaps, baby liquid cleansers, pet shampoos, and bubble baths. The fatty N,N-dialkylamides are also valuable for formulating oil-in-water emulsions with good stability.

Abstract translation: 公开了可用于其中的个人清洁剂和表面活性剂混合物。 清洁剂包括主阴离子表面活性剂，饱和C 8 -C 14烷基N，N-二烷基酰胺和水。 与依赖于链烷醇酰胺或甜菜碱作为第二表面活性剂的清洁剂相比，清洁剂具有良好的起泡性能和改进的粘度构型。 饱和的C8-C14烷基N，N-二烷基酰胺是水白色液体，可以很好地溶解清洁剂组分，包括高水平的香料，并且可以在任何高达100％的活性水平下轻松配制而不加热配制。 重要的是，即使使用更具挑战性的阴离子表面活性剂，与烷醇酰胺或甜菜碱基混合物相比，表面活性剂共混物的添加盐也较少。 本文公开的保湿清洁剂具有优异的闪光发泡特性，泡沫体积和泡沫感，并提供了豪华的洗剂般的后感。 个人清洁剂包括洗发水，身体洗涤剂，面部清洁剂，沐浴露，液体肥皂，手肥皂，婴儿液体清洁剂，宠物洗发剂和泡泡浴。 脂肪N，N-二烷基酰胺对于配制具有良好稳定性的水包油乳液也是有价值的。
