洗发水用表面活性剂技术发展概况(续完)

Shampoo surfactant technology: consumer benefits, raw materials and recent developments

8广泛使用的辅助表面活性剂椰油酰胺丙基甜菜碱和椰油基甜菜碱是洗发水产品中最常用的两性辅助表面活性剂。椰油酰胺丙基甜菜碱是目前应用最广泛的,其通常以30%水溶液的形式获得[60]。

Surfactants form the core of all shampoo formulations, and contribute to a wide range of different benefits, including cleansing, foaming, rheology control, skin mildness and the deposition of benefit agents to the hair and scalp. The purpose of this review was to assist the design of effective, modern, shampoo surfactant technologies. The mechanisms through which surfactants help deliver their effects are presented, along with the appraisal techniques through which surfactant options can be tested and screened for product development. The steps that should be taken to select the most appropriate blend of surfactants are described, and useful information on the most widely used surfactants is provided. The review concludes with an examination of recent developments in ‘greener’ surfactants,‘sulphate-free’ technologies and structured liquid phases for novel sensory properties and for suspending benefit agents.
