PERFORMANCE-CHARACTERISTICS AND SOLUTION PROPERTIES OF SURFACTANTS IN SHAMPOOS

A brief analysis is made of the main types of surfactants used in shampoos and bubble baths. The requirements of a modern shampoo are discussed as are the means by which these can be achieved by the use of a number of selected additives such as the traditional alkanolamides, and the newer amine oxides, amido amine betaines and alkyl amine betaines. In particular, such aspects as the achievement of viscosity control, foam generation, shelf life stability and safety are examined. The physical chemistry of the behaviour in solution of several selected non‐ionic and amphoteric nitrogen containing surfactants is discussed and how these affect viscosity modification and foam generation. Mention is also made of the chemistry of the new highly concentrated anionic surfactants and the benefits that they give the formulator. Finally, the attributes of imidazoline derived surfactants are outlined with special reference to their mildness and foaming ability.
