Abstract
The physicochemical properties of adjuvants determine their function and impact upon biological activity. Various physicochemical parameters are key to modifying both the pre-retention events and post-retention consequences of adjuvant usage, irrespective of whether the adjuvants are tank-mix additives or built into formulation. This paper discusses the relationship between physicochemical properties of adjuvants and their functions in agrochemical applications. From a more coherent understanding of the parameters involved, it can be shown that there are ways of predicting the required properties of an adjuvant to solve specific problems. The recognition that different problems often require quite different approaches illustrates that universal adjuvant do not exist per se, so it is essential to know each of their features in order to make correct selection of the appropriate adjuvant depending of diagnosed problem.
