Some investigations of suspoemulsions

摘要

Abstract‘Suspoemulsions’ (SE) is the term used to describe combined formulations of solid and liquid active ingredients as dispersed systems. The parameters influencing an SE were investigated with reference to four examples (one solid and three liquid products) in various mixing ratios. Apart from the type and amount of the partners and the energy dissipation density used, the recipe and viscosity particularly had effects on the formation and properties of an SE. The solid particles in the suspension promoted the comminution of the liquid phase. However, they had practically no influence on the flow behaviour in the three degrees of comminution fineness investigated. The causes of the phenomena discovered are discussed. The storage stability of the SE was equal to that of suspension concentrate (SC) formulations. The advantageous effect of the addition of a thickener on storage stability was similar to that in the case of an
