New Method Of Evaluating Quality Characteristics Of Foam In Detergents

Abstract

Foam formation and foam stability are currently used as standard indicators for determining the quality of cosmetic hygienic cleaning agents and detergents. The indicators determine the limit values below which a product will not be considered standard in terms of foaming capacity and cleaning ability. These indicators do not characterize the foam quality which is an important consumer characteristic of foam cleaning agents. The existing methods are analyzed and their drawbacks revealed. A new method of evaluating the quality characteristics of foam is developed. It is proposed to construct a special device for determining the volume weight of foam in a wide range of temperatures to increase the reproducibility and accuracy of the value being determined (foam volume weight). The new method considers all of the drawbacks of the existing techniques.
