A universal method for determining the detergent effect of surfactants.

Surfactants are indispensable in industrial applications today due to their wetting, emulsifying, dispersing, cleansing, and detergent properties. The use of surfactants extends from the cosmetic industry to the petroleum industry and beyond. Their characteristics and effectiveness can be assessed through various standardized tests, and based on these methods, their applications can be determined.

An improved method for determining the water number for surfactants.

Surfactants have a significant role in everyday life and various industries. Their amphipathic nature significantly influences their properties, functions, and applicability. The ratio of water and oil solubility is characterized by the HLB value (hydrophilic-lipophilic balance) or the closely related water number.
