Commercially available demulsifier formulations are typically a mixture of two to four different chemistries, in carrier solvent(s) such as xylene, heavy aromatic naphtha (HAN), Isopropanol, methanol, 2-Ethylhexanol or diesel. Demulsifiers are manufactured by chemical manufacturers including: Arkema; Baker Hughes; BASF; ChampionX; Clariant; Dow ...

NP-40 is an ethoxylated nonylphenol for non-ionic surfactants and can act as emulsifier and demulsifier agent. NP-40 is often used to break open all membranes within a cell, including the nuclear membrane [citation needed]. To break only the cytoplasmic membrane, other detergents such as digitonin can be used.
An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) owing to liquid-liquid phase separation.Emulsions are part of a more general class of two-phase systems of matter called colloids.
Polyelectrolytes are charged polymers capable of stabilizing (or destabilizing) colloidal emulsions through electrostatic interactions. Their effectiveness can be dependent on molecular weight, pH, solvent polarity, ionic strength, and the hydrophilic-lipophilic balance (HLB).
HLB scale showing classification of surfactant function. The hydrophilic–lipophilic balance (HLB) of a surfactant is a measure of its degree of hydrophilicity or lipophilicity, determined by calculating percentages of molecular weights for the hydrophilic and lipophilic portions of the surfactant molecule, as described by Griffin in 1949 [1] [2] and 1954.

Rohm and Haas Corporate Headquarters in Philadelphia, 2007. The company was founded in Esslingen, Germany, by Dr. Otto Röhm and Mr. Otto Haas in 1907. Haas moved to Philadelphia and began the American side of the business on September 1, 1909, from an office on Front Street, while Otto Röhm remained in Germany to run a company that would eventually become Röhm GmbH.
Dosage of defoamer. A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably.
