Surfactants cleaning properties

Ether carboxylates are used not only in powdered detergents but in liquid laundry detergents for their hard water stability, lime soap dispersibility, and electrolyte stability they improve the suspension stability and rheology of the electrolyte builder [130,131]. Formulations based particularly on lauryl ether carboxylate + 4.5 EO combined with fatty acid salt and other anionic surfactants are described [132], sometimes in combination with quaternary compounds as softeners [133,163]. Ether carboxylates show improved cleaning properties as suds-controlling agents in formulations with ethoxylated alkylphenol or fatty alcohol, alkyl phosphate esters or alkoxylate phosphate esters, and water-soluble builders [134]. 

Cationic surfactants produce a positively charged surfactant ion in solution and are mainly quaternary nitrogen compounds such as amines and derivatives and quaternary ammonium salts. Owing to their poor cleaning properties, they are little used as detergents rather their use is a result of their bacteriocidal qualities. Relatively little is known about the mechanisms of biodegradation of these compounds. 

Surfactant Any substance that lowers the surface or interfacial tension of the medium in which it is dissolved. Soaps (fatty acid salts) are surfactants. Detergents are surfactants or surfactant mixtures whose solutions have cleaning properties. 

Surfactant Any substance that lowers the surface or interfacial tension of the medium in which it is dissolved. The substance does not have to be completely soluble and may lower surface or interfadal tension by spreading over the interface. Soaps (fatty acid salts containing at least eight carbon atoms) are surfactants. Detergents are surfactants or surfactant mixtures whose solutions have cleaning properties. Also referred to as surface-active agents or tensides. 

The effect of a sodium silicate on both the cloud point of a solution of a nonionic surfactant (stability of the liquid) and on its ability to solubilize heptane (cleaning property) is discussed in an article by Saito and Shinoda (12). This again illustrates that silicates in a final detergent formula have complex interactions which must be considered in view of the desired properties of the overall formulation. 

Low-foaming surfactant with good cleaning properties for household and industrial cleaners. 

Figure 11.18 illustrates the excellent hard surface cleaning properties of biosurfactants as compared to two commonly used surfactants LES and APG650. Especially sophorolipids ( Sopholiance ) are highly effective and certainly in concenttated applications (1/10, or 0.5%, of active substance). In very diluted applications (1/1000, or 0.005%, of active substance) the difference between surfactants levels out, contrary to... 

The low-fouling property of membranes is evaluated with a nonionic surfactant aqueous solution. Test result shows that, in operation, low-fouling RO membrane has a relatively small permeability declaration ratio of 27%, compared with initial pure water permeability and shows stable operation. On the other hand, conventional fully aromatic polyamide membranes, SU-700 and SUL-G, show 36-47% declaration ratio, even if they show stable operation. And concerning the chemical cleaning properties, low-fouling RO membrane shows better recovery of permeability after chemical cleaning.
