The Detergency of Surfactant Mixtures and Bentonites …

Sodium bentonite (a mineral composed mainly of hydrated aluminium silicates) was mixed with the surfactants used in ecological detergents. This product was used with a suitable particle size that, given its large specific surface area, facilitated its deposition on the cotton fabric, producing the desired effect of increasing the softness of the washed fabric. The surfactants used were an anionic surfactant, namely LAS, and two non-ionic surfactants…

Difference Between Anionic Cationic and Nonionic …

26/02/2020· The key difference between anionic cationic and nonionic surfactants is that anionic surfactants contain negatively charged functional groups, and cationic surfactants contain positively charged functional groups, whereas nonionic surfactants have no net electrical charge. Examples for anionic surfactants include the chemical compounds containing sulfonate, phosphate, sulfate and carboxylates. The cationic surfactants …

Mixed Solutions of Anionic and Zwitterionic Surfactant ...

Such properties are the adsorptions of the two surfactants, the surface dilatational elasticity, the occupancy of the Stern layer by bound counterions, the surface electric potential, and so forth. In particular, the addition of a small amount of Betaine to SDS significantly increases the surface elasticity.

What’s are Anionic and Nonionic Surfactants? – Safe ...

Surfactants are used in cleaning products to reduce surface tension, helping to wash away oil and grease. There are four main categories of surfactant, ionic (anionic, cationic, and amphoteric) and nonionic. Anionic are the most widely used and potent, but they are associated with skin irritation. Nonionic are also found in many household products, and their main advantage is to not form ‘soap …

Carbopol® Aqua CC Cationic Compatible Rheology Modifier

Surfactant Compatibility: Carbopol® Aqua CC polymer is compatible with anionic, non-ionic, amphoteric and cationic surfactants. Recommended Surfactant Active Use Levels: 8.0-22.0% active (surfactant mixtures) or as needed for desired levels of foaming, viscosity, and clarity. Other Compatibility: Carbopol® Aqua CC polymer is compatible

Surfactants Explained. Anionic vs. Non-Ionic vs. Cationic ...

Which surfactant should you use? A combination of two or more types of surfactant are usually used in one formulation because they have different properties. For instance, an anionic surfactant is an effective foam booster but it will tend to irritate skin. To counteract this an amphoteric surfactant is needed. To increase the conditioning property of a shampoo, a cationic surfactant is added. If you go …

Anionic and Cationic Water Based Emulsions - Gellner ...

When an Anionic emulsion is mixed with a Cationic emulsion a strong bond develops and the result is the changing of the substance to a solid. This result is not ideal to be used as a coating because it cannot be applied to substrates. When you apply a Cationic emulsion to an Anionic substrate there is usually better adhesion. Therefore, a Cationic emulsion tends to have better adhesion properties than an Anionic …

Modification of Bentonite with Cationic and Nonionic ...

17/11/2019· Modification of bentonite with a nonionic surfactant did not cause an expansion of the interlayer space of smectite, regardless of the presence of a cationic surfactant. The modification process was found to significantly decrease the specific surface area of bentonite. Improvement of hydrophobic properties and thermal stability was also observed.

The optimum conditions for Cd 2+ removal using surfactant-modified alumina (SMA) are pH 6, contact time 120 min, and ionic strength 0.1 mM NaCl. Under optimum conditions, the removal efficiency of Cd 2+ using SMA increased significantly. We demonstrate that SMA is a novel adsorbent for removal of Cd 2+ from aqueous solution. We investigated adsorption of anionic surfactants, sodium dodecyl ...

Understanding Surfactants: A Guide - International ...

Anionic Surfactants. Anionic surfactants have a negative charge on their hydrophilic end. The negative charge helps the surfactant molecules lift and suspend soils in micelles. Because they are able to attack a broad range of soils, anionic surfactants are used frequently in soaps and detergents. Anionic surfactants create a lot of foam when mixed. While anionic surfactants are excellent for ...
