Crodaquat™ TES

The antistatic performance of CRODAQUAT TES has been evaluated by measuring its effectiveness in dissipating applied electrical charges. The faster the charge dissipation – the more effective the antistat.

Test Conditions

Glass and polypropylene tiles were treated with the test formulations indicated below. A charge was applied to the surface and measurements were taken to determine the time needed for the charge to dissipate. The following formulations were evaluated.

Results

Performance on glass was excellent versus the control. While not as impressive as the glass performance, the Crodaquat™ TES system was still many orders of magnitude better than the control on the polypropylene surface.

Crodaquat™ TES is soluble and stable in a wide range of inorganic builders and mineral acids commonly employed in cleaning compounds. This makes Crodaquat™ TES suitable for use in many industrial cleaning applications that would cause problems for other quats.

Quaternary compounds typically form an insoluble complex with common anionic surfactants due to their charge differences. This complex typically posesses cleaning and foaming properties that are inferior to those of the anionic surfactant alone. In addition, the benefits afforded by the quat can be lost in the complex. Worse still, the complex can also lead to instability in the formulation.

Crodaquat™ TES has been shown to have no adverse impact on the foaming properties of the sodium salt of DDBSA – an anionic surfactant commonly used in industrial cleaners. It is thought that this is at least in part due to the decentralized charge of Crodaquat™ TES.

It is often difficult to incorporate nonionic surfactants into heavily built cleaners due to limited solubilities. While formulators often use a hydrotrope such as sodium xylene sulfonate (SXS) to couple the nonionics into solution, this hydrotrope and related sulfonates do little else to benefit the formulation. In fact, the percentage of a formulation that is comprised of hydrotrope can often be signficant thus limiting the amount of detergent actives that can be effectively incorporated into the finished product.

Like the sulfonates, Crodaquat™ TES is very effective in acting as a coupling agent for nonionics. Unlike the sulfonates, Crodaquat™ TES brings other benefits to the formulation such as detergency, and static control. These additional benefits can also be achieved while obtaining the desired coupling at lower use levels. This allows the formulator to incorporate more functional ingredients into the cleaner while getting the desired coupling and the added benefits afforded by Crodaquat™ TES.

Coupling Properties 5% Nonionic Surfactant + 5% Trisodium Phosphate; to 50ºC.
