DEQUEST® phosphonates are highly stable organic
chelating and scale control agents which form stable
soluble complexes with metal ions. They prevent
water hardness ions (Ca++ and Mg++) and other
trace metal ions from hindering the efficacy of
cleaning agents. On top of their protecting role,
phosphonates participate to the cleaning process by
loosening and dispersing the dirt. Of special interest
is the capability of phosphonates to prevent scale
deposit while formulated at low level. This ability to

control scale formation at sub-stoichiometric level is
known as threshold scale inhibition.

5 log reductions for the bacteria,
4 log reductions for the yeasts,
3 log reductions for the bacterial spores.
The cleaning and disinfecting process are driven by four
elements: temperature, time, mechanical force and
physicochemistry.
Nowadays, cleaning process is more and more driven by
Ecosavings (energy and water consumption reduction).
Green wave is in the air and focus is placed on maximum
CO2 savings during the process. Accordingly, low energy
cleaning is favored and the physico-chemistry contribution
needs to be increased in order to compensate for the
lower temperature, shorter contact time and reduced
mechanical strength. DEQUEST® products are powerful
ingredients to boost cleaner efficacy and close the gap
arising from these stressed cleaning conditions.
1.1.2 – Formulations Ingredients Key
Requirements.
Formulations ingredients are selected to deliver at the
end of the cleaning process the expected key requirements:
• High cleaning performances: efficient removal of soils
and fats, microbiological control, easy rinse…
• Formulation compatibility: solubility, stability and non
interference with other components
• Improved operations: foam regulation, control of
corrosion, short contact time …
• Cost competitive raw materials: high efficiency at low
dosage
1.1 – Cleaning and Disinfection
• Safe handling and easy application: automated feeding
equipment, minimization of the number of steps…
1.1.1 – Definition
The purpose of the operation is to clean and disinfect
whatever soft or hard surfaces (fabrics, dishes, floors, tiles,
pipes tanks…). On one hand, Cleaning eliminates soils

The industrial bottle washing process is divided in four
steps
• Pre-soak: 30-55° C
• Cleaning and sanitization: 70-95° C, 1.5-2%w NaOH
• Rinse:
• Warm rinse: 60° C
• Cold rinse: 25° C

in the different parts of the washing process. They prevent
scale formation, help the soil removal, keep dirt in
