DEQUEST® FSAdditives for NTA and EDTA replacement in Industrial & Institutional Cleaning


2 3

Compared to aminocarboxylate in general

(including NTA1 and EDTA2), DEQUEST® FS exhibit:

• Scale inhibition at threshold level

• Superior dispersion and chelant properties.

• Superior hard surface cleaning and bleach stabili-

zation.

• Better tox properties compared with NTA and EDTA

• Superior Heavy metal (transition metal) complex-

ation

Compared to traditional phosphonates, DEQUEST®

FS provides

• Increased flexibility to tailor properties to formula-

tion needs

• Enhanced calcium tolerance

• Improved threshold scale inhibition at high pH

• Higher solubility in caustic

• Cost efficiency

What are DEQUEST® FS?

DEQUEST® FS are specialty phosphonates solutions

designed for Industrial & Institutional applications

What do DEQUEST® phosphonates?

DEQUEST® FS 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.

Unlike aminocarboxylate and polycarboxylate chelants,

selected phosphonates have the ability to protect bleach

from decomposition by trace metal ions.

Why DEQUEST® FS?

DEQUEST® FS have been selected to steadily answer the

need for a quick solution for the challenging reformulation

work that many I&I product manufacturers have to face in

order to replace NTA.

DEQUEST® FS properties

DEQUEST® FS exhibit, among others, enhanced calcium

tolerance, scale inhibition and bleach stabilization over a

wide pH range.

Three proprietary DEQUEST® FS have been developed to

fit the broad composition range of I&I formulations.

DEQUEST® FS are specialty phosphonates that have been developed to provide best in class ready to use solutions

for I&I products

The DEQUEST® FS series exist out of different products that have been especially designed to fit the broad range of pH

and chemical composition of I&I cleaners.

Detergent for commercial automatic dishwashing

High pH, high temperature and short contact time are the

challenging conditions found in professional dishwashing.

As a consequence, special attention has to be paid to the

scale formation inhibition that is favoured in this harsh

environment.

To answer solubility issue that may be found at high pH

with traditional phosphonates and control the high scale

formation potential under professional dishwashing

operating conditions, DEQUEST® FS 0520 has been

developed.

Bleach stabilization and stain removal (tea, coffee, wine,

grease…) are also provided by DEQUEST® FS 0536

complexation of free and stain entrapped metal ions.

DEQUEST® FS contribute to soil dispersion in order to have

spotless shiny dish.

Red wine removal of a solution of 10% EDTA (top left - 40% active), 10% NTA (bottom left - 40% active) and 2.6% DEQUEST® FS 0536

(right) indicate a better stain removal with DEQUEST® FS 0536 at 1/4 of the EDTA/NTA dosage

Presoak, detergent and rims cleaner in car wash

Beside pH and surfactants, chelants are one of the most

important ingredient of car wash chemistry. While

traditional chelants provide metal sequestration,

DEQUEST® FS help the traffic film removal (presoak and

detergent), grease cleaning (rims cleaner) and disperse

the soil for oustanding results. Additionally, DEQUEST® FS

effectively bind water hardness ions in the rinse stage

to provide a spotless finish. DEQUEST® FS 0520 is

suitable for concentrated high pH formulations while

DEQUEST® FS 0536 provides a cost effective approach.

DEQUEST® FS 0536 2.6%

Water NTA 10%

Hard water spots removal from metalliced paint (car body piece) demonstrates superiority of DEQUEST® FS 0536 over NTA (40 % active NTA).

Hard surface and in-place cleaners

Hard surface and in-place cleaners cover a wide range of

applications and corresponding operating conditions. The

selected DEQUEST® FS are suitable to cover the full range

of operating conditions and contribute significantly to the

cleaning power of these formulations while protecting

bleaching agent, helping the sanitization process and

preventing corrosion of metallic surfaces. The boost in

grease, cooked food and burned soil removal that is

brought by DEQUEST® FS is of special interest for

application such as all purpose and oven cleaners. Finally,

the sequestering properties of DEQUEST® FS help film and

spotting prevention (i.e. for bottle washing).

DEQUEST® FS 0520 is the most appropriate to provide

corrosion inhibition to aluminium and mild steel surfaces

(i.e. tank and pipe) and to be used in high pH conditions.

DEQUEST® FS 0536 is appropriate for oxygen and

hypochlorite containing formulations.

Detergent and alkalinity booster in laundry

Standard wash processes in professional and institutional

laundries rely on bleach, temperature and/or high pH to

get spotless and disinfected linen. DEQUEST® FS grades

help stain removal while preventing fiber and heating

element encrustation and early bleach decomposition

that may occur in such conditions. DEQUEST® FS 0520 is

the most suitable for alkaline detergent and alkalinity

booster. DEQUEST® FS 0531 provides outstanding

encrustation prevention while DEQUEST® FS 0536 exhibits

through the wash oxygen bleach stabilization (i.e. water

peroxide and peracetic acid).

Dequest® FS 0536 2.6% Dequest® FS 0531 9.1%

NTA 10% Dequest® FS 0520 5.4%

Burned grease removal on tile demonstrating superiority of DEQUEST® FS over NTA (40% active NTA) at reduced dosage (cleaning solution containing 2 % MEA, 2 % non ionic surfactant – pH adjusted to 11).
