Introduction
Watch Water® combines valuable chemistry with commitment, innovation and expertise to deliver simple and the most cost-effective water Dosing Chemicals infrastructure solutions to every customers across the globe. Our comprehensive INSTANT Chemicals treats the scaling, corrosion, organic and inorganic deposit formations. We provide the industry with most powerful, certified chemical Dosing Solutions that remove all problems and prevents corrosion and scale that cause a majority of all possible water quality concerns and environmental problems with phosphates, phosphonates, chlorine issues.
Antiscalant is a pretreatment water additive for reverse osmosis system that is highly effective in preventing the membranes from scaling. Before the feed water enters the reverse osmosis membrane, an antiscalant is injected into the water and sent the through the system. The chemicals creates a time delay between the bicarbonate and the calcium magnesium. The delay allows the water to pass through the membrane before any chemical reaction, in which scale can form, occurs.

Applications
Watch INSTANT dosing chemicals are manufactured in our plant in Mannheim, Germany. INSTANT I-SOFT with the addition of highly concentrated scale inhibitors, corrosion inhibitors, dispersants, oxygen scavengers (Volatile and Non-Volatile), biocides (Oxidizing and Non-oxidizing) for any Residential, Industrial or Commercial applications are proven to be the most environmentally friendly and safe products available in Water Treatment industry.
Watch Water® is the only producer of INSTANT complexing Agents. In addition to the INSTANT I-SOFT (complex), we also offer corrosion inhibitors,
BIOXIDE, Oxygen Scavengers, Cleaning Agent
, Descalers and strong Oxidizers – and all of these products are biodegradable! Watch Water® does not supply Phosphates, EDTA, NTA, Phosphonates or Complexing agents which are not Biodegradable. The performance of the INSTANT I-SOFT is much higher and the biggest advantage for customers is not to buy 95 % of expensive water, which involves higher transport costs and handling costs. It solves the problem of storage as well. The excellent ecological properties of the INSTANT I-SOFT have been confirmed by numerous customers worldwide. Watch Water® therefore recommends the INSTANT I-SOFT as replacement for other, less environment friendly complexing agents, such as Phosphates, Phosphonates, Ion-Exchange Cations, Anions and Silicates etc.

QUESTIONS
INSTANT I-SOFT® is a complete range of high-performance powdered dosing chemicals designed for scale prevention, corrosion control, and biofouling inhibition across the entire water cycle — from drinking water to industrial boilers, cooling towers, and membrane systems.
Manufactured by Watch Water® GmbH, Germany, the INSTANT I-SOFT® family replaces traditional ion-exchange softeners, phosphates, phosphonates, EDTA, and NTA — all of which are non-biodegradable and harmful to the environment.
Each I-SOFT formulation is phosphate-free, biodegradable, and NSF/ANSI/CAN 60 certified, ensuring sustainable and safe operation for industrial and potable applications.
Natural water contains dissolved minerals, gases, and salts that lead to:
Scaling: mineral deposits like CaCO₃ or CaSO₄
Corrosion: oxidation of metal surfaces
Biofouling: bacterial growth on wetted surfaces
By maintaining a controlled concentration of I-SOFT in the system, water remains balanced — preventing salt precipitation, corrosion, and microbial growth simultaneously.
✅ 95 % less transport weight (powder instead of water)
✅ 100 % recyclable packaging (no drums or IBCs)
✅ Safe and easy dilution on-site (1 kg → 20 L solution)
✅ Reduced CO₂ emissions and disposal costs
✅ No phosphate or nitrogen compounds
✅ Compatible with Filtersorb®-SP3 and Katalox-Light® systems
✅ Completely biodegradable and low-toxicity
I-SOFT® products solve the three interlinked water problems:
Scaling – precipitation of salts such as calcium carbonate, sulfate, and silica
Corrosion – degradation of metal due to acidic or high-conductivity water
Biofouling – bacterial growth and slime formation on surfaces
Each I-SOFT type is formulated to treat one or more of these challenges under specific water conditions.
