Phosphate-free household chemicals: why it matters and how to choose

What we do not see: phosphates and algal blooms

Every third Ukrainian family still washes with powder containing phosphates. After washing, the solution enters the sewage system, and then into the Dnipro, Desna, and Southern Bug rivers. Then a process occurs that ecologists call eutrophication: phosphates feed algae, they multiply massively, absorb oxygen, and the water body gradually "dies". Green duckweed on the surface of the Dnipro in summer, fish suffocation in the Kremenchuk reservoir, unpleasant odor from ponds in parks — these are the direct consequences of phosphates in everyday life.

Europe banned phosphates in washing powders back in 2013. Ukraine is moving along the same path, but more slowly. Meanwhile, the phosphate-free chemicals market is growing by 15–20% annually. For both manufacturers and consumers, this is an issue that can no longer be ignored.

What phosphates are and why they were added to detergents

Phosphates (salts of phosphoric acid) are substances that perform several functions simultaneously in detergents:

• Water softening. Phosphates bind calcium and magnesium ions, making the water "softer" and allowing surfactants to work more efficiently. For regions with hard water (which is most of Ukraine — Odesa, Zaporizhzhia, Kharkiv), this was important.
• Keeping dirt in solution. After separation from the fabric, dirt particles must remain in the water and not settle back. Phosphates ensure this.
• Enhancing surfactant action. Phosphates create an alkaline environment (pH 10–11) where surface-active agents work at maximum capacity.

So phosphates are not an "accidental" component. They genuinely improve washing ability. That is why they were used for decades, starting in the 1950s. But the price of this efficiency turned out to be too high.

Environmental impact: from washing powder to a dead water body

The mechanism of eutrophication

Eutrophication is the excessive enrichment of a water body with nutrients, primarily phosphorus and nitrogen. The process looks like this:

1. Phosphates enter wastewater after washing clothes or dishes.

2. Treatment plants remove only 30–50% of phosphates (even modern ones — no more than 70%).

3. The rest enters rivers and lakes.

4. Phosphorus stimulates massive algal growth (algal bloom).

5. Algae die off, and their decomposition absorbs oxygen.

6. Fish and other organisms die from a lack of oxygen.

One ton of household powder with 15% phosphates introduces 150 kg of phosphate compounds into the water basin. To "trigger" eutrophication in a lake with an area of 1 hectare, 1 kg of phosphorus per year is enough.

The Ukrainian situation

Ukraine is a country with a developed river system: the Dnipro, Dniester, Southern Bug, and Siverskyi Donets — all of them receive industrial and domestic wastewater. According to Держводагентство (State Agency of Water Resources of Ukraine), over 60% of Ukraine's water bodies have an elevated level of eutrophication. The problem is particularly acute in the Kremenchuk, Kaniv, and Kakhovka reservoirs (prior to the dam destruction), where massive water "blooming" was observed every summer.

It is worth noting that household chemicals are not the only source of phosphates. Agricultural fertilizers contribute a significant share. But household chemicals are a source that everyone can control personally.

Regulatory landscape: EU and Ukraine

European experience

The European Union regulates the use of phosphates in household chemicals through Regulation (EU) No 259/2012:

Additionally, Directive 2015/73/EU clarified the requirements for labeling and verification. For Ukrainian manufacturers planning to export to the EU, compliance with these standards is mandatory. More details about the requirements are in the article "Requirements for household chemicals for export to the EU".

Ukraine: current status

In Ukraine, ДСТУ 2972:2020 limits the phosphate content in washing powders to 5% (for comparison: Soviet powders contained 15–30%). This is an intermediate standard. A complete ban for the household segment has not yet been adopted, but a draft Law on restricting phosphates in household chemicals is under consideration. Given Ukraine's course toward European integration, full implementation of EU standards is a matter of time.

For manufacturers, this means: transitioning to phosphate-free formulas should be done now. Those who do it first will gain a competitive advantage in both the domestic and export markets.

Alternatives to phosphates: what modern formulas use

Abandoning phosphates is not just removing one component. It is a complete restructuring of the formula, as phosphates performed several functions. Here are the main substitutes. Definitions of chemical terms are in the industrial chemistry glossary.

Zeolites (Zeolite A, Zeolite P)

Natural or synthetic aluminosilicates. They work as ion exchangers: capturing calcium and magnesium ions from the water, releasing sodium. This is the main substitute for phosphates in washing powders.

Pros: affordable price, lack of toxicity, no impact on water bodies.

Cons: insoluble in water, can leave a white residue on dark fabrics, do not work in liquid detergents.

Silicates (sodium metasilicate, sodium disilicate)

They perform a dual function: softening water and maintaining an alkaline environment for the efficient operation of surfactants. Widely used in powders and tablets for dishwashers.

Pros: good softening ability, anti-corrosion effect, affordable price.

Cons: can irritate the skin upon direct contact, require careful dosing.

Organic chelators: GLDA and MGDA

Glutamic acid diacetic acid (GLDA) and methylglycinediacetic acid (MGDA) are a new generation of phosphate substitutes. They bind hardness ions into stable complexes that do not break down with changes in temperature or pH.

Pros: full biodegradability in 28 days (OECD 301), work in liquid and powder forms, effective across a wide range of temperatures.

Cons: higher cost compared to zeolites and silicates.

Citrates (sodium citrate, citric acid)

A natural component that functions as a water softener and pH regulator. Used primarily in premium segment eco-detergents.

Pros: completely natural, biodegradable, safe for the skin.

Cons: moderate softening ability, requires combination with other components for hard water.

Comparison table of alternatives

In practice, modern phosphate-free formulas combine 2–3 alternatives. For example, zeolite + GLDA in powders or silicate + citrate in liquid detergents. For approaches to eco-labeling such formulas, see the article "Eco-detergents: labeling and certifications".

How to read labels: identifying phosphate-free products

Not all manufacturers honestly indicate "phosphate-free" on the packaging. Here is how to check it yourself:

What to look for in the composition

Contains phosphates (avoid): Sodium Tripolyphosphate (STPP), Tetrapotassium Pyrophosphate (TKPP), Trisodium Phosphate (TSP), any components with "phosphate" in the name.

Phosphate-free markers (good): Zeolite A, Sodium Citrate, GLDA, MGDA, Sodium Disilicate, Sodium Metasilicate.

Labeling and certifications

• EU Ecolabel — guarantees compliance with EU standards regarding phosphates.
• Nordic Swan — a Scandinavian standard, stricter than the EU Ecolabel.
• Ecocert — a French certificate for eco-products.
• The inscription "Без фосфатів" / "Phosphate-free" — must correspond to the actual composition.

If the packaging says "80% phosphate reduction," it means phosphates are still present. A truly phosphate-free product contains 0% phosphates or less than 0.3 g of phosphorus per cycle.

Three myths about phosphate-free chemicals

Myth 1: "Phosphate-free washes worse"

This was partially true in the 1990s when the first phosphate-free formulas were inferior to phosphate ones. The modern situation is different. Research by the University of Leeds (2023) showed that formulas based on GLDA + zeolite demonstrate comparable or better washing ability at temperatures of 30–60 °C. The key difference is not in the presence or absence of phosphates, but in the overall quality of the formula.

Washing problems arise when using cheap phosphate-free powders where phosphates were simply removed without being replaced by adequate alternatives. A quality replacement requires R&D and the correct balance of components.

Myth 2: "Phosphate-free chemicals are significantly more expensive"

The retail price of phosphate-free washing powder in Ukraine is from 120 to 350 UAH per 1 kg (as of 2026). Phosphate analogs are from 80 to 200 UAH. Yes, there is a difference, but it is shrinking every year.

At the same time, phosphate-free detergents are often concentrated: the consumption per wash is lower. If you calculate the cost of one washing cycle, the difference is 1–3 UAH. And for manufacturers exporting to the EU, a phosphate-free formula is the only option, so the issue of price transforms into an issue of market access.

Myth 3: "It is only for eco-activists"

Phosphate-free chemicals are no longer a niche product. In Germany, Austria, and the Scandinavian countries, phosphate washing powders are simply not on sale. In Ukraine, the share of phosphate-free detergents in the laundry category grew from 12% in 2020 to 35% in 2025. According to forecasts, by 2028 it will be 60–70%.

This is not an "eco-trend," but a regulatory reality. Like the transition from leaded to unleaded gasoline, it is a matter of time, not beliefs.

FAQ

Are phosphates really dangerous to human health?

Phosphates in household chemicals do not pose a direct threat to health during normal use. The main problem is environmental: entering water bodies, they cause eutrophication, which destroys aquatic ecosystems. Indirectly, this affects drinking water quality and water supply resources. That is, the harm is systemic, not individual.

How can I check if my washing powder contains phosphates?

Look at the composition on the packaging. Look for Sodium Tripolyphosphate (STPP) — this is the most common phosphate in washing powders. Also, pay attention to Tetrapotassium Pyrophosphate and other compounds with the word "phosphate". If the composition includes Zeolite A, GLDA, or Sodium Citrate, these are signs of a phosphate-free formula.

Are phosphate-free detergents suitable for hard water?

Yes, but the formula must contain effective substitutes for water softening. Zeolites and GLDA work well with hard water. If you live in a region with very hard water (Odesa, Mykolaiv, Zaporizhzhia), choose detergents with a combination of zeolite + GLDA or add a separate softener.

What is the difference between "phosphate-free" and "eco" on the label?

"Phosphate-free" means the absence of phosphate compounds in the composition — this is a specific, measurable parameter. "Eco" is a broader concept that may include the biodegradability of surfactants, the absence of chlorine, natural fragrances, and ecological packaging. A detergent can be phosphate-free but not "eco" (if it contains other harmful components), and vice versa. Look for specific certificates — EU Ecolabel, Ecocert — rather than marketing claims.

SVK: phosphate-free formulas for your brand

As Nela Martakova notes: "When we started developing phosphate-free formulas in 2018, the main challenge was the hard water of the Dnipropetrovsk region — 8–12 mg-eq/l. It took 14 recipe iterations before we found the optimal combination of Zeolite A and GLDA, which works without compromise even at such hardness."

According to Держводагентство України, over 60% of the country's water bodies have an elevated level of eutrophication — and the transition to phosphate-free chemicals is one of the key measures to improve the situation.

SVK has been developing and manufacturing phosphate-free household chemicals since 2018. In our R&D laboratory, there are over 1000 ready-made formulas for Private Label, including:

• Washing powders and gels — based on zeolites and GLDA, effective from 20 °C.
• Dishwasher detergents — phosphate-free tablets and powders that comply with EU 259/2012.
• All-purpose detergents — with biodegradable surfactants and natural chelators.
• Concentrated formulas — lower consumption, less plastic, smaller environmental footprint.

Each formula undergoes testing for washing ability, biodegradability, and dermatological safety. We help partners create a product that meets both Ukrainian and EU standards — so that entry into export markets is unhindered.

The minimum order is from 500 units. From idea to finished product on the shelf — 4–6 weeks. More details about the process of launching a PL brand are in the article "How to create your own household chemicals brand".
