Detergent enzymes for low-temperature washing instead of phosphates, extra surfactant and hot washing

Replaces: phosphates, part of the surfactant, hot washing · Scope: laundry and dishwashing · Evidence: moderate

The chemical problem#

• Classic detergents relied on phosphate builders (sodium tripolyphosphate) and high temperatures to lift protein, starch and fat stains. Phosphates fed algal blooms; the EU banned them in household laundry detergents (2013) and automatic dishwasher detergents (2017).
• Washing at 60–90 °C uses most of a washing machine’s energy; surfactants — the largest active ingredient — are mostly petrochemical.

Product overview#

Detergent enzymes break stains down catalytically at low temperature: proteases (protein stains), amylases (starch), lipases (fat), mannanases (gums), cellulases (fabric care, anti-greying) and pectate lyases (fruit). A few grams per wash replace temperature and part of the chemical load. Detergent enzymes were Novozymes’ founding mass market and remain a core of Novonesis’ household-care business.

Active ingredient / Composition#

• Enzyme granulates (powders) or stabilised liquid enzyme concentrates, typically 0.5–2 % of a detergent formulation, often several enzymes together.
• Produced by fermentation of engineered Bacillus and fungal strains (Novonesis, IFF, AB Enzymes, Chinese and Indian producers).

Key facts#

Advantages#

• Lower temperature, same cleaning: cold and short cycles cut household energy and CO₂.
• Less chemical per wash: supports phosphate-free and lower-surfactant formulations.
• Biodegradable proteins, used at small doses.

Mode of action#

Each enzyme hydrolyses a specific stain polymer (peptide bonds, starch glycosidic bonds, triglyceride esters, mannans) into small soluble fragments that surfactants then rinse away; engineered variants stay active at 20–30 °C and in the presence of bleach and surfactant.

Application#

Limitations#

• Enzymes complement rather than fully replace surfactants and builders; phosphates were replaced mostly by other chemicals (zeolites, citrates, polycarboxylates), with enzymes making cold washing possible.
• Enzyme dust is a respiratory sensitiser in manufacturing (handled by granulation and workplace limits).
• Market-share figures for enzyme inclusion are only available from market-research firms (not counted here).

Evidence of displacement — D2: measurable displacement (minority share)#

Assessment (hand-reviewed): Europe: average wash temperature fell from 48 °C (1997) to 42.4 °C (2020) (A.I.S.E./Amfep), the shift enzymes make possible; a five-enzyme blend offsets a 30–45% surfactant cut (Novonesis, company-reported). Enzyme-inclusion shares exist only from market research (not counted).

Figures found (verified as quoted, but the assessment above explains why they do not count as displacement evidence for this substitution):

• displacement — The EU-25 market share of phosphate-free laundry detergents was 66% as of the 2006 report. (EU-25, 2006; government or intergovernmental: eur-lex.europa.eu)
• displacement — The inclusion of enzymes in global detergent powder SKUs increased from approximately 18% in 2019 to over 31% in 2025. (global, 2019-2025; weak: dataintelo.com)
• displacement — The share of phosphate-containing detergents in Central Western Europe decreased year-on-year by 16%. (Central Western Europe, not specified; weak: slideserve.com)
• performance — The average temperature for washing in Europe in 2020 was 42.4°C. (Europe, 2020; industry association: amfep.org)
