Biodegradability

Biodegradability refers to the capacity of a chemical substance or material to be broken down into simpler, harmless compounds by the action of living microorganisms—primarily bacteria, fungi, and enzymes—under natural environmental conditions. In technical terms, it measures the degree to which a substance can be decomposed by microbiological activity within a specific timeframe, typically 28 days under standardized laboratory conditions as defined by OECD 301 test methods. A substance is generally considered readily biodegradable when at least 60% of its theoretical oxygen demand is satisfied within this period, ensuring minimal environmental persistence and bioaccumulation risk.

In industrial cleaning and hygiene applications, biodegradability is a critical parameter for formulating responsible chemical products, particularly across the sectors served by professional cleaning manufacturers. For laundry operations—whether industrial facilities or self-service laundromats—surfactants and detergent builders must biodegrade efficiently to prevent water treatment complications and environmental discharge issues. In the food industry, where cleaning protocols demand powerful degreasing and sanitization without residual chemical contamination, biodegradable formulations ensure compliance with strict sanitary regulations while protecting aquatic ecosystems from wastewater streams. Within HORECA establishments, hotels and restaurants increasingly demand cleaning products that meet biodegradability standards to align with sustainability certifications and guest expectations. Similarly, the livestock sector relies on biodegradable disinfectants and cleaning agents that break down safely in manure management systems and agricultural water runoff.

Regulation (EC) No 648/2004 on detergents requires the surfactants used in detergents to meet ultimate aerobic biodegradability criteria, assessed with standardised test methods such as EN ISO 14593. The EU Ecolabel sets additional, more restrictive criteria on biodegradability and aquatic toxicity. Some Instaquim products for self-service laundries and HORECA carry the EU Ecolabel, such as Eco Wash and Eco Soft.

The choice of readily biodegradable ingredients—such as linear alkylbenzene sulfonates (LAS) and secondary alcohol ethoxylates—enables manufacturers to deliver high-performance cleaning solutions while minimizing environmental burden. Biodegradability testing, conducted through standardized OECD methods, validates product environmental credentials and facilitates transparent communication with industrial clients regarding their sustainability footprint.
