SDS for Cleaning Products: Hazards & What to Check

Learn how to review safety data sheets for commercial cleaning products under EU REACH and CLP, identify key chemical hazards, and protect frontline staff.

Commercial and industrial cleaning products are frequently treated as low-risk commodities because of their familiarity. In professional settings, however, janitorial formulations contain concentrated surfactants, strong acids, caustic bases, solvents, and biocidal actives. In the European Union, these mixtures are governed by Regulation (EC) No 1907/2006 (REACH) and Regulation (EC) No 1272/2008 (CLP).

Failing to consult the manufacturer's Safety Data Sheet (SDS) before introducing a cleaning chemical into a facility puts cleaning operatives at risk of severe burns, eye damage, respiratory sensitisation, and toxic gas exposure. Understanding what to look for on an SDS enables employers to conduct valid Chemical Agents Directive (CAD) risk assessments and specify correct control measures.

Key Hazard Classes in Commercial Cleaning Formulations

Cleaning chemicals encompass a broad chemical spectrum. Depending on whether a product is designed to descale, degrease, disinfect, or strip floors, its hazard profile varies significantly.

• Skin Corrosion and Serious Eye Damage (CLP Category 1): Heavy-duty oven cleaners, drain openers, and machine dishwashing detergents routinely contain high concentrations of sodium hydroxide or potassium hydroxide. Acidic descalers often rely on phosphoric, sulfamic, or hydrochloric acid. Exposure can cause irreversible chemical burns to the skin and permanent corneal destruction (H314, H318).
• Respiratory Irritation and Sensitisation: Spray application of degreasers or sanitising agents generates respirable droplets. Certain preservatives (such as isothiazolinones), quaternary ammonium compounds (QACs), and added fragrances are known skin and respiratory sensitisers (H317, H334). Chronic inhalation can trigger work-related asthma.
• Hazardous Decomposition and Incompatibility: Accidental mixing of hypochlorite-based bleaches with acidic toilet cleaners generates toxic chlorine gas ($Cl_2$). Mixing bleach with ammonia-based glass cleaners releases chloramines. Section 10 of the SDS details these dangerous reactions.
• Aquatic Toxicity: Concentrated sanitising agents and biocidal floor cleaners often contain substances classified as Aquatic Acute 1 or Aquatic Chronic 1–3 (H400, H410, H411). Facilities must prevent concentrated wash-down or unneutralised residues from entering local waterways or surface drains.

Critical SDS Sections to Check

When reviewing an SDS for a cleaning formulation under EU CLP rules, safety managers should focus primarily on the following sections:

Section 2: Hazard Identification

This section provides the immediate risk overview. Check the signal word (DANGER denotes severe hazards; WARNING indicates moderate hazards). Examine the hazard pictograms—especially GHS05 (Corrosion) and GHS08 (Health Hazard). Note the hazard statements (H-statements) to understand whether the risk is acute or chronic.

Section 3: Composition and Ingredients

Review the hazardous substances listed. Professional detergents often fall under the EU Detergents Regulation (EC) No 648/2004 alongside CLP. Look for components listed with specific concentration limits or substances flagged as Substances of Very High Concern (SVHC) on the REACH Candidate List.

Section 8: Exposure Controls and Personal Protection

Never rely on vague statements like "wear suitable gloves." Section 8 must specify:

• Occupational Exposure Limit Values (OELVs): Workplace limits for volatile substances (e.g., 2-butoxyethanol or ethanolamine).
• Glove material and thickness: Specifying nitrile, butyl rubber, or neoprene, alongside measured breakthrough times according to EN 374.
• Respiratory protection: Filter type required if local exhaust ventilation is unavailable during aerosol application (e.g., EN 14387 filter type A-P2).
• Eye protection: Safety glasses with side shields versus indirect-vent chemical splash goggles (EN 166).

Section 10: Stability and Reactivity

This section flags chemical incompatibilities. Cleaning staff must be informed of substances that cannot be stored together or mixed in mop buckets, dosing units, or waste containers.

Section 15: Regulatory Information

Verify whether the product complies with the Detergents Regulation (EC) No 648/2004 (which mandates specific ingredient labelling for surfactants and preservation agents) and the Biocidal Products Regulation (EU) No 528/2012 (BPR) if the product makes antimicrobial or disinfectant claims.

Practical SDS Verification Checklist

Before deploying any new cleaning product on site, verify the following points:

• SDS Currency: Is the SDS compiled according to the current Annex II of REACH (Regulation (EU) 2020/878 format), including revision dates and Unique Formula Identifiers (UFI) where required?
• Language: Is the document supplied in the official language of the EU Member State where the product is used and understood by cleaning personnel?
• Dilution vs. Concentrate: Does the SDS provide hazard data for the product as supplied, and are exposure scenarios or safe-use summaries included for the working dilution?
• PPE Availability: Are the exact protective glove types, eye protection, and aprons specified in Section 8 physically stocked and readily available to staff?
• First Aid Access: Does Section 4 indicate specific immediate interventions (e.g., emergency eye-wash stations within 10 seconds of use for Category 1 corrosives)?

Frequently Asked Questions (FAQ)

Do all professional cleaning products require a Safety Data Sheet?

Under REACH Article 31, an SDS is mandatory if a cleaning chemical meets the criteria for classification as hazardous under CLP, or if it contains certain hazardous substances above specified concentration thresholds (even if the mixture itself is not classified as hazardous).

Why are professional cleaning products classified more severely than supermarket cleaners?

Commercial formulations are usually sold in concentrated forms to reduce transport costs and packaging waste. While domestic products are pre-diluted for immediate safe use, industrial concentrates contain higher active concentrations of alkalis, acids, and surfactants, resulting in stricter CLP hazard classifications.

What is a UFI code and where should it appear?

The Unique Formula Identifier (UFI) is a 16-character alphanumeric code required under CLP Annex VIII for hazardous mixtures placed on the EU market. For commercial products, it must appear on the product packaging label and within Section 1.1 of the SDS, linking the formulation directly to Poison Centre databases.

Can cleaning staff mix two products if both are non-corrosive?

No. Chemical compatibility cannot be inferred from the absence of a corrosive pictogram. Neutral or mildly alkaline products may contain complexing agents, oxidisers, or active quaternary ammonium salts that react unexpectedly when blended, generating hazardous vapors or neutralising the required cleaning and disinfecting efficacy.
