Detergent enzymes allergy
Respiratory allergy to enzymes used in detergents.
About detergent enzymes allergy
Detergent enzymes such as proteases, amylases and lipases are used in washing powders, cleaning products and various manufacturing processes to break down stains and other materials. They are proteins and therefore high-molecular-weight allergens capable of provoking an IgE-mediated (antibody-driven) allergic response. When enzyme dust or aerosols are inhaled at work, repeated exposure can sensitise the airways, leading to occupational asthma and rhinitis. Workers in detergent production, enzyme manufacture and some food and biotech industries are most at risk, particularly where dust escapes into the air.
Sensitisation develops over time, and once someone reacts, symptoms can come on within minutes to hours of exposure. These include sneezing, a blocked or runny nose, itchy watering eyes, cough, chest tightness and wheeze. Some workers also develop skin reactions. A characteristic feature is that breathing and nasal symptoms often improve on evenings, weekends and holidays and worsen again back at work, which points strongly towards a workplace cause.
Diagnosis is usually coordinated through occupational health and may involve skin-prick testing or specific-IgE blood tests, along with lung-function measurements taken at and away from work. The priority is controlling exposure through enclosed processes, dust suppression such as encapsulated (granulated) enzymes, effective ventilation and, where needed, respiratory protection and health surveillance. Confirmed occupational asthma is reportable under RIDDOR. Because ongoing exposure after sensitisation can cause lasting lung damage, early recognition and removal from further exposure are important.
Common triggers
- Detergent enzymes and products containing it
Symptoms
- Skin rash or dermatitis on exposed areas
- Sneezing, runny nose or watery eyes
- Coughing, wheezing or chest tightness
- Occupational asthma over time
Avoidance & management
- Use recommended protective equipment and ventilation
- Follow workplace exposure controls
- Wash exposed skin promptly
- Report symptoms to occupational health
- Discuss adjustments or alternatives with your employer

Allergy safety: what everyone should know
Mild-to-moderate reaction signs
- Itching, hives or a raised rash
- Swelling of lips, face or eyes
- Tingling mouth, sneezing, runny nose
- Stomach pain, nausea or vomiting
Anaphylaxis — call 999 (UK) or 112 (EU) immediately
- Difficult or noisy breathing, wheeze, persistent cough
- Swelling of the tongue or tightness in the throat
- Dizziness, collapse, pale and floppy (young children)
- Use an adrenaline auto-injector (e.g. EpiPen) at once if prescribed, then call an ambulance even if symptoms improve
Allergy or intolerance? A true allergy involves the immune system and can escalate quickly; an intolerance (e.g. lactose intolerance) is unpleasant but not life-threatening. The symptoms overlap, so self-diagnosis is unreliable.
Getting tested: home-testing kits based on IgG are not diagnostically valid. If you suspect an allergy, ask a GP for referral to an allergy clinic for skin-prick or specific-IgE testing and a supervised food challenge where appropriate.
