Allergic preservatives found in 60% of dishwasher detergents

Allergic preservatives found in 60% of dishwasher detergents

by Kari Fairweather March 15, 2018


Consumer Council has tested 35 dishwasher detergents (also known as dishwashing liquid) - 60% of the samples (i.e. 21 dishwasher detergents) are detected to contain allergic preservatives (MIT, CMIT, BIT). Some of those are even labelled as "soft on hands", "natural" or "hand moisturising". Repeated use of the detergents containing high amounts of allergy-causing preservatives may cause allergic reaction or even dermatitis.


Here's the list of 21 dishwasher detergents that have allergic preservatives:

  • Seventh Generation Natural Dish Liquid
  • Essential Waitrose Washing Up Liquid Original
  • Clorox Green Works Naturally Derived Dishwashing Liquid - Original Fresh
  • Tesco Lemon Washing Up Liquid
  • LibY Dishwashing Liquid
  • Fairy Original Dishwashing Liquid
  • AXE Skin Moisturizing Dishwashing Detergent with Lemon
  • EZ Clean Dishwashing Detergent Lemon
  • Pengu Dishwashing Detergent with Lemon
  • Labour Lemon Liquid Detergent 
  • Wonderful Dishwashing Liquid with Lemon
  • Castle Lemon Dishwashing Detergent
  • No Frills Dishwashing Detergent with Lemon
  • Earth Choice Dishwash Liquid - Aloe Fresh
  • Daiso Orange Wash Dish Detergent
  • Amway Home Concentrated Dishwashing Liquid
  • Earth Choice Dish Wash Concentrate - Blood Orange & Pomegranate
  • Lion Magica Super Concentrated Dishwashing Detergent (Herbal Green)
  • Lion Charmy V Concentrated Dishwashing Detergent
  • AXE Supra Dishwashing Detergent
  • Swashes Natural-formula Disinfectant Washing detergent

When it comes to choosing and using detergents, Consumer Council advises the below:
  • "study the products’ ingredient lists in detail to detect whether or not they may contain allergic ingredients;
  • people with sensitive skin or suffering from eczema or when they have open wounds on their hands, should avoid using products containing MIT, CMIT or BIT preservatives; 
  • if necessary wear gloves to wash dishes to minimise contact with irritant or allergic substances; 
  • when cleaning dishes, if the dirt is not particularly difficult to remove, use cold water and appropriate amount of detergent, avoid keeping tap water running;
  • in removing difficult grease or stains, soak the dishes in hot water first before cleaning them with detergent to save on consumption of the detergent."
