Dishwasher and laundry detergent danger

How to keep your child safe from detergent poisoning.

Last updated: 16 April 2020

Keeping kids safe is a priority for parents, but it can be easy to overlook the dangers of everyday household products such as kitchen and laundry powders, liquids, pods and capsules.

According to the Raising Children Network:

  • about 50 children are admitted to hospital each week because of poisoning
  • two in three childhood poisonings are associated with medicines
  • household chemicals, including detergents, are another main cause.

If your child has been exposed to household chemicals or other poisons, immediately contact the Poisons Information Centre on 13 11 26.

Poisonings generally occur when a container isn't properly closed or put away out of reach in a cupboard, and – more commonly – if a product doesn't come in a child-resistant container (such as dishwasher detergent in a simple cardboard box).

Detergents are just one source of household danger for children. Have a look at our advice on other home dangers and how to avoid them.

Dishwasher detergent

As a liquid or powder, dishwasher detergent is alkaline and if swallowed in even small amounts it can be extremely caustic and cause severe burns to the mouth, throat and airways. 

In a worst-case scenario, this can lead to lifelong injuries or death.

The brightly coloured packaging, vibrant liquids and lolly-like tablets can look like yummy treats to small kids, and the number of child poisonings associated with dishwasher detergent runs into the hundreds.

Laundry powder, liquids and capsules 

As well as liquids and loose powders, powder blocks and laundry capsules are a potential danger to children. 

The speckled blocks look like bite-sized lumps of sherbet and the capsules can easily be mistaken for jellies. 

These capsules, also known as pods, are designed to dissolve in about 10 seconds in the washing machine, so it doesn't take long for the liquid to leak into little mouths. 

In the 18 months leading up to 2013, there were 85 calls made to Australian poison hotlines relating to accidents involving children and exposure to laundry capsules.

Child-resistant closures (CRCs)

These lids are designed to restrict access to substances that could be dangerous to children. 

They should make it difficult for a youngster to open the container, but not too tricky for an adult to reseal it, otherwise it may not be resealed properly after use. 

As far as dishwasher detergent bottles are concerned, not all their CRCs are designed the same way, and they're generally easier to open than, say, a medicine bottle. 

You generally have to squeeze and turn the cap to open the bottle, but with some, to reseal it you must turn the cap until it clicks into place twice. 

Often bottles don't specify that the cap requires two clicks to be properly closed, so many parents may not be closing the container completely.

While child-resistant closures have reduced the number of child poisonings over the years, the large number of reported incidents involving children and dishwasher detergent shows two things: that people aren't aware of the potential dangers, and that some closures are simply not good enough.

Better labels needed to keep kids safe from poisoning

Many products comply with current labelling laws, but we think the closing mechanism needs to be explained on the bottle (two clicks to secure) and the cautions should stand out more prominently (in red, or in a box) on highly alkaline products.

So don't rely on supposedly child-resistant caps or packaging to keep your children safe: keep potential poisons well out of reach.

Using dishwasher detergent safely

  • Always close the container properly – test that the cap is locked in place
  • Store the detergent out of reach of young children, on a high shelf or in a locked cupboard, and put it back there as soon as you've finished using it
  • Put detergent in the dishwasher just before the wash, and if there's any residue, clean it out afterwards - children have been known to scrape the leftover goop out of the dispenser and eat it
  • Ask grandparents, nannies and others who look after your children to follow your detergent rules - at your home and theirs, if the kids are likely to visit.

Alkaline salts

Products that specify 'alkaline salts' on the label must carry the warning BURNS SKIN AND THROAT when they have a pH of more than 11.5.

Some detergents are based on enzymes and oxygen bleach, which are less alkaline (and therefore less caustic) than the alkaline salts. 

These have a lower pH and are likely to cause less severe injuries when swallowed. 

Enzyme-based products may be less caustic but don't get complacent with them - they can still cause harm and will still have poison warnings on the package.

Signs of poisoning

If you think your child has swallowed a corrosive, burning poison (such as dishwasher detergent, acid, caustic oven cleaner, drain cleaner, swimming pool chemicals or some disinfectants), seek urgent medical help. 

Signs to watch for include:

  • red lips,
  • blisters,
  • possible breathlessness and coughing, and
  • swelling inside the mouth and severe pain.

If your child is poisoned:

  • Don't induce vomiting and give them nothing to eat or drink,
  • Rinse as much of the detergent as possible from their mouth and flush their eyes with water for at least 15 minutes, and
  • If your child has been exposed to household chemicals, such as laundry detergent products, immediately contact the Poisons Information Centre on 13 11 26.
  • If you know what they've swallowed, keep the container of the substance to hand to check the contents and strength. The Poisons Information Centre will be able to give you a more accurate analysis with this information.
