Laundry detergent pods (or packs) are products containing an ultra-concentrated amount of laundry detergent, softener and other soap types enclosed in dissolvable plastic discs. Notable brands of these packs include Arm & Hammer, Purex, Persil and Tide.[1] They first became popular in February 2012 when they were introduced by Procter & Gamble as Tide Pods.[1]

This is a type of Tide Pod, a typical laundry detergent pod.

The chemistry of laundry detergent packs is the same as in liquid detergents (including alkylbenzenesulfonates). The water-soluble pouch is typically made of polyvinylalcohol (PVA) or a derivative of PVA. Although the formulas are similar, a detergent pack's liquids may contain only 10% water compared to 50% in liquid detergents.[2]

MonoSol is one of the companies that develops the water-soluble film used for laundry and dishwasher detergent packs, used by brands including Tide, with roughly $250 million in annual sales and controlling around 90-percent of the market.[3] The film is designed to be soluble within cold water.[4]

Laundry pods are estimated to make up about 15% of the $7 billion-a-year U.S. laundry detergent market sales according to market researcher Nielsen NV. Laundry pods attempt to reduce wasted use of powdered and liquid detergent by having precise measurements for a load. For large loads, most brands recommend two to three pods. The price of detergent pods can be higher than the liquid detergent for equivalent laundry loads.[5][6]

History

Laundry tabs were originally introduced in the 1960s in a compacted granular form (similar to an oral medical tablet), when Procter & Gamble launched Salvo tablets, later disappearing from the market in the 1970s. In the 1990s, Unilever and Henkel launched a similar laundry detergent pack product sold in Western Europe. These products sometimes didn't fully dissolve in United States washers.[7]

In 2005, Cot'n Wash, Inc. introduced liquid unit dose laundry pods under the Dropps brand.[8]

In 2012, Procter & Gamble relaunched a liquid tablet product as Tide Pods.[1] In late 2017, Internet memes centered around the concept of eating Tide's laundry detergent pods were popularized on Twitter.[9] Some companies are making edible replica "pods".[10] These memes have actually led to people eating pods on camera.[11] Ingestion of pods can cause death in some cases.[12]

Poisonings

Concern has been raised over children accidentally being exposed to laundry packs, as its appearance and the packaging design can have the same appeal to a child as hard candy with patterned designs, and be confused as such.[13]

In 2012, in response to a child swallowing Tide Pods, Procter & Gamble said they would make this product more difficult to open by adding a double latch to the lid, and has also re-focused their advertising to make clear the product should be out of a child's reach at all times. The packaging was also changed to an opaque orange rather than the original clear plastic gumball machine-type presentation to make them look less enticing; other manufacturers followed suit with equivalent packaging changes.[14] In 2013, Consumer Reports stated that there had been nearly 7,700 reported incidents in which children age 5 or younger had been exposed to laundry pacs,[1] and that year, one child from Florida died after ingesting a pac.[15] In 2014, a study published in Pediatrics found that from 2012 to 2013, more than 17,000 calls were made to poison control centers about children who had been exposed to the pacs.[16] Despite the industry's move toward safer packaging, a 2017 study published in JAMA Ophthalmology found that between 2012 and 2015, the number of chemical eye burns associated with laundry detergent pods among 3- to 4-year-old children skyrocketed from fewer than 20 to almost 500 per year; in 2015, these injuries were responsible for 26% of all chemical eye burns among this population.[17]

Beginning in late 2017 there arose a viral trend called the "Tide Pod Challenge", in which participants intentionally ingest detergent pods. Several children and teens have been injured, some severely, from this intentional consumption.[18]
