Laundry detergent pods

Laundry detergent pods (also called "packs" or "liquitabs") are water-soluble pouches containing highly concentrated laundry detergent, softener and other laundry products. They first became popular in February 2012 when they were introduced by Procter & Gamble as Tide Pods (Ariel Pods in Europe).[1]

The chemistry of laundry detergent packs is the same as in liquid detergents (including alkylbenzenesulfonates). The dissolvable packets are typically made of polyvinyl alcohol (PVA) or a derivative of PVA. Although the formulas are similar, the concentration varies; the liquid components of a detergent pod may contain 10% water compared to 50% in liquid detergents.[2] The film is designed to be soluble in cold water.[3] While PVA is water-soluble and technically biodegradable under specific conditions, it is estimated that close to 15,000 metric tons of intact PVA either bypass or make it through treatment facilities every year.[4]

Laundry pods are estimated to make up about 15% of the US$7 billion-a-year U.S. laundry detergent market sales according to market researcher Nielsen NV. Laundry pods were advertised as a way to reduce wasted use of powdered and liquid detergent by having precise measurements for a load. For large loads, most brands recommend two pods, with Tide suggesting up to three. Detergent pods cost significantly more than liquid detergent for equivalent laundry loads.[5][6] 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 US$250 million in annual sales and controlling around 90-percent of the market.[7]

Notable brands of these packs include All, Arm & Hammer, Gain, Purex, Persil, Rinso and Tide.[1]
