Laundry detergent pod Laundry detergent pod Laundry detergent pods (or packs) are water-soluble pouches containing highly concentrated laundry detergent, softener and other laundry products. Notable brands of these packs include Arm & Hammer, Purex, Persil and Tide. They first became popular in February 2012 when they were introduced by Procter & Gamble as Tide Pods. The chemistry of laundry detergent packs is the same as in liquid detergents (including alkylbenzenesulfonates). The dissolvable packets is typically made of polyvinylalcohol (PVA) or a derivative of PVA. Although the formulas are similar, a detergent pack's liquids may contain 10% water compared to 50% in liquid detergents.
Laundry detergent cotton, wool, polyamide and polyacrylonitrile, sodium triphosphate removes soil more effectively than a surfactant alone. With hydrophobic fibres like polyesters and polyolefins, the effectiveness of the surfactant surpasses that of the builder. Surfactants are responsible for most of the cleaning performance in laundry detergent. They provide this by absorption and emulsification of soil into the water and also by reducing the water's surface tension to improve wetting. Laundry detergents contain mostly anionic and non-ionic surfactants. Cationic surfactants are normally incompatible with anionic detergents and have poor cleaning efficiency; they are employed only for certain special effects, as fabric softeners, antistatic
