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.
WIN (detergent) system. Hydrogen peroxide also provides a more gentle bleaching action than chlorine bleaches. Until WIN, peroxide bleach in a liquid detergent had not been marketed primarily to target sweat-caused bacteria in clothing. Oxy-based cleaning systems necessitate a lower pH, which makes them generally less effective on certain household stains like oil or food, and can be difficult to formulate due to stability issues created by a loss of available oxygen over periods of time. However, WIN’s cleaning system was designed not to be a general use detergent formula, but rather, to address the needs of its sports enthusiast target market.
