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.
Cleavable detergent Cleavable detergent Cleavable detergents, also known as cleavable surfactants, are special surfactants (detergents) that are used in biochemistry and especially in proteomics to enhance protein denaturation and solubility. The detergent is rendered inactive by cleavage, usually under acidic conditions, in order to make the sample compatible with a following procedure or in order to selectively remove the cleavage products. Applications for cleavable detergents include protease digestion of proteins such as in-gel digestion with trypsin after SDS PAGE and peptide extractions from electrophoresis gels. Cleavable detergents are mainly used in sample preparations for mass spectrometry. PPS, available as PPS Silent Surfactant
