Albumen is both a thickening and a fixing agent for insoluble pigments such as chrome yellow. Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene having numerous applications such as low friction bearings, non-stick pans, anticorrosive coating materials etc. Hence, P, Q, R are used as thickening agents for textiles and papers.
