Propargyl alcohol propoxylate is an organic acid used in chemical mechanical polishing (cmp) compositions as a corrosion inhibitor. It has been shown to inhibit the growth of erythromycin-resistant bacteria by binding to metal ions. It also has surfactant properties and can be used as a surfactant or emulsifier in detergents, cosmetics and other products. The phosphite group provides a carboxylate group which reacts with the metal on the surface of the pipe to inhibit corrosion.

Propargyl alcohol propoxylate (PAP) is a clear colorless to yellowish liquid.

Propargyl alcohol propoxylate (PAP) is the condensate of propargyl alcohol and propylene oxide, which is used as brightener and leveling agent for nickel plating.

PAP is an enzyme produced by the prostate. It may be found in increased amounts in men who have prostate cancer. Also called prostatic acid phosphatase.

PAP (propoxylated propargyl alcohol, propoxylated alcohol, propargyl alcohol propoxylate) is the reaction product of 2-propyn-1-ol with methyloxirane. It is the simplest stable alcohol that contains an alkene functional group. It is a top brightener in nickel electroplating baths at a concentration of 10-30 mg/L. It is also used in rust removers, acid cleaners, car wash equipment, and acid rim cleaners.
