  • Enzymes for recreational water
    Patent number: 5474701
    Abstract: An enzyme composition of matter is disclosed for reducing the amount of acylglycerol esters in water comprising a lipase enzyme, a non-ionic emulsifying agent, a water soluble organic acid preservative and a water soluble stabilizer. The lipase enzyme can be used in conjunction with other enzymes. The non-ionic emulsifying agent can comprise an alcohol ethoxylate, the water soluble organic acid preservative can comprise sorbic acid and the water soluble stabilizer can comprise glycerol. A method for treating water containing acylglycerol esters with the foregoing compositions is also disclosed.
