Household liquids with low surface tension?

  1. Dec 7, 2008 #1
    I'm looking for household liquids, preferable kitchen/cooking liquids with a low surface tension. I know of soap water, alcohol, and found olive oil. Any other ideas would be appreciated. I'm looking for something in the mid to low 20's mN/m or less.

    Thanks,
    -Eric

    I had the opportunity to visit a PQ Corporation facility in Utica, Il. recently. They manufacture "liquid glass" --> Sodium Silicate. Sodium Silicate is surfactant ie. lowers surface tension in liquids. Please note Sodium Silicate is NOT a "kitchen/cooking" liquid and is mildly caustic. Exercise care if this is something you're looking for and happen to get your hands on.
