LiquaPar Oil preservative is a 100% active, clear, stable, liquid blend of isopropyl, isobutyl, and butyl esters of parahydroxybenzoic acid. Each of these ingredients is itself a solid but when manufactured in our patented combination, they form a unique and effective clear liquid preservative. LiquaPar Oil preservative is effective against Gram-positive bacteria, yeast and mold. The higher alkyl esters present in LiquaPar Oil preservative are not only more active, but also are more stable and up to three times more resistant to hydrolysis than traditional lower alkyl powder parabens.
