Low VOC viscosity reducer (LVVR) compounds useful for reducing the viscosity of plastisol compositions. The plastisol compositions are combined with a viscosity reducing compound which is derived from the reaction of at least one of 2,2,4-trimethyl-1,3-pentane diol (TMPD) and 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (TXOL) with at least one of a carboxylic acid or a fatty acid.
