WebHLB numbers range from 1 to 30 (perhaps higher). For instance, if a surfactant has an HLB = 1, it is considered very oil soluble, while a surfactant with an HLB = 15 is considered to be water soluble. The HLB number is also a measure of the percent ethoxylation (EO) of the respective surfactant.
