“…For the alkyl polyxylosides, Krafft point was also used to evaluate the water solubility, the Krafft points of octyl polyxyloside (DP = 1.2), decyl polyxyloside (DP = 1.1), and dodecyl polyxyloside (DP = 1.2) were 21, 36.2, and 44.9 °C, respectively, indicating that octyl polyxyloside (DP = 1.2, HLB = 12.2) had rather low water solubility, decyl polyxyloside (DP = 1.1, HLB = 10.7), and dodecyl polyxyloside (DP = 1.2, HLB = 10.2) have low water solubility as they have low DP (near 1) (Renault, Portella, Marinkovic, & Estrine, ). For alkyl glucoside and alkyl galactoside, e.g., octyl β‐ d‐ glucoside, octyl α ‐ d‐ glucoside, octyl β‐ d‐ galactoside, and octyl α ‐ d‐ galactoside have same HLB number (12.3), and their water solubilities were 0.60 (Liu et al, ), 0.05 (Li, Chen, Chen, Shen, & Ji, ), 1.07, and 10.02 g/100 mL (water) at room temperature (Chen et al, ; Chen, Li, et al, ). They are different from each other, indicating that the glycosyl head and anomeric configuration affect the water solubility in spite of identical HLB numbers.…”
