Jp. Wu et Tr. Gu, THE EFFECT OF ORGANIC ADDITIVES WITH MULT IPOLAR GROUP ON THE CLOUD POINT OF NONIONIC SURFACTANTS, Huaxue xuebao, 53(10), 1995, pp. 958-960
The effect of formic acid, acetic acid, oxalic acid, methanol, ethanol
, propanol, glycol, glycerol and glucose on the cloud point of nonioni
c surfactants Triton X-100 and Triton X-114 has been measured. The add
ition of lower aliphatic acids and alcohols increases the cloud point.
The longer the carbon chain length, the stronger the effect. The addi
tion of glycol increases the cloud point slightly, while the added oxa
ylic acid shows no significant effect. However, the addition of glycer
ol and particularly, glucose, decreases the cloud point drastically. T
hese effect are explained in terms of surfactant solubility.
