Physical constants, i.e. surface tension, partial specific volume, reduced viscosity, and refractive index, were measured with a mixture of 10 kind of solubilizing agent and water. Mixed solutions of having only hydrophilic group, ethylene glycol, diethylene glycol, triethylene glycol with water did not show a break in the foregoing physical properties and these stubstances were considered not to undergo association. On the other hand, substances having both hydrophobic and hydrophilic groups, such as cellosolve, butylcellosolve, carbitol, butylcarbitol, hexylene glycol, dipropylene glycol and diethylin with water showed a break in physical properties, suggesting that association occurred in these mixtures at a certain concentration of these substances, resulting in a sudden change in their internal structure. A mixed solutions of butylcellosolve, butylcarbitol, hexylene glycol, and diethylin with water showed a clear break point in physical properties suggesting that they are highly associated in the solution.
