As an index of emulsification power for the complex, the particle size distribution and/or the average paticle size to liquid paraffin was measured by means of Coulter Counter in relation to the alkylchain length of triethanolamine (TEA) fatty acid, the molar ratio of TEA fatty acid to a cationic cellulose, the amount of complex and the kinds of surfactant:
1. The average particle size of liquid paraffin depended on the alkyl chain length of fatty acid to the aqueous solution of cationic celluse. The particle size was minimum at C14 in alkyl chain length of fatty acid.
2. In case of a cationic cellulose-TEA myristate complex, the particle size was changed according to the molar ratio of TEA myristate to cationic cellulose. The particle size gradually decreased with the increasing of the molar ratio up to 0.6. Above this point, it was nearly as same as that at the molar ratio of 0.6.
3. The particle size decreased with the increasing of the complex amount.
4. The particle size was changed by the kinds of anionic surfactant, with which cationic cellulose reacts to form a complex.
