Several works have been reported of the concentration of oleyl oleate from sperm oil. But the oleate oleyl concentrated from sperm oil is so unstable due to the presence of highly unsaturated components that the application of oleyl oleate is limited. It is therefore, necessary to reduce these highly unsaturated components in the oleyl oleate concentrate. The authors attempted to decrease the amounts of polyunsaturated components in sperm body oil by two procedures. The one was to thermally polymerize sperm oil in the presence of active earth, and the other was to hydrogenate the oil selectively with Cu-Cr catalyst under atmospheric pressure. The oleyl oleate was concentrated from thus treated sperm body oils and untreated oil through molecular distillation and fractional crystallization. A.O.M. stabilities of these oleyl oleate concentrates were determined according to the A.O.C.S. analytical method. The oleyl oleate concentrate obtained from thermally polymerized sperm body oil was most stable, while the oleyl oleate from untreated sperm oil was unstable most.

The behavior of surfactant aggregates in solutions was investigated by an ESR spin probe method. The following informations were obtained from analysis of spectra. 1) Two types of micelles were directly observed in commercially available sodium alkyl poly (oxyethylene) ether sulfate-alkyl poly (oxyethylene) ether mixed surfactant solutions. 2) Sodium dodecyl sulfate molecules (2 mM) incorporated into phospholipid bilayers (13.6 mM) formed clusters by themselves, causing phase separation of the bilayers. 3) Sodium 3- dodecyloxypoly (oxyethylene) -1-propane sulfonates interacted with an ESR spin probe even below the cmc. This was explained by the formation of ESR spin probe-induced micelles. 4) Butyl poly (oxypropylene) ether derivatives having polar dissociative functional groups on their terminal hydroxyl groups behaved in a manner similar to a reversed micelle or a W/O microemulsion system and were inverted to an O/W type through a transparent and viscoelastic gel stage with increasing a water content.

Calcium ion sequestration capacities have been determined for eleven kinds of organic compounds in comparison with sodium tripolyphosphate (STPP) which is known as the most important detergent builder. The organic compounds used in this study were amino carboxylates (EDTA, NTA), hydroxy carboxylates (sodium lactate, tartarate, citrate, gluconate), and dicarboxylates (sodium oxalate, maleate, malonate, succinate, L-aspargmate). The sequestration capacities of these organic compounds depend on the pH of the solution. The most prominent characteristic of sodium citrate was found in the pH 9 region.

In the previous paper, the antioxidant effect of capsaicin, the pungent principle of red pepper, has been demonstrated. Capsaicin is a N-vanillylamide whose pungency has been known to depend upon the carbon chain length of the fatty acid moiety. In this paper, to obtain the pungent free N-vanillylamides, which are expected to be useful as antioxidants for foods, syntheses of N-vanillylamides of saturated C12 to C22 fatty acids were carried out, and their pungency and antioxidant activity were determined. As a result, their pungency reduced with the elongation of carbon chain of the fatty acid. That is, compared with C9 amide, the pungency of C14 amide was 1/100 and that of C18 amide decreased to 1/1000. On the other hand, the antioxygenic effect of each synthetic N-vanillylamide on methyl ester of safflower oil was almost equal to that of the natural pungent mixture extracted from red pepper. By addition of 0.02mol/kg of synthetic amides in the substrate, the antioxidant activity was equivalent to that of BHA in 0.02% level. In this level, pungency was not found in the sensory even for C12 amide.

A pseudo-first-order reaction constants (kobs) of dyes having a single hydroxyl group inthe molecule (Orange I, Orange II) by various bleaching agents were measured as a function ofpH. Used bleaching agents were hydrogen peroxide, peracetic acid, potassium permonosulfate, and sodium hypochlorite. The kobs of each dye showed maximum at intermediate pH betweenan acid dissociation constant of bleaching agent (pKa) and an acid dissociation constant of dye (pKd). Distribution curves of kobs on pH showed symmetrical narrow distribution when the value of pKd was close to pKa, and symmetrical broad distribution when the value of pKd was far apart from pKa. These results were analyzed with reaction kinetics by assumming the ionic reaction among protonated and deprotonated form of the bleaching agents and the dyes. It wasproved that the distribution curves of kobs on pH follow the following equation.kobs= [A] t/ (1+ [H+] /Ka) (1+Kd/ [H+]) where [A] t is the total bleaching agent concentration, k1 is a second-order reaction constant byassuming the reaction between protonated dye ; [DyeH] and deprotonated bleaching agents ; [A-]. The calculated values obtained by above equation were in good agreement with the observed values. Therefore, it was concluded that the decoloration mechanism of the dyes by bleaching agents conforms to the ionic reaction among protonated and deprotonated forms of the bleaching agents and the dyes. We have named this decoloration mechanism as “the mutual ionic reaction mechanism”.
