“…The physical properties of the metal soap solutions exhibit a discontinuity at the cmc. The cmc values are summarized in Table . − It is difficult to compare the values of the different compounds in the table, because different solvent mixtures have been used. For one and the same solvent mixture, the cmc values were found to decrease with decreasing chain length of the lanthanide soap and to decrease over the lanthanide series.…”

“…The ultrasonic velocity of zirconyl soap in mixed organic solvents was studied by M. Anis [61] and calculated various acoustic parameters A. K. Sharma et.al [62] discussed various acoustic parameters of copper carboxylates. K. N. Mehrotra et.al [63] and Y. Sharma [64] reported ultrasonic results to find out the compressibility behavior of europium soaps in mixed organic solvents, and lithium laureate in a benzene-methanol mixture. The viscosity of cerium soaps in non-aqueous solvents was reported by R. Sharma [65] .…”

A review of the metallic soaps, preparation, mechanism, and their physicochemical properties in solid state as well as in solution. The properties of metallic soaps, including their state, stability, reactivity, volatility, and solubility in common solvents, are key factors that determine their potential applications and uses. The suitability of metallic soaps for specific purposes depends on their ability to meet the necessary physical requirements for a given application, such as their ability to remain stable under certain conditions or their solubility in specific solvents. By understanding these physical characteristics, researchers and industry professionals can determine the most effective ways to utilize metallic soaps in a variety of applications, from cosmetics to pharmaceuticals to industrial processes. This review highlights the diverse range of circumstances in which metallic soaps can be formed. These situations may involve composite objects made up of various materials containing fatty acids such as leather, and wood, in the presence of metals, metal alloys, or pigments. The formation of these metal soaps can occur in a variety of situations, which are explored in this collection.

The optical absorption spectra of neodymium(III) butanoate, pentanoate, hexanoate, heptanoate and octanoate in 1-pentanol have been measured. This solvent has been chosen, because the neodymium(III) soaps are sufficiently soluble in it. A set of free-ion parameters is obtained by fitting the calculated energy levels against the experimental levels. The experimental dipole strengths of the transitions are determined from the absorption spectra and parameterised in terms of the Judd-Ofelt intensity parameters V (l52, 4, 6). The V values l 4 go through a maximum for neodymium(III) hexanoate, whereas the V parameter increases in the order butanoate,pentanoate, 2 hexanoate,heptanoate,octanoate. The V parameter shows only an increase between the butanoate and the pentanoate complex, whereas 6 this parameter remains fairly constant for the higher homologues of the neodymium(III) soaps.
