    A Review: Preparation, Characterization and Applications of Magnesium Stearate, Cobalt Stearate and Copper Stearate
    (Nova Science Publishers, 2010) Egbuchunam, Theresa O.; Gönen, Mehmet; Balköse, Devrim; İnal, Fikret; Ülkü, Semra
    Metal soaps, such as zinc, calcium, copper, magnesium are insoluble or sparingly soluble in water. Because of this property, they are commercially important compounds and find applications in industry, such as driers in paints or inks, components of greases, stabilizers for plastics, in fungicides, catalysts, waterproofing agents, fuel additives, components of creams and additive in drug formulation and etc. Magnesium stearate is in widespread use as gelling, sanding and anti-sticking agents, stabilizer, lubricant, emulsifier and plasticizer for polymers, in the paint, food, rubber, paper and pharmaceutical industries. Copper stearate is used mainly for rot-proofing textiles, ropes, etc. It is also used in paints since they are soluble in oils, white spirits, etc. Quartz crystals coated with CuSt2 was used in the detection of volatile organic compounds. Cobalt stearate has applications in producing Co nests, mesoporous silica, as adhesion promoter. © 2014 by Nova Science Publishers, Inc. All rights reserved.

    Effect of Zinc Soaps of Rubber Seed Oil (rso) And/Or Epoxidised Rubber Seed Oil (erso) on the Thermal Stability of Pvc Plastigels
    (Elsevier Ltd., 2007) Egbuchunam, Theresa Obuajulu; Balköse, Devrim; Okieimen, Felix Ebhodaghe
    Zinc soaps of rubber seed oil (RSO) and epoxidised rubber seed oil (ERSO) were prepared and their use as PVC stabilizers investigated. Characterization of Zn soaps of RSO prepared by different techniques and ERSO gave information on the purity, structure and thermal behaviour of these materials. From the analysis, the production of these materials for use in thermal stabilization of PVC would be optimized as their use greatly enhanced the stability of PVC as obtained from the conductivity measurements using the 763 PVC Thermomat. The minimum amount of HCl release was obtained for the samples with Zn soaps and ERSO indicating a synergistic effect. Zn soaps having Zn(OH)2 stabilized PVC better than pure Zn soaps.
