Disadvantages of stearic acid–melamine repellents include problems similar to durable press finishes (a tendency to exhibit finish mark-off, decreased fabric tear strength and abrasion resistance, changes in shade of dyed fabric, and release of formaldehyde). Magnesium stearate can be created by a reaction of magnesium sulfate, which is soluble in water, with sodium stearate, and the magnesium stearate would deposit in solution because it is insoluble in water. While alcohols, acids, and their salts are generally soluble, esters are generally insoluble in water. The FTIR analysis shows that the bonding of the carboxyl group was broken and transformed to the carboxylate bidentate on the surface of zinc oxide.

I am assuming that when you say sugar you mean sucrose and when you say alcohol you mean ethyl alcohol. If magnesium chloride exists in solution other than magnesium stearate, then sodium chloride would also be produced. Advantages of the stearic acid-melamine repellents include increased durability to laundering and a full hand imparted to treated fabrics. As a fatty acid, stearic acid is a relatively non-polar compound. The anode and cathode should be made of copper. Brandreth DA and Johnson RE: J Chem Eng Data 16 (1971), 325-7.

The solubility of stearic acid in ethanol, methanol, ethyl acetate, and acetone has been measured gravimetrically at various temperatures ranging from 301 to 313 K at atmospheric condition. Eng. (2001) indicate that stearic acid (19 g/day) in the diet has favorable effects on thrombogenic and atherogenic risk factors in males; the authors recommend that the food industry consider enriching foods with stearic acid instead of palmitic acid and trans fatty acids. It is a waxy solid and its chemical formula is C17H35CO2H. Its name comes from the Greek word στέαρ "stéar", which means tallow. Acetic acid would be more soluble in ethanol since it is more polar than stearic acid. The solubility of palmitic acid in ethanol is approximately 30 mg/ml and approximately 20 mg/ml in DMSO and DMF. Stearic acid is more abundant in animal fat (up to 30%) than vegetable fat (typically <5%). it is soluble in chloroform or ether, dissolved in ethanol, almost insoluble in water. After cooling, filtration and washing with ethanol, the solid product was dried overnight at 50 °C. This solubility behavior may be explained by considering the polarity and … Sucrose or sugar is only slightly soluble in ethanol. Acetic acid is more soluble in ethanol than stearic acid BECAUSE acetic acid is like ethanol in terms of side and molar mass.
