Stearic acid ; It is the most known 18-carbon long chain aliphatic saturated fatty acid in nature. It is found in solid-liquid oils obtained from most animals and plants. Stearic acid and its compounds, especially salts (stearates) have an important place in the chemical industry.
Applications
Calcium stearate is a calcium carboxylate salt classified as calcium soap. Salt is a component of some lubricants, surfactants, as well as many foodstuffs. It is a white waxy powder
2 C17H35COOH + CaO → (C17H35COO)2Ca + H2O
Calcium stearate is a waxy material with low solubility in water, unlike conventional sodium and potassium soaps. It is also easy and inexpensive to manufacture and exhibits low toxicity. These qualities are the basis of most of its applications.
Applications: It is an excellent process facilitator used in injection and extrusion processes. It increases product homogeneity, reduces energy consumption and saves on raw materials. It is also used as a stabilizer, with which it is possible to achieve better transparency, good color retention, long-term stability and weather resistance properties. It is used as an anti-caking agent in cosmetic, pharmaceutical, food and chemical formulations due to its lubricating and water-repellent properties. It prevents products from absorbing moisture and sticking, increases plasticity. Calcium stearate is added to increase efficiency in production by extruding and laminating plastics and metals. They are used as a water repellent agent in joint, plaster and waterproofing products in the production of construction chemicals.
It is a waterproofing agent for fabrics. Lubricant in pencils and crayons. A lubricant in the dry drawing method of wire production The concrete industry uses calcium stearate for efflorescence control and waterproofing of cementitious products used in the manufacture of concrete wall units such as pavers and blocks. In paper production, calcium stearate is used as a lubricant to provide a good gloss and to prevent dusting and folding cracking in paper and board making.
Zinc stearate is a “zinc soap” widely used industrially. In this context, soap is used in its formal sense as the metal salt of a fatty acid: in this case, stearic acid. It is a white solid that repels water. It is insoluble in polar solvents such as alcohol and ether, but dissolves in aromatic hydrocarbons (e.g. benzene) and chlorinated hydrocarbons when heated. It is the strongest mold release agent among all metal soaps. It does not contain electrolytes and has a hydrophobic effect. Its main areas of application are in the plastics and rubber industries, where it is used as an easily incorporated release agent and lubricant.
Zinc carboxylates, eg. basic zinc acetate adopts complex formulas and is not just zinc dicarboxylates. Instead, the formula for most zinc carboxylates is Zn4O(O2CR)6 and consists of a Zn4O6+ core with flanking carboxylate ligands.
Applications : It can be used in many different building materials, especially joint materials. These products, which have the appearance of a white powder, are insoluble in cold water. Zinc stearate, which acts as a stabilizer for plastic products, is also preferred in the plastics industry. Zinc stearate, which is preferred in tablet production, varnishes and cosmetics industry, should be stored in a dry and cool area. Zinc stearate is also preferred in paint, construction chemicals, textile, paper, cosmetics and concrete industries. Zinc stearate, which is used for different purposes such as cable industry, construction chemicals, is also preferred in coating additives and paint additives.
It is widely used as a release agent for the manufacture of many kinds of objects, such as rubber, polyurethane, polyester processing system, powder metallurgy. These applications take advantage of its “non-stick” properties. In cosmetics, zinc stearate is a lubricant and thickening agent used to improve texture. Because it is lipophilic, it acts as a phase transfer catalyst for the saponification of oils. It is a component of some gloss paints.
