It is a bit solid and has a pungent and oily odor. Retrieved January 7, 2021 from. Molecular Weight ： 284.48. The compound is soluble in carbon tetrachloride, carbon disulfide, and methyl formate (even known as methyl methanoate). Hence because of this combination, there are various uses of stearic acid as a surfactant and softening agent. 2. [17], Stearic acid is mainly used in the production of detergents, soaps, and cosmetics such as shampoos and shaving cream products. 1 gram dissolves in 21 ml alcohol, 5 ml benzene, 2 ml chloroform, 26 ml acetone, 6 ml carbon tetrachloride, 3.4 ml carbon disulfide." It is a significant component found in shea butter and cocoa butter. [12] Commercial stearic acid is often a mixture of stearic and palmitic acids, although purified stearic acid is available. While in chloroform, the solubility of stearic acid is 15.54 grams per hundred grams. As its ester, stearic acid is one of the most common saturated fatty acids found in nature following palmitic acid. Stearates and esters are its salts. [18], When reacted with zinc it forms zinc stearate, which is used as a lubricant for playing cards (fanning powder) to ensure a smooth motion when fanning. Properties: single product is white with a slight sheen of waxy crystal dice. Stearic acid is used along with castor oil for preparing softeners in textile sizing. PRODUCT NAME: STEARIC ACID. Metals can be stored for a long time, as stearic acid prevents oxidation. Also, this chemical compound is combustible and gets heated spontaneously, which can irritate the respiratory system and the skin too. Stearic acid undergoes the typical reactions of saturated carboxylic acids, a notable one being reduction to stearyl alcohol, and esterification with a range of alcohols. The stearic acid content used in this is a triglyceride (derived from three molecules), and it is up to 28 – 45%. Wherein acetyl-CoA contributes to two-carbon building blocks. What Does Stearic Acid do to the Skin? Moreover, Stearic acid goes through the typical reactions of saturated carboxylic acids because of which it is used with drinks also. Fatty acids are classic components of candle-making. It does not even clog pores, and it is also safer for sensitive skin, although if there is any irritation faced, it's better to do a sensitivity test before application. It is a bit solid and has a pungent and oily odor. Its name comes from the Greek word στέαρ "stéar", which means tallow. The chemical formula is C. . As a coat for aluminium and iron powder, for preventing oxidation. It has a waxy texture. The important exceptions are the foods cocoa butter (34%)[13] and shea butter, where the stearic acid content (as a triglyceride) is 28–45%. Repeaters, Vedantu Stearic Acid, Triple Pressed Stearic Acid, Stearic Acid Price manufacturer / supplier in China, offering Single/Two/Triple Pressed Stearic Acid for Plastic & Rubber Grade, White Powder Polyvinyl Chlorid Sg-5 PVC Resin K-67, High Performance Pipe Grade Sg5 PVC Resin with Cheap Price and so on. It is insoluble in water, and slightly soluble in ethanol. ... group that can be attached to metal cations and a … The commercial stearic acid is always a mixture of stearic and palmitic acids, although one can choose purified stearic acid if it's available. Pro Subscription, JEE Soluble in acetone. [citation needed], In general, the applications of stearic acid exploit its bifunctional character, with a polar head group that can be attached to metal cations and a nonpolar chain that confers solubility in organic solvents. Boca Raton: CRC Press, 2007. that “like dissolve like”, stearic acid will be more soluble in non-polar solvents and less soluble in polar solvents. [19] It is also used as a mold release for foam latex that is baked in stone molds. The triglyceride derived from three molecules of stearic acid is called stearin. The combination leads to uses as a surfactant and softening agent. Stearic acid is an 18 carbon chain, saturated fatty acid. "Solubility: Easily soluble in diethyl ether. For example, it is moderately soluble in alcohols, phenyls, and alkyl acetates. The creamy yet waxy texture of stearic acid is very gentle, and hence it's used in the body care product. What Is Stearic Acid. Stearic Acid Products Made In China, China Trading Company. Applications: Stearic acid is an important chemical raw material and additive, widely used in food, rubber, plastic, cosmetics, drugs and auxiliaries. While in chloroform,  the solubility of stearic acid is 15.54 grams per hundred grams. And it is slightly soluble in cold water, soluble in alcohol and acetone, and easily soluble in benzene, chloroform, ether, carbon tetrachloride, carbon disulfide, amyl acetate and toluene. It is a waxy solid and its chemical formula is C17H35CO2H. But when stearic acid is accumulated with magnesium, magnesium stearate is formed, which is harmful and can have different side effects if consumed. Chemical formula: CH 3 (CH 2) 16 COOH. Many research has proved the safety of stearic acid. According to the MSDS, it is easily soluble in diethyl ether, and soluble in acetone. CAS Registry Number ： 57-11-4. The chemical formula is C18H36O2. Lithium stearate is an important component of grease. Stearic acid is an important chemical raw material. It has a waxy texture. Typical Physical Properties Package: [citation needed], Being inexpensive, nontoxic, and fairly inert, stearic acid finds many niche applications. As its ester, stearic acid is one of the most common saturated fatty acids found in nature following palmitic acid. Pro Lite, CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. [citation needed], Stearic acid (E number E570) is found in some foods. They are added to the product in molten form and allowed to crystallize under controlled conditions. Bulkbuy PVC Internal Lubricant Stearic Acid price comparison, get China PVC Internal Lubricant Stearic Acid price comparison from Triple Pressed Stearic Acid,Stearic Acid 1840 manufacturers & suppliers on Video Channel of Made-in-China.com . The resultant mixture is then distilled. Soluble in alcohol, chloroform, carbon disulfide, carbon tetrachloride, amyl acetate, toluene. And the significant reason behind the use of stearic acid in all these products is, it's very inexpensive, relatively inert and non-toxic too. Related salts are also commonly used as release agents, e.g. Ammonia and Nitric Acid Formulae Properties Preparation, Difference Between Acetic Acid and Glacial Acetic Acid, Vedantu Stearic acid is a type of saturated fat used in different diets. it is soluble in chloroform or ether, dissolved in ethanol, almost insoluble in water. Stearic acid (/ˈstɪərɪk/ STEER-ik, /stiˈærɪk/ stee-ARR-ik) is a saturated fatty acid with an 18-carbon chain. China Stearic Acid 98% with Wholesale Price, Find details about China Stearic Acid, Casting from Stearic Acid 98% with Wholesale Price - NANJING LETS IMPORT & EXPORT CO., LTD. Stearic acid is not relatively soluble in water, only a fraction of a milligram of stearic acid can be liquefied in as much as a hundred grams of water. In epidemiologic and clinical studies, stearic acid was found to be associated with lowered LDL cholesterol in comparison with other saturated fatty acids.[21]. [citation needed], In view of the soft texture of the sodium salt, which is the main component of soap, other salts are also useful for their lubricating properties. Stearic acid is obtained from fats and oils by the saponification of the triglycerides using hot water (about 100 °C).
