The IUPAC name is octadecanoic acid. It is a waxy solid and its chemical formula is C17H35CO2H. Its name comes from the Greek word \u03c3\u03c4\u03ad\u03b1\u03c1 &#8220;st\u00e9ar&#8221;, which means tallow. The salts and esters of stearic acid are called stearates. As its ester, stearic acid is one of the most common saturated fatty acids found in nature following palmitic acid. The triglyceride derived from three molecules of stearic acid is called stearin.<\/p>\n<p>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. The combination leads to uses as a surfactant and softening agent. 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. This is used in a large range of manufactures, from simple to complex electronic devices.<\/p>\n","protected":false},"featured_media":15080,"template":"","meta":[],"product_brand":[],"product_cat":[199,193,202,203],"product_tag":[],"class_list":{"0":"post-15079","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-all-products","7":"product_cat-cosmetics-industry","8":"product_cat-household-chemicals","9":"product_cat-pharmaceutical-industry","11":"first","12":"outofstock","13":"taxable","14":"shipping-taxable","15":"purchasable","16":"product-type-variable","17":"has-default-attributes","18":"rtwpvg-product"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Stearic Acid (CAS 67701-03-5) - MasterChem | kemikaalien tuotanto ja myynti<\/title>\n<meta name=\"description\" content=\"Stearic acid is a saturated fatty acid with an 18-carbon chain.
