12-hydroxystearic acid is prepared by the hydrogenation of castor oil, followed by saponification with sodium hydroxide and acidification with hydrochloric acid. [3] This process converts ricinoleate moieties in castor oil triglycerides to 12-hydroxystearate, with stearate as a byproduct from dehydration of the hydroxy acid followed by ...

Stearic acid (/ ˈ s t ɪər ɪ k / STEER-ik, / s t i ˈ ær ɪ k / stee-ARR-ik) is a saturated fatty acid with an 18-carbon chain. [9] The IUPAC name is octadecanoic acid. [9] It is a soft waxy solid with the formula CH 3 (CH 2) 16 CO 2 H. [9]
The C16 and C18 omega hydroxy acids 16-hydroxy palmitic acid and 18-hydroxy stearic acid are key monomers of cutin in the plant cuticle. [ 1 ] [ 2 ] The polymer cutin is formed by inter esterification of omega hydroxy acids and derivatives of them that are substituted in mid-chain, such as 10,16-dihydroxy palmitic acid.
12-Hydroxyeicosatetraenoic acid (12-HETE) is a derivative of the 20 carbon polyunsaturated fatty acid, arachidonic acid, containing a hydroxyl residue at carbon 12 and a 5Z,8Z,10E,14Z cis–trans configuration (Z=cis, E=trans) in its four double bonds.
Lithium stearate is a chemical compound with the formula LiO 2 C(CH 2) 16 CH 3.It is formally classified as a soap (a salt of a fatty acid).Lithium stearate is a white soft solid, prepared by the reaction of lithium hydroxide and stearic acid.
12-Hydroxyheptadecatrienoic acid (also termed 12-HHT, 12(S)-hydroxyheptadeca-5Z,8E,10E-trienoic acid, or 12(S)-HHTrE) is a 17 carbon metabolite of the 20 carbon polyunsaturated fatty acid, arachidonic acid. 12-HHT is less ambiguously termed 12-(S)-hydroxy-5Z,8E,10E-heptadecatrienoic acid to indicate the S stereoisomerism of its 12-hydroxyl ...
Glyceryl hydroxystearate is an ingredient found in some personal-care products. It is commonly used as an emollient, emulsifying agent, or bodying agent.It is often found in facial-care, foot-care, and lip-care products, sunblock, self-tanners, moisturizers, shampoos, creams, lotions, soaps, concealers, and roll-ons and sun-exposure treatments.
