개요

Ricinoleic acid is an unsaturated omega-9 fatty acid and is an important component of the seed oil obtained from mature castor plants seeds. The compound is produced for industries by fractional distillation or saponification of hydrolysed castor oil. It is normally used in manufacturing personal care products such as deodorants. Much of ricinoleic acid characteristics and effects can be associated with castor oil.

화학적 성질

Ricinoleic acid (synonym castor oil fatty acid) is an unsaturated fatty acid prepared from castor oil. When Ricinoleic acid is pyrolyzed (heated in the absence of air), it breaks down in undecylenic acid and n-heptaldehyde.

용도

1. soaps: Ricinoleic acid can be reacted with various bases (caustic, ammonia, ethanolamines, etc.) to produce soaps having the desired characteristics (solubility, physical characteristics, polarity, etc.) depending on the final application. Some of them are: cutting oils, industrial lubricants, emulsifiers and metal working fluids. Transparent bar soaps & high solids liquids soaps are made possible by using Ricinoleic acid. The same for industrial germicides, disinfectants and heavy duty detergents (solubilization of phenolic and cresylic bodies).
2. surface coating: it is used as an efficient pigment/dye dispersants in inks, coatings, plastics, cosmetics, etc.
3. textiles: Ricinoleic acid provides polarity, surface wetting and lubricity.
4. rubber: the sodium/potassium soaps of Ricinoleic acid are emulsifiers and foam stabilizers.
5. vinyl polymers: it's sodium soap is useful as emulsifier, stabilizer and defoamer for emulsion polymerization of resins such as PVC & PVAc
6. food additives: it's used in the production of PGPR (polyglycerol polyricinoleate) for use in chocolate.

정의

ChEBI: Ricinoleic acid is a (9Z)-12-hydroxyoctadec-9-enoic acid in which the 12-hydroxy group has R-configuration. It is a conjugate acid of a ricinoleate. It is a C18 unsaturated fatty acid that comprises 80% of the fatty acid content of castor oil.

Carcinogenicity

Four rabbits given intermittent subcutaneous injections of 3120 mg/kg ricinoleic acid for 52 weeks developed subcutaneous neoplasms. The tumorigenic potential of ricinoleic acid injected intravaginally in groups of 20 mice was also studied. No tumors attributable to ricinoleic acid treatment were observed in three studies after 18–20 months.

Purification Methods

Purify it as the methyl acetylricinoleate [Rider J Am Chem Soc 53 4130 1931], fractionally distilling it at 180-185o/0.3mm, then 87g of this ester is hydrolysed by refluxing with KOH (56g), water (25mL), and MeOH (250mL) for 10minutes. The free acid is separated on acidification and extracted into Et2O, dried (Na2SO4), filtered, evaporated and the residue is crystallised from acetone at -50o, and distilled in small batches, b 180o/0.005mm. The R-enantiomer has m +5.5o, b 245o/10mm and [] 26D +7.2o (c 5, Me2CO). [Bailey et al. J Chem Soc 3027 1957, Beilstein 3 IV 1026, 1207.]
