BeschreibungMethyl 12-hydroxy stearate is won by direct esterfication of 12-Hydroxy stearic acid with methanol. Methyl 12-hydroxy stearate is sold in solid and liquid form. It is used in the continuous grease process. Greases made with Methyl 12-hydroxy stearate can be formulated to higher drop points. Greases experience less bleeding and improved oxidative stability. Methyl 12-hydroxy stearate is also used in textile ancillary, cosmetics and paper industry. appearance white to solid flakes or liquid melting point °C 45 - 53 AOCS Cc 1-25 colour (on 1” Lovibond) max. 3 yellow / max. 1,5 red AOCS 13e-92 acid value mg KOH/g max. 10 AOCS Cd 3d-63 iodine value 9 I2 /100g max. 5 AOCS Cd 1-25 hydroxyl value 160 - 178 AOCS Cd 13-60 saponification value mg KOH/g 170 - 180 AOCS Cd 3-25 water wt % max. 0,5 IS 548 unsaponifiable wt % max. 0,5 IS 548 titre of fatty acids °C 73 - 75 IS 548 Nickel + Iron ppm max. 10 ICP Sodium + Potassium ppm max. 20 ICP Magnesium + Calcium ppm max. 50 ICP

VerwendenMethyl 12-Hydroxystearate is a fatty acid reagent used in the study of sphingomyelin through site specific deuterium labelling. Also used in the preparation of ricinoleate-based lipoconjugates of phenolic acids for antioxidant and antifubgal properties.
