Methyl stearate can be made from hydrogenation of methyl oleate (converting double bond into single bond). Methyl stearate is a solid at room temperature while methyl oleate is liquid.
Methyl stearate is used as emolient; propylene glycol is used as humectant, preservative and solvent.
Methyl stearate is a chemical often used as an emulsifying agent commonly found in cosmetics and drugs. It is classified as an ester from methyl alcohol and stearic acid.
The enzyme which catalyzes the conversion of stearate to oleate is stearoyl-CoA desaturase.
Its functional group is carboxylic acid i.e. COOH. Having chemical formula C17H35COOCH3 Colorless crystals melting at 39°C; soluble in alcohol and ether, insoluble in water; used as an intermediate for stearic acid manufacture.
One side methyl group- otherwise virtually identical identical- formula is the same. I bet the properties are very close. That methyl group in isopropyl hexadeconoate probably has a bit more effect on the oxyl main chain than if it was far away- probably slightly more acidic.
methyl stearate will react with triethanolamine to form an emulsifying agent. By itself, is not very goodin this respect

Biodiesel is composed of Fatty Acids with Methyl, Propyl or Ethyl Esters. Some common forms of biodiesel are Methyl Linoleate and Ethyl Stearate. ==Methyl Linoleate== Chemical Formula: C19H34O2 ==Ethyl Stearate== Chemical Formula: C20H40O2

Sodium oleate is an amphipathic compound.
The chemical formula of sodium oleate is C18H33NaO2.
Any metal salt of a fatty acid acts similarly to soap. So sodium oleate, lithium ricinoleate, potassium stearate etc are all examples. Also alkalis such as lye and animal fat will behave likewise.
One side methyl group- otherwise virtually identical identical- formula is the same. I bet the properties are very close. That methyl group in isopropyl hexadeconoate probably has a bit more effect on the oxyl main chain than if it was far away- probably slightly more acidic.
what is difference beetwin sodium stearate and potassium stearate
Ca2+Cl-2 + 2 Na+Oleate- = Ca2+Oleate-2 + 2 Na+Cl- ie: One molecule of Calcium Chloride + two molecules of Sodium Oleate leads to one molecule of Calcium Oleate plus two molecules of sodium chloride.
