Soy Lecithin will not dissolve in water but is soluble in fats/oils and soluble in ethanol.
Soy Lecithin is an amphiphilic substance. The acyl-chain portion in the molecule constitutes a hydrophobic region, the phosphate moiety constitutes a hydrophilic region. The hydrophobicity is stronger than hydrophilicity. Therefore, phospholipids are better soluble in organic solvents such as chloroform, and methanol, but the solubility is less solubility in a solvent with slightly larger polarity, insoluble in water.
The CMC value of the phospholipid in water is extremely low. The CMC value is spontaneously formed into a bimolecular layer vesicle structure. The solubility of the phospholipid is affected by a larger, and the natural source of phospholipids is usually soluble in alcohol than synthetic phospholipids.
Does Soy Lecithin dissolve in alcohol?
Soy Lecithin (or called phospholipids) is a mixture substance, phosphatidylcholine is one of them. When lecithin is mixed with alcohol, usually ethanol. Some phospholipids, such as phosphatidylcholine, have good solubility in ethanol. Most other phospholipids do not dissolve well in ethanol.
Soy Lecithin will dispersible in water
Emulsification is in the presence of lipids, and the phospholipid molecule is distributed in the form of a single molecular layer in the water in oil interface to become an emulsifier of two phases of the oil-water. The HLB value of the phospholipid is between 4 and 10, and the different phospholipids differ, and the suitable phospholipids are selected by the lipids are emulsifiers.
