Sulfated monoglycerides

The phase behavior of surfactant systems is particularly complex because of the existence of numerous lyotropic (solvent-induced) liquid crystal phases (3). These phases, like liquids and crystals, are discrete states of matter. They are fluids, but their x-ray patterns display sharp lines signifying the existence of considerable structure. They are often extremely viscous because of their high viscosities and for other reasons they are difficult to study using conventional methods. This is evident from the fact that serious errors in the presumably well-established classical aqueous phase diagrams of soaps, sodium alkyl sulfates, monoglycerides, and... 

Use of Solvents. Organic solvents are sometimes used commercially to purify sulfonates or sulfates. Alcohols (methanol, ethanol, isopropanol) are employed to desalt and purify sodium dodecylbenzenesulfonate, sulfated monoglycerides, sulfated long-chain alkenes, and petroleum sulfonates. Sodium sulfate is insoluble, while the sulfonate dissolves in the alcr l. In the last two cases, separation of unreacted hydrocarbon is also effected, yielding a purer product further removal of the hydrocarbon is often achieved by extraction of the alcoholic sulfcmate solution with petroleum naphtha solvent. This purification scheme has also been used commercially to produce dodecylbenzenesulfonate detergents of low residual hydrocarbon content. ...

Fats and Oils. Fats and oils (6) are traditionally sulfated using concentrated sulfuric acid. These are produced by the sulfation of hydroxyl groups and/or double bonds on the fatty acid portion of the triglyceride. Reactions across a double bond are very fast, whereas sulfation of the hydroxyl group is much slower. Yet 12-hydroxyoleic acid sulfates almost exclusively at the hydroxyl group. The product is generally a complex mixture of sulfated di-and monoglycerides, and even free fatty acids. Other feeds are castor oil, fish oil, tallow, and sperm oil.

There is plenty of information available in literature on liquid crystalline and isotropic phases of different surfactants, but the study of the solid phases is limited to only soaps [12-19]. The basic reason for the lack of solid phase studies of synthetic surfactants is their limited use in solid form. The low KP of these surfactants limits their use to liquid products. Owing to a relatively high KP, sodium cocoyl isethionate (SCI), alkyl glycerol ether sulfonate (AGES), and sodium cocoyl monoglyceride sulfate (CMOS) form solid phases at room temperature, but there is hardly any information available on these solid phases. 

Emulsifiers are surface active substances that modify interfacial eneigy at the interface of immiscible systems. Emulsifiers are often required in the film formation to disperse lipid particles in composite emulsion films or to achieve sufficient surface wettability to ensure proper surface coverage and adhesion to the coated surface (Krochta 2002). Some common emulsifiers are acetylated monoglyceride, lecithin, glycerol monopal-mitate, glycerol monostearate, polysoibate 60, polysoibate 65, polysoibate 80, sodium lauryl sulfate, sodium stearoyl lactylate, soibitan monooleate, and soibitan monostearate (Janjarasskul and Krochta, 2010).
