Emulsifying agents are soluble in fat and water to allow uniform dispersion of fat in water. Emulsifying agents are also called emulsifiers and present in the food like butter, mayonnaise and salad dressing. These have one hydrophilic and one lipophilic part. These agents surrounds the oil droplets in water and reduces the tension between the two liquids thus impart stability.
Classification of Emulsifiers
These can be classified on the basis of chemical structure and mechanism of action. Under chemical structure category are synthetic, natural, auxiliary agents and finely dispersed solids. In the category of mechanism of action comes the monomolecular, multimolecular and solid particle films.
Natural emulsifying agents are derived from plant and animal tissues and mostly in the form of hydrated lypophilic colloids. These emulsifiers make the protective sheath around the droplets, give droplets a charge so that they repel each other and swell to step-up the viscosity of the liquid.
Natural ones are derived from vegetables, animals, semi synthetic and synthetic agents. Although natural agents are inexpensive, safe and non toxic but these are slow in action. So large quantity of emulsifier is required for proper action. Also the natural emulsifiers need preservatives as these are subjected to microbial growth.
The animal derivatives are stronger than the plant ones. The best example of this is lecithin and cholesterol. Some people are allergic to these so must be consumed after knowing the derivatives.
Both semi-synthetic and synthetic emulsifying agents are strong and require no preservative as these are not prone to microbial growth.
Applications of Emulsifying Agents
Emulsifiers are used in many types of food for stability and to reduce tension. Like vinaigrette if prepared only with oil and vinegar leads to unstable emulsion. To stabilize mayonnaise egg yolk lecithin is used as emulsifiers. Both natural as well as synthetic emulsifiers are used in food industry. Egg, soybean, rapeseed oil and palm oil are the common natural agents. Dairy products like cheese and ice creams use the emulsifying agents to improve the texture. Also the crystallization of candies is improved by them. Jarred peanut-butter and sauces are given more life with the use of correct emulsifier.
It is extensively used in pharmaceutical industry to make medicines more good to taste and easy to take. In pharmaceutical oil and water emulsions are basically used. These are also used in other industries like agriculture, paints and inks. Fertilizers and pesticides are given more stability with these.
Harmful Effects
Although the one used in food are completely safe and more over natural ones are safer than synthetic. But in some cosmetics certain harmful emulsifiers like polyethylene glycol (PEG) compounds, have been found that are carcinogenic. Also the emulsifying agents in body care products causes mild or severe allergies of skin.

Have you ever wondered what chemicals are used in your cosmetics? If you havent, then should start reading the ingredients that are used in some of your favourite cosmetics since some of them are toxic and dangerous to your health.
One of the most popular ingredients that is used in most cosmetic products and that one should be aware of is Triclosan. Simply put, Triclosan is an antibacterial and antifungal agent that is used for its antibacterial properties in products such as detergents, deodorants, lotions, anti-microbial creams and many other cosmetic products. That said; the safety of Triclosan has been in question especially when it comes to human and environmental health. Heres why:
According to the experts, Triclosan is a chlorophenol a class of chemical compounds that are suspected of causing cancer in human beings. Heres what is known about phenol compounds. For starters, when they are applied externally they can cause a variety of skin irritations that can at times deactivate sensory nerve endings temporarily with little or no pain to the host. When consumed, phenol compounds have been known to cause convulsions, cold sweats, coma and even death depending on the amount that was ingested. All these symptoms can be caused by Triclosan. There are also side effects that are associated with the long term exposure of phenol compounds. These include a suppressed immune system, hormonal imbalance and disruption, kidney failure, heart failure and even paralysis.
When it comes to cosmetic soaps that contain Triclosan, there is ongoing research that is investigating how this phenol compound impacts microbes biologically. The research was brought about by the emergence of resistant strains of bacteria. Scientists are arguing that Triclosan in cosmetic soaps is facilitating the survival and growth of new and more resistant strains of bacteria. In order to understand how this comes about we have to dig a little deeper into the biology of resistance.
When one uses a cosmetic soap that contains Triclosan, the phenol compound kills the majority of the microbes that are present and then leaves a few bacteria that have a special trait that can enable them to survive the destructive effects of Triclosan. What happens next is that the remaining microbes are now free to grow and pass on their special resistant trait to other microbes enabling them to survive. Once this happens, the microbes will eventually become robustly resistant to the chemical in question and can even spread their resistance to other micro-organisms via a genetic method known as transposon.
Please note that while the relationship between Triclosan and antibiotic resistance has been confirmed in the lab, inconclusive results have been recorded in the general population. It is believed that experiments with longer trial periods are required before bacterial resistance to Triclosan can be fully observed in humans.
