Emulsifiers are unique ingredients that are responsible for blending together components that typically do not play as well together, such as oil and water. While the term “glyceryl stearate” may seem strange and technical, these ingredients play a very important role in many foods we eat everyday and in the products we slather on our bodies. In this Article, we will explore about emulsifiers, their working, their use in preserving the edibles & making cosmetics creamy.
Emulsifiers are what help keep many of the foods we love fresh — and tasty — longer. Think of it like making salad dressing at home. You may have noticed that it can be pretty difficult to mix oil and vinegar together because they don’t naturally combine very well. Save the day coming in to the rescue is emulsifiers! They assist in developing a steady emulsion that won’t separate — meaning that the dressing will continue to be creamy and delectable for an extended time.
But alcohol stearyls aren’t only in salad dressings! The food additives are also used in many different types of processed foods that we love to eat, such as ice cream, mayonnaise, and even bread. Without emulsifiers, these foods would spoil more quickly and be far more difficult to produce. Emulsifiers work tirelessly to maintain these types of foods from separating and ensure they stay fresh and tasty longer.
As in food, emulsifiers in cosmetics help blend together ingredients that don’t necessarily mix well. In lotions and creams, they help mix oil and water so that the final product has a smooth, creamy texture. Without them, these cosmetics would layer in separate strata, rendering them difficult or even impossible to use.
Now, let’s talk about how emulsifiers really work. The key lies in something known as surface tension. Surface tension is what causes the water droplets to stick together and form a ball shape on smoother surfaces. Emulsifiers are different because they reduce the surface tension between oil and water, so the two can mix more easily.
Emulsifiers have one end that loves water and another xhat loves oil. The part of the molecule that loves water sticks to water droplets, and the part that loves oil grabs onto oil droplets. This incredible duo creates a stable emulsification, decreasing surface tension and forcing a homogeneous blend of the oil-water mixture.
As we described earlier, emulsifiers are really significant in the production of salad dressings. Without emulsifiers, though, the oil and vinegar would quickly separate, ruining the dressing’s texture and flavor. This would not only reduce the enjoyment of the dressing, but also make it necessary to shake or stir it every time you wanted to use it.
