Most foods exists as emulsions( sauces, milk,ice cream,butter etc). An emulsion consists of two immiscible phases. The emulsifier is a food additive that is added to produce a stable emulsion. The emulsifiers are amphiphilic molecules(i.e., molecules having both polar and non polar groups) and hence bring together the two immiscible substances.
It is used as emulsifiers.
People can be allergic to some emulsifiers used in dairy products such as eggs
Emulsifiers are commonly used in food products to stabilize and improve texture. When consumed in moderate amounts, they are generally considered safe for humans. However, excessive consumption of emulsifiers may disrupt the gut microbiome and potentially contribute to inflammation and related health issues.
Some alternative food-grade emulsifiers to replace polysorbate 80 are lecithin, mono- and diglycerides, and sorbitan monostearate. These emulsifiers can help improve stability and texture in various food products without the need for polysorbate 80.
Emulsifiers can be eggs etc so people can be allergic to it
Emollients are substances that soften and soothe the skin. They are used to correct dryness and scaling of the skin. They are a key component in the manufacture of lipstick, lotions, and other cosmetic products. The terms "moisturizer" (something that adds moisture) and "emollient" (something that softens) are sometimes used interchangeably, as they describe different effects of these agents on the skin. However, the term emollient is most often used to describe single ingredients, whereas "moisturizer" describes finished products.
Emulsifiers are added to food to improve stability and texture by preventing ingredients from separating or clumping together. They help create a smoother and more consistent texture in products like salad dressings, mayonnaise, and ice cream. Additionally, emulsifiers can extend shelf life and improve overall food quality.
An emulsifier binds oil and water in food to prevent them from separating. The most frequently used raw materials for emulsifiers include palm oil, rapeseed oil, soy bean oil, sunflower oil or lard/tallow. You need to read the ingredients on a food product to see if it contains pork or lard, or look for the Kosher symbol which guarantees that the food is free of pork products.
Natural emulsifiers like soy, milk, and eggs can be dangerous to those allergic to them by triggering a potentially deadly allergic reaction called anaphylaxis. Mono-diglycerides (hydrogenated oils) are a synthetic emulsifier also used in food. They contain trans fats which increase cholesterol levels and the risk of stroke and heart attack, and clog arteries.

Emulsifiers are commonly found in lotions and foods, however, some are very dangerous. Their function is to interact with fatty acids, protein and water to make oil water mixtures stable. In my mind, I don't want any emulsifiers messing with my body over the long term. I avoid them in food and cosmetics. The only company making emulsifier free lotion is Ceela naturals.
Food additives are substances added to food to preserve flavor or enhance its taste and appearance, for example food acids like vinegar, emulsifiers used in ice cream or homogenised milk etc...
