Have you ever seen how mayonnaise is made? Why is it that delicious? Egg yolk, water, and oil are mixed to form an emulsion. It is an oil-in-water emulsification process that is stabilized by egg yolk. Egg yolk contains lecithin, which can mix oil with water. What if the mayonnaise doesn’t mix well? You must be reluctant to eat it with bread a second time, right?
Emulsification in the Food Industry
Oil and water are always present in the food industry. These two materials can always be combined because of the emulsification process. The oil can be broken down to form small droplets that can dissolve into the water. We know that oil is insoluble in water, right? However, everything becomes possible with this emulsification process.
In the food industry, lecithin is often used as an emulsifier that keeps oil suspended in water. Lecithin is found in egg yolks. In addition, there are other emulsifiers in the food industry that occur naturally, such as milk. The whole milk you take from cows contains fat. The fat droplets on the cow form an emulsion on their own.
Milk also contains casein. It is a milk protein that is a natural emulsifier in foods. The history of the discovery of the term ‘emulsion’ that we know today comes from the Laton from ‘milk’. The job of an emulsifier is to coat the droplets of two different substances so that they remain separate from each other. Clumps will easily form when the two substances are left alone. Emulsifiers have a fat-soluble part and a water-soluble part.
Emulsification in Cosmetic Products
The final process of emulsification is easily found in products such as skin lotions, hair care products, and facial makeup. The way emulsifiers work in cosmetic products is less the same as in the food industry. In the cosmetic industry, emulsions are classified into several sections as below:
· Oil-free emulsion. You always see the products of this emulsion, such as gels and solutions.
· Water-free emulsion. The emulsion products are usually intended for skin that has certain disorders.
· Water-in-silicone emulsion (w/si). the products of this emulsion are either a hand cream or a barrier cream.
· Oil in water (o/w) emulsion. This is a condition where a low volume of oil is dispersed into a larger volume of water. To stabilize the o/w system, a hydrophilic surfactant is needed. It is a water-soluble surfactant with high HLB. Products that use this emulsion include moisturizing products such as day cream and body lotions.
· Water in oil (w/o) emulsion. This is a condition where a low volume of water is dispersed into a larger volume of oil. Lipophilic surfactants are used to stabilize w/o emulsions. It is an oil-soluble surfactant with low HLB. Stable w/o emulsions are obtained from high shear homogenizers applied to water added to an oil and hydrophobic emulsifying solution. The products that you usually encounter are sun protection creams and night creams.
· Oil in water in oil (w/o/w) emulsions can also be processed for particular conditions such as prolonged skin moisturization, sustainable fragrances, protection of skin sensitivities, and protecting incompatible materials from interacting with each other. The products from this kind of emulsification include a cleansing cream that has good spreadability, stable emulsion conditions, and good cleaning. There is also a smooth massage cream that even resembles a skin lotion in general.
Emulsification in Home Care Products
Your home may not always be clean and clear. Sometimes you find the floors get splattered with grease, the clothes get stubborn dirt stains, and the carpet is full of any kind of dirt. Emulsification products are widely found in household cleaners and laundry detergents. The product contains surfactants that emulsify oily dirt so that it can be diluted and can be cleaned easily.
On the other hand, laundry detergents generally contain ethoxylated alcohol. This mixture of non-ionic and anionic emulsifiers can remove stains from a wide variety of textiles. Greasy stains from good fats and vegetable oils can be easily removed by using an animator of medium polarities such as polypropylene oxide and polyethylene oxide.
Those of you who want to start a business in the household cleaning industry can also benefit greatly from the presence of qualified artificial emulsification products. You can get it from the cellulose ether manufacturer that produces cellulose products and has passed international quality certifications.
There is a factory in China that has been producing cellulose since 2006 with our annual output of 10000 tons. Their products are widely used in the coatings industry, building materials, medicine, agriculture, textile, cosmetic industry, ceramic industry, and many other industries. Emulsification functions can be easily removed from the products you manufacture using our cellulose.
Haircare, personal care, skin care, medicine, to other applications such as food products will be of higher selling value because it uses our cellulose polymer, which is tasteless, odorless, non-toxic, and good as a thickening agent, water retention agent, adhesive, stabilizer, film-forming agent, and many other uses. Contact us now to get the best emulsion so that the emulsification process of your products can be formed perfectly.
