All aspects of our lives contain colloids. Colloids can be seen with naked eyes and have properties that spread evenly. It is one of the three main types of mixtures apart from suspensions and solutions. The mist you see in the morning is a type of aerosol colloid. The milk you drink is an emulsion colloid type. Jelly, gelatin, dust, whipped cream, blood, ink, pearls, colored glass are examples of colloids that are all around us. Colloids are divided into several dispersed phases. They are formed from a gaseous, liquid, or solid dispersion medium. Colloid-producing manufacturers need protective colloid that makes colloidal particles not easily agglomerate or separate from the medium. Protective colloids commonly used include lecithin, gelatin, silicone oil, and casein. Now, some manufacturers make artificial protective colloids to facilitate the mass production of an item that you are working on.
Why Does Protective Colloid Appear?
Agglomeration is something that must be avoided in the colloid production process. Unfortunately, the interaction between the dispersed phase and the dispersing medium often causes agglomeration. This happens because of the nature of colloids which are easy to settle and are less stable.
Based on their properties, there are lyophilic colloids and lyophobic colloids. The big difference between the two is their affinity for the dispersing medium. Lyophilic colloids have high affinity so that the dispersed phase is not easy to precipitate and is stable.
Clumping also doesn’t occur because colloids with their dispersed phase easily interact with water. These lyophilic colloids are also known as hydrophilic colloids. If one day the dispersed phase separates from the dispersion medium, you can make this colloid again because it is easy to decompose and rearrange. We could find the reversible nature of colloids in starch, gelatin, protein, and micelles surfactant.
Meanwhile, low affinity always occurs in lyophobic colloids. If there is heating, shaking, and addition of electrolyte, this colloid easily precipitates. It is also classified as an unstable colloid which, when used, becomes too risky. Lyophobic colloids that we often encounter are gold sol, silver sol, and FE(OH)3 sol. All forms of lyophobic colloids require protective colloids to maintain their stability because they separate the agglomerates from the medium.
Protective Colloids Around Us
Have you ever imagined if the ice cream you eat melts quite profusely when you are chatting with fellows? It must be confusing. Your brain freezes instantly because the melted ice floods your hands, and it’s sticky enough. Meanwhile, you are not ready for it. The ice cream mixture should be able to remain stable at low temperatures because it has its flagship protective colloid. Gelatin makes the coagulation process in ice cream avoidable.
Gelatin is also added to the manufacture of gold sol so that the coagulation process doesn’t occur. The addition of electrolytes to the gold sol always causes coagulation. When there is gelatin, gelatin as a protective colloid will form a thin layer on the gold sol particles to protect them. There is also casein in milk.
This protein functions as an emulsion stabilizer so that milk can be enjoyed as it should. Meanwhile, in our body, there is also a protective colloid in the form of calcium phosphate in the blood plasma. Those of you who like to enjoy foods with margarine and mayonnaise also often find protective colloids in them that make these two food ingredients taste delicious, stable, and comfortable when eaten.
In addition to gelatin and other commonly used protective colloids, you can also take advantage of quality practical products and give them a good taste and safe as cellulose ether powder.
Protective Colloid and Your Growing Business
The clumping of the product you’re working on can be easily handled simply by adding a protective colloid—no need to think twice and be confused. You just need to coordinate with the employee on duty regarding the right formulation. Your production is high, and the protective colloid raw material is low? All you need to do is to contact the manufacturer that produces the stabilizing agent to order what you need. Don’t hesitate to do it because all the materials are safe, with international standards, and of course, quality assurance.
Find the protective colloid you need and other cellulose ethers for various industrial uses. There are ten thousand tons of China annual production has been used in various industries such as building materials, synthetic resins, agriculture, food, medicine, cosmetics, coating industrial, ceramic industry, textile, and many other industries.
