​Functional additives are substances added to food, cosmetics, pharmaceuticals, plastics, paints, and other products to alter their physical, chemical, texture, taste, aroma, and color characteristics.

​In today’s world, manufacturers and formulators are constantly seeking ways to improve the performance, durability, and cost-effectiveness of their products. One crucial way this is achieved is through the use of functional additives.

The key lies in disrupting the stability of the foam. Foam a phenomenon formed by the dispersion of gas in a liquid and being wrapped by a liquid film, while defoamers can efficiently penetrate into the interior of these foam films. They reduce the surface tension of the film or enhance the local viscosity of the film, causing the foam to become fragile and prone to disintegration.

Cationic surfactants are surface-active substances that dissociate to release positive charges in an aqueous solution. The hydrophobic groups of this type of substances are similar to those of anionic surfactants. The hydrophilic groups of such substances mainly contain nitrogen atoms, and there are also atoms such as phosphorus, sulfur, and iodine. The hydrophilic groups and hydrophobic groups can be directly connected, or they can be connected through ester, ether, or amide bonds. Among them, the most widely used are nitrogen-containing amine salts.

Anionic surfactants are a class of surfactants characterized by their negatively charged hydrophilic (water-attracting) head. This negative charge enables them to effectively remove dirt and oils from surfaces, making them indispensable in various cleaning and industrial applications. Their ability to generate foam and emulsify oils has led to their widespread use in products ranging from household detergents to industrial cleaners.

Polyethylene Glycol (PEG) is one of the most versatile and widely used compounds in modern industrial and pharmaceutical applications. As a polyether compound with multiple molecular weights and characteristics, PEG has gained global attention across industries like pharmaceuticals, cosmetics, personal care, food processing, chemical manufacturing, and healthcare. Its adaptability, chemical stability, and solubility make it an essential material in hundreds of formulations and manufacturing processes.
