In large-scale industrial dishwashing operations, there are various thickening agents or additives that can be used to increase the viscosity or thickness of dishwashing liquid. These additives help improve the clinginess and effectiveness of the detergent, allowing it to adhere to surfaces and enhance its cleaning properties. Here are a few common thickening agents used in industrial dishwashing liquids:
Sodium chloride (salt): Adding salt to the dishwashing liquid can increase its viscosity. Salt thickens the liquid by interfering with the movement of water molecules, making the detergent thicker and more gel-like.
Sodium polyacrylate: This polymer is commonly used as a thickening agent in many cleaning products. It absorbs water and swells, creating a thicker consistency. Sodium polyacrylate is effective in increasing the viscosity of dishwashing liquid.
Cellulose derivatives: Certain cellulose derivatives, such as carboxymethyl cellulose (CMC), can be used as thickening agents. These derivatives have high water-absorbing properties and can form a gel-like structure when dissolved in water, providing a thicker texture to the dishwashing liquid.
Xanthan gum: Xanthan gum is a natural thickening agent derived from bacteria. It forms a gel-like substance when combined with water and can be used to increase the viscosity of dishwashing liquids.
Alginates: Alginates are extracted from seaweed and are commonly used as thickeners in various industries, including cleaning products. They can enhance the thickness and stability of dishwashing liquids.
It's important to note that these thickening agents are primarily used in commercial or industrial settings and may not be suitable for household dishwashing liquids. They are typically incorporated during the manufacturing process to achieve the desired viscosity and texture for industrial applications.
