Dishwashing liquid formulation plays an important role in the performance and cleaning efficiency of this widely used product. Since dishwashing liquid is an essential household cleaning product and plays an important role in maintaining kitchen cleanliness and hygiene, the right formulation can easily remove grease, stains, and stubborn food residues. In this comprehensive guide, we examine various aspects of dishwashing liquid formulation; from the primary role of water as a universal solvent and the key cleaning performance of surfactants such as SLS and SLES, to the importance of chelating agents in dealing with hard water and well-known brands, as well as environmentally friendly solutions designed for modern kitchens.
The history of dishwashing liquid dates back to the early twentieth century, when the first synthetic detergents were developed. Since then, the formulation of these products has continuously evolved to provide greater efficiency, improved safety, and better environmental compatibility. Today, various types of dishwashing liquids are available on the market, each offering specific benefits.
Key Ingredients in an Effective and Functional Dishwashing Liquid Formulation:
In dishwashing liquid formulation, many effective ingredients are used, each with its own specific function and performance. Below, we introduce the key active ingredients used in dishwashing liquid formulation.
Water as the Main Ingredient in Dishwashing Liquid Formulation:
Water is the main ingredient in dishwashing liquid. It is known as the “universal solvent” because it can dissolve a greater variety of substances than almost any other liquid. Water alone is considered a good cleaning agent, but when combined with detergents and surfactants, it becomes a highly powerful and effective dishwashing liquid.

Solvents for Removing Grease in Dishwashing Liquid Formulation:
Solvents help dissolve grease and loosen stubborn stains. Ethanol and Isopropyl Alcohol are common solvents that improve cleaning performance.
Surfactants for Effective Cleaning:
Common surfactants used in dishwashing liquid formulations include Sodium Lauryl Sulfate (SLS), Sodium Laureth Sulfate (SLES), Cocamidopropyl Betaine, Soyamid, Coconut Fatty Acid Diethanol Amide, and Alkyl Polyglucoside. Alongside these ingredients, Sodium Xylene Sulfonate can be used as a highly effective sulfonated hydrotrope. Since hydrotropes increase the solubility of sparingly soluble organic materials in water, Sodium Xylene Sulfonate helps keep active cleaning ingredients well dispersed and effective even in complex formulations. As a result, products containing OXONIL SXS are clearer, more stable, and provide better performance.
Thickeners and Rheology Modifiers in Dishwashing Liquid Formulation
- Sodium Chloride: Commonly known as table salt, it is used to increase the viscosity of dishwashing liquid.
- Hydroxypropyl Methylcellulose (HPMC): A cellulose-based viscosity-enhancing agent that helps control the viscosity and uniformity of dishwashing liquid.
- Xanthan Gum: A natural viscosity enhancer obtained through the fermentation of sugars that provides the product with a smooth and stable texture.
Chelating Agents (Chelating Agents)
Chelating agents such as Ethylenediaminetetraacetic Acid (EDTA) and Diethylene Triamine Penta(Methylene Phosphonic Acid) (7-Na) (DTPMP – 7Na) work by binding to metal ions present in hard water. This process reduces the formation of soap deposits and improves cleaning efficiency. As a result, the formation of films and residues on dishes and glassware is prevented, leaving them shiny and completely clean.
Preservatives for Extending Product Shelf Life
To maintain product performance over time, preservatives are added to prevent the growth of bacteria and fungi. These preservatives prevent microbial growth and maintain the quality and effectiveness of the product. One of the common preservatives used in dishwashing liquid formulations is Methylisothiazolinone (MIT).
Conditioning Agents and Skin Care
Ingredients such as Glycerin or Polyquaternium-7 can be used in dishwashing liquid formulations to create a mild and skin-friendly product. These additives help moisturize and soothe the skin of the hands and reduce the risk of dryness or irritation caused by frequent use.
Enzymes in Dishwashing Liquid Formulation
Enzymes such as proteases, amylases, and lipases are biological catalysts that help break down food particles, proteins, starches, and fats, respectively. Adding these enzymes to dishwashing liquid formulations increases the cleaning power of the product and enables more effective removal of stubborn stains and food residues.
Fragrances
Fragrances or essential oils can be added to dishwashing liquid to create a pleasant scent and improve the user’s sensory experience. The use of a variety of fragrances makes it possible to appeal to different preferences, such as citrus, floral, or herbal fragrances.
Colors and Pigments
Adding color to dishwashing liquid increases its visual appeal and attracts attention on store shelves, helping differentiate the product from competitors. Color can also indicate the type of fragrance or a specific formulation; for example, green for herbal fragrances or blue for sea-inspired fragrances.
Considerations Regarding pH, Temperature, and Stability of Dishwashing Liquid Formulation
To achieve optimal performance and stability, formulators should maintain the pH of dishwashing liquid between 7 and 9 and store the product at room temperature.
Health and Environmental Considerations
When using any cleaning product, it is essential to consider its impact on human health and the environment. Fortunately, most reputable dishwashing liquid manufacturers are aware of these concerns and strive to produce products that are safe for consumers and environmentally compatible.
Summary:
Dishwashing liquid, as an essential product for kitchen hygiene, has evolved into a complex combination of specialized chemical ingredients to provide improved efficiency and safety. An effective formulation is based on water as the primary solvent and includes key ingredients: surfactants such as SLS and SLES for removing grease, solvents such as ethanol for dissolving stains, and hydrotropes such as Sodium Xylene Sulfonate for improving the stability and performance of cleaning agents. In addition, additives such as thickeners including salt and Xanthan Gum, chelating agents such as EDTA for dealing with hard water, preservatives for extending shelf life, and enzymes for breaking down food residues all contribute to the final performance of the product.
Modern manufacturers, in addition to maintaining appropriate pH and product stability, also pay attention to skin-conditioning agents such as Glycerin and environmental considerations in order to provide consumers with a product that is safe, environmentally compatible, and appealing in terms of its visual appearance and pleasant fragrance.
