Foods taken for nutrition have a significant impact on people's health. Therefore, it is the most important rule that food producing enterprises comply with the cleaning rules. The basic materials for cleaning are detergents and disinfectants.

Detergent, which is an effective cleaning aid, is a synthetically produced chemical substance used to remove impurities. Detergents break down dirt with the help of the chemicals in its formulas and make them float in water. Soils may be inorganic in nature such as metal, salt and lime residues, or may be organic in protein, such as yogurt or blood, carbohydrate in sugar and starch, or fat in animal and vegetable oils.

The surfactants contained in the detergents are dispersed in water and encircle the soil. In this way, dirt becomes floatable and is removed from the surface with water. Factors affecting cleanliness are: the amount of dirt, the density of the chemical in the detergent content, the hardness and temperature of the water, the time of application of the detergent and a number of mechanical influences.

Detergents are obtained from petrochemical products and are generally used in processes such as cleaning and purification. Detergents are in powder, liquid or gel form. Generally, dishwashing detergents and salts and descaling agents used in washing machines are included in the powder detergent group. Dishwashing detergents, liquid soaps, fabric softeners, descalers, soil solvents, degreasers, bleaches and bleaches are included in the liquid detergent group. Gels or creams are surface active products and do not use excess oil. Generally used in dish washing and washing machines.

Meaning detergent is dirt remover. In practice, all cleaners other than soaps are classified as detergents. From a chemical point of view, there are many chemicals, each with a separate cleaning task. However, the most negative aspect of detergents is that they cannot be broken down by microorganisms. Therefore, it creates more environmental pollution in soap.

Scope of Cleaning and Detergent Testing

The cleansing effects of detergents are based on their ability to weaken the bonds between water molecules and to reduce surface tension of water. This is called surface activity. Thanks to surface active agents, dirty materials to be washed are more easily wetted by water.

Many tests are carried out by authorized laboratories in various production stages of detergents. The main tests are:

  • Physical and chemical analysis, anionic active substance determination, cationic active substance determination, nonionic active substance determination, total active substance determination, soap analysis, sodium carbonate determination, sodium tripolyphosphate determination, zeolite determination, EDTA determination, sodium sulfate determination, silicate determination, determination of sodium perborate, determination of sodium percarbonate, determination of active oxygen, determination of TAED, determination of active chlorine, determination of hydroxide, determination of sodium hypochlorite, determination of optical bleach, physical examination, determination of pH, density determination, viscosity determination, total acidity determination , determination of free acidity and alkalinity, determination of water insoluble matter and moisture determination.
  • Microbiological analyzes include total aerobic mesophilic bacteria count, total coliform count and total yeast and mold count.
  • Bactericidal activity tests include hygienic hand rubbing and bactericidal activity tests of hand washing agents.

When performing these tests in the authorized laboratories, firstly the legal regulations in force are followed and the standards published by the domestic and foreign organizations are taken into consideration. The following are a few standards that are based on this measurement and testing:

  • TS ISO 2271 Surfactants - Detergents - Determination of anionic active substance by two-phase titration by manual or mechanical means
  • TS EN ISO 2870 Surfactants - Detergents - Determination of hydrolysable and non-hydrolyzable anionic active substances under acidic conditions
  • Surface active substances - Detergents - Determination of the content of cationic active substance - Part 2871: High molecular mass cationic active substance
  • TS EN ISO 2871-2 Surfactants - Detergents - Determination of cationic active ingredient content - Part 2: Low molecular mass (between 200 and 500) cationic active substance
  • TS 5155 Laundry detergent - used in industrial washing machines
  • TS 13773 Dishwashing detergent - Industrial
  • TS 518 Synthetic detergents
  • TS ISO 4325 Soaps and detergents - Determination of EDTA content - Titrimetric method
  • TS 5606 Surfactants - Detergents - Determination of acidic hydrolysis resistant anionic active ingredient (trace amounts)
  • TS 5607 Surfactants - Detergents - Hydrolysable anionic active substances under alkaline conditions - Determination of hydrolysable and non-hydrolysable anionic active substances
  • TS 6370 Surfactants - Powder detergents - Determination of apparent density - Volume and mass measurement method
  • TS 6542 Powder detergents - Determination of total phosphorus (v) oxide content Gravimetric method with quinoline phosphomolybdate
  • TS 9560 Surfactants - Guide to comparative testing of laundry detergents performance

The detergent industry is one of the major competitive markets all over the world. There are many large and multinational companies in this market. At the same time, the number of domestic enterprises is quite high. It is not easy to compete in such a market. The most important issue here is customer satisfaction. Without this, it is not possible to compete. The image of a product affects whether the consumer will buy it again. The image that consumers want to create depends largely on the qualities of the product. At this point the importance of detergent tests emerges. From the raw material entry until the product is presented to the consumer, the quality and reliability of the detergent tests, which cover all production stages and from the final tests to determine the characteristics of the final product, also create confidence in the consumers.
