Tell us about your production challenge

Laundry detergents are currently on the rise due to increasing urbanization and the need for automation. The global market will reach $98,139.7 million by 2030 from $61,711.0 in 2020, influencing the demand for laundry detergent equipment. Unlike in Western countries, powdered detergents are more popular in Asia and China because they’re cheaper.

Laundry detergent equipment and key process

Producers of laundry detergents either use the dry mixing method, the agglomeration process, or the spray drying method to make laundry detergents. However, spray drying is the best method because it produces a lightweight, well-hydrated product that doesn’t cake. In this technique, a mixer combines the surfactant with a builder like sodium silicate to form a slurry that ages in an aging tank. They spray dry the mixture in a spray drying tower, filter it, modify it with enzymes, fragrances, and colors, and move it to a storage machine for packaging.

Factors to consider in the washing powder production line

When formulating the product in the washing powder making machine, it’s essential to pay attention to the pH of the washing powder to ensure it is compatible with the human skin and can clean effectively. The optimum pH range for laundry detergent is 9-10.5. Alkalinity converts insoluble fatty acids to soluble salts that wash away easily. Ingredients like surfactants are necessary ingredients in the production. They reduce the surface tension of hard water to prevent the formation of an insoluble precipitate that leaves visible deposits on fabrics and makes them unappealing.

The environmental impact of laundry detergents

Detergents contain some harmful chemicals such as nitrogen and phosphate. Nitrogen reacts with phosphorus in water to create nutrients that stimulate algae growth in freshwater. Algae then utilize the oxygen in the water in a process called eutrophication. Eventually, this depletion in oxygen damages the ecosystem.

In addition, surfactants reduce the surface tension of water and make it easier for waterways to absorb pollutants and pesticides. An effective solution is to feed materials from plant sources into laundry detergent equipment to produce eco-friendly alternatives. But the challenge with creating environmentally safe detergents is the high cost of production. Ingredients from plants are more expensive than their synthetic counterparts.

Are laundry detergent pods safe?

Laundry pods have become popular due to their convenience. They contain water-soluble polyvinyl alcohol and liquid cleaning agents in pods. Unlike regular laundry detergents, they are pre-measured to provide a consistent result.

Its production eliminates water, allowing the cleaning ingredients to remain stable for a long period. Laundry pods are a good laundry detergent option; however, the concern about laundry pods is how unsafe they can be for children, who could mistake them for candies. As part of the safety rules, producers have been advised to make them child-proof by using child-safe caps and making sure opening them requires both hands.
