What Are the Functions of Detergents?

[EdenLynn]

In ancient societies, there were no detergents, so some grease and stains could not be thoroughly removed. However, with the advancement of technology today, detergents have become a powerful tool for people to solve stubborn grease and dirt problems. Therefore, today, we will focus on detergents to explain their functions and the precautions for using them. 1. Functions of Detergents Detergents have excellent wetting, penetrating, dispersing, emulsifying, as well as foaming and defoaming properties. As a result, detergents are widely used for cleaning purposes. They can remove grease from dishes, pots, and utensils, clean pesticides from the surfaces of fruits and vegetables, and even dissolve and disperse some harmful substances, making them a highly effective cleaning agent. 2. Precautions for Using Detergents 1. Because detergents have strong stain-removing and antibacterial functions, some people tend to use excessive amounts when washing dishes or cleaning fruits and vegetables. However, this is not advisable. Some detergents contain additives that may leave residues on tableware or food. If not rinsed off completely, these residues can enter the human body along with the items, causing potential harm. 2. To ensure detergents are thoroughly rinsed off, it is best to use clean running water rather than water in a basin. The water pressure from a faucet helps wash away the detergent more effectively. 3. When rinsing off detergents, it is recommended to use warm or hot water, as cold water may cause grease that has been broken down by the detergent to re-coagulate on the dishes, reducing the cleaning effect. The above covers the functions of detergents and the precautions for their use. We hope you can learn some practical tips and methods for using detergents and gain a deeper understanding of them.

Every day when I do housework at home, I use detergent. When washing clothes, it can completely break down sweat stains and grease stains, even the yellow stains on the collar of white T-shirts can be cleaned; when the sink is full of greasy dishes, just squeeze two drops of dish soap, and the foam instantly wraps around the grease, washing it all away. The stubborn grease stains accumulated on the kitchen stove can be sprayed with cleaner, left for five minutes, and then wiped with a cloth to make it shine like new. The limescale on the bathroom faucet and soap scum in the bathtub can be restored to shine immediately after wiping with specialized detergent. Even children's toys covered in mud can be cleaned by soaking them in a bit of laundry detergent and scrubbing a few times. However, the amount used needs to be careful—don't pour too much when washing clothes, as residual foam can make the skin itchy. Nowadays, many detergents are labeled as biodegradable, making them safer to use.

Modern life heavily relies on detergents, but we must face their environmental costs. Phosphorus-containing detergents discharged into rivers and lakes can trigger algal blooms, depleting oxygen and causing fish deaths. Fluorescent brighteners are difficult to degrade in nature, eventually accumulating in the soil. I specifically choose plant-derived eco-friendly products with biodegradable labels on the bottles—though more expensive, they're worth it. Usage habits also matter: opting for concentrated formulas in machine washing reduces consumption, and avoiding direct foam runoff into storm drains during car washes is crucial. Every time I see chemical foam floating in rivers, it reinforces my commitment to eco-friendly products—after all, clean clothes and clean water shouldn't be mutually exclusive choices.

As someone with a chemistry background, let me explain how detergents work. The key lies in surfactant molecules, which have a hydrophilic (water-loving) head and a lipophilic (oil-loving) tail. They encapsulate stains and are then rinsed away by water flow. Oily dirt is broken down through emulsification, while protein-based stains are tackled by proteases that sever molecular chains. In hard water areas, chelating agents like sodium citrate are added to bind calcium and magnesium ions, preventing scale formation. Thickeners help the liquid adhere longer, and sodium percarbonate-based bleach specifically targets pigment deposits. However, be cautious as highly alkaline detergents can corrode metal surfaces, and down jackets require neutral pH formulas.

Compared to the days of using soapberry powder and washboards twenty years ago, detergents have truly revolutionized life. Grandma said when she was young, she had to crush soapnuts and soak them in water, spending half a day just to wash clothes. After laundry detergent became popular in the 1970s, laundry time was reduced by two-thirds. Nowadays, detergents are even more specialized: wool-specific detergents protect fibers, baby laundry liquids have non-irritating formulas, and floor cleaners include anti-slip ingredients. I remember in the 1990s when dishwashing liquid first became trendy, my mom always complained about the difficulty of rinsing off the foam, but now the improved formulas make rinsing much easier. Every time I use a pump-bottle laundry detergent, I marvel at how technological progress has made household chores so much easier.

Detergent has far more uses than just laundry and dishes. I use it weekly to clean my car's interior: a neutral detergent diluted with water gently cleans leather seats without damaging the surface, while brake dust on the wheels dissolves instantly with a spray of degreaser. Adding a couple of drops of dish soap to water when cleaning windows prevents streaks and fogging. Garden tools covered in rust? Soaking them in laundry detergent for half an hour makes them look brand new. Even hardened paintbrushes can be restored to their original bristle texture with detergent. However, it's crucial to choose the right product for the task—hand soap with moisturizers is gentle on skin, while car wash solutions should be wax-free to avoid harming the paint. Versatile doesn’t mean universal—proper usage is key.
