Liquid laundry detergentis a kind of neutral detergent, which is suitable for washing personal clothes such as baby clothes and underwear by hand. Most liquid laundry detergents use non-ionic surfactants, with a pH close to neutral. It is gentle on the skin, can dissolve quickly in water and is easy to rinse. Moreover, it degrades relatively fast after being discharged into the natural environment, so it has become a new generation of detergents.
Our technical department has been always committed to researching and developing better and more environmentally friendly laundry detergent products.
The following is an introduction to liquid laundry detergents that comply with EU standards and have antioxidant functions:
. EU Standards-related
The European Union has strict and multi-faceted standard requirements for detergents like laundry detergents:
Safety aspects
– Ingredient restrictions: Strict regulations are imposed on the chemical components that can be used in laundry detergents and their maximum allowable contents. Some substances that may pose potential hazards to human health, such as certain heavy metals (mercury, lead, cadmium, etc.), formaldehyde, and some surfactants with relatively strong irritancy, are restricted to extremely low levels or even prohibited from use. This is to ensure that during daily use, when the laundry detergent comes into contact with human skin, it will not cause adverse reactions such as allergies and irritations. Meanwhile, after being discharged into the environment, it will not cause significant harm to the ecological environment of soil and water bodies.
– Labeling requirements: Laundry detergent products are required to clearly and accurately label key information such as ingredients, usage instructions, precautions, and shelf life. For example, for ingredients that may cause allergies, clear reminders should be provided so that consumers can clearly understand the product characteristics and use the products safely and reasonably.
Environmental protection requirements
– Biodegradability: EU standards advocate that the components in laundry detergents should have good biodegradability, especially the main components like surfactants. This means that after entering the natural environment, these components can be decomposed into harmless small molecular substances through the action of microorganisms within a certain period of time, reducing long-term pollution to the environment. Some surfactants that are naturally sourced or easily degradable after modification are more favored, such as some non-ionic surfactants synthesized based on plant oils.
– Ecotoxicity testing: Laundry detergents need to pass relevant ecotoxicity tests to ensure that after being discharged into environments such as water bodies, they will not have obvious toxic effects on aquatic organisms (such as fish, algae, plankton, etc.), thus safeguarding the balance of the ecosystem.
. Antioxidant functions
Antioxidant components and principles
– Types of common antioxidants: Laundry detergents with antioxidant functions usually add some specific antioxidant components. Common ones include natural plant extracts, such as vitamin C, vitamin E and their derivatives. Vitamin C can capture free radicals generated during the oxidation process through its own reduction effect, preventing the free radicals from further triggering the oxidation chain reaction, thereby protecting clothing fibers from oxidative damage. Vitamin E is also an effective free radical scavenger. It can be embedded into the lipid structure of clothing fibers to stabilize the cell membrane structure and prevent the oxidation of components such as fats in the fibers, enabling the clothes to maintain better color and texture.
– Other chemical antioxidants: Besides natural components, there are also some synthetic antioxidants, such as certain phenolic compounds (such as butylhydroxyanisole, dibutylhydroxytoluene, etc., but the use of such components must strictly comply with relevant EU safety standards). They can provide hydrogen atoms to free radicals and interrupt the chain reaction of free radicals, thus playing an antioxidant role.
Effects on clothing
– Color protection: During daily wearing, washing and drying, clothes are easily affected by factors such as oxygen in the air and ultraviolet rays and undergo oxidative discoloration. Especially for some colored clothes, their colors will gradually become dull. Laundry detergents with antioxidant functions can form a “protective film” on the surface of clothing fibers during the washing process, reducing the damage of oxidation to pigments, enabling the clothes to maintain bright colors after multiple washes and prolonging the time of maintaining the aesthetics of the clothes.
– Fiber quality maintenance: For the clothing fibers themselves, the antioxidant function helps to prevent fiber aging and embrittlement. For example, for cotton clothes, after long-term oxidation, the fiber strength may decline and they may become easily damaged. This kind of laundry detergent can delay this process, enabling the clothes to maintain good flexibility and durability and improving the overall quality and service life of the clothes.
In conclusion, liquid laundry detergents that comply with EU standards and have antioxidant functions integrate high-standard safety and environmental protection requirements with the special protective functions for clothes, and are increasingly attracting the attention and favor of consumers.
We are especially produce and export the liquid laundry detergent with different formula to meet different requirements from customers, and could supply you OEM and ODM service.
