– Laundry sheets: Usually adopt highly efficient concentrated surfactants and pay attention to the combination of surfactants. To achieve good decontamination effects within a small volume, anionic surfactants and non-ionic surfactants are rationally combined. For example, some advanced laundry sheets use high-quality non-ionic surfactants such as fatty alcohol polyoxyethylene ethers, which have stable decontamination performance in low temperature and hard water. Moreover, the content of surfactants in laundry sheets is relatively high, enabling them to achieve good decontamination effects with a smaller amount.
– Traditional washing powders: The main ingredient is also surfactants, but the content of surfactants in washing powders is relatively low. The anionic surfactants in them may mainly be sodium alkyl benzene sulfonate. Although this component has a strong decontamination ability, in some environments with hard water, it is prone to combine with calcium and magnesium ions in water to form precipitates, thus reducing the decontamination effect. In addition, the activity of surfactants in washing powders may decrease in a low-temperature environment, affecting the washing quality.
– Traditional laundry detergents: The content of surfactants in laundry detergents is generally between that of laundry sheets and washing powders. It also combines multiple surfactants. However, laundry detergents pay more attention to the mildness and solubility of the product. They usually contain more non-ionic surfactants, such as polyoxyethylene ethers, which make them have better solubility in water and cause relatively less damage to clothing fibers. But in some cases, such as when encountering high-concentration grease stains, their decontamination ability may not be as good as that of laundry sheets.
In terms of builders
– Laundry sheets: The amount of builders used is relatively small because laundry sheets are concentrated products. Some laundry sheets will add some new types of builders, such as sodium silicate with anti-redeposition and buffering functions. These builders are mainly to prevent stains from reattaching to clothes and ensure the stability of the washing process.
– Traditional washing powders: They contain more builders, such as sodium tripolyphosphate (in some phosphorus-containing washing powders) and sodium carbonate. Sodium tripolyphosphate is an excellent builder. It can chelate calcium and magnesium ions in water, soften the water quality and improve the decontamination efficiency of surfactants. However, the extensive use of phosphorus-containing washing powders can lead to eutrophication of water bodies and have an adverse impact on the environment. Sodium carbonate mainly increases the alkalinity of the washing liquid and enhances the decontamination ability, but if used improperly, it may damage clothes.
– Traditional laundry detergents: The content of builders is relatively small, mainly including some components for adjusting pH values and preventing redeposition. For example, some laundry detergents will add citric acid to adjust the acidity and alkalinity to make them milder, and there will also be a small amount of anti-redeposition agents to ensure the washing effect.
In terms of enzyme preparations
– Laundry sheets: The application of enzyme preparations in laundry sheets is becoming more and more widespread. Laundry sheets usually add specific enzymes such as protease, amylase, and lipase according to their main target markets and stain types. These enzyme preparations can effectively decompose the corresponding types of stains. And due to the relatively refined production process of laundry sheets, the storage conditions of enzyme preparations are better, which can ensure the activity of enzymes to a certain extent.
– Traditional washing powders: Some traditional washing powders also contain enzyme preparations. However, due to the granular structure and production process of washing powders, enzyme preparations may be affected to some extent during storage, resulting in a decrease in activity. Moreover, when adding enzyme preparations to washing powders, their stability needs to be considered because the alkaline environment and other components of washing powders may react with enzymes and affect the effect of enzymes.
– Traditional laundry detergents: Similar to laundry sheets, laundry detergents also add enzyme preparations to enhance the decontamination ability. However, the liquid environment of laundry detergents has higher requirements for the stability of enzyme preparations, and some stabilizers need to be added to ensure the activity of enzymes during storage and use.
In terms of whitening agents and fragrances
– Laundry sheets: Some laundry sheets will add fluorescent whitening agents to improve the whiteness and glossiness of clothes, and the amount and types of fragrances added are also relatively rich. Due to the production process of laundry sheets, which can achieve good ingredient mixing, fragrances can be evenly distributed in the laundry sheets and can give clothes a good fragrance during the washing process.
– Traditional washing powders: Traditional washing powders also add whitening agents and fragrances. However, during the production process, since they are granular products, the distribution of whitening agents and fragrances may not be uniform. Moreover, the fragrances in some washing powders may volatilize during storage, affecting the final use effect.
– Traditional laundry detergents: Laundry detergents usually also add whitening agents and fragrances. Since they are liquid products, the distribution of whitening agents and fragrances is relatively uniform. Meanwhile, laundry detergents pay more attention to the lasting fragrance when choosing fragrances because consumers have higher expectations for the fragrance retention effect of laundry detergents.
