1. The advantage of phosphorus-free laundry detergent is that it is environmentally friendly, as it does not contain phosphorus, so it will not pollute the water quality and marine farming enterprises. In addition, phosphorus-free laundry detergent is less harmful to the skin. However, the washing effect of phosphorus-free laundry detergent is not as good as that of phosphorus laundry detergent, especially when dealing with grease and protein stains, which require several washes to achieve the cleaning effect.

2. The advantage of phosphorous laundry detergent is that it has a better washing effect, especially for different types of stains such as oil, protein and fiber stains. This is because phosphorus enhances the washing power of laundry detergent. However, there are some problems with phosphorous laundry detergent, and its large-scale use can pollute the environment and adversely affect the quality of water bodies, leading to eutrophication of lakes, rivers and other waters and affecting the balance of the water ecosystem.
