Cause diarrhea, weight loss, spleen atrophy, liver cirrhosis, etc. Therefore, you can only use it with confidence if you choose qualified products. The laundry powder produced according to our country's standards is usually marked with two performance signs: numbers and texts on the package: the numbers and model signs that indicate the performance. main determinant.

In terms of appearance, the high-quality washing powder of the brand is divided into hollow granules similar to millet grains. The bag is fluffy and full, the hand-touching bag has a smooth feeling, the color is pure, and the particles are evenly distributed; the fake and inferior washing powder is mixed with coarse particles or hard agglomerates. The back of the bag is dissatisfied, the gap of the bag is large, the bag feels stagnant and astringent when touched, and the powder color is gray-yellow. If the color of the added enzyme is gray-blue, the enzyme activity has expired, or it is other dyed substances. In terms of use, high-quality washing powder dissolves quickly in water, the solution does not burn when you touch it, the solution is clear and smooth, the amount of foaming is large, the detergency is obvious, the amount of washing is small, the washing efficiency is obvious, and the smell is not pungent.
