How to tell if the washing powder you bought is a fake or shoddy product?

First, distinguish from the packaging. Brand-name high-quality washing powder, the packaging bags are clearly printed, no wrong version and ink pollution; fake brand-name washing powder, most of the packaging is of poor printing quality, with wrong version and ink pollution. Second, distinguish from appearance. Brand-name high-quality washing powder, the powder is 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. Dissatisfied, the bag has a large gap, the hand feels obscure when touching the bag, and the pink 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. Finally, distinguish from use. Brand-name high-quality washing powder, dissolves quickly in water, does not burn when you touch the solution, 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. The counterfeit and inferior washing powder dissolves slowly in water, the aqueous solution is turbid, there are sediments on the bottom of the basin, the solution feels burning when touched by hand, the amount of foam is very small, and the detergency is poor. Pungent alkaline odor.
