Let's see if yellow toilet paper is absolutely healthy. The truly retro yellow toilet paper is made of straw, straw, reed, weeds and other original ecological materials. Because of the high lignin content in unbleached pulp, the paper feels hard and has low flexibility, and the paper is not skin-friendly. Therefore, it is necessary to add more softener and wet strength agent for softening to enhance water absorption and softness. Compared with white toilet paper, this kind of paper is not only unhealthy and environmentally friendly, but also irritating to the skin after long-term use. In addition, in order to meet the needs of the public, some black-hearted businesses dyed white toilet paper yellow and played the banner of "pure natural". This shows that yellow toilet paper is not absolutely healthy.
So is bleached white toilet paper harmful to human body? According to China's regulations, it is safe to reasonably bleach and add recycled materials and fluorescent agents in toilet paper such as roll paper and toilet paper, as long as it does not exceed the standard. So white toilet paper is not necessarily harmful. Toilet paper that meets national standards is healthy and good paper, and can't be judged by color alone.
So how to judge whether a tissue is good or not? Teach you a few tricks: see the place, feel the hand, be more resilient, and see the result of firing. Formal and good toilet paper, factory name, address and hygiene license number are essential on its packaging; Soft and delicate feel, no hair loss and no powder loss; A little hard pull will not break; After burning, it is white ashes.
In addition, don't buy rough and stiff bulk toilet paper for the sake of cheapness. Because this unpackaged toilet paper has not been disinfected, it is easy to be contaminated by bacteria.
