Whether underwear is clean or not has a great influence on the health of men and women, especially women. So there is a special laundry detergent for ladies' underwear. But its cleaning active ingredients are the same as ordinary laundry detergent.
Extended data
First, underwear laundry detergent is a special lotion made according to the unique efficacy of underwear. The working principle of underwear laundry detergent is the same as that of traditional washing powder. The effective component of underwear laundry detergent is surfactant, and most of them use nonionic surfactant. The PH value of underwear laundry detergent is close to neutral, which is mild to the skin. After discharged into nature, it degrades faster than washing powder, so it becomes a new generation of detergent.
Second, the effective component of underwear laundry detergent is mainly nonionic surfactant, and its structure includes hydrophilic end and lipophilic end, in which the lipophilic end combines with the stain, and then the stain is separated from the fabric through physical movement (such as hand rubbing and machine movement). At the same time, the surfactant reduces the tension of water, so that water can reach the surface of the fabric and make the effective components play a role.
