The invention relates to the technical field of daily chemicals, in particular to a color-protecting
laundry detergent containing
plant extracts and a preparation method of the color-protecting
laundry detergent. The color-protecting
laundry detergent is prepared from the following components in percentage by
mass: 12.5 to 18.3 percent of natural anionic surfactant, 6.4 to 9.7 percent of
nonionic surfactant, 3.2 to 5.8 percent of
plant polyphenol extract, 3.0 to 5.2 percent of
fiber affinity natural
polymer, 2.1 to 4.0 percent of bio-based chelating aid, 1.8 to 3.5 percent of natural
glycoside synergist, 0.9 to 2.3 percent of
pH buffering agent, 0.6 to 1.4 percent of
antioxidant plant essential oil and the balance of deionized water. The compound
protease comprises
alkaline protease,
neutral protease and
papain; the invention aims to solve the technical problems that the existing
laundry detergent is poor in color protection effect, insufficient in
environmental protection performance and large in damage to fabrics, and provides a
laundry detergent product which takes natural plant extracts as core components and has an efficient color protection function.
