The invention belongs to the technical field of
laundry detergents, and particularly relates to a
plant-derived surfactant composition and application thereof in preparation of a mother-and-infant-level safe infant
laundry detergent. The preparation method of the
plant-derived surfactant composition comprises the following steps: (1) weighing the raw materials; (2) crushing tea
saponin and soapnut
saponin raw materials, respectively adding deionized water, soaking, and filtering; (3) adding the rest deionized water into the reaction kettle, starting stirring, adding coco-
glucoside, and stirring; sequentially adding the tea
saponin extracting solution and the soapnut saponin extracting solution into the reaction kettle, keeping the temperature unchanged, and stirring; and (4) continuing to add the licorice extract, continuing to stir, then adding
citric acid, and uniformly stirring to obtain the
plant-derived surfactant composition. The plant-derived surfactant composition disclosed by the invention is pure in component, and can be used for accurately and efficiently decomposing and removing special milk stains,
complementary food stains and other complex stains for babies.
