Description

Plant-source surfactant composition and application thereof in preparing mother-infant safe infant liquid laundry detergent Technical Field The invention belongs to the technical field of liquid laundry detergent, and particularly relates to a botanical surfactant composition and application thereof in preparing mother-infant safe infant liquid laundry detergent. Background The skin barrier of the infant is not yet developed completely, the stratum corneum is weak, and the resistance to external stimulus is far lower than that of an adult, so that the infant liquid laundry detergent for mother and infant needs to meet the requirements of extreme safety and targeted decontamination. In the existing infant liquid laundry detergent, some products still adopt petroleum-based surfactants, although the components have strong detergency, the components have poor biodegradability, the problems of red and swollen skin, allergy and the like of infants are easily caused after residues, and even if the products are marked with 'plant sources', the defects of insufficient detergency of single plant surfactants exist, exclusive stains such as milk stains, complementary food stains, stool stains and the like of infants are difficult to effectively remove, the stains contain complex components such as protein, fat, starch and the like, and common plant surfactants are difficult to thoroughly decompose.
