Abstract
A multifunctional laundry detergent with long-lasting antibacterial and odor-removal properties was developed by incorporating deodorizing enzymes and antibacterial agents into the formulation.The product was systematically evaluated through long-lasting antibacterial testing,Moraxella osloensis inhibition assays,GC-FID deodorization analysis,towel deodorization testing,national standard stain-removal testing,scanning electron microscopy(SEM)observation,and stubborn stain removal performance assessments.The results demonstrated that the addition of the antibacterial agent HP-100 imparted long-lasting antibacterial activity,which increased with higher agent concentrations.Deodorizing enzymes effectively suppressed the growth of Moraxella osloensis,a key odor-causing microorganism.Both GC-FID analysis and towel deodorization tests confirmed significant odor-removal performance,with efficacy positively correlated with enzyme concentration.The detergent met the stain-removal requirements of the national standard GB/T 13174.SEM analysis revealed distinct differences in fabric fiber morphology before and after washing;post-wash fibers showed no detectable residues or contaminants and exhibited a uniform,clean surface structure.Furthermore,performance testing against 16 common stubborn stains demonstrated excellent removal efficacy.Notably,the synergistic interaction between the antibacterial agent and deodorizing enzymes enhanced odor-removal performance compared with enzyme-only formulations,enabling a reduction in enzyme dosage.This synergistic strategy lowers formulation costs,optimizes resource utilization,and provides mutual benefits for both manufacturers and consumers.关键词
