Abstract
To solve the challenges of multifunctional additives in laundry detergent,such as difficulty in balancing multiple properties,poor compatibility between anionic and cationic components,and high dosage requirements of softeners,this study investigated the application performance of methacrylic acid/vinylpyrrolidone(VP)copolymer as a multifunctional additive in laundry detergent.A basic laundry detergent formulation was constructed to evaluate the effects of different methacrylic acid/VP copolymer dosages on anti-redeposition,fluffiness and softness,and its stability under high and low temperature conditions was verified.The results showed that methacrylic acid/VP copolymer exhibits excellent compatibility with the laundry detergent system and maintains stability over a wide temperature range.At an additive dosage of 0.75%,the anti-redeposition effect was optimal,and the deposition ash value as low as 0.210%.When 1.00%methacrylic acid/VP copolymer was added,the stacked height of towels reached 20.3 cm,which is 13.4%higher than that of the blank group,and the uniformity of loop arrangement was remarkably improved.The sensory score for softness was 42 points,which is superior to that of the commercial comparative polymers.Methacrylic acid/VP copolymer synergistically enhances anti-redeposition,fluffiness,and softness through a single additive,which simplifies the detergent formulation process and provides a new solution for the development of high-performance and multifunctional laundry care products.关键词
