烷基糖苷类烷氧基化产品的漂色工艺开发及性能评测OA

Alkoxylated alkyl polyglucosides(APG-NF)were prepared by alkoxylation of alkyl polyglucosides(APGs).While retaining the excellent properties of conventional APGs,APG-NF exhibits low foaming characteristics and excellent low-temperature fluidity.The effects of APG-NF content,bleaching temperature,bleaching time,hydrogen peroxide(H₂O₂)dosage,pH,and storage time on the bleaching performance of APG-NF were investigated.The results showed that the optimal bleaching conditions were an APG-NF content of 60%,H2O2 dosage of 5%,pH 9.5,bleaching temperature of 60 ℃,bleaching time of 20 min,and storage time of 28 days.Under these conditions,the color of the final product was below 110 Hazen.The application performance of APG-NF was evaluated and compared with that of conventional APG0810.The results indicated that APG-NF exhibited extremely low foaming properties and generated almost no foam.The wetting performance and removal of sebum and carbon black of APG-NF were lower than those of APG0810,whereas its emulsification performance toward soybean oil and liquid paraffin was superior to that of APG0810.These findings demonstrate that APG-NF significantly reduces foaming while maintaining favorable surface-active properties.
