新型多糖基二元流变改性剂在香精油微胶囊悬浮中的应用与性能
Application and performance evaluation of novel polysaccharide-based binary rheological modifier in the suspension of perfume oil microcapsules
摘要
Abstract
In the modern personal care industry,the pursuit of"multiple benefits in one wash"has led to the incorporation of functional solid particles,such as microcapsules,into detergents.However,due to the density difference between the particles and the matrix,maintaining a uniform suspension of these particles poses a challenge,which can diminish their functional efficacy.To address this issue,this study utilized a composite binary rheological modification system comprising hydroxypropyl methylcellulose(HPMC)and TEMPO-oxidized bacterial cellulose microgels(T-BC-microgel)to stabilize the suspension of perfume oil microcapsules.This research systematically investigated the impact of varying concentrations of suspending agents on the stability of perfume oil microcapsules and bubbles in different matrices.The findings demonstrated that the HPMC/T-BC-microgel composite system significantly improved the suspension stability of perfume oil microcapsules and bubbles in both commercial laundry detergents and water.At a concentration of 0.048%suspending agent,the perfume oil microcapsules remained stably suspended for up to 240 days without altering the original rheological properties of the detergent.Additionally,the study uncovered an interaction between the suspending agents and surfactants that further enhanced the suspension effect.Based on these findings,this research offered a new pathway for developing efficient,stable and environmentally friendly suspension systems with potential industrial applications.关键词
