ẢNH HƯỞNG CỦA MỘT SỐ THÀNH PHẦN ĐẾN ĐỘ ỔN ĐỊNH CỦA DUNG DỊCH NƯỚC RỬA TAY CHỨA GEL LÔ HỘI

Tóm tắt

Handwashing liquid is the primary defense against microbial diseases including COVID-19. Producing
environmental-friendly ones, which means less impact on the ecosystem, is much appreciated. This
study investigated the effect of ingredients on the stability of handwashing liquid containing aloe vera
gel to provide a scientific basis for the production of environmental-friendly ones. The results show that
gel extracted directly from aloe vera leaves was not suitable to ensure the stability of handwashing
liquid. Eco-friendly surfactant cocamidopropyl betaine had almost no effect on the stability of
handwashing liquid with commercial aloe vera gel of up to 35% in 2 hours but recognizable effect after
48 hours. The supplemented thickener, carbomer, at a rate of up to 0.5% did not affect the stability of
the handwashing liquid when CAPB content was less than 5%
