Research on the application of nanocellulose in skin care cream formulation

Nanocellulose has been gaining the attention of researchers for last 10 years, especially in the application in the cosmetics industry.Nanocellulose is a highly biocompatible and environmentally friendly material with a market value of 416 million USD in 2022 and is expected to reach 1.3 billion USD in 2030.Vietnam has a diverse and abundant source of lignocellulose that can be used to produce nanocellulose on a large scale.Nanocellulose was created by Research group from the School of Chemistry and Life Sciences, Hanoi University of Science and Technology from sulfate pulp has fibril form (Cellulose Nanofibril -CNF) with the fiber diameter less than 100nm and the fiber length of microns.This study is the first time that evaluated the applicability of the above CNF in supporting the texture of the cream formulation such as emulsification, thickening and dispersion.In addition, some activities such as moisturizing, moisture lock, skin adhesion and sensory evaluation were also evaluated.The results showed that nanocellulose at a concentration of 5 -15% had a good combination with the emulsifier ceteareth-25 at a concentration of 5 -10% and carbomer at a concentration of 1.0 -1.5%.The cream formulation had good oil-in-water homogenization, stable texture and are promising to be applied in cosmetic and pharmaceutical cream.
