Bacterial Nanocellulose toward Green Cosmetics: Recent Progresses and Challenges

In the skin care field, bacterial nanocellulose (BNC), a versatile polysaccharide produced by non-pathogenic acetic acid bacteria, has received increased attention as a promising candidate to replace synthetic polymers (e.g., nylon, polyethylene, polyacrylamides) commonly used in cosmetics. The applicability of BNC in cosmetics has been mainly investigated as a carrier of active ingredients or as a structuring agent of cosmetic formulations. However, with the sustainability issues that are underway in the highly innovative cosmetic industry and with the growth prospects for the market of bio-based products, a much more prominent role is envisioned for BNC in this field. Thus, this review provides a comprehensive overview of the most recent (last 5 years) and relevant developments and challenges in the research of BNC applied to cosmetic, aiming at inspiring future research to go beyond in the applicability of this exceptional biotechnological material in such a promising area.

Automated summary

Bacterial nanocellulose (BNC) is attracting increased attention in the skincare field as a versatile polysaccharide with potential to replace synthetic polymers. With sustainability concerns and growth in the bio-based product market, BNC is expected to play a more prominent role in cosmetics.
