1. Overview of Nanocellulose Materials Nanocellulose (Nanocellulose) is a type of nanoscale material prepared from natural cellulose through physical, chemical or enzymatic treatment. It mainly includes cellulose nanofibers (CNF) and cellulose nanocrystals (CNC). This material has the following typical characteristics: high specific surface area and high mechanical strength, excellent film-forming properties and network structure, good biocompatibility and degradability, and can be functionally controlled through surface modification. In the context of green materials and sustainable development, nanocellulose has become one of the important research and application directions in the field of new materials. 2. Overview of the main application fields of nanocellulose. At present, nanocellulose has been used to varying degrees in many industries, including: the main application areas are packaging materials, oxygen and water barrier, enhanced mechanical properties, rheological control of coatings and inks, anti-settlement, suspension stability of daily chemical products, and thixotropic regulation of biocompatibility of medical materials.

1. Overview of Nanocellulose Nanocellulose (Nanocellulose) is a nanoscale material obtained by mechanical or chemical dissociation of natural cellulose, mainly including cellulose nanofibers (CNF) and cellulose nanocrystals (CNC). It has high specific surface area, high aspect ratio and excellent rheological control ability, and has broad application prospects in the field of functional materials. In recent years, with the development of the concept of green materials, nanocellulose has gradually been used as a functional additive in daily chemical formulation systems, especially in suspension systems. 2. Industry Pain Points of Daily Chemical Suspension Systems In washing and care products (such as shower gel, shampoo, scrub, etc.), it is often necessary to add the following components: anti-dandruff particles, fragrance microcapsules, functional active particles, but these particles often have the following problems: 1. Easy to settle. The difference in stratified density causes the particles to sink quickly to the bottom, affecting the appearance and stability of the product. 2. The viscosity of the system is unstable.

1. What is bacterial cellulose? Bacterial Cellulose (BC) is a natural polymer material synthesized by microbial fermentation. Compared with plant-derived cellulose, it does not contain lignin and hemicellulose, has higher purity, and has a nanoscale three-dimensional network structure, high crystallinity and excellent mechanical properties. With these properties, bacterial cellulose has become one of the important research hotspots in the field of biomedical materials in recent years. 2. The core advantages of bacterial cellulose in medical dressings 1. It has both high water retention and breathability. The moisture content of bacterial cellulose can be as high as 99%, which can form a stable moist environment on the wound surface and has good gas exchange capabilities, which is helpful to accelerate wound healing. Keywords: Moist healing, medical dressing materials, bacterial cellulose moisturizing properties 2. Excellent biocompatibility, its source is natural, its structure is pure, it is non-toxic and non-irritating to the human body, and it can effectively reduce inflammatory reactions
