As the dual-carbon policy continues to be implemented, plastic restriction regulations continue to tighten, and the global industrial chain is accelerating away from dependence on petroleum-based raw materials, safe, renewable, and fully degradable new bio-based materials have become an urgent need for the transformation and upgrading of all walks of life. Many formulation engineers and material manufacturers are looking for functional fillers that can take into account performance, safety and environmental protection. Nanocellulose ( CNF ) is the natural nanobiomass material with the fastest commercialization speed and the most abundant application scenarios.
Nanocellulose is extracted from natural plant fibers such as bamboo, wood, cotton linters, agricultural and forestry straw, etc. It relies on green processes such as mechanical dissociation, enzymatic pretreatment, and modification control to disassemble macro fibers to the nanometer scale. Different from ordinary cellulose derivatives, it retains the natural cellulose skeleton structure and does not rely on the synthesis of petrochemical raw materials. The production process is low-pollution, and the finished product is non-toxic and non-irritating. It can be completely biodegraded in the natural environment after disposal and does not produce microplastic residues. It perfectly meets the compliance requirements of clean beauty, food contact, degradable packaging and other tracks. As downstream customers' demands for low-carbon certification, environmental labels, and sustainable supply chains continue to rise, nanocellulose is transforming from a new laboratory material into a core functional additive that can be industrialized for mass production and can be stably supplied.
The mainstream of nanocellulose in the industry is divided into three major categories: cellulose nanofibrils ( CNF ), cellulose nanocrystals ( CNC ), and bacterial cellulose ( BC ). At present, for domestic industrialization, mass supply, and adaptation to formula modification needs CNF is the main category , and it is also the category that Nanjing Tianlu Nanotechnology focuses on R&D and production.
The diameter of nanofibers can reach tens to hundreds of nanometers, and they have ultra-high specific surface area. The fiber surface is rich in a large number of active hydroxyl groups. This is its core advantage that distinguishes it from traditional thickeners and reinforcing fillers. We can carry out directional surface modifications such as hydrophilic, hydrophobic, and amphoteric based on customer system needs, and adapt to different system compatibility such as aqueous phase and weak polarity to reduce agglomeration and improve dispersion stability.
From the perspective of material properties, nanocellulose is light, high-strength, has excellent tensile properties, and has multiple composite functions: excellent film-forming barrier properties, thixotropic thickening and suspension capabilities, good biocompatibility, and low thermal expansion coefficient. Compared with traditional HPMC 、CMC , Carbo and other thickening systems, CNF thickening is non-sticky, has stronger salt resistance and stability, and is not easily interfered by electrolytes and surfactants in the formula. Compared with glass fiber and inorganic powder reinforcing fillers, it has a lower density and will not significantly increase the weight of the product after addition. It also improves toughness and reduces the risk of brittle cracking of the material.
In cosmetics and care formulations, nanocellulose is used as a natural suspension stabilizer, skin feel regulator, and film feel auxiliary. Many cleansing, essence, and suspension-type stock solution formulas have long faced the pain points of delamination, precipitation, and dilution after standing. Using nanocellulose can build a three-dimensional network colloidal structure, stabilize pearlescent particles, plant extracts, and frosted particles, and maintain the system's long-term uniformity. At the same time, it brings a refreshing and light skin feel, avoiding the problems of traditional thickeners that stick to the face and rub masks. It is suitable for shower gel, shampoo, essence milk, facial mask, suspended essence, makeup remover products, etc. The raw materials comply with the safety regulations for cosmetic raw materials and support the development of Clean Beauty and natural and organic products.
Food-grade nanocellulose can be used as food suspension stabilizer, dietary fiber additive, and edible film-forming substrate. In protein drinks, fruit and vegetable juices, plant milk, and cocoa coffee suspension systems, it inhibits particle settlement and reduces the types of stabilizer compounds; as a fresh-keeping coating substrate, it can form a dense oxygen barrier film on the surface of fruits, vegetables, and fresh food, delaying water loss and oxidative deterioration, and extending the shelf life. The product can meet food contact grade standards, is safe and has no odor, and is suitable for beverages, baking, fresh-keeping film, etc.
In papermaking, paper-based packaging, and fully degradable film systems, nanocellulose is an efficient reinforcing additive. Adding it to paper pulp can improve the dry strength, wet strength and tear strength of paper, increase the retention rate of fine fibers and fillers, and reduce the consumption of additives. It can be used in degradable films and paper-plastic composite coatings to improve oxygen and grease barrier properties and help paper packaging replace disposable plastics. It is an important material in paper-to-plastic transformation, express packaging, and food packaging plastic reduction solutions.
Water-based coatings, industrial inks, and water-based adhesive systems commonly suffer from sagging, pigment settling, and insufficient coating weather resistance. After adding nanocellulose, it relies on thixotropic properties to achieve anti-sag and anti-settling, and improve pigment dispersion stability; after curing to form a film, it improves the density, wear resistance and cracking resistance of the paint film, and is suitable for water-based industrial paints, wood paints, printing inks, water-based white glue and other scenarios.
In the field of new energy, it can be used to reinforce separator coatings and electrode slurries to improve the dimensional stability of substrates; in the biomedical direction, relying on good biocompatibility, it can be used as a substrate for wound dressings, tissue scaffolds, and drug sustained-release carriers; 3D it can regulate rheological properties in printing slurries to ensure molding accuracy; in rubber and plastic composite materials, it can be used as a lightweight reinforcing filler to replace some inorganic powders and chopped fibers, and is used in low-carbon home appliances and lightweight components.
Although nanocellulose has outstanding advantages, many purchasers often encounter several common problems during the sample stage: difficulty in powder dispersion and agglomeration when entering water; poor modification matching, demulsification and viscosity reduction after adding to the formula; large fluctuations in viscosity and rheological indexes in different batches, making it impossible to stabilize mass production; small supply volume and unstable delivery time, only small trial proofing is possible, and it is difficult to scale up industrialization. These are also the key bottlenecks that restrict the large-scale implementation of nanocellulose. The performance of simple laboratory samples is good, but it is easy to overturn when put into continuous production on the production line. This places high demands on the process control, modification customization, and supporting technical services of raw material manufacturers.
Nanjing Tianlu Nanotechnology focuses on the stable mass production and directional modification services of nanocellulose CNF . Relying on its own process system, it continues to optimize the entire process of pretreatment, homogeneous dissociation, and modification control, and specifically solves industry pain points such as poor dispersion, limited compatibility, and batch fluctuations.

We provide stable and industrialized nanocellulose solutions to upstream and downstream enterprises in daily chemicals, food, packaging, coatings, new energy, composite materials, etc., and work with partners to create a sustainable new material supply chain.
Under the global trend of plastic reduction and low-carbon development, the bio-based materials track has maintained rapid growth. Nanocellulose, as a platform material with both functional and environmentally friendly attributes, continues to unleash market demand. As the preparation process continues to iterate and costs gradually decline, downstream application scenarios will continue to penetrate from high-end niche tracks to general industrial materials. In the future, nanocellulose will continue to make breakthroughs in the direction of replacing more plastics, lightweight manufacturing, and green formulations, helping all walks of life to reduce carbon and plastic, and build a low-carbon, circular, and sustainable new material industry ecosystem.
