Nanocellulose ( CNF , cellulose nanofibrils) is a nanoscale natural fiber material extracted from wood pulp and agricultural and forestry biomass. It is a biodegradable and environmentally friendly nanomaterial. With its high specific surface area, high strength, excellent rheological thickening, suspension stability, film-forming barrier and other characteristics, nanocellulose is replacing some petrochemical raw materials and becoming a popular green functional additive in daily chemicals, food, papermaking, coatings, composite materials, biomedicine and other fields. Nanjing Tianlu Nanotechnology is deeply involved in the industrialization of nanocellulose and can provide standardized products and customized carboxylation modification solutions to support the docking of samples and technology.
Nanocellulose is a one-dimensional nanofiber material prepared from natural cellulose through mechanical dissociation, chemical modification and other processes. It is mainly divided into three categories:
1. CNF cellulose nanofibrils: long fiber network structure, outstanding rheology, thickening, and suspension capabilities, and is also the most widely used category on the market;
2. CNC cellulose nanocrystals: short crystal form, stronger rigidity, suitable for material reinforcement;
3. Bacterial cellulose BC : biosynthesized, high purity, mostly used in medical and wound dressings.
We mainly promote carboxylated modified nanocellulose ( CCNF ), which improves water dispersibility and compatibility on the basis of ordinary CNF , is not easy to agglomerate, and is suitable for the development of aqueous system formulations.
· The raw materials are renewable, completely biodegradable, low-carbon and environmentally friendly, in line with the green material policy direction;
· The fiber diameter is nanoscale, the specific surface area is large, and it has excellent suspension, thickening and thixotropic effects;
· Good film-forming properties, dense film, and good oxygen barrier properties;
· High mechanical strength, adding a small amount can improve the tensile and tear resistance properties of the base material;
· No odor, low irritation, can be used in scenes with high safety requirements such as food contact, daily chemical care, etc.
Nanocellulose serves as a natural thickening and suspending agent, replacing part of carbamide and xanthan gum. It is used as the base material for petal shower gel, essence spray, lotion, and facial mask. It can stabilize the system and prevent powder from settling, leaving the skin feeling refreshed. It also has a moisturizing and film-forming effect. It is a popular green raw material in current care formulas.
As a food-grade stabilizer and suspension aid, it can be used in coffee, protein drinks, jams, and plant drinks to solve the problem of solid particle stratification and sedimentation; it can also be used in edible barrier films to extend the food preservation cycle.
Adding a small amount can improve paper strength, uniformity, and printability; it can be used in degradable packaging coatings to form a high barrier film, reduce oxygen transmission rate, and help upgrade plastic-free packaging and degradable packaging.
Used as a rheology additive in water-based coatings and water-based inks to prevent sagging and thickening; blended with PLA, 、PVA , etc. to prepare bio-based composite materials to improve the toughness and impact resistance of the substrate, and can be used in disposable products, films, and plates.
Cutting-edge directions such as water treatment membranes, biomedical dressings, sensor substrates, and energy storage diaphragms can all be developed based on modified nanocellulose.
Native nanocellulose is difficult to disperse and prone to agglomeration. We use TEMPO oxidation + high-pressure homogenization process to controllably introduce carboxyl groups to obtain carboxylated nanocellulose that is dispersed and stable. Modified nanocellulose: ✅ Evenly dispersed in water, no obvious agglomeration ✅ Better compatibility with water-based resins, polysaccharides, and powders ✅ Stronger storage stability, not easy to stratify
The carboxyl content, solid content, and fiber size can be adjusted according to customer needs, and special models can be customized to suit the formula.

A : Xanthan gum and carbohydrate are traditional synthetic / microbial polysaccharide thickeners; nanocellulose has a fiber network structure with different thixotropic properties and stronger suspension ability. It also has film-forming and reinforcing properties. It is a biomass green raw material and is suitable for pursuing clean label and degradable formulas.
A : Unmodified native CNF is easy to agglomerate; the dispersion of carboxylated modified nanocellulose is greatly improved, and the stability is good in normal aqueous system. We will provide customers with dispersion process suggestions.
A : Depending on the scenario, the addition range varies greatly: papermaking reinforcement is at a few thousandths level; daily chemical suspension and food suspension are generally in the range of 0.1%-1% ; composite material reinforcement can be adjusted as needed.
A : We have food contact grade nanocellulose models that can be used in food-related applications. We provide corresponding compliance information and can explain the usage scenarios in advance before placing an order.
As the market demand for green, low-carbon, degradable materials continues to grow, nanocellulose, as a biomass nanomaterial with natural origin and diverse properties, continues to open up market space. Nanjing Tianlu Nano continues to iterate on nanocellulose preparation and modification technology, providing stable and cost-effective CNF raw materials and supporting technical services for daily chemical, food, packaging, and new material companies, and jointly promoting the upgrading of the green materials industry.
