Nanocellulose: a new generation of green and efficient thickening rheology regulator

In many fields such as coatings and daily chemicals, food processing, biomedicine, and industrial slurries, the stability, adaptability and safety of the thickening system directly determines product quality and user experience. Traditional thickeners such as polyacrylates, cellulose ethers, and xanthan gum commonly have pain points such as high addition amounts, easy delamination and sedimentation, high temperature instability, sticky residue, and poor environmental protection. They are difficult to meet the current development needs of lightweight, long-term stability, and green safety for high-end products.

As a new bio-based nanomaterial derived from natural plants, nanocellulose breaks through the technical bottleneck of traditional thickening materials and becomes a core new material that replaces traditional thickeners and rheological agents with its unique nanofiber structure, excellent rheological control performance, and 100% degradable environmental protection properties. Nanjing Tianlu Nanotechnology Co., Ltd. is based in the technological innovation highland of Nanjing. It is a high-tech enterprise deeply engaged in the industrialization of nanocellulose in China. It focuses on the research and development, large-scale production and scenario-based application solution output of high-performance nanocellulose. It relies on independent core processes to overcome industry application pain points and create a full-category, highly adaptable green thickening material system to help upgrade the performance of high-end formula systems in many industries.

1. Core thickening mechanism: precise rheological control of three-dimensional nanonetworks

The excellent thickening and stabilizing effects of nanocellulose are due to its unique physical structure and molecular mechanism of action. It does not need to rely on chemical modification. It can achieve multiple effects of efficient thickening, stable suspension, and adjustable rheology through purely physical effects. The core mechanism of action is divided into three major dimensions:

The first is the tangle thickening of the three-dimensional network . Nanocellulose has an ultra-long nanofiber morphology and an extremely large specific surface. In aqueous systems, it can spontaneously build a continuous, uniform, and elastic three-dimensional nanonetwork structure through intermolecular hydrogen bonding and mechanical entanglement. This network can bind a large number of free water molecules, greatly increase the zero-shear viscosity of the system, and achieve significant thickening effects with very low addition amounts, completely solving the problems of high addition and high thickness of traditional thickeners.

The second is the stabilization and synergy of electrostatic and steric hindrance . The surface of modified nanocellulose has a uniform charge, which can disperse particles in the system through electrostatic repulsion. At the same time, relying on the steric hindrance effect of nanofibers, it effectively blocks the agglomeration and sedimentation of particles such as powders, essential oils, and microcapsules, giving the system a stable yield stress and achieving a long-lasting suspension anti-stratification effect.

Finally, there is the reversible thixotropic rheological properties . This is the core advantage that distinguishes nanocellulose from traditional thickeners. When the system is left standing without shear, the nano-network structure is completely formed, and the system has high viscosity and strong stability. When subjected to shear forces such as stirring, smearing, and pumping, the three-dimensional network quickly stretches and orients, the system viscosity drops significantly, and the fluidity and ductility are significantly improved. After the shear force is removed, the network structure can be quickly reconstructed independently, and the viscosity is quickly restored, achieving intelligent rheological control of ' static thickening and dynamic thinning ' .

Compared with traditional thickeners, the nanocellulose thickening system combines high efficiency, stability, safety and adaptability with outstanding core advantages and perfectly meets the iteration needs of high-end products. Nanjing Tianlu Nano is deeply engaged in the field of biomass nanomaterials. Relying on independent core processes such as low-damage biomass stripping and precise nanostructure control, it effectively solves industry problems such as poor dispersion of ordinary nanocellulose on the market, weak system adaptation, and easy turbidity of transparent systems. The product performance far exceeds conventional similar materials and can fully meet the refined and high-quality formulation production needs of various industries.

Compared with traditional thickeners, the nanocellulose thickening system has high efficiency, stability, safety and adaptability. It has outstanding core advantages and adapts to the iteration needs of high-end products:

1. Ultra-low addition, efficient thickening . Conventional systems only require an addition of 0.1%-0.6% to achieve the thickening and stabilizing effect of several times the amount of traditional thickeners, significantly reducing formula costs, reducing additive residues, making the product texture purer, and effectively avoiding the disadvantages of thick and sticky traditional colloids.

2. Temperature-resistant and salt-resistant, stable performance 。Nanocellulose relies on the physical network structure to thicken and is not greatly affected by high temperature, acid, alkali, and electrolyte salts. It can maintain stable viscosity in a wide temperature and wide pH range without problems such as high-temperature thinning, low-temperature agglomeration, salt precipitation and stratification, and is suitable for complex industrial production and multi-formulation systems.

3. Natural, safe, green and environmentally friendly . The raw materials are derived from natural plant fibers such as wood, straw, cotton and linen, and are prepared through physical processing. They have no chemical residues, are non-toxic and harmless, have excellent biocompatibility, are completely naturally degradable, and have no environmental burden. They are in line with the safety standards and dual-carbon environmental protection trends in the fields of food, maternal and infant, high-end daily chemicals, and medicine.

4. Long-term locking and stable, not easy to fail . The formed nano-three-dimensional network structure is extremely stable and can lock moisture, active ingredients and solid particles in the system for a long time, effectively inhibiting settlement, stratification, agglomeration and water separation problems, significantly extending product shelf life and improving product storage stability.

5. Wide adaptability and strong compatibility . It is compatible with most water-based systems such as water-based coatings, emulsions, gels, slurries, food slurries, etc. It does not react with active ingredients and additives in the formula, does not affect the original efficacy, color and smell of the product, and is suitable for formula optimization and upgrading in many industries.

Stably suspends scrub particles, plant extract particles, and essential oil microcapsules under static conditions to prevent stratification and sedimentation; it shears and thins when applied, and the texture is light and smooth, without a sticky muddy feeling. At the same time, it can form a breathable protective film to enhance skin feel and product texture.

2. Coating and ink industry .
