In the context of the accelerated transformation of the daily chemical industry towards high performance, low irritation and sustainability, nanocellulose, with its unique nanostructure and bio-based characteristics, is becoming the core material in the field of laundry beads to break through the limitations of traditional formulas. As a nanoscale functional material extracted from natural plant fibers, its diameter is only 5-30 nanometers and its specific surface area is as high as 200-500 m²/g. This characteristic gives it excellent rheological regulation, interface stability and active delivery capabilities, providing technical support for the concentration, functionalization and environmental protection of laundry beads. 1. Core performance advantages of nanocellulose 1. Green and environmentally friendly bio-based nanocellulose is completely degradable and of natural origin, in line with the global 'microplastic-free' policy and the 'Clean Beauty' trend. The carbon emissions during its production process are more than 60% lower than those of petroleum-based materials, and it can be completely decomposed in the soil within 60 days after being discarded.

With the rapid development of graphene in the fields of conductive materials, composite materials, energy devices and functional coatings, problems such as poor dispersion stability, easy agglomeration, and insufficient processability have gradually emerged in its practical applications. Nanocellulose, as a natural nanomaterial with wide sources, controllable structure and excellent performance, is becoming an important functional additive and structural material to solve the bottleneck of graphene application. 1. Structure and performance advantages of nanocellulose Nanocellulose usually includes cellulose nanofibers (CNF) and cellulose nanocrystals (CNC). Its diameter ranges from a few nanometers to tens of nanometers, and its length can reach micron level. It has the following significant characteristics: ultra-high specific surface area and aspect ratio, excellent mechanical enhancement ability, good aqueous phase dispersion, and functional groups such as carboxyl and hydroxyl groups can be introduced through surface modification. Renewable, biodegradable, and environmentally friendly. These characteristics make nanocellulose indispensable in graphene systems.
