——Homologous materials, different scales, different application values ​​Against the background of the continuous development of green materials and bio-based functional materials, cellulose-derived materials are widely used in fields such as daily chemicals, pesticides, coatings, medicines and composite materials. Among them, nanocellulose and microcrystalline cellulose (MCC) are two types of materials with a high degree of industrialization at present. Although the two are derived from natural cellulose, they are essentially different in structural scale, performance and application direction. This article will systematically compare nanocellulose and microcrystalline cellulose from the perspective of structure, performance and application, providing a reference for material selection. 1. The sources of raw materials are the same, but the structural processing methods are different. Both nanocellulose and microcrystalline cellulose use natural plant cellulose as raw materials, such as wood pulp, cotton pulp, etc., but their preparation ideas are completely different: microcrystalline cellulose mainly removes amorphous elements from cellulose through acid hydrolysis.

1. What is nanocellulose? Nanocellulose is a nanoscale material prepared from natural cellulose through physical, chemical or biological methods. The typical size ranges from a few nanometers to tens of nanometers, and the length can reach micron level. Depending on the structure and preparation method, common types include cellulose nanofibers (CNF), cellulose nanocrystals (CNC) and bacterial cellulose (BC). As a natural polymer material that is widely sourced, renewable and biodegradable, nanocellulose not only has environmentally friendly properties, but also exhibits excellent mechanical properties and functional designability. It is considered an important representative of the new generation of green functional materials. 2. Core performance advantages of nanocellulose 1. Ultra-high mechanical strength and toughness Nanocellulose has extremely high specific strength and specific modulus, and the theoretical strength of a single fiber can be close to the level of steel. In composite systems, the resistance of materials can be significantly improved

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.
