In the research and development of daily skin care product formulas, a stable system and high-quality facial skin feel are the core competitiveness of the product. Traditional thickening and suspending additives commonly have problems such as stickiness, slippery residue, and dull skin when rubbed, making it difficult to achieve both formula stability and high-end feel. Nanjing Tianlu Nanotechnology Co., Ltd. self-developed high-performance nanocellulose (CNF). Relying on the microstructure advantages of nano-scale fibers, it optimizes the application feel of daily chemical systems from the root, solves the skin-feeling pain points of traditional additives, and becomes the core functional base material for high-end skin care and light luxury cleansing products. 1. Common skin feel pain points of traditional daily chemical additives. Currently, the mainstream thickening suspension raw materials on the market generally have obvious skin feel shortcomings in formula applications, which seriously affect the end product experience: 1. Sticky and sticky: after application, the surface layer has a thick glue feel and slow absorption, causing oily skin to feel stuffy, sticky to pillows and clothes; 2. False smoothness: the surface layer forms a closed film layer, which is smooth to touch but has a residual film feel, and is dry and tight after washing;

1. Industry Foreword: The dispersion problem of nanocellulose restricts the large-scale industrialization of the industry. Nanocellulose (CNF), as a green biomass nanomaterial that is currently the focus of development in the global new material field, relies on its ultra-high specific surface area, ultra-high aspect ratio, excellent mechanical strength, good biocompatibility, and complete biodegradability. It is widely used in high-end fields such as water-based coatings, fine chemicals, daily chemical gels, biomedicine, environmentally friendly packaging, and composite material reinforcement. As domestic green substitution and plastic reduction policies continue to advance, nanocellulose has gradually become a core new material that can replace traditional chemical thickeners, synthetic rheology additives, and plastic reinforced substrates. However, in the long-term industrial application process, traditional nanocellulose has common technical problems such as poor redispersibility, easy agglomeration, hard agglomeration, and difficulty in activation, which have become the biggest bottleneck restricting the implementation of the industry. During the dehydration, drying, and molding processes of conventional dry nanocellulose, a large number of hydroxyl groups appear on the surface of the fiber.

As the domestic dual-carbon strategy continues to advance and environmental protection control standards continue to upgrade, the coatings, fine chemicals, and polymer composite materials industries are ushering in a structural transformation from the 'traditional chemical system' to the 'green low-carbon system.' The shortcomings of traditional materials in terms of performance stability, weather resistance, and environmental protection indicators have gradually become apparent. The industry generally needs new base materials that are lighter, more stable, lower energy consumption, and recyclable as technological breakthroughs. In this context, nanocellulose based on natural biomass is becoming a key new material to help industrial upgrading. As a naturally derived nanofunctional material, nanocellulose combines environmental protection attributes with the excellent performance of nanomaterials, and can effectively make up for the performance deficiencies of traditional formula systems without increasing the burden on environmental protection. Nanjing Tianlu Nanotechnology Co., Ltd. has long been focusing on the process optimization and scenario application research of nanocellulose, and continues to promote the implementation of material technology, providing services for coatings, chemicals, composite materials and other industries.
