In the context of rapid iteration of the green daily chemical and pure beauty industries, natural biomass functional raw materials have become the core breakthrough for the upgrading of daily chemical formulas. Traditional daily chemical formulas are highly dependent on synthetic additives such as acrylics, carbomers, and cellulose derivatives. Although these raw materials can achieve basic functions such as thickening, suspension, and film formation, they generally have shortcomings such as poor system tolerance, sticky skin, easy sensitization, and poor biodegradability. They are difficult to adapt to the current industry development needs for safety, efficacy, and low carbonization. Nanocellulose, as a nanoscale polymer material derived from plant biomass, relies on its unique one-dimensional nanostructure, controllable rheological properties, excellent biocompatibility and environmental friendliness. It can optimize the daily chemical product system from multiple dimensions such as formula stability, skin feel, efficacy utilization, and green attributes. It is currently the new daily chemical functional substrate with the most application potential. This article takes the formulation and application technology mechanism of nanocellulose as the core, from the perspective of structural characteristics, core

With the deep integration of pure beauty, functional beauty and light luxury beauty, the market has set higher standards for the formula texture, usage experience and efficacy stability of smear-on facial masks and innovative functional masks. Many current mainstream facial mask products generally rely on traditional synthetic thickening stabilizers such as carbomer and xanthan gum. They have long-term formula shortcomings that are difficult to avoid: the transparent system is easy to become cloudy, and functional particles such as natural petals, essence beads, and plant scrubs are easy to settle and stratify, making the product attractive. At a discount; at the same time, traditional colloids are sticky and thick, have poor breathability, make the skin stuffy on the face, are easy to rub mud, and leave a sticky feeling. Moreover, the moisturizing only stays on the surface for instant hydration, and the water-locking endurance is insufficient. It cannot meet the four core needs of high-definition texture, refreshing skin feel, long-lasting moisturizing, and stable effects. Aiming at the pain points of industry formulations, nanocellulose (CNF) derived from natural plants has become a new generation to replace traditional chemical colloids with its unique nano-three-dimensional network structure and excellent thixotropic rheological properties.

Under the industry wave of pure beauty, functional skin care, and sustainable consumption, the daily chemical industry is bidding farewell to traditional chemical raw materials and is moving towards a comprehensive iteration in the direction of natural safety, minimalist formula, high efficacy, and green biodegradability. The raw materials commonly used in traditional daily chemicals, such as synthetic thickeners, petroleum-based emulsifiers, plastic microbeads, and chemical film-forming resins, commonly have pain points such as high allergy risk, sticky skin feel, poor environmental compliance, and weak formula stability. It is difficult to meet the current high-end skin care needs of consumers and global plastic restrictions and ESG compliance standards. As a new pure natural biomass material derived from plants and microorganisms, nanocellulose has broken through the performance bottleneck of traditional daily chemical raw materials and has become a core innovative raw material in the field of cosmetics and care by virtue of its unique nano-scale three-dimensional network structure, excellent biocompatibility and multi-functional formula adaptability. At present, the nanocellulose used in mainstream applications is divided into three categories: plant nanofibrils (CNF), nanocellulose crystals
