——A green functional raw materials that take into account both natural, safe and high-performance

1. Introduction to nanocellulose

Nanocellulose ( Nanocellulose ) is a nano-scale structural fiber extracted from natural cellulose materials (such as wood, cotton, bamboo or bacteria). It mainly includes three forms: cellulose nanocrystals ( CNC ) , cellulose nanofibers ( CNF ) and bacterial cellulose ( BC ) . Its diameter is usually between 5 and 100 nanometers and can reach several microns in length, with extremely high specific surface area, mechanical strength and excellent biocompatibility.

In the development of functional cosmetic formulas, nanocellulose gradually replaces some traditional synthetic thickeners and film-forming agents with its natural source, safety, low sensitivity, and strong degradability , and has become an important raw material to promote the upgrading of green cosmetics.

2. The core functions and advantages of nanocellulose in cosmetics

1. Natural and efficient thickeners and rheology regulators

Nanocellulose can form a stable three-dimensional network structure in water, giving the formula good viscoelastic and tactile adjustment properties . Its high shear dilution properties allow the paste to flow smoothly during extrusion and application, and return to its original state after use, effectively preventing the formulation from being layered and sagging.

2. Excellent film formation and water locking performance

Nanocellulose can form a colorless, transparent, breathable natural protective film on the surface of the skin , which has good skin-friendliness and smoothness. It can be used to enhance the moisturizing and barrier functions of facial masks, essences, sprays and other products, and extend the skin moisture retention time.

3. Sustained release carrier as active ingredient

With its mesh nanostructure, nanocellulose can load commonly used active substances such as vitamin C , nicotinamide, hyaluronic acid, etc., delay the release rate, improve stability and absorption efficiency , and show great potential in high-end functional skin care products.

4. Soothing and repairing effects

Research shows that nanocellulose has a certain anti-irritating effect on sensitive skin , which can reduce the redness, swelling, dryness and itchy reaction after skin barrier damage, and is suitable for sub-sectors such as soothing, sensitive skin, and infant skin care.

5. Sustainability and green environmental protection

Nanocellulose has a wide range of sources, is renewable and completely biodegradable. It not only meets the cosmetics industry's demand for 'Clean Label' but also reduces the long-term impact on the environment. It is the preferred solution to achieve a green transformation of formulas.

3. Typical product application direction

Product Type	Application functions	Technical Advantages
Facial mask products	As a film cloth, thicken the essence, and enhance the film formation	Lightweight, breathable, skin-friendly, moisturizing and water-locking
Lotion /cream/paste products	Improve system stability, optimize skin feel, and provide controlled release structure	Natural soft, safe and non-irritating, stable consistency
Soothing and repairing skin care products	Anti-inflammatory relief, relieve stimulation response, and promote barrier repair	Suitable for sensitive skin, high biocompatible
Gel /element/spray	Transparent thickening, moisturizing and water-locking, improving skin feeling and absorption effect	Non-stick, superior rheology regulation performance, no residue
Functional skin care products	Active substances are loaded and controlled release, and improve the stability and permeability of effective components	Improve bioavailability and extend the time of action

4. Future development trends

As consumers' attention to ingredients safety, product efficacy and environmental protection responsibilities continues to rise, the cosmetics industry is transforming from the traditional distribution direction ' naturalization + functionalization ' . As an important raw material for fusion of these two, nanocellulose can not only give the product a better sensory experience and stability, but also create a green, technological and sustainable high-end image for the brand.

In the future, with the help of surface modification, composite technology and intelligent formula design, nanocellulose will further expand its application potential in the fields of functional skin care such as anti-aging, whitening, sun protection, makeup removal and cleaning .
