Natural and biodegradable, efficient and stable, and green material solutions for skin feeling enhancement
As people's requirements for environmental protection, safety and skin experience of daily chemical products continue to improve, natural and high-performance functional additives are gradually replacing traditional petrochemical raw materials. Nanocellulose , as a green and renewable multifunctional material, is increasingly widely used in shower gel formulas due to its excellent suspension, rheology, film-forming and biocompatibility , and has become a hot topic of research and industrialization that has attracted attention from the industry .
Nanocellulose is to extract cellulose from plant fibers or bacterial fermentation, and then refine its microstructure to the nanoscale (the diameter is generally 5–50 nm and the length can reach hundreds of nanometers) through high shear, chemical modification or enzymatic decomposition , forming the following three types of forms:
type | Main sources | Structural features | Applicable scenarios |
CNF (cellulose nanofiber) | Plant sources such as wood pulp and straw | Long fibrous, network structure | Thickening, moisturizing, suspending |
CNC (cellulose nanocrystals) | Acid-lyzed natural cellulose | Rigid nanorod-like structure | Strengthening membrane, controlled release carrier |
BC (Bacterial Cellulose) | Microorganisms such as acetate | Three-dimensional gel-like, high-purity, impurities-free | Medical dressings, high-end skin care products carriers |
These structures impart the following properties of nanocellulose that are highly valuable in daily chemical products:
Extremely strong thickening and rheology regulation ability : form a three-dimensional network structure that can control the viscosity of the shower gel and give ideal fluidity;
Excellent suspension stability : It can evenly disperse essential oil beads, plant particles, microcapsules, etc. to prevent precipitation and stratification;
Natural source, gentle and non-irritating : non-toxic to the skin and mucous membranes, especially suitable for sensitive skin;
Excellent moisturizing and film-forming ability : form a breathable protective film on the surface of the skin, locking water and moisturizing, soft and comfortable;
Green and environmentally friendly, biodegradable : in line with the trend of sustainable development of daily chemical products.
In actual product development, nanocellulose is not only used as a structural and functional additive , but also plays a key role in improving product texture and improving user experience.
Nanocellulose has a high hydration capability and network structure, and can significantly improve the system viscosity at low concentrations (such as 0.2%~0.5% ), showing excellent shear thinning characteristics, easy to extrude when used, and not easy to flow after use, improving the advanced sense and ease of use of the product. It is often used to replace synthetic thickeners such as carbomer and xanthan gum.
In shower gels containing pearlescent particles, flavor beads, herbal particles, and capsule-type active substances, the three-dimensional network of nanocellulose can stably wrap these components, making them evenly distributed in the system, without sedimentation or stratification for a long time, greatly improving appearance stability and sensory effects.
Nanocellulose forms a transparent hydrogel film on the surface of the skin, which is not tight or dry after washing. It is especially suitable for use with mild surfactants such as amino acids and APG , improving the dryness caused by traditional cleaning ingredients, and enhancing the gentleness of the product and skin care effects.
Nanocellulose is completely derived from plants, is degradable, has no petrochemical residues, and is more friendly to the skin and the environment. Using this type of additive will help the product obtain certifications such as ' natural formulas ', ' green and low-carbon ', 'ECOCERT', ' microplastics ' , and enhance the brand's environmentally friendly image.
In standard shower gel formula, nanocellulose concentration is recommended to be 0.1% to 0.5% (based on dry matter), and its form can be hydrogel, slurry or powder dispersion. The addition method is recommended as follows:
Sequence : It can be added after dilution of the surfactant phase, and it is recommended to add it to the aqueous phase for high-speed dispersion;
Compatibility : It has good compatibility with AES 、APG and betaine surfactants, but coagulation may occur under strong acid and alkali conditions, so the pH should be maintained at 5–8.；
Avoid wall hanging phenomenon : It is recommended to use appropriate cosolvents or structural regulators (such as glycerol, propylene glycol) to improve the uniformity of wall hanging and film formation.
As consumers continue to favor natural, low-irritating, green and environmentally friendly products, the application of nanocellulose in shower gels and other toilet products will become increasingly mature. In the future, it will be combined with hyaluronic acid, ceramide, plant extracts, etc., and is expected to be used to develop multi-functional daily chemical products such as anti-allergic, oil control, and antibacterial, becoming one of the key materials in the field of cleansing and skin care.
Nanjing Tianlu Nano Technology Co., Ltd. is a national high-tech enterprise focusing on the research and development, production and application development of nanocellulose. The company has a complete TEMPO oxidation method, enzymatic method and mechanical method preparation process , and can provide nanocellulose products with different particle sizes and concentrations from scientific research to industrial grade.
