Microfibrils suspended structure
A continuous microfibril network for liquid oral-care systems
NatFibra® OL is based on NatFibra® fiber from fermentation sources. Fibres are dispersed and interwoven in the liquid phase, providing structural support for particles and droplets.
System viscosity, mobility and oral use are affected by the complete formulation and should be determined in combination with product additions, particle characteristics and processing conditions.

02 / Material Structure NatFibra® fiber
20-40 nm microfibrils form a continuous network in the liquid phase
NatFibra® fiber is fermented from sugar sources and cellulose molecular chains are connected by glucose units via β-1,4 glycosidic bond and further assembled as nanofibrils. Higher spect rateo allows material to form more contact points in aqueous case.
Droplet distribution
Improve the spatial distribution of fragrance microdrops or other dispersed droplets in successive aqueous cases.
Low shear structure
Establish internal structures and retain the flow status required for liquid systems.
03 / Preparation process Fermentation and Purification
Fermentation, purification and application formulation
Fragmentation, effective solid content and final product composition are based on current product specifications.
- 01
Fermentation
Sugar sources and germs enter the fermentation stage, forming the bio-cellulose.
- 02
Purification
Elimination of cultures and fermentation residues and acquisition of pure cellulose material.
- 03
Application formulation
Material formation based on the use requirements of the dental care liquid system.
- 04
Quality control
Complete formulation, quality indicator recognition and packaging.
04 / Sample observation Particle Distribution
The distribution of particles depends on the network structure and the condition of the formation
The particles in the left sample are concentrated mainly at the bottom of the container; the particles in the right sample are distributed in the liquid phase. The group did not include basic additions, particle properties, storage temperature and observation time.
The official certification shall be based on the stability of the particle density, particle size, shape and addition, and shall not directly consider the state in the photograph as the result of the shelf period.
Scope of evaluationParticle distribution, sedimentation at the bottom, gathering, dispersing.
05 / adaptation Mobility and compatibility
Evaluate flow behavior and formulation compatibility together
The structural effects of the material are not the only mechanism based on the traditional high viscosity, but do not mean that the viscosity of all of it remains unchanged. The practical application window is confirmed by a gradient test.
pH
Recognition of appearance, particle distribution, viscosity, yield condition and storage stability.
electrolyte
Comparison of network structures, particle deposition and liquid droplets before and after salt addition.
Temperature
Observe the appearance and current state of the heat, high temperatures, low temperatures and high cryogenic cycles.
Shear
Validation of the impact of decentralized speed and time on network recovery and the homogeneity of finished products.
Formulation components
Assess the compatibility of perfumes, surfactants, preservatives, sweets and functional components.
It is recommended to record the flows and continuity of Brookefield viscosity, yield condition, touch recovery, flow curves, and during dumping, pumping or ejection.
06 / Water Holding Structure Water combined with free water
Hydroxyl groups, pores and the continuous network influence water distribution
Hydroxyl radicals on cellulose chains form hydrogen keys with water molecules. The pore and continuous network between microfibrils together influence the distribution of water in materials in combination with free water.
98%bio-cellulose materials with maximum water retention
>100 ×Material holding data in the cited study
The above values correspond to the bio-cellulose material and the corresponding research conditions and are not equivalent to the conclusion of oral wetting or efficacy of the finished NatFibra® OL product.
07 / Dispersion Model Pickering Dairy Model
Microfibrils contribute to the oil-water interface and continuous aqueous structure
The NatFibra® fiber of high-aspect-ratio can be distributed over the oil-water area and, together with a continuous three-dimensional network of aqueous phasies, restrict the movement of oil droplets. This structure can be used for decentralized system studies with perfume oil or other oil case components.
In this model, samples that add more than 10% to NatFibra are marked as stable emulsion. The samples did not show the oil water ratio, average process, storage temperature, observation time and evaluation method, and the graphical concentration did not represent the recommended additions to NatFibra® OL oral care.
08 / Scope of application Dental care liquids
For dental care liquids containing particles or droplets
Specific product patterns and permitted raw materials should conform to the oral care regulations and product safety requirements of the target market.
Insoluble powder
For dental care liquids that require control of powder deposition and bottom concentrations.
Decorative particles
Liquid systems that require the maintenance of a spatial distribution and appearance of particles.
Contains fragrance droplets
Water-based dispersion systems for aromatic microdrops or a small amount of oil case.
Low-viscosity liquid systems
Formulation for both particle distribution and dumping, pumping or ejection.
09 / Technical information Parameters and Authentication
Additions and processes are determined according to the target system
The available product information does not give a uniform recommended addition applicable to the entire oral care system. It is proposed to set an addition gradient based on the requirement of a solid content, particle load, droplet ratio, target flow status and stability.
