Surge product with bio-cellulose suspension stabilizer
NatFibra® SP / SP Plus
For shampoo, bathing and granular cleaning systems
The source of fermentation, NatFibra® fiber, is interwoven after the aqueous case, forming a continuous three-dimensional network that provides structural support for beads, sand particles, dusting activity and other insoluble dispersions.

01Material structure
NatFibra® Fiber Structure
High-aspect-ratio fibers form a continuous network
The cellulose is made of glucose monomer connections via β-1,4 glycosidic bond. NatFibra® SP uses NatFibra® fiber in diameter of approximately 20-40 nm, longer than micrometres.
The higher spect rateo and surface area connect fibres in liquids, forming an insoluble α-Link three-dimensional network.
α-Link 3D microfibrilProvide structural support for dispersing phases during static
The glucose chain is organized in stages into a nanofibrils and a microfibrils structure.High-aspect-ratio fibre interwoven into a continuous network
Fermentation, purification and product formation
Bio-cellulose from sugar fermentation
bio-cellulose has been purified and integrated into the product, and is fed in accordance with the dispersion of the system and the need for suspension.
02Suspended Authentication
Nironball suspended test
Yield stress indicates structural strength at rest
The test uses the nylon beads with a density of 1.13 g/ml and a diameter of 3.175 mm. The nylon beads sink rapidly in base shampoo; after joining NatFibra® SP, they remain scattered in the same system.

Network structures are not the same as simply increasing overall viscosity. Formulation needs to be developed simultaneously to look at yield conditions, oscillation fluids, viscosity, particle specifications and high temperature storage.

Dynamic Combination
Foaming, rinsing, wet-combing and dry-combing stages
Lower combing means lower combing resistance. Combination is determined by a combination of surfactants, anion polymers, silicon oils and other adjustments.
01Foam and bleaching phase
In the foam phase, 5% of Benchmark A samples were combed with less than 5% NatFibra® SP; during the bleaching phase, no significant differences were observed between the samples.
02Wetting phase
The rate of change in combustration is as follows: basic formulation - 63.72 per cent, Benchmark A - 62.35 per cent, NatFibra® SP - 56.64 per cent and U20-69.93 per cent.
03Dry-up phase
The rate of change in condensing is as follows: basic-formulation-62.20 per cent, Benchmark A-61.68 per cent, NatFibra® SP-65.35 per cent, U20-58.58 per cent.
05Baptization application validation

The particle size is a key variable for suspended stability. Small, medium and fine grains of sand can be tested for storage at the corresponding high temperature; large particles are not passed under current conditions of formulation and need to be re-validated after adjusting the amount of suspended stabilizers, structure or particle specifications.
