01 · THE CUSTOMER PROBLEM
Formulators need to tune viscosity, pickup and after-feel while maintaining emulsion stability and reducing reliance on persistent rheology modifiers.
In compatible systems, specification-controlled chitosan can influence droplet, particle and polymer interactions to create differentiated texture.
A specification-driven biopolymer for rheology, interfacial behavior and sensorial development.
02 · RECOMMENDED STARTING POINT
Start with the material designed for the decision.
In compatible systems, chitosan can interact with droplets, particles and other polymers to help formulators tune body, pickup and after-feel.
Without the shell
Controlled fungal sourcing supports a traceable, non-animal supply strategy.
Specification engineered
MW, DDA, purity, charge density and format are selected around the target result.
Application ready
Powder is only the starting point; Mykito also develops films, fibers, gels, coatings and formulations.
One technical partner
Material selection, formulation support and the validation plan are connected from the first sample.
03 · PERFORMANCE TARGETS
Build toward outcomes a buyer can measure.
Rheology tuning
Rheology tuning can be developed by matching the chitosan specification, dose and application-ready format to the finished texture + emulsion support system.
Particle interaction
Particle interaction can be developed by matching the chitosan specification, dose and application-ready format to the finished texture + emulsion support system.
Sensorial differentiation
Sensorial differentiation can be developed by matching the chitosan specification, dose and application-ready format to the finished texture + emulsion support system.
04 · GO / NO-GO CRITERIA
Define the evidence before testing begins.
The first program is designed around three decision-making outputs—not an open-ended material trial.
Viscosity curve and process order
Emulsion stability
Sensory panel and ingredient-reduction potential
05 · FROM SAMPLE TO DECISION
A practical application program,
not a bag of powder.
Define
Agree on the function, baseline, constraints and measurable success criteria.
Screen
Select the MW, DDA, purity, dose and physical format that fit the application.
Validate
Test the winning system in the finished formulation, device, process or use environment.
Recommended first request: A three-level BioFoundry viscosity and compatibility screening set.

Deposition + hydrated film formation
Cationic charge and interfacial adhesion can increase surface residence, while continuous polymer films support moisture management and active carrying.
There is no universal concentration. Grade and dose are screened against pH, interacting ingredients, process conditions and the target performance profile.
Appearance, sensory, stability, preservation and performance are validated in the finished cosmetic formula.
