01 · THE CUSTOMER PROBLEM
Cosmetic brands need broader microbial protection and cleaner labels without compromising stability, sensory performance or challenge-test results.
Low-MW chitosan can be screened as an antimicrobial hurdle or preservative enhancer within a formulation-specific protection system.
A bio-based antimicrobial and formulation tool that can support a broader preservation system.
02 · RECOMMENDED STARTING POINT
Start with the material designed for the decision.
Selected chitosan grades can be evaluated as a hurdle or preservative enhancer, potentially reducing reliance on selected synthetic preservatives after challenge testing.
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.
Preservation-system support
Preservation-system support can be developed by matching the chitosan specification, dose and application-ready format to the finished natural preservation support system.
Antimicrobial surface activity
Antimicrobial surface activity can be developed by matching the chitosan specification, dose and application-ready format to the finished natural preservation support system.
Clean-label positioning
Clean-label positioning can be developed by matching the chitosan specification, dose and application-ready format to the finished natural preservation 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.
Challenge-test performance
Target-organism spectrum and dose
Formula stability, sensory and package compatibility
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 BioFoundry low-MW preservative-support grade with a challenge-test plan.
Start the Sample Brief06 · WHY CHITOSAN
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.
