01 · THE CUSTOMER PROBLEM
Personal-care formulators need robust protection in complex rinse-off and leave-on systems while responding to cleaner-label and sustainability demands.
Low-MW chitosan provides a bio-based antimicrobial hurdle and potential preservative-enhancement route within a formulation-specific system.
Chitosan as a bio-based antimicrobial hurdle and preservative-enhancement platform for rinse-off and leave-on formulations.
02 · RECOMMENDED STARTING POINT
Start with the material designed for the decision.
Its cationic activity and film-forming behavior can support broader preservation systems while contributing a natural, vegan and biodegradable ingredient story.
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.
Preservative enhancement
Preservative enhancement can be developed by matching the chitosan specification, dose and application-ready format to the finished personal-care preservation system.
Microbial-control support
Microbial-control support can be developed by matching the chitosan specification, dose and application-ready format to the finished personal-care preservation system.
Cleaner-label positioning
Cleaner-label positioning can be developed by matching the chitosan specification, dose and application-ready format to the finished personal-care preservation 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.
Finished-form challenge testing
pH and surfactant compatibility
Package, sensory and skin or eye-area safety
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 personal-care preservation grade with a finished-form challenge-test plan.
Start the Sample Brief06 · WHY CHITOSAN
A complementary antimicrobial hurdle
Cationic chitosan can interact with negatively charged microbial surfaces under suitable formulation conditions, while films and coatings retain function where risk is concentrated.
There is no universal concentration. Grade and dose are screened against pH, interacting ingredients, process conditions and the target performance profile.
Target organisms, pH, dose, sensory impact, package and shelf life are validated through finished-form challenge testing.
