01 · THE CUSTOMER PROBLEM
Foundation and mascara need flexible adhesion, wear and water resistance without flaking, smudging or difficult removal.
A properly selected chitosan grade can act as a bio-based film former and deposition aid across complexion and lash prototypes.
Cationic film formation for evaluating coverage, adhesion and water-resistance support in complexion and lash products.
02 · RECOMMENDED STARTING POINT
Start with the material designed for the decision.
A properly selected chitosan grade can be screened as a bio-based film former or deposition aid in foundation and mascara prototypes.
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.
Surface adhesion
Surface adhesion can be developed by matching the chitosan specification, dose and application-ready format to the finished foundation + mascara system.
Flexible film formation
Flexible film formation can be developed by matching the chitosan specification, dose and application-ready format to the finished foundation + mascara system.
Pigment and fiber deposition
Pigment and fiber deposition can be developed by matching the chitosan specification, dose and application-ready format to the finished foundation + mascara 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.
Wear, flaking and smudging
Water resistance and removal
Eye-area or skin 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 film-forming grade for side-by-side foundation or mascara prototyping.
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.
