01 · THE CUSTOMER PROBLEM
Colour products must balance pigment deposition, adhesion, wear and removability while meeting demand for more biodegradable formulation tools.
Chitosan's positive charge and film formation provide a bio-based lever for pigment interaction and surface adhesion in compatible systems.
A natural film former and particle-interaction tool for selected colour-cosmetic formulations.
02 · RECOMMENDED STARTING POINT
Start with the material designed for the decision.
Positive charge and film formation create formulation levers for pigment deposition, wear, adhesion and active delivery in compatible colour systems.
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.
Pigment deposition
Pigment deposition can be developed by matching the chitosan specification, dose and application-ready format to the finished colour cosmetics system.
Film integrity
Film integrity can be developed by matching the chitosan specification, dose and application-ready format to the finished colour cosmetics system.
Wear and adhesion support
Wear and adhesion support can be developed by matching the chitosan specification, dose and application-ready format to the finished colour cosmetics 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.
Pigment and ionic compatibility
Spreadability, adhesion and wear
Colour stability and removal
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 film-forming cosmetic grade for pigment-compatibility screening.

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.
