Bulk Fisetin Supplier (CAS 528-48-3) – ≥98% HPLC, EU Supply
NST Chemicals Fisetin NST-10-62 is a high-purity, light-yellow fine powder sourced from the bark and stem of Cotinus coggygria Scop. It is supplied for cosmetic and personal-care formulation development, particularly where a validated concentrate, dispersion or encapsulated delivery system will be used.
Who This Product Is For
| Customer type | Typical requirement |
|---|---|
| Cosmetic and personal-care manufacturers | Fisetin for leave-on body-care and facial-care development |
| Contract manufacturers | High-purity powder for customer-specific prototypes and finished-product validation |
| R&D and formulation teams | Vehicle screening, compatibility studies and delivery-system development |
| Cosmetic ingredient distributors | Documented fisetin powder for professional manufacturing customers |

Technical & Formulation Considerations
| Solubility | Fisetin has very low water solubility and limited solubility in conventional oil phases. Direct addition to aqueous or oil-based products should not be assumed to produce a clear, stable solution. |
|---|---|
| Development approach | Hydroglycolic or hydroalcoholic concentrates, validated dispersions and encapsulated systems are more realistic starting points than direct powder addition. |
| Process conditions | Published studies indicate that aqueous degradation can increase with higher pH and temperature. Assay retention must be validated in the intended formula and manufacturing process. |
| Appearance impact | The powder’s light-yellow color may be visible in white emulsions or transparent products. Finished-product color and staining should be evaluated. |
| Grade boundaries | This product is a high-purity fisetin powder, not a ready-made hydroglycolic concentrate, botanical extract or encapsulated delivery system. |
Applications
| Application area | Development context |
|---|---|
| Leave-on body gels and serums | Use with a validated concentrate or delivery system, followed by compatibility and stability testing. |
| Body-care emulsions | Suitable for skin-conditioning and antioxidant-oriented formulation concepts when finished-product performance is substantiated. |
| Encapsulated facial-care formulations | A development option where improved dispersion and controlled skin delivery are formulation objectives. |
