Bulk Caffeic Acid Supplier (CAS 331-39-5) – ≥98% HPLC, EU Supply
Caffeic acid NST-10-5 is a light-brown powder supplied for cosmetic and personal-care formulation development. Its most practical uses are in leave-on emulsions, gels and encapsulated delivery systems where limited aqueous solubility, inherent color and oxidation sensitivity can be managed.
Who This Product Is For
| Customer type | Relevant use |
|---|---|
| Cosmetic and personal-care manufacturers | Development of antioxidant-positioned creams, emulsions, gels, films and masks |
| Skin-care and scalp-care formulators | Evaluation in leave-on or encapsulated delivery systems |
| Contract manufacturers and formulation laboratories | Prototype development, compatibility screening and finished-product stability testing |
| Cosmetic ingredient distributors | Supply to professional formulation and manufacturing customers |

Technical & Formulation Considerations
| Solubility | Limited water solubility makes simple clear aqueous products comparatively challenging. Emulsions, validated cosolvent systems or encapsulated formats are more practical starting points. |
|---|---|
| Oxidation and light | Aqueous oxidation and photodegradation should be assessed in the intended formulation and package. Assay retention and color stability require finished-product testing. |
| pH | Increasing ionisation may improve apparent solubility but can also accelerate oxidation. Select pH by evaluating solubility, chemical stability and color together. |
| Processing | Heating may aid dissolution but should not be treated as evidence of process stability. Validate the actual addition point, exposure time and manufacturing conditions. |
| Appearance | The raw material is light brown, making white or colorless formulations more demanding. Monitor precipitation and color drift throughout stability studies. |
| Compatibility | Test directly with the selected emulsifiers, polymers, preservatives, pigments, fragrances and metal-containing ingredients. |
Applications
| Application | Commercial formulation context |
|---|---|
| Leave-on creams and O/W emulsions | Suitable for development where dispersed or encapsulated caffeic acid and some inherent color are acceptable. |
| Hydroalcoholic or polymeric gels | Relevant where a validated solvent system provides uniform incorporation and suitable release. |
| Dry films and masks | Potential format for localized skin delivery without relying on a clear water-only system. |
| Encapsulated skin or scalp products | Vesicles or microparticles may support stability and targeted deposition, subject to delivery-system validation. |
| Lipid-containing cosmetic formulations | May be evaluated as a formula antioxidant, with performance confirmed in the complete finished product. |
Quality & Documentation
The supplier quality specification defines identity by TLC and NMR, assay by HPLC, residue on ignition, loss on drying and limits for heavy metals, lead, arsenic, mercury and cadmium.
Finished-product manufacturers should establish compatibility, physical state, assay retention, color stability and packaging suitability in the intended formulation and process.
