Technical & Formulation Considerations
| Consideration | Development implication |
|---|---|
| Vehicle selection | Oil-in-water emulsions, aqueous or hydroalcoholic gels, and selected glycol-containing systems are credible starting points. Confirm solubility and recrystallization behavior in the complete formulation. |
| Stability | EGCG can be sensitive to oxygen, strong light, heat and higher-pH aqueous conditions. Establish potency and appearance stability at the finished product’s actual pH and processing conditions. |
| Ingredient compatibility | Screen the complete preservative, antioxidant, chelator, emulsifier and solvent system. Conventional antioxidants should not be assumed to provide protection in every vehicle. |
| Packaging | Evaluate light-restrictive packaging and repeated-use exposure during finished-product stability testing. |
| Finished-product validation | The bulk ingredient’s 24-month shelf life does not establish shelf life in creams, gels or serums. Formulation-specific stability, tolerance and efficacy testing is required. |
Applications
| Application | Commercial development focus |
|---|---|
| Leave-on creams and lotions | Oil-in-water facial and targeted skin-care emulsions |
| Topical gels | Aqueous or hydroalcoholic leave-on systems after compatibility and stability confirmation |
| Serum-type products | Light-protected formulations with validated solubility and potency retention |
| Appearance-care formulations | Products for oily or blemish-prone skin, supported by finished-product tolerance and claim-substantiation testing |
