Micromul™ EGCG: Properties, Usage, and Expiration
Question
Could you provide detailed information about Micromul™ EGCG (Microemulsion Epigallocatechin Gallate)? Specifically, I would like to understand:
- Its key properties and benefits for skincare, including its mechanism of action.
- Recommended usage instructions, such as dissolution method, heat avoidance, and ideal usage rate (e.g., for anti-aging and antioxidant benefits).
- Its physical appearance.
- Optimal long-term storage conditions.
- What implications the expiration date (e.g., 08/2025) has on its efficacy, stability, and quality after this period?
Answer
Micromul™ EGCG (Microemulsion Epigallocatechin Gallate) is a highly effective ingredient for skincare, delivered in a nano-level microemulsion form with an average particle size of 1.7 nanometers, allowing for excellent absorption into the skin.
This ingredient offers several benefits:
- Moisture Retention: It helps synthesize Natural Moisturizing Factors (NMFs) and enhances the skin's ability to retain moisture by reducing hyaluronic acid degradation.
- Antioxidant Properties: Micromul™ EGCG acts as a potent antioxidant, scavenging free radicals and regulating reactive oxygen species (ROS) to protect the skin from environmental damage.
- Anti-Cell Death: It exhibits properties that help prevent cell death, contributing to overall skin health.
- Skin Brightening: It can help whiten and brighten the skin by significantly reducing melanin secretion and production.
For optimal use, Micromul™ EGCG should be dissolved in water, and heat should be avoided during mixing. The recommended usage rate is 1-5%, with 2-3% being ideal for anti-aging and antioxidant benefits in skincare formulations. It appears as a clear liquid. For long-term storage, keep it at room temperature, away from sunlight, heat, and humidity, and ensure the lid is tightly closed. The product has a shelf life of at least 2 years.
Regarding the expiration date of 08/2025, it indicates the period during which the product is expected to remain stable and effective under proper storage conditions. After this date, while the product may not immediately become harmful, its efficacy, stability, and overall quality (such as color, odor, and texture) cannot be guaranteed. We recommend using the product within its stated shelf life to ensure maximum performance and safety in your formulations.
