Ingredient Information for Cosmetic Formulation

Here is the information regarding the two ingredients you inquired about, based on the details from MySkinRecipes:

Pro Polymer (Acrylate Crosspolymer)

• Identity: Pro Polymer is Acrylate Crosspolymer, not Carbopol. It is a different ingredient with distinct properties.
• Properties & Usage: It is known for being easier to use than Carbopol and has high tolerance to electrolytes and acids, making it suitable for formulations like AHA or BHA gels. It functions as a thickener to create gel textures in water-based formulas and creamy textures in water+oil formulas. It can create a high-viscosity gel suitable for suspending beads in scrubs without stickiness. At higher concentrations (>3%), it can create a creamy pudding-like texture.
• INCI Name: ACRYLATES/C10-30 ALKYL ACRYLATE CROSSPOLYMER

Green Tea Extract (Hi-EGCG™)

• Identity: The Green Tea Extract available is Hi-EGCG™ (Green Tea Extract).
• EGCG Concentration: It is standardized to contain a minimum of 2% EGCG (Epigallocatechin gallate).
• Concentration Efficacy: The 2% EGCG concentration is considered high and effective. It is significantly more concentrated (approximately 133 times) than EGCG found in brewed green tea. While other compounds are present, the product is standardized based on the 2% EGCG content.
• Reason for 2%: The concentration is set at 2% because very high concentrations (like 20% mentioned in older products) can lead to EGCG precipitation in certain formulations, reducing its effectiveness as the skin cannot absorb it properly. The 2% concentration offers a balance of efficacy and stability.
• Benefits: EGCG is a powerful antioxidant effective in preventing cell damage, repairing skin damage from UVA/UVB, reducing acne by decreasing oil production and inflammation, and improving skin elasticity.
• Usage Rate: Recommended usage rate is 1-5%.
• Mixing: Mix in the final step below 40°C and at a pH between 4.0-6.5. It is recommended to use ActiveProtec™ OX 1% to help protect against metal ions.
• INCI Name: Camellia Sinensis Leaf Extract

Both ingredients are cosmetic grade.
