Olive leaf extract

1. Product Overview

Hersoncare’s Olive Leaf Extract is a high-potency botanical ingredient derived from the leaves of Olea Europaea L. (common olive tree), renowned globally for its rich content of oleuropein – the key bioactive compound responsible for its exceptional antioxidant, antibacterial, and anti-inflammatory properties. As a leading supplier of Plant Extracts and Natural Antioxidants, we adhere to strict sourcing and extraction standards to ensure our extract retains maximum efficacy, making it a trusted choice for nutraceutical, pharmaceutical, and cosmetic manufacturers worldwide.

Unlike generic olive leaf extracts, our product is standardized to contain 10%–70% oleuropein (assayed via HPLC) and is complemented by other beneficial compounds such as hydroxytyrosol, flavonoids, and vitamin E. These ingredients work synergistically to support immune function, cardiovascular health, and skin vitality – aligning with the growing global demand for clean, plant-based solutions. Our extract is 100% natural, non-GMO, and free from artificial additives, making it compatible with premium formulations (e.g., paired with our Vitamins and Minerals for enhanced nutrient blends).

Widely recognized for its versatility, Hersoncare’s Olive Leaf Extract is used to enhance product value across industries: from immune-boosting supplements to anti-aging skincare and functional beverages. With a focus on sustainability, we source olive leaves from certified groves to minimize environmental impact, reflecting our commitment to responsible ingredient production.

3. Product Features & Competitive Advantages

• High Oleuropein Potency & Purity: Our extract is standardized to 10%–70% oleuropein (HPLC-tested), with batch-to-batch consistency – a critical factor for manufacturers requiring reliable efficacy. Unlike low-grade extracts (often ≤5% oleuropein), our product delivers measurable health benefits without diluting formulations.
• Multi-Benefit Bioactive Profile: Beyond oleuropein, our extract retains natural hydroxytyrosol and flavonoids – compounds that enhance antioxidant activity by 30% compared to single-ingredient alternatives. This synergy makes it ideal for multi-functional products (e.g., immune + skin health supplements).
• Broad Formulation Versatility: Excellent solubility in water and organic solvents allows integration into capsules, tablets, serums, lotions, and beverages. It pairs seamlessly with our Cosmetic Raw Materials (e.g., Sodium Hyaluronate for anti-aging creams) and Freeze Dried Fruit Powder (for functional smoothies), expanding your product range.
• Rigorous Quality Control: Every batch undergoes 4-stage testing:
  1. Raw material inspection (pesticide residue, heavy metals);
  2. In-process extraction monitoring (to preserve oleuropein);
  3. Final potency testing (HPLC for oleuropein);
  4. Microbial and safety screening (compliant with EU/US standards).
• Sustainable Sourcing: We source olive leaves from Mediterranean groves certified by the Global Organic Textile Standard (GOTS), reducing environmental impact. Our extraction process uses 50% less water than traditional methods, aligning with eco-conscious manufacturing trends.
• Global Compliance: Meets EU Regulation (EC) No. 1924/2006 (food supplements), US FDA GRAS standards, and Kosher certification – eliminating market access barriers for international clients.

4. Step-by-Step Usage Guidelines (Formulation)

Follow these steps to integrate Hersoncare’s Olive Leaf Extract into your products, ensuring optimal stability, efficacy, and user safety:

1. Pre-Formulation Compatibility Test
   • Test a 5g sample in your base (water, glycerin, or powder blend) at 25–30℃. For liquid bases: stir for 2–3 minutes until fully dissolved (no clumps).
   • For oil-based formulations (e.g., facial oils), mix with a small amount of ethanol (5% of total volume) first to improve solubility, then add to the oil base.
2. Dosage Calculation (By Industry)
   • Nutraceuticals: Add 2%–5% extract (e.g., 200mg–500mg per capsule) to deliver 20mg–350mg oleuropein per serving (compliant with EU/US daily intake guidelines).
   • Cosmetics: Use 0.5%–2% in serums/creams (e.g., 5g–20g per 1kg formulation) to leverage antioxidant and anti-inflammatory benefits without altering texture.
   • Functional Beverages: Add 0.1%–0.3% extract (e.g., 1g–3g per 1L drink) – mix with warm water (40–50℃) first, then blend into the beverage base to avoid sediment.
3. Powder Blending (Supplements/Functional Foods)
   • Mix the extract with other powdered ingredients (e.g., Vitamins and Minerals like Vitamin C, or Freeze Dried Fruit Powder) in a low-speed blender (500–800 RPM) for 5–8 minutes to ensure uniform distribution.
   • Avoid blending with high-fat ingredients (e.g., cocoa butter) without a dispersant (e.g., maltodextrin) – this prevents clumping and ensures consistent dosing.
4. Stability Testing
   • Store the finished product at 25℃ (60% relative humidity) for 3 months. Retest oleuropein content via HPLC – a loss of ≤5% indicates stable formulation.
   • For liquid products: Add 0.1% natural preservative (e.g., sodium benzoate) to prevent microbial growth (our extract is compatible with all food-grade preservatives).
5. Packaging & Storage
   • Package finished products in opaque, airtight containers (e.g., amber glass bottles for cosmetics, foil-lined pouches for powders) to protect against light and oxygen (which degrade oleuropein).
   • Label products with "Store in a cool, dry place" – this extends shelf-life and maintains efficacy.
