Rosmarinic Acid Powder Extrac: Water-Soluble Antioxidant- AIHerba

Bulk Rosmarinic Acid Powder (5% – 98% HPLC) | GMP Factory Direct Supply

AIHerba is a globally recognized GMP-certified manufacturer and wholesale supplier of premium Rosmarinic Acid Powder. Sustainably extracted from the leaves of Rosmarinus officinalis, our Rosmarinic Acid serves as an elite, water-soluble natural antioxidant and clean-label preservative for the food, beverage, dietary supplement, and cosmetic industries.

Unlike generic trading companies, we control the entire supply chain. Using a strict hexane-free water and food-grade ethanol extraction process, we produce highly purified (up to 98%) extracts that perfectly replace synthetic antioxidants like BHT, BHA, and EDTA without altering the color or flavor profile of your finished products.

1. Product Identity & Clean Extraction Integrity

The efficacy of a botanical antioxidant relies entirely on its extraction purity. At AIHerba’s Advanced Extraction Facility, we do not use toxic solvents like Methanol, Ethyl Acetate, or Hexane.

• Botanical Source: Rosmarinus officinalis L. (Rosemary leaves from high-altitude, unpolluted cultivation bases).

• Solvent System: Purified Water & Food-Grade Ethanol only.

• Deodorization: Our 98% high-purity grade undergoes a specialized solvent-recovery and deodorization process, completely removing the strong “herbaceous odor” typical of lower-grade extracts.

2. Physicochemical Properties for Formulators

To ensure seamless integration and stability in your aqueous formulas, please review our typical batch parameters. (For full QA protocols, visit ourGMP Herbal Extract Quality Consistency page).

• pH Stability: Highly stable in mildly acidic to neutral environments (pH 3.0 – 6.5).

• Thermal Stability: Withstands standard pasteurization and UHT processing (up to 120°C for short durations) without antioxidant degradation.

3. Mechanism of Action: The Clean-Label Preservative

Rosmarinic Acid is a potent caffeic acid ester. Rather than making medical claims, we focus on its industrial and biochemical utility:

1. Free Radical Scavenging: Its multiple phenolic hydroxyl groups act as hydrogen donors, rapidly neutralizing reactive oxygen species (ROS) and halting oxidative chain reactions.

2. Metal Chelating: It acts as a natural chelator, binding to transition metal ions to prevent them from catalyzing lipid peroxidation—functioning as a natural alternative to EDTA.

4. B2B Industrial Applications

Because Rosmarinic Acid is hydrophilic (water-soluble), it is the exact opposite of Carnosic Acid (which is lipid-soluble). This makes it ideal for:

• Clear Functional Beverages & RTD Teas: Dissolves completely without causing turbidity or sedimentation. It protects natural pigments (like anthocyanins) and delicate flavor compounds from UV and oxygen degradation.

• Cosmetics & Personal Care (INCI: Rosmarinic Acid): Incorporated into water-based anti-aging serums, toners, and soothing lotions to protect the skin matrix from environmental oxidative stress.

• Dietary Supplements: Used in nootropic and immune-support hard shell capsules, often synergistically combined with Vitamin C.

• Meat & Seafood Processing: Prevents lipid peroxidation in aqueous marinades, retaining fresh color and extending shelf life.

5. Global Logistics, Packaging & HS Code

We understand that accurate logistics data is critical for accurate landed-cost calculations.

• HS Code (Customs):

  • 2918.99.0090 (For high-purity 98% single compound)

  • 1302.19.9099 (For standard extracts 5%-30%)

• Standard Packaging: 25kg / Export-Grade Fiber Drum.

• Dimensions & Weight: 38cm (Diameter) x 50cm (Height) | Gross Weight: 27.5kg.

• Inner Packaging: Double-layer pharmaceutical-grade LDPE bags, vacuum-sealed with heavy-duty desiccants.

• Minimum Order Quantity (MOQ): 25kg (Commercial); 1kg-5kg (R&D Pilot Runs).

• Shelf Life: 24 Months when stored in a cool, dry place (<25°C) away from direct sunlight.

  

6. Frequently Asked Questions (Formulator & Procurement FAQ)

Q1: What is the exact difference between Rosmarinic Acid and Carnosic Acid?
A: The fundamental difference is polarity. Rosmarinic Acid is water-soluble, making it the correct choice for beverages, aqueous cosmetics, and meat products. Carnosic Acid is fat/oil-soluble, making it ideal for protecting edible frying oils, softgels, and Omega-3 fish oil from rancidity.

Q2: Will the 5% or 10% Rosmarinic Acid alter the color of my transparent beverage?
A: Lower purity extracts (5%-20%) naturally have a yellowish-brown tint and a slight herbal odor, which may affect highly transparent liquids. For clear, flavor-sensitive formulations, we strictly recommend our 98% deodorized Rosmarinic Acid, which dissolves virtually colorless and odorless.

Q3: Are AIHerba’s Rosemary Extracts tested for pesticide residues and heavy metals?
A: Yes. Every batch is rigorously screened for over 500 pesticide items conforming to USP <561> and EC 396/2005 standards. Heavy metals are tested via ICP-MS to ensure strict compliance with California Prop 65 and EU regulations.

Q4: Is your material ETO-free and non-irradiated?
A: Absolutely. We utilize high-temperature short-time (HTST) steam sterilization to control microbial limits, guaranteeing the product is 100% free from Ethylene Oxide (ETO) and irradiation.
