Our rosemary extract is manufactured by ethanol‑water dual‑phase extraction, purification and spray‑drying. Multiple separation steps remove leaf debris, coarse fibre and other irrelevant impurities to preserve stable levels of carnosic acid and rosmarinic acid. Many bulk rosemary extracts on the market show fluctuating active values due to inconsistent raw‑leaf quality and simplified processing, which brings risks for finished‑product stability. Our rosemary extract powder delivers even colour, fine particle size and good flowability, keeping consistent performance batch‑to‑batch for large‑scale formulation. No artificial colours, synthetic preservatives or redundant fillers are added throughout production.

Core Functions & Benefits
Rosemary extract contains natural carnosic acid, rosmarinic acid and other phenolic compounds to provide gentle plant‑derived antioxidant support.
Effective antioxidant support: Helps neutralize excess free radicals and ease oxidative stress caused by metabolism and external factors.
Food‑grade antioxidant performance: Helps slow down lipid oxidation, widely adopted as natural antioxidant for oil‑containing products.
Skin‑care supportive properties: Added into topical cosmetic formulas to reduce oxidative damage to skin tissue.
Daily nutritional support: Used in compound supplement blends for overall body wellness maintenance.
Note: Most supporting data comes from laboratory and pre‑clinical studies; human clinical research is still ongoing.
Application Fields
Thanks to stable active composition and good formula compatibility, rosemary extract is widely applied across multiple global industries:
Food Industry: Natural food antioxidant for edible oils, meat products, baked goods and fat‑containing food items
Dietary Supplements: Antioxidant capsules, compound herbal nutritional blends, daily wellness tablets
Cosmetic & Personal‑Care Raw Materials: Antioxidant additives for creams, lotions, serums and toners
Research & Development Raw Materials: Standard botanical reference material for lab testing and new‑formula development
Our Supplier Advantages

Rigorous raw‑material screening: Qualified rosemary leaves are selected; regular testing covers heavy metals, pesticide residues and microbial limits.
Optimized purification process: Effectively removes plant debris and miscellaneous impurities to secure stable carnosic acid and rosmarinic acid content.
Batch‑by‑batch full inspection: Each shipment completes HPLC test for active ingredients, moisture, heavy‑metal and microbial detection before release.
Custom service available: Support active ingredient adjustment, particle‑size modification and private‑label packaging solutions.
Flexible ordering: 1 kg sample orders are acceptable. Complete export documents including COA, MSDS and test reports can be provided for customs clearance.
Packaging & Storage Guidelines
Standard Export Packaging: 1 kg aluminum foil bag; 25 kg food‑grade fiber drum with inner plastic lining bag
Storage Conditions: Store in cool, dry, dark and ventilated warehouse. Keep away from high temperature, moisture and direct sunlight.
Important Reminder: Keep tightly sealed after opening. Phenolic substances in rosemary extract are sensitive to heat, light and oxidation; improper storage will trigger colour darkening and activity loss.
FAQ
Q1: What are the key testing components for rosemary extract?
A1: Carnosic acid and rosmarinic acid are the core active markers for commercial rosemary extract, widely recognised by global manufacturers. We can supply goods matching your target specification.
Q2: What is the difference between raw rosemary leaf powder and concentrated rosemary extract?
A2: Plain leaf powder contains large amounts of fibre with low levels of carnosic acid and rosmarinic acid. Concentrated extract enriches phenolic active substances with stable test values and works better for standardized finished‑product manufacturing.
Q3: What about MOQ and lead‑time?
A3: MOQ starts at 1 kg for sample evaluation. Bulk goods are normally in stock. Custom‑spec orders need separate lead‑time confirmation.
