HA6996 Rosemary Extract Powder

Rosemary Extract Powder Description

Rosemary Extract Powder is a hygroscopic fine powder, exhibiting a colour range from light brown to tan, with a distinctive herbal aroma. The primary bioactive constituents include rosmarinic acid, carnosic acid, flavonoids (apigenin, luteolin), and phenolic diterpenes. Rosmarinic acid demonstrates significant free-radical scavenging capacity by donating hydrogen atoms to neutralise reactive oxygen species (ROS), inhibiting lipid peroxidation with IC50 values lower than synthetic antioxidants such as BHT. Diterpenes modulate inflammatory pathways through suppression of TNF-α, IL-6, and COX-2 enzymes, thus reducing edema and cellular damage. The extract remains thermally stable below 60°C but degrades at higher temperatures, necessitating low-heat processing. It exhibits pH-dependent solubility, dissolving readily in hydroalcoholic solutions while forming colloids in water due to polyphenol aggregation. Analytical profiles confirm interactions between flavonoids and organic acids that enhance bioavailability through potentiation of pharmacokinetics. Heavy metal residues comply with pharmacopeial standards (lead ≤20 ppm), while residual solvents are maintained below 5,000 ppm. Stability requires protection from UV light and moisture to prevent oxidation of phenolic rings, with optimal storage in airtight containers at 15–25°C for a shelf life of 24 months.

Rosemary Extract Powder Applications

• Cosmetics and Personal Care: Incorporated into anti-aging serums, moisturisers, and hair care formulations to provide antioxidant and anti-inflammatory benefits. Rosmarinic acid inhibits elastase and collagenase, reducing wrinkles and improving skin elasticity, while diterpenes promote scalp microcirculation, enhancing hair follicle activity and minimizing alopecia. Formulations at concentrations of 0.2%–5% also address acne through antimicrobial action against Cutibacterium acnes.
• Food and Beverage Industry: Used as a natural preservative in meats, oils, and baked goods to inhibit lipid oxidation. At a concentration of 0.3%, it decreases peroxide values by 17.8% and malondialdehyde formation by 17.2% in processed meats such as bacon, thereby extending shelf life without synthetic additives. It works in conjunction with ascorbic acid in functional beverages for enhanced delivery of antioxidants.
• Pharmaceuticals and Nutraceuticals: Incorporated into capsules and tablets for their anti-inflammatory and neuroprotective effects. Rosmarinic acid crosses the blood-brain barrier to inhibit monoamine oxidase (MAO) and acetylcholinesterase, alleviating anxiety and cognitive decline. Topical gels containing 2% extract can accelerate wound healing by 40% through promotion of angiogenesis and reduction of bacterial load.
• Agriculture and Biopesticides: Utilised as a biopesticide against agricultural pests such as Spodoptera litura larvae. The diterpenes disrupt insect molting and feeding behaviours, offering residue-free crop protection. Additionally, it forms part of active food packaging films that reduce meat oxidation by 34%.
• Biomedical Materials and Research: Embedded in nanohydroxyapatite composites for bone implants to mitigate oxidative stress following surgery. Acts as a drug carrier in osteoplasty materials, with zinc oxide nanoparticles enhancing sustained release and antioxidant efficacy (93.97% activity retention at 54 hours).

Rosemary Extract Powder FAQs

Q1. Will this help my acne-prone skin without causing dryness?

Yes. The rosmarinic acid reduces inflammation and kills acne bacteria, while antioxidants mitigate redness. Utilise serums with concentrations of 2%–3%—they are non-comedogenic and hydrating for sensitive skin.

Q2. Can I add it to cooking oil to prevent rancidity?

Absolutely. Blend 0.5g of powder per litre of oil. It inhibits oxidation three times longer than BHT, preserving freshness without altering flavour. Heat below 60°C to maintain efficacy.

Q3. Is it safe with blood thinners like warfarin?

Avoid the combination. Rosemary may enhance anticoagulant effects. Consult your doctor prior to use if on blood thinners or antiplatelet drugs.

1.       Common Preparation Methods

The production of Rosemary Extract Powder begins with sustainably harvested Rosmarinus officinalis leaves, typically sourced from organic Mediterranean farms. Fresh leaves undergo washing with ozonated water, followed by shade-drying at ≤40°C to preserve thermolabile compounds. Dried leaves are coarsely ground and subjected to ethanol-water extraction (50%–70% ethanol) at 40–60°C for 4–6 hours. The liquid extract is filtered to remove particulates, concentrated via vacuum evaporation at 45°C, and purified through macroporous resin chromatography to isolate rosmarinic acid while removing tannins and chlorophyll. The refined concentrate is standardised to 2%–18% rosmarinic acid and spray-dried with maltodextrin or silica as a carrier, yielding a free-flowing powder. Rigorous quality control employs HPLC to validate active compound profiles, residual solvent analysis (ethanol ≤5,000 ppm), heavy metal screening (Pb ≤20 ppm), and microbial testing to ensure compliance with international standards for cosmetic, food, and pharmaceutical use.
