Import Beta Carotene 30% Os — Buy in Bulk from Supplier in China

Beta Carotene 30% OS is an oil-soluble suspension concentrate manufactured by Dongying Haifu Food Technology Co., Ltd. in Shandong Province, China. The 30% designation indicates a substantially higher active loading than standard 1% or 10% preparations, achieved through dispersion of crystalline beta carotene in edible vegetable oil with emulsifier stabilisation. The OS (oil soluble) format targets fat-based food systems, soft gelatin capsule manufacturing, and oil-based cosmetic formulations where direct aqueous dispersion is unnecessary. The CAS number 7235-40-7 and EINECS 230-636-6 confirm the identity of the active chromophore.

The oil carrier typically comprises medium-chain triglycerides, sunflower oil, or palm olein, with polyglycerol esters of fatty acids or lecithin as emulsifiers to prevent crystal settling and agglomeration. The bright orange colour arises from the conjugated polyene chain of beta carotene with eleven double bonds, absorbing strongly at 450-460 nm in hexane. Standard specifications for 30% OS suspensions include viscosity below 5000 mPa.s at 25°C, particle size below 5 micrometres for injection moulding or capsule filling uniformity, and acid value below 2.0 mg KOH/g for oxidative stability. The higher concentration reduces transportation and storage costs per unit active but requires more sophisticated dispersion equipment in downstream processing.

Primary buyers include softgel contract manufacturers, margarine and shortening producers, and oil-based nutraceutical formulators. The 30% strength suits high-throughput operations where dilution to final use concentration occurs in-line. Cosmetics applications encompass tanning products and anti-ageing oil serums where lipophilic delivery enhances skin penetration. Pharmaceutical buyers use it for vitamin A premixes where provitamin A activity requires precise IU calculation based on all-trans content. Prospective purchasers should confirm the specific oil carrier to assess compatibility with their formulation matrix and to address allergen or kosher certification requirements.

Dongying Haifu Food Technology Co., Ltd. maintains its registered address at Minghe East Road, Hekou District, Dongying 257200, Shandong Province, China. The company holds imported supplier tier and harbour trust tier classifications. Platform metrics show a 0.00% response rate with no recorded average response hours, suggesting that inquiry management does not occur through the platform's messaging infrastructure. Direct contact via the published physical address or telephone may prove more effective for technical discussions or sample requests.

The supplier lists both 10% CWS and 30% OS beta carotene variants, indicating formulation capability across delivery systems, though whether this reflects in-house manufacturing or toll processing is unstated. No information on establishment year, production scale, R&D staffing, or number of production lines appears in the source data. ISO and SGS certifications are claimed in the source text but lack certificate numbers, scopes, or validity dates for independent verification. No named customers, export destinations, or revenue figures are provided. Buyers should conduct due diligence on manufacturing practice through site audit or third-party inspection given the limited verifiable credentials.
