棕榈仁油 — Frequently Asked Questions

Bio Green Wax Ltd supplies both crude palm kernel oil (CPKO) for buyers with in-house refining capacity, and the more widely used RBD (Refined, Bleached, Deodorised) palm kernel oil — the standard commercial grade for food, cosmetic, and industrial applications. RBD PKO meets international food safety standards with FFA ≤0.1%, moisture ≤0.1%, and a clean, neutral odour. Specify your required grade and application when enquiring — we will confirm the most appropriate specification and documentation package.

Yes. Bio Green Wax Ltd supplies RSPO Segregated (SG) and Mass Balance (MB) certified RBD palm kernel oil, providing full traceability to RSPO-certified sustainable palm kernel processing facilities. RSPO Supply Chain Certificates (SCC) are provided with every certified shipment. ISCC certified grades (ISCC EU and ISCC Plus) are also available for biofuel, biobased materials, and sustainability-reporting applications. EUDR-compliant supply with full plantation-level traceability is available for EU market imports — contact us for the complete compliance documentation package.

RBD palm kernel oil has a melting point of approximately 25–30°C — solid at temperate room temperature but liquid above 30°C — and an iodine value of 14–21 g I₂/100g (AOCS Cd 1-25), reflecting its very high saturated fatty acid content. These properties give PKO its distinctive behaviour as a solid fat at ambient temperature that melts sharply and cleanly — a key functional requirement in confectionery coatings, CBS production, and soap applications. Batch-specific values are confirmed in the CoA.

Yes. RBD palm kernel oil is one of the two primary feedstocks for soap noodle production (alongside palm oil/stearin), contributing lauric acid's exceptional lather, cleansing performance, and hardness to finished soap bars. For oleochemical manufacturers, PKO is split via hydrolysis to produce lauric acid, capric acid, caprylic acid, and glycerine — the building blocks of surfactants, personal care ingredients, and pharmaceutical excipients.

Bio Green Wax Ltd can supply soap-grade and oleochemical-grade PKO with appropriate quality and certification documentation. Contact us to discuss your specific technical requirements.

Palm kernel oil pricing is market-linked and changes daily with global commodity market conditions (Malaysian MPOB reference prices, currency rates, and freight costs). Bio Green Wax Ltd offers competitive pricing with volume discounts for regular procurement. Contact our trading team at sales@biogreenwax.com for current FOB Malaysia/Indonesia or CIF-to-your-destination pricing based on your volume, grade, and delivery schedule. Forward pricing contracts are also available for volume buyers requiring price certainty.

Yes. RBD palm kernel oil and its fractions are the primary raw material for CBS (Cocoa Butter Substitute) and confectionery coating fat production. The high lauric acid content delivers the sharp melting curve — melting near body temperature — that is critical for good mouthfeel and snap in compound chocolate and confectionery coatings. Bio Green Wax Ltd also supplies processed PKO fractions — palm kernel olein and palm kernel stearin — optimised for specific CBS melting point requirements. Contact our sales team with your CBS application specification.

Yes. RBD palm kernel oil and palm kernel olein are key ingredients in non-dairy creamer formulations, filled milk products, and ice cream coating fats. The high lauric acid content provides the solubility and rapid crystallisation behaviour needed for creamer whitening effect and smooth mouthfeel. Bio Green Wax Ltd supplies food-grade PKO with full HACCP, Halal, and RSPO documentation supporting these specialised food applications. Contact us with your creamer or specialty fat application requirements.

Our RBD palm kernel oil meets standard MPOB/PORAM quality specifications: FFA content ≤0.1% (as lauric acid), moisture and volatile matter ≤0.1%, and impurities ≤0.1%. These parameters ensure product quality and stability for food manufacturing and oleochemical applications. Batch-specific values are confirmed in the Certificate of Analysis provided with every shipment — a critical document for your HACCP records and incoming goods quality control.

Yes. Halal certification from internationally recognised Islamic certification bodies is provided as standard with every palm kernel oil shipment from Bio Green Wax Ltd. This certification is required by food manufacturers, soap producers, and cosmetics companies supplying to Muslim consumer markets in the Middle East, Southeast Asia, Africa, and globally. Kosher certification can be arranged on request. Contact us when placing your enquiry to confirm the specific Halal certification body required for your destination market.

Bio Green Wax Ltd supplies palm kernel oil in four formats depending on your volume and infrastructure: ISO tanks (20,000–25,000 litres, most economical for large volumes); food-grade flexitanks (16,000–24,000 litres); 1,000-litre food-grade IBCs; and 200-litre drums. PKO is liquid above approximately 30°C — buyers receiving in solid form should have heating capability at the discharge point. Confirm your receiving infrastructure (heated storage, pump systems) when placing your order so we can advise on the most appropriate supply format.

Lead times from Malaysian or Indonesian origins to European ports are typically 4–6 weeks for CIF deliveries. For Asian buyers within the region, 2–3 weeks. Lead times include production, quality testing, documentation preparation, and ocean transit time. Bio Green Wax Ltd confirms specific lead times at order placement based on vessel schedules and stock availability. Contact us at +44 20 7101 3847 for a current shipment schedule estimate for your destination port.

Yes. Bio Green Wax Ltd supplies the full range of palm kernel fractions: RBD PKO (whole), palm kernel olein (liquid fraction), and palm kernel stearin (solid fraction). Fractionation separates PKO into components with distinct melting points and fatty acid profiles — allowing buyers to precisely match the fat specification for their confectionery, specialty fat, or oleochemical application. All fractions are available with RSPO certification and full food safety documentation. Contact us for the full product specification range.

Bio Green Wax Ltd prepares a comprehensive documentation package for every PKO shipment: Certificate of Analysis; Certificate of Origin; Halal Certificate; Phytosanitary Certificate (where required by destination); Bill of Lading; Packing List; RSPO or ISCC Supply Chain Certificate (for certified supply); and EUDR due diligence statement (for EU imports). For India imports, FSSAI-compatible documentation is prepared. Documents are prepared in accordance with destination country import requirements and provided promptly to support customs clearance.

Yes. Food-grade RBD palm kernel oil from Bio Green Wax Ltd is tested for aflatoxins (B1, B2, G1, G2) in accordance with EU maximum residue level (MRL) regulations and UK FSA requirements. Heavy metals testing (lead, arsenic, cadmium, mercury) is performed for EU and UK food market supply. Test reports from accredited third-party laboratories (ISO 17025 certified) are provided with each food-grade shipment to support your food safety management system and retail customer technical audits.

Yes. ISCC certified palm kernel oil — under ISCC EU (for RED II biofuel compliance) and ISCC Plus (for biobased materials and circular economy supply chains) — is available from Bio Green Wax Ltd. GHG (greenhouse gas) savings calculations meeting RED II Article 31 requirements are provided for biofuel feedstock supply. ISCC Plus documentation supports biobased product claims under EN 16785 and corporate carbon accounting frameworks. Contact us to specify your required ISCC scheme and we will confirm availability and certification documentation.

RBD palm kernel oil has a saponification value of approximately 243–255 mg KOH/g — among the highest of all commercially significant vegetable oils. This high saponification value means PKO reacts with sodium hydroxide very efficiently during soap manufacturing, producing high TFM (Total Fatty Matter) soap with less alkali waste. For soap noodle producers, this translates to a higher-quality soap base with better lather, harder bar, and more efficient production yields compared to palm oil-only formulations.

Yes. Our RBD palm kernel oil is supplied to AOCS (American Oil Chemists' Society) standard quality specifications and can be tested against specific BS EN standards upon request. CoA parameters including FFA, moisture, iodine value, saponification value, peroxide value, and colour are verified against internationally recognised quality benchmarks before each shipment. Copies of AOCS test methods used are available to support your quality system documentation.

RBD palm kernel oil has a shelf life of 24 months from production date in sealed containers stored correctly. Recommended storage: maintain above 30°C in heated tanks or heated storage areas for liquid handling; or store as solid (below melting point) in sealed containers at ambient temperature (15–35°C) away from direct sunlight, moisture, and contamination. The oil's stability at solid-state storage is good — Bio Green Wax Ltd confirms production dates on all documentation and CoAs, supporting your FIFO stock management.
