棕榈硬脂酸 — Frequently Asked Questions

Bio Green Wax supplies palm stearic acid in the following grades: Single-pressed (commercial grade, C16+C18 blend), Double-pressed (higher stearic content, suitable for most soap and industrial applications), and Triple-pressed (95%+ stearic acid, pharmaceutical and premium cosmetic grade). Each grade is available with Halal certification and full CoA documentation.

Triple-pressed grades are ideal for applications requiring high stearic acid purity, such as pharmaceutical excipients, premium soap bars, and high-performance cosmetics. Contact us to discuss your purity requirement and we will recommend the appropriate grade.

Yes. Palm stearic acid is one of the most important raw materials in soap manufacturing, providing hardness, lather density, and bar longevity. Bio Green Wax supplies commercial and triple-pressed palm stearic acid specifically suited for toilet soap bars, laundry bars, and speciality soap formulations.

Our stearic acid is Halal certified, RSPO-traceable, and meets AOCS and EN quality standards required by major soap noodle and direct soap producers. We supply to soap manufacturers in Africa, the Middle East, India, and Southeast Asia with competitive CIF pricing and flexible shipment scheduling.

Our palm stearic acid has a titre (solidification point) of 54–57°C for double-pressed grades and 58–62°C for triple-pressed grades, confirming its predominantly saturated C16/C18 composition. The acid value (AV) is typically 195–210 mg KOH/g, with tighter specifications available for pharmaceutical-grade material. These values are confirmed by accredited laboratory testing on every production batch. Full technical data sheets with titre, AV, iodine value, saponification value, colour, and moisture specifications are available on request from our technical team.

Yes. All palm stearic acid supplied by Bio Green Wax is available with Halal certification from a recognised Islamic certification body. Halal certification is increasingly required by cosmetics, pharmaceutical, and food-adjacent B2B buyers across the Middle East, Southeast Asia, and Muslim-majority markets globally. Kosher certification can also be arranged on request. Halal certificate documentation is provided alongside standard shipping documents. For buyers requiring both Halal and RSPO certification, please indicate this at the time of enquiry.

Palm stearic acid prices fluctuate in line with crude palm oil, palm kernel oil, and oleochemical market conditions. Bio Green Wax offers competitive CIF and FOB pricing for all destination ports. We encourage buyers to contact our sales team directly for a current market price quotation, as we update pricing weekly. Volume commitments, long-term contracts, and regular shipment schedules all attract preferential pricing. Spot and forward contract pricing are both available. Please share your destination port, required grade, and estimated annual volume when requesting a quotation.

Yes. Palm stearic acid is a widely used additive in paraffin wax candle formulations, typically added at 3–10% by weight to increase candle hardness, opacity, and mould release. Bio Green Wax supplies commercial-grade palm stearic acid (double-pressed, C16/C18 blend) that is specifically suited for candle manufacturing. It improves the appearance of pillar candles, reduces surface tackiness, and enhances mould release. Our technical team can advise on optimal addition rates for your wax formulation and application. Contact us for a supply quotation and sample.

Our palm stearic acid has an iodine value (IV) of less than 2.0 g I2/100g for triple-pressed grades and typically 2–5 for double-pressed commercial grades, confirming its highly saturated composition. The saponification value (SV) is 193–210 mg KOH/g depending on grade. Low iodine value is particularly important for soap manufacturers seeking hard, white bars with excellent stability. Full analytical specifications are provided in the Certificate of Analysis for every lot. Contact our technical team for specification sheets.

Yes. Palm stearic acid is an essential processing aid and activator in rubber vulcanisation, where it functions alongside zinc oxide to activate the sulphur vulcanisation system. Bio Green Wax supplies commercial-grade (double-pressed) palm stearic acid meeting the requirements of major tyre and rubber goods manufacturers. Our stearic acid is tested for titre, acid value, iodine value, and colour, and is supplied in 25 kg bags or bulk for ease of handling in rubber compound mixing lines. Contact us for a dedicated industrial rubber-grade quotation.

Palm stearic acid from Bio Green Wax is available in the following packaging formats: 25 kg kraft paper bags (with PE inner liner), 25 kg corrugated cartons, 500 kg and 1,000 kg supersacks (bulk bags/jumbo bags), and bulk liquid in ISO tanks or flexitanks (for molten delivery to large-volume buyers). The choice of packaging depends on order volume, downstream handling capability, and storage conditions. We recommend supersacks for mid-volume industrial buyers and bulk liquid for large-scale soap or oleochemical manufacturers.

Yes. Bio Green Wax offers RSPO-certified palm stearic acid under Mass Balance (MB) and, subject to availability, Segregated (SG) supply chains. RSPO credit certificates (eRTRs) are available for Mass Balance volumes. Segregated certified material is available for buyers with traceable sustainability commitments. RSPO certification is increasingly required by European cosmetics and personal care brands sourcing palm-derived ingredients. We also offer ISCC+ certification for buyers targeting EU sustainability regulation compliance. Documentation is provided at shipment.

Our palm stearic acid is supplied with a moisture content of less than 0.2% and a total impurity level below 0.5%, ensuring clean, consistent quality for all applications. For pharmaceutical-grade material, moisture specifications are tighter at less than 0.1%. These parameters are tested at production and confirmed in the CoA. Excess moisture in stearic acid can cause saponification, discolouration, and processing problems in downstream applications. Bio Green Wax maintains rigorous quality control at source and during packaging to deliver product within specification.

Yes. Palm stearic acid is a cornerstone ingredient in cosmetic emulsification — functioning as an emulsifier, thickener, and consistency factor in creams, lotions, body balms, and stick formulations. Bio Green Wax supplies cosmetic-grade palm stearic acid (double and triple-pressed) with full INCI documentation (INCI name: Stearic Acid), EU Cosmetics Regulation compliance, and Halal/Kosher certificates. We also provide safety data sheets and can support EU CPSR submission documentation. Contact our cosmetics sector sales team for a quotation and technical support.

For pharmaceutical applications, Bio Green Wax supplies palm stearic acid meeting USP (United States Pharmacopeia) and BP/EP (British/European Pharmacopoeia) monograph specifications for Stearic Acid. Certifications and documentation available include: CoA with full pharmacopoeial testing, GMP compliance statement, Halal certification, Kosher certificate, TSE/BSE-free declaration, and heavy metals test report.

For excipient buyers in regulated pharmaceutical markets, we can provide an Excipient Information Package (EIP) on request. Please share your pharmacopoeial grade and country of use when enquiring.

Yes. Bio Green Wax supplies palm stearic acid conforming to both the USP (Stearic Acid, NF) and BP/EP (Stearic Acid Ph. Eur.) monographs, including the required limits on acid value, iodine value, congealing point, unsaponifiable matter, and heavy metals. Pharmaceutical-grade stearic acid from Bio Green Wax is manufactured under GMP-controlled conditions and is widely used as a tablet lubricant, suppository base component, and topical excipient. Contact our pharmaceutical sector team for grade-specific documentation and compliance support.

Our double-pressed palm stearic acid has a melting point of 54–57°C, while triple-pressed grades melt at 58–62°C. Colour on the Gardner scale is typically Gardner 1–3 for double-pressed and Gardner 1 or below for triple-pressed, delivering a white to off-white appearance in solid form. Colour is an important quality indicator for cosmetics and soap manufacturers where end-product whiteness is essential. All colour and melting point specifications are confirmed in the CoA for each batch. Colour-sensitive buyers should specify their maximum Gardner value when placing orders.

Yes. Palm stearic acid serves as an effective internal and external lubricant and release agent in PVC, rubber, and thermoplastic processing. In PVC extrusion and injection moulding, stearic acid reduces friction between polymer chains and between the compound and processing equipment, improving flow and surface finish. Bio Green Wax supplies commercial-grade palm stearic acid for plastics and rubber processing, with competitive pricing for industrial-scale buyers. Please contact our industrial sales team with your consumption volume and technical requirements for a tailored supply quotation.

Lead times for palm stearic acid depend on destination: for South and Southeast Asian markets (India, Indonesia, Philippines), typical lead times are 2–4 weeks. For Middle East and African markets, 3–5 weeks. For European destinations, 4–6 weeks from booking confirmation. Packed (bagged) orders can typically be dispatched within 1–2 weeks from our inventory positions. Long-term contract customers receive priority allocation and fixed shipment scheduling. Please share your required delivery window and port of destination when requesting a quotation so we can confirm an accurate lead time.

Yes. For premium toilet soap and luxury bar soap applications, Bio Green Wax can supply triple-pressed palm stearic acid with an iodine value below 2.0 g I2/100g, indicating near-complete saturation and maximum palmitic/stearic acid purity. Low IV stearic acid produces harder, whiter, and more stable soap bars with enhanced lather quality and rancidity resistance. This grade is also preferred for pharmaceutical and high-end cosmetic applications where unsaturated fatty acid contamination must be minimised.
