Microcrystalline Wax — Frequently Asked Questions

Bio Green Wax Ltd supplies microcrystalline wax across three melting point grades: 65–70°C (soft grade) for cosmetics, adhesives, and candle blending; 70–80°C (medium grade) for rubber processing, coatings, and packaging; and 80–90°C (hard grade) for industrial coatings, bitumen modification, and high-temperature applications. All grades are available in slab, pastille, and prilled forms. Contact our sales team at sales@biogreenwax.com to discuss which grade best suits your production requirements.

Our microcrystalline wax has an oil content of 1–5% depending on grade, which contributes to its flexibility and adhesion characteristics. Needle penetration at 25°C (ASTM D1321) ranges from 3–30 units — harder grades show lower penetration values confirming greater rigidity. Grade-specific oil content and penetration values are confirmed in the batch Certificate of Analysis provided with every shipment, supporting your quality management and formulation documentation.

The minimum order quantity for microcrystalline wax is 500 kg, making it accessible to both mid-size manufacturers and large industrial users. Full container load quantities of 15–20 MT attract the most competitive pricing per tonne. We also offer trial samples for qualified buyers undertaking formulation development.

Full compliance documentation packages — including Certificate of Analysis, SDS, and pharmacopoeia compliance statements — are provided to support your EU Cosmetics Regulation (EC 1223/2009) and pharmaceutical regulatory submissions.

Our microcrystalline wax has a kinematic viscosity of 10–25 cSt at 100°C (ASTM D445), significantly higher than paraffin wax at the same temperature — a key technical differentiator that contributes to its superior adhesion and flexibility in adhesive and coating formulations. Saybolt colour is +20 to +28 for pharmaceutical and food-contact grades (near-white to water-white appearance). Batch-specific viscosity and colour data are confirmed in the technical data sheet and Certificate of Analysis accompanying every shipment.

Yes. Microcrystalline wax is a high-performance component in hot-melt adhesive systems, where it improves flexibility, tack, open time, and adhesion to difficult substrates including polyethylene, polypropylene, and metallised films. It is particularly valued in packaging hot-melts, bookbinding adhesives, and pressure-sensitive adhesive formulations. Soft and medium grades (65–80°C melting point) are most commonly specified. Bio Green Wax Ltd can supply alongside Fischer-Tropsch or PE wax for complete hot-melt wax ingredient packages — contact us to discuss your formulation requirements.

Yes. Cosmetic-grade microcrystalline wax from Bio Green Wax Ltd is a key structuring and thickening ingredient in lipsticks, mascaras, eyebrow pencils, stick deodorants, and emollient balms. It provides body, gloss, and stability to anhydrous cosmetic formulations. Full INCI compliance documentation (INCI name: Microcrystalline Wax), EU Cosmetics Regulation (EC 1223/2009) compliance statements, PAH test reports, and Safety Data Sheets are provided as standard. Contact us to request samples for your cosmetic formulation lab.

Bio Green Wax Ltd supplies microcrystalline wax in three packaging formats: slab form in 25 kg cartons (suitable for manually processed batches), pastille/prilled form in 25 kg bags or 500 kg supersacks (preferred for pharmaceutical, cosmetic, and automated production applications due to accurate dosing and faster melting), and bulk liquid for very large-volume industrial users. Pastille form is recommended for most B2B buyers as it reduces melt time and improves batch consistency. Specify your preferred format when requesting a quotation.

Yes. Soft-grade microcrystalline wax (65–75°C melting point) is widely used in B2B candle manufacturing at 2–5% addition to paraffin wax blends to improve flexibility and reduce surface cracking, improve adhesion of wax to glass containers in jar candles, enhance fragrance oil retention, and reduce white bloom and improve surface appearance. Bio Green Wax Ltd can supply alongside our fully refined paraffin wax range for a complete candle wax ingredient solution. Contact us for technical data sheets and blend ratio recommendations.

Soft-grade microcrystalline wax (melting point 65–70°C, needle penetration 20–30) is flexible and slightly tacky — ideal for cosmetic formulations, hot-melt adhesives, and candle blending where pliability is needed. Medium grade (70–80°C, penetration 10–20) balances hardness and flexibility for rubber processing, coatings, and packaging applications.

Hard grade (80–90°C, penetration 3–10) is the most rigid, suited to industrial coatings, paper lamination, bitumen modification, and high-temperature processing. Choosing the right grade for your application significantly affects end-product performance — our technical team is available to advise.

Yes. Microcrystalline wax is used in rubber compounding as a processing aid and anti-ozonant — it migrates to the surface of vulcanised rubber to form a protective barrier film inhibiting ozone cracking, a critical performance requirement for automotive and industrial rubber products. In bitumen and asphalt modification, hard-grade microcrystalline wax improves high-temperature performance and rutting resistance of road surfaces.
