The Primary Role of Beeswax in Pharmaceutical Manufacturing Thickener and Hardening Agent Application: Primarily used in ointments and creams. Principle: Possessing a high melting point and hardness, beeswax added to oily or emulsified bases significantly increases their viscosity, transforming them from liquid or semi-solid to firmer solid or semi-solid states. This renders ointments easier to apply and less prone to leakage. Oil-in-Water Emulsifier Application: Used in preparing oil-in-water emulsions. Principle: Free fatty acids and higher alcohols present in beeswax facilitate stable mixing of oil and water phases, forming an ‘oil-in-water’ emulsion. Within this emulsion, minute water droplets are encapsulated by the oil phase. This matrix effectively locks in moisture, making it suitable for ointments with moisturising and protective properties that resist washing off. Scaffold Material for Sustained-Release Formulations Application: In certain sustained-release tablets or implantable formulations. Principle: Beeswax is insoluble in water but can be slowly eroded by bodily fluids. When drugs are mixed with beeswax to form solid dosage forms, the active ingredients must pass through the wax's pores or be released as the wax gradually dissolves/degrades. This achieves the objective of slow, sustained drug release.

The primary applications of industrial-grade microcrystalline wax are categorised and detailed as follows: 1. Fats and Lubricants Industry This represents one of the largest application areas for microcrystalline wax. Petroleum jelly: Serving as the principal thickener and gelling agent, it blends with high-viscosity mineral oils to form petroleum jelly's characteristic paste-like structure. This directly addresses your previous query. Greases: Within greases, microcrystalline wax functions as a thickener or modifier, enhancing adhesion, sealing properties, and water resistance. Rust Inhibitors: Microcrystalline wax can be formulated into solvent-based or emulsifiable rust-preventative oils/greases. It forms a soft, dense, and highly adherent protective film on metal surfaces, effectively isolating moisture and air to prevent corrosion. 2. Rubber and Tyre Industry Microcrystalline wax serves as a guardian in this sector. Physical Anti-Ageing Agent: This represents its most crucial function within rubber compounds. During rubber compounding, microcrystalline wax disperses uniformly. When vulcanised rubber products (such as tyres) develop microscopic ‘ozone cracks’ from bending and stretching during use, the wax slowly migrates to the surface, forming a thin, dense wax film. This layer effectively blocks ozone attack, significantly slowing rubber ageing and extending product lifespan. 3. Coatings, Paints and Inks Industry Utilised for its water resistance, gloss enhancement and flexibility. Polishing agents: Employed in floor waxes, automotive polishes, etc., to impart gloss and abrasion resistance. Coating modification: Incorporated into specialised coatings (e.g., marine paints, waterproof coatings) to enhance water resistance, flexibility, and chemical resistance. Printing ink additives: Used to improve ink abrasion resistance, scratch resistance, and provide anti-slip properties.

Micronized wax, through core-shell structure design and functionalisation, can significantly enhance the abrasion resistance of products such as coatings and inks. Below are specific application scenarios and mechanisms of action: Coatings Sector Acrylate Micronized wax, via core-shell structure design, enhance coating scratch resistance. The core layer provides mechanical strength, while the shell layer, through functionalisation, reduces surface friction coefficients and disperses external impact forces, resulting in over threefold improvement in abrasion resistance. ‌ Ink Applications Polyethylene Micronized wax and fluorinated Micronized wax (e.g., PTFE) reduce printing friction wear through self-lubricating film formation and low friction coefficients. Their anti-adhesion properties prevent ink caking, thereby enhancing printing efficiency. ‌ Plastics Processing Polyethylene wax improves flow and dispersion in plastics, enhances surface hardness, and reduces friction loss. It is suitable for wear-resistant modification of engineering plastics.

Oxidized polyethylene wax is employed for viscosity adjustment in hot melt adhesives, primarily functioning through the following mechanisms: Viscosity Modulation: Within hot melt adhesives, oxidized polyethylene wax primarily functions as a viscosity modifier. Adjusting the wax dosage alters melt viscosity to accommodate diverse application requirements. For instance, during hot melt production, viscosity specifications tailored to specific applications—such as packaging or footwear bonding—are achieved by optimising flow properties and adhesion through precise wax addition. ‌ Process Adaptability: Hot melt adhesive viscosity must coordinate with process parameters such as curing time and wetting properties. Oxidized polyethylene wax balances the viscoelastic characteristics of the adhesive by regulating molecular alignment in the molten state, preventing application difficulties from excessive viscosity or oil bleeding from insufficient viscosity. ‌ Storage Stability: Possessing a narrow melting range and high softening point, this wax prevents agglomeration or separation in hot melt adhesives during storage caused by temperature fluctuations. Its antioxidant properties simultaneously extend the product's shelf life.

Key advantages of using Fischer-Tropsch wax for candle production: 1. Exceptional burning performance Smoke-free and odourless: This stands as one of Fischer-Tropsch wax's most notable attributes. Derived from natural gas or coal via the Fischer-Tropsch synthesis process, it boasts a pure composition with negligible impurities such as sulphur or nitrogen. Combustion produces no black smoke or unpleasant chemical odours, allowing the fragrance itself to be perfectly expressed. Complete combustion and high calorific value: The wax pool melts uniformly, enabling thorough burning with minimal residue, resulting in highly efficient wax utilisation. 2. Outstanding Physical Properties High Hardness, Significant Shrinkage: Fischer-Tropsch wax possesses a firm texture, making candles resistant to deformation and scratches. Its shrinkage rate is markedly greater than that of paraffin or soy wax, facilitating effortless demoulding. This results in smooth surfaces, sharp edges, and a premium texture in the finished product. High Melting Point: With a typical melting range of 90–105°C, Fischer- Tropsch wax far exceeds ordinary paraffin (approximately 60°C). This confers superior stability to candles in summer or high-temperature environments, resisting softening and deformation. 3. Exceptional Sensory Experience Snow-white and refined appearance: Fischer-Tropsch wax possesses a pristine white hue, unlike soy wax which carries a slight yellowish tint. This provides a pure “canvas” for colouring, enabling the creation of exceptionally vivid and accurate shades. Surface as smooth as porcelain: Once solidified, Fischer-Tropsch wax develops a distinctive lustre, with a texture reminiscent of ceramic or marble, lending it a remarkably premium visual appeal.

Core Functions Lubrication and Demoulding: Acts as an external lubricant during plastic processing, forming a lubricating layer at the mould-to-plastic interface to prevent adhesion and shorten moulding cycles. Improved Dispersibility: Optimises the uniform dispersion of pigments and fillers within plastics, reducing crystalline patterns and enhancing the aesthetic quality of finished surfaces. ‌ ‌Mechanical Strength Enhancement: When used in conjunction with calcium-zinc stabilisers, it can increase the impact strength of plastic products by 15 test units, making it suitable for applications demanding high toughness, such as window and door profiles. ‌ ‌Corrosion Resistance Protection: Forms an anti-corrosion oil film on metal mould surfaces, passing the 480-hour salt spray test standard. Ideal for high-demand applications like automotive plastic components. ‌

The most important role of Fischer-Tropsch wax in rubber. Migration and Film Formation: Fischer-Tropsch wax has limited compatibility with rubber. During rubber compounding and vulcanization, it disperses uniformly within the compound. However, during storage and use after vulcanization is complete, the wax gradually migrates from the interior of the rubber to its surface. Forming a protective layer: On the rubber surface, Fischer-Tropsch wax forms a dense, continuous, transparent physical protective film. Blocking ozone: This wax film effectively prevents environmental ozone from contacting the rubber surface, thereby shielding the rubber molecular chains from ozone attack. Why is this important? Ozone is the primary cause of “ozone cracking” in rubber products, especially those subjected to dynamic or static stretching. Cracking significantly reduces the service life and safety of rubber products. Products prone to ozone cracking: Tire sidewalls, door and window seals, cable jackets, rubber hoses, etc.
