Product Overview & Basic Characteristics

Microcrystalline Wax (Slack Wax) is a type of crystalline wax with a fine, dense molecular structure, distinguished by its white or pale yellow appearance and a controlled melting point range of 70℃ to 77℃. Unlike ordinary paraffin wax, it features a more compact crystalline structure, which endows it with superior hardness, toughness, and adhesion. Our microcrystalline wax is produced through advanced refining processes, ensuring high purity, uniform texture, and no impurities or unpleasant odors—meeting the strict quality requirements of cosmetics, candle making, and rubber industries. It presents as a solid block, with good structural stability at room temperature, resisting crumbling, deformation, or sticking during storage, transportation, and handling. The 70-77℃ melting point range strikes an optimal balance between processability and performance, making it easy to melt under controlled heating while maintaining stable functionality in various application scenarios.

Core Application I: Candle Making

Microcrystalline Wax is a valuable additive and blending component in candle making, significantly enhancing the quality and performance of finished candles. Its moderate melting point (70-77℃) ensures compatibility with common candle waxes such as soy wax, palm wax, and paraffin wax, enabling flexible formula adjustment. When blended into candle formulations, it effectively increases the candle’s hardness and shape retention, preventing softening, sagging, or deformation even in slightly warm environments. It also improves the candle’s surface smoothness, eliminating unevenness or blemishes and enhancing aesthetic appeal. A key advantage is its ability to reduce candle dripping during burning, minimizing waste and fire hazards while extending the burning time. Additionally, it enhances fragrance retention, helping candles lock in essential oils or fragrance oils and release a long-lasting, uniform aroma. Suitable for all types of candles—including jar candles, pillar candles, taper candles, and decorative candles—it is widely used by commercial candle manufacturers and DIY enthusiasts alike.

Core Application II: Cosmetics Industry

In the cosmetics industry, microcrystalline wax is a widely used functional raw material, valued for its excellent moisturizing, thickening, and emulsifying properties. Its mild, non-toxic, and hypoallergenic characteristics make it safe for use in various cosmetic products, including lipsticks, lip balms, creams, lotions, and hair care products. As a moisturizer, it forms a thin, breathable protective film on the skin and lips, locking in moisture and preventing water loss, effectively improving dryness and roughness. As a thickening agent, it adjusts the consistency of cosmetic formulations, giving products a smooth, creamy texture that is easy to apply and absorb. In lipsticks and lip balms, it enhances texture and shape retention, preventing melting or breaking at room temperature while providing a comfortable, non-greasy feel. It also acts as an emulsifier, helping to blend oil-soluble and water-soluble ingredients, ensuring formulation stability and extending product shelf life. Its compatibility with other cosmetic ingredients (such as oils, fragrances, and pigments) makes it a versatile choice for cosmetic manufacturers.

Core Application III: Rubber Protection

Microcrystalline wax plays a crucial role in rubber protection, serving as an effective anti-aging and protective agent for rubber products. Rubber products are prone to aging, cracking, and hardening due to exposure to sunlight, oxygen, temperature changes, and moisture—reducing service life and performance. Our microcrystalline wax addresses this issue by penetrating into the rubber matrix and forming a protective film on the surface. This film blocks UV radiation and oxygen, slowing down the oxidation process and delaying rubber aging. It also improves the rubber’s flexibility and toughness, reducing brittleness and cracking, even in harsh environmental conditions. Additionally, it enhances the rubber’s water resistance, preventing moisture absorption and corrosion, and improves processing performance during rubber production. Suitable for all types of rubber products, including tires, seals, hoses, and rubber accessories, it extends product service life, reduces maintenance costs, and ensures reliable performance in industrial and daily use scenarios.

Physical & Chemical Properties & Stability

The excellent performance of microcrystalline wax is supported by its superior physical and chemical properties. Its melting point ranges from 70℃ to 77℃, which is higher than many common candle waxes, ensuring stable performance in high-temperature environments while remaining easy to process with standard heating equipment. It has high hardness and toughness, good adhesion, and excellent flexibility, making it suitable for diverse application needs. Chemically, it is stable, resisting oxidation, hydrolysis, and rancidity when stored properly, ensuring a long shelf life and consistent performance over time. It is insoluble in water but compatible with various organic solvents, oils, and waxes, enhancing its adaptability in different formulations. It also exhibits good thermal stability, melting smoothly without decomposition or harmful gas emission, ensuring safety during processing and use. Its uniform composition and consistent performance guarantee reliable results in every application, whether in cosmetics, candle making, or rubber protection.
