Boron Nitride

Product Description

As a premium functional mineral sourced directly from our state-of-the-art manufacturing facility, our high purity Boron Nitride offers exceptional quality for global cosmetic formulations. Its unique hexagonal crystalline lattice structure provides excellent lubricity and high thermal conductivity, facilitating a superior soft-focus effect that optically blurs skin imperfections while remaining perfectly compatible with formulations engineered for active transdermal delivery. This versatile texturizer aligns seamlessly with clean beauty and high-performance makeup market trends, can be surface-modified to remain stable in aqueous solution suspensions, and serves as an indispensable additive to elevate premium cosmetics with luxurious skin adhesion and a long-lasting matte finish.

Key Benefits & Applications

Our premium grade Boron Nitride delivers exceptional optical and texturizing efficacy for professional cosmetic systems:

• Optical Soft-Focus Blurring: Diffuses light effectively across the skin surface via planar micro-structures to visually minimize the appearance of fine lines, pores, and cutaneous imperfections.
• Sebum Absorption & Mattification: Demonstrates high oil absorption capacity, ensuring long-lasting sebum control and anti-caking properties in oily skin formulations.
• Enhanced Skin Adhesion & Slip: Provides an ultra-silky, velvety tactile profile and significantly increases the wear-time of color cosmetics due to its planar crystal alignment.
• Broad Application Spectrum: Extensively utilized in loose powders, pressed foundations, primers, sunscreens, and luxury anti-aging formulations to improve spreadability.

Formulation Guidelines

• Suggested Usage Level: 1.0% - 10.0% depending on the specific product type (can be used up to 40.0% in advanced powder cosmetics).
• Dispersibility: Hydrophobic and lipophilic nature; completely insoluble in water and oil, but easily disperses in the oil phase or powder phase during processing.
• Thermal Stability: Exceptionally stable in high-temperature processing, maintaining structural integrity across all standard cosmetic manufacturing temperatures up to 80°C.
• Process Incorporation: For liquid or emulsion systems, premix with oils or low-viscosity esters before homogenization to ensure uniform particle partition.
• Synergy: Combine with Lauroyl Lysine to enhance skin affinity, create talc-free clean beauty formulations, and improve long-wear water resistance.
