For advanced material solutions, explore our range of Bulk Cosmetic Mica Powder.

Precision Technical Specifications for Cosmetic Grade Mica

High-performance cosmetic mica is not merely a shimmer agent; it is a meticulously engineered pigment system. Our bulk cosmetic mica powders are manufactured to stringent physical and chemical parameters, ensuring optimal integration and performance within diverse cosmetic matrices.

• Particle Size Range: Our standard cosmetic grade mica powders are available in a precisely controlled particle size distribution ranging from 0.05mm (50 microns) to 3.0mm (3000 microns). This broad spectrum, equivalent to 1/128" to 1/8", allows for tailored optical effects, from subtle sheen to dazzling glitter-like brilliance, ensuring excellent sensory profiles and functional dispersion.
• Carrier Substrate Technology: We utilize advanced carrier substrates to meet evolving industry demands. Options include:
  • Regenerated Cellulose: A premium, biodegradable alternative offering excellent sustainability credentials without compromising optical performance.
  • PET (Polyethylene Terephthalate): For applications requiring maximum brilliance, exceptional solvent resistance, and economic viability. Our PET-based micas are engineered to be compliant with non-microplastic definitions where applicable.
  • Synthetic Mica: A highly pure, synthetic fluorphlogopite substrate providing superior color purity, enhanced reflectivity, and chemical inertness compared to natural mica, especially crucial for sensitive skin formulations or specific color requirements.
• Thermal Stability: Our cosmetic grade mica powders exhibit exceptional thermal stability. They are engineered to withstand processing temperatures up to 160°C - 200°C without degradation in color, luster, or structural integrity. This ensures compatibility with a wide array of manufacturing processes, including hot-pours, baking, and high-temperature dispersion methods.
• Solvent Resistance Profile: Robust solvent resistance is paramount for product stability and longevity, particularly in challenging formulations:
  • Nail Lacquer Systems: Our mica powders demonstrate verified resistance to common nail lacquer solvents, including ethyl acetate and butyl acetate, preventing pigment bleed, color shift, or dissolution, thus maintaining formula integrity and visual appeal.
  • Water/Glycol Emulsions: Engineered for stability in aqueous and hydroalcoholic systems, our mica maintains its dispersion and color fidelity within water-in-oil, oil-in-water, and glycol-based emulsions, preventing clumping or premature settling.

Rigorous International Regulatory Compliance Guidance

Navigating global cosmetic regulations is complex. MLM Cosmetic prioritizes compliance, providing robust documentation and testing to support your product's market entry worldwide.

• EU Regulation 1223/2009 & Annex XVII Microplastic Restriction: Our mica products are rigorously evaluated against the European Chemicals Agency (ECHA) definition of microplastics. We provide clear substantiation and compliance statements, particularly for regenerated cellulose and synthetic mica variants, ensuring your formulations avoid the upcoming microplastic bans within the EU. PET-based micas are carefully manufactured and classified to comply with particle size and solubility criteria for non-microplastic designation where permissible by specific application guidance.
• US FDA MoCRA Ingredient Safety Substantiation: For the US market, our mica powders are supported by comprehensive safety data and compliance documentation in line with the Modernization of Cosmetics Regulation Act of 2022 (MoCRA). This includes ingredient listings, Certificates of Analysis (CoA), and safety assessments to aid in your product's responsible person registration and substantiation requirements.
• Heavy Metal ICP-MS Testing Limits: We adhere to industry-leading strict limits for heavy metal impurities, verified through Inductively Coupled Plasma – Mass Spectrometry (ICP-MS) testing for every batch. Our typical maximum limits are:
  • Lead (Pb): < 2 ppm
  • Arsenic (As): < 1 ppm
  • Mercury (Hg): < 1 ppm
  • Cadmium (Cd): < 1 ppm These limits are significantly below stringent international regulatory thresholds, safeguarding consumer health and product integrity.

Competitive Gap Analysis: Addressing Formulation Challenges

Many formulators encounter common issues with lower-grade mica powders that compromise product quality and market viability. MLM Cosmetic proactively addresses these.

• Formulation Suspension Settling: Inferior mica often suffers from poor surface treatment or inconsistent particle density, leading to rapid settling in low-viscosity systems. Our mica powders feature optimized surface coatings and tightly controlled particle size distributions, designed for enhanced suspension stability and homogeneous dispersion, minimizing settling and maximizing shelf-life appeal.
• Solvent Bleeding & Discoloration: Unstable pigments can leach color into the surrounding cosmetic matrix (solvent bleeding) or lose their vibrancy over time. Our advanced encapsulation and high-purity substrates ensure superior solvent fastness and UV stability, preventing these critical aesthetic and performance failures.
• Microplastic Ban Blind Spots: The global regulatory landscape, especially in the EU, is rapidly shifting against microplastics. Many suppliers offer legacy PET glitter or mica blends that will soon be non-compliant. MLM Cosmetic provides clear guidance and validated alternatives, such as regenerated cellulose and specific PET formulations, to ensure your product portfolio remains future-proof and compliant, avoiding costly reformulations or market withdrawal.
