Silica & Trimethylsiloxysilicate Blend（CAS 14808-60-7 / 56275-01-5）
Silica & Trimethylsiloxysilicate Blend is a high-performance composite silicon-based functional raw material formed by scientific proportioning and surface compounding of high-purity porous silica powder and cross-linked MQ silicone resin.
It perfectly integrates the core advantages of two classic cosmetic silicone materials: Trimethylsiloxysilicate provides dense hydrophobic film-forming performance, excellent waterproof, sweat-resistant and anti-transfer capabilities to lock makeup color and resist external friction; porous silica has strong oil absorption, uniform light refraction and soft-focus blurring effects, optimizing skin matte texture and pore concealing effect.
Different from single MQ resin (strong waterproof but slightly dry) and single silica (good matte but no waterproof fixing property), this composite material achieves a perfect balance of waterproof durability and breathable matte skin feel.
It can form a continuous, dense and breathable protective film on the skin surface, which can not only resist sweat, water and sebum erosion to avoid makeup fading and smudging, but also adsorb excess surface oil, blur pores and fine lines, and present natural high-grade velvet matte skin without dryness, tightness or mask-like fake finish. With stable composite structure, ultra-wide formula compatibility and ultra-mild safety, it is an upgraded core raw material for new-generation waterproof and matte long-wear clean beauty formulas.
Key Benefits
• Dual Advantages Integration, Zero Formula Defects: Combines MQ resin's waterproof anti-transfer performance and silica's oil-control soft-focus effect, solves the dryness defect of single silicone resin and the non-waterproof shortcoming of single powder, realizing one-material multi-effect upgrade.
• Waterproof & Sweat-resistant, Anti-rub Long-lasting Makeup: The dense silicone film layer effectively isolates water and sweat, firmly anchors pigment molecules, resists daily friction and contact rubbing, avoids cup transfer and makeup fading, and greatly improves makeup durability.
• Oil-control Soft-focus, High-grade Velvet Matte: Porous silica structure efficiently adsorbs sebum oil shine, with multi-angle light refraction to blur pores and fine lines, creates uniform and transparent matte skin texture, no flat fake white or dull finish.
• Breathable & Non-dry, Balanced Skin Feel: The composite system optimizes film density, retains skin air permeability while ensuring waterproof performance, locks basal skin moisture, avoids tight and dry skin caused by full occlusion, suitable for all-day long makeup.
• Excellent Formula Compatibility & Stability: Compatible with silicone oil, ester oil, powder and aqueous phase systems, uniform dispersion without agglomeration or precipitation, improves formula anti-caking and storage stability, simplifies compounding process.
• Ultra-mild & Wide Application: Inert silicon-based composite material, non-irritating, non-comedogenic and low allergenicity, compliant with clean beauty standards, suitable for sensitive skin and long-term daily cosmetic formulas.
Applications
• Waterproof Matte Long-wear Base Makeup: Matte waterproof foundation, oil-control long-lasting cushion, anti-sweat BB/CC cream, pore-blurring makeup primer, nude makeup base products.
• Zero-transfer Color Cosmetics: Non-stick cup matte lipstick, waterproof lip gloss, anti-rub eye shadow/eyeliner, long-lasting blush and contour cosmetics.
• Oil-control Setting Powder Series: Waterproof setting loose powder, matte pressed powder, oil-absorbing finishing powder, transparent long-wear powder products.
• Breathable Waterproof Sunscreen: Outdoor matte sunscreen lotion, sweat-proof isolation cream, long-acting UV protection skincare formulas.
• Matte Fluffy Hair Care Products: Anti-frizz matte styling spray, fluffy dry shampoo, non-greasy hair finishing lotion, long-lasting shaping hair care formulas.

Frequently Asked Questions (FAQ)
• Q1: What is the core advantage compared with single MQ resin or single silica?
A1: Single MQ resin has strong waterproof performance but tends to cause dry and tight skin with single matte effect; single silica has good oil-control soft-focus effect but lacks waterproof and anti-transfer capabilities. This composite blend integrates the strengths of both materials, achieving perfect matching of waterproof durability and breathable matte skin feel, with more balanced formula performance and wider application scenarios.
• Q2: What is the recommended formula addition ratio?
A2: 2%-6% for waterproof matte base makeup, 4%-12% for powder cosmetics, 1%-4% for breathable sunscreen, 2%-5% for oil-control skincare, 2%-7% for matte hair styling products, adjustable according to formula waterproof grade and matte soft-focus requirements.
• Q3: Will the composite material cause powder floating or caking?
A3: No. The product adopts professional surface composite modification technology with uniform particle dispersion and excellent compatibility. It will not agglomerate or precipitate in oil-phase, powder-phase and conventional aqueous systems, effectively improving powder ductility and makeup docility.
• Q4: Is it suitable for sensitive skin and long-wear daily makeup?
A4: Yes. The whole silicon-based inert composite system is non-irritating, low allergenic and non-comedogenic. The breathable film-forming structure avoids long-term skin occlusion, relieves dryness and tightness of traditional waterproof formulas, and is very suitable for sensitive skin and all-day long-wear cosmetic products.
• Q5: What is the unique formula value of this blend?
A5: It simplifies the compounding process of two single raw materials for customers, realizes one-step formula matching, solves the problem of unstable proportioning of manual compounding, and stably outputs dual effects of waterproof anti-transfer and oil-control soft-focus, greatly improving formula development efficiency and product finished product stability.
• Q6: Does it support stable bulk supply and technical services?
A6: Standardized high-end cosmetic grade composite production with stable batch ratio, particle size and functional performance, sufficient inventory, supports long-term bulk supply and global export, and provides professional formula debugging, waterproof matte system optimization and skin feel balance customization technical support.
