Trimethylsiloxysilicate, MQ Silicone Resin-CAS 56275-01-5
Trimethylsiloxysilicate MQ Silicone Resin is a high-performance cross-linked silicone polymer formed by co-hydrolysis and polycondensation of monofunctional trimethylsiloxy groups and tetrafunctional silicate groups.
With unique rigid-flexible alternating M/Q molecular structure, it integrates high transparency, strong waterproof barrier, anti-sebum rub resistance and non-sticky shaping functions in one.
Different from polyurethane and plant polysaccharide film-forming agents, this product belongs to silicone-based functional resin, featuring extreme water repellency, excellent oil-sweat resistance and super abrasion resistance.
It can form a uniform, smooth, high-transparency and compact hydrophobic protective film on skin and hair surface, effectively isolating sweat, sebum and external friction.
In color cosmetics, it firmly locks color pigments to eliminate lipstick cup transfer, foundation fading and makeup smudging. In sunscreen formulas, it significantly improves water and sweat resistance of UV film, enhances SPF/PA durability, and prevents sunscreen failure caused by sweating and washing.
In hair styling products, it provides light and rigid shaping force without greasy residue or stiff texture. With excellent compatibility with various silicone oils and ester solvents, stable physical and chemical properties, no irritation and high safety, it is the core high-end functional raw material for waterproof long-wear makeup and durable sunscreen systems.
Key Benefits
• Extreme Waterproof & Sweat-resistant Barrier: Unique cross-linked hydrophobic molecular structure forms dense waterproof film, effectively resisting sweat and water erosion, solving the problem of easy makeup removal and sunscreen failure in humid environments.
• Super Anti-transfer & Rub-resistant: Excellent pigment locking and anti-migration ability, firmly binds cosmetic powder and color molecules, resists daily friction and contact rubbing, realizing zero-transfer long-lasting makeup effect.
• High-transparency Glossy Film-forming: Ultra-high light transmittance without whitening or fogging after film formation, optimizes surface light reflection, endows makeup and hair with natural high-gloss delicate texture.
• Light Non-sticky Dry Skin Feel: Different from oily film-forming resins, it forms dry and breathable protective film with zero greasy residue, refreshing and non-sticky all day long, maintaining natural skin and hair comfort.
• Enhanced Sunscreen Weather Resistance: Stabilizes UV filter system, improves the adhesion and durability of sunscreen film, effectively extends outdoor sun protection time and enhances anti-aging protection effect.
• Excellent Solvent Compatibility & Stability: Freely soluble in various silicone oils and organic esters, stable in extreme temperature environments, no stratification or precipitation, easy formula processing and long-term storage stability.
Applications
• Waterproof Long-wear Color Cosmetics: Non-transfer lipstick, high-gloss lip gloss, waterproof eyeliner/eyeshadow, long-lasting blush and contour makeup products.
• Sweat-proof Waterproof Sunscreen: Outdoor high-power sunscreen lotion, waterproof anti-sweat sunscreen cream, long-acting anti-UV sun protection formulas.
• Durable Base Makeup Products: Wear-resistant long-lasting foundation, anti-rub cushion compact, zero-transfer BB/CC cream, makeup fixing primer.
• Deodorant & Antiperspirant Series: Refreshing antiperspirant spray, body deodorant lotion, long-lasting sweat-control functional cosmetics.
• Light Hair Styling Products: Non-greasy styling spray, fluffy anti-frizz hair lotion, light rigid shaping hair care formulas.

Frequently Asked Questions (FAQ)
• Q1: What is the core advantage of MQ silicone resin over polyurethane film-forming agents?
A1: Polyurethane resins focus on wear resistance and flexible holding with slight water permeability; MQ silicone resin features absolute hydrophobicity, zero water permeability, stronger anti-sebum and anti-transfer performance, higher film transparency and drier skin feel. It is the preferred raw material for extreme waterproof and zero-transfer high-end makeup systems.
• Q2: What is the recommended formula addition ratio?
A2: 3%-8% for waterproof lip cosmetics, 2%-6% for long-wear base makeup, 2%-5% for outdoor sunscreen, 1%-4% for antiperspirant products, 2%-7% for light hair styling products, adjustable according to formula waterproof grade and gloss requirements.
• Q3: Will silicone resin film cause powdery or dry skin feel?
A3: No. The M/Q cross-linked structure balances hardness and flexibility. The formed film is dense and smooth without dry powder feeling, skin tightness or brittle peeling. It maintains natural skin comfort while ensuring waterproof and anti-transfer effects.
• Q4: Is it compatible with silicone and oil-phase systems?
A4: Excellent compatibility. It can be completely dissolved in volatile silicone oil, dimethicone and various ester oils, with uniform system and no precipitation or flocculation. It is specially suitable for oil-phase and anhydrous cosmetic formulas.
• Q5: Why can it improve sunscreen durability?
A5: It forms a continuous hydrophobic protective film on the skin surface, which can lock UV filters firmly, avoid active ingredient loss caused by water washing and sweat erosion, and stably maintain SPF/PA protection efficiency for a long time.
• Q6: Does it support stable bulk supply and technical services?
A6: Standardized high-end cosmetic grade production with stable batch softening point, film-forming performance and waterproof effect, sufficient inventory, supports long-term bulk supply and global export, and provides professional formula debugging, waterproof anti-transfer system optimization and high-gloss effect customization technical support.
