Dimethicone Crosslinked Polymer(CAS 68937-55-3)
Dimethicone Crosslinked Polymer is a high-performance three-dimensional cross-linked silicone elastomer synthesized by special polymerization and cross-linking process, compounded with low-viscosity dimethicone carrier.
Different from linear ordinary dimethicone with single lubricating effect, this cross-linked elastic polymer has a unique three-dimensional network spatial structure, featuring excellent elasticity, ductility and structural stability.
It can instantly upgrade the formula skin feel to velvet silky texture, effectively eliminate greasy and sticky feeling of oil-phase formulas, and form a uniform, non-occlusive and smooth protective film on the skin surface.
With physical micro-rough structure and light refraction effect, it delivers natural soft-focus matte effect, blurs pores and fine lines without flat and fake finish. In formula systems, it plays multiple roles in thickening, anti-settling, anti-caking and system stabilization, significantly improving the suspension stability of powder and pigment components. With ultra-mild inert silicone properties, non-irritation, non-comedogenic and excellent oil-water compatibility, it is the core skin-feel upgrading raw material for high-grade matte clean beauty and silky smooth cosmetic products.
Key Benefits
• Exclusive Velvet Silky Skin Feel, Zero Greasiness: Unique elastic network structure brings soft and waxy velvet touch, completely improves the greasy and sticky defects of traditional oil-based formulas, realizes dry and smooth upper skin feel, and upgrades product grade in all dimensions.
• Natural Soft-focus Matte, No Flat Fake Finish: Micro-network structure produces uniform light refraction, naturally blurs pores and fine lines, reduces skin surface gloss, creates high-grade translucent matte texture, avoiding dull and flat makeup effect.
• Multi-functional Formula Stabilization: It has excellent thickening and rheological adjusting properties, effectively prevents powder settling and caking, improves formula uniformity and suspension stability, simplifies compounding process and reduces batch difference.
• Breathable Non-occlusive, Comfortable Long-term Wear: The elastic film layer has micro-breathable gaps, no tightness or stuffy skin, locks skin moisture without dry rebound, balances matte texture and skin comfort, suitable for all-day long-wear scenarios.
• Strong Compatibility & Wide Applicability: Perfectly compatible with silicone oil, ester oil, emulsified system and various cosmetic functional additives, stable performance in wide pH and temperature range, no flocculation or delamination.
• Inert & Safe, Clean Beauty Compliant: High-purity silicone inert polymer, non-irritating, low allergenic, non-comedogenic, no residual solvent, compliant with international clean beauty and cosmetic safety standards.
Applications
• Matte Long-wear Base Makeup: Velvet matte foundation, oil-control cushion compact, long-lasting BB/CC cream, pore-blurring makeup primer, nude makeup base products.
• Refreshing Skincare Series: Silky smoothing lotion and cream, oil-control refreshing emulsion, non-greasy moisturizing essence, skin finishing skincare products.
• Soft-focus Color Cosmetics: Matte blush, contour shadow, soft-focus eye shadow, velvet lip glaze, non-stick color cosmetic formulas.
• Non-greasy Sunscreen & Isolation: Refreshing matte sunscreen lotion, oil-free isolation cream, outdoor long-acting UV protection products.
• Fluffy Styling Hair Care: Fluffy anti-oil dry shampoo, matte hair styling lotion, smooth anti-frizz hair finishing products.

Frequently Asked Questions (FAQ)
• Q1: What is the difference between cross-linked dimethicone and ordinary linear silicone oil?
A1: Ordinary linear dimethicone only provides single lubrication and moisturizing effect with greasy risk; cross-linked dimethicone polymer has a three-dimensional elastic network structure, focusing on velvet matte skin feel, soft-focus blurring and formula stabilization. It eliminates greasiness, improves powder suspension, and has irreplaceable advantages in upgrading cosmetic texture.
• Q2: What is the recommended formula addition ratio?
A2: 2%-6% for matte base makeup, 1%-4% for refreshing skincare products, 3%-8% for soft-focus color cosmetics, 1%-3% for oil-free sunscreen, 2%-5% for hair styling products, adjustable according to formula matte degree and skin feel requirements.
• Q3: Will it cause powder floating or uneven dispersion?
A3: No. The product has ultra-high system compatibility, can be quickly and uniformly dispersed in oil phase and emulsified systems, effectively improves powder ductility and suspension, prevents pigment settling and caking, and makes formula texture more delicate and stable.
• Q4: Is it suitable for oily and sensitive skin formulas?
A4: Absolutely suitable. It features zero greasiness and breathable non-occlusive film formation, regulates skin oil balance without clogging pores or causing stuffy skin. The inert silicone material is mild and non-irritating, perfectly matching oily skin refreshing formulas and sensitive skin mild care systems.
• Q5: How does it improve long-wear makeup effect?
A5: It forms a smooth and elastic protective film on the skin surface, which fits closely with the skin texture, resists daily friction and slight sebum erosion, effectively delays makeup floating and fading, maintains long-term matte and clean skin state, and improves overall makeup durability.
• Q6: Does it support stable bulk supply and technical services?
A6: Standardized cosmetic grade production with stable network structure, skin feel performance and dispersion, sufficient inventory, supports long-term bulk supply and global export, and provides professional formula debugging, matte velvet skin feel customization and system stability optimization technical support.
