Polydimethyl Silicone Oil For Cosmetics And Personal Care

In the contemporary beauty and dermatological arena, Polydimethyl Silicone Oil (known internationally by its INCI designation Dimethicone) represents the undisputed gold standard in synthetic emollients, slip modifiers, and trans-epidermal barrier protectors. Characterized by its linear inorganic silicon-oxygen (Si-O-Si) backbone shielded by non-polar methyl side chains, Polydimethylsiloxane (PDMS, CAS Number: 63148-62-9) demonstrates an unparalleled synergy of physiological inertness, oxidative stability, chemical neutrality, and low surface tension (~20.5 to 22.0 mN/m).

As global cosmetic consumers demand lightweight, non-greasy, and multi-functional sensory textures, formulators are shifting rapidly toward strictly controlled, cosmetic-grade PDMS fluids. The modern industrial landscape is rigorously defined by regulatory compliance: European Union REACH regulations and global cosmetic safety directives mandate stringent control over residual cyclic siloxanes (specifically Octamethylcyclotetrasiloxane D4, Decamethylcyclopentasiloxane D5, and Dodecamethylcyclohexasiloxane D6) to levels strictly below 0.1% by weight. Hangzhou Bayee Chemical addresses this precision requirement through state-of-the-art continuous vacuum devolatilization and fractional molecular stripping, supplying pristine, high-viscosity-index fluids with virtually non-detectable cyclic impurities.

Based on strategic factories in Zhejiang, Jiangsu, Shandong, Anhui, Jiangxi, Hubei, Hunan, Hebei and Henan provinces etc, we export not only good quality products, competitive EXW costs, but also honesty, safety and international philosophies to customers. We work tightly with competitive production sites across whole China, who have special advantages, located in professional industrial areas, close to raw material bases, locally supplied with energy - gas or steam pipe connected with neighbour enterprises in same areas to reduce transportation costs.

Our factories have advanced ideas in technique crafts for higher yield production, unit consumption reducing from raw materials, also re-used the by-products for own downstream production for other products. By the way, we always keep close observation about raw material changing trend, react actively with factories shoulder by shoulder from organizing raw material at good times to secure more competitive production costs and share spaces with customers helping win their market shares. At the same time, we have wide connection with Chinese powerful chemical institute organizations for testing and supervising quality control in production process.
