In personal care formulations such as hand and body lotions, color cosmetics, sunscreens, moisturizing creams, emulsions and body washes, traditional oils or silicones often show poor compatibility with polar actives, causing phase separation or uneven active release; single low-viscosity polydimethylsiloxane spreads fast but resides too shortly on skin without anchoring actives; pure dimethiconol containing silanol groups is too viscous to disperse uniformly, causing graininess; some emulsion silicones contain extra surfactants that disturb formulation stability. For specifications demanding "enhanced active affinity, improved spreadability, high-purity low-cyclic, easy dispersion", a strictly controlled silanol-silicone solution places active delivery and sensory tuning at one carrier node. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. launches Dimethicone (and) Dimethiconol IOTA1403. Characterized by "silicone content ≥99%; dimethiconol (silicone gum) 12-14%; viscosity 4000mm²/s; flash point (closed cup) 135℃; appearance clear liquid; specific gravity (25℃) 0.93; solubility in water <0.1%; D4 content <2%; solution of high-viscosity dimethiconol in low-viscosity dimethicone; properties: increases affinity of other actives, good spreadability; applications: hand/body lotions, color cosmetics, sunscreens, moisturizing creams/emulsions, body wash; usage: add with high-speed stirrer after emulsification, homogenize to uniform cream; storage in original unopened container at ≤25℃; limitations: not for medical/pharmaceutical use, no injection, not edible; brand IOTA", backed by "silanol anchoring + PDMS spreading + high-purity low-D4", it serves as an active-affinity spreading agent for personal care. System Positioning: Silanol-Silicone Solution Among Personal Care Silicone Families Within personal care silicone families, IOTA1403 is a dimethicone and dimethiconol blend, distinct from pure polydimethylsiloxane (no silanol, weak polar active affinity), pure dimethiconol (extremely viscous, hard to disperse), emulsion silicones (contain surfactants that may interfere), and volatile cyclosiloxanes (no anchoring, only transient spreading). IOTA1403 uses high-viscosity silanol for hydrogen-bond anchoring to boost active affinity, and low-viscosity silicone for lubrication and spread. It positions as a shared affinity-spreading carrier for "skincare creams/color cosmetics/sunscreen/bath", rather than a mere lubricant or occlusive. Molecular Architecture: Silanol Anchor + Dimethylsiloxane Backbone + Dual-Viscosity + Low-D4 Purity IOTA1403 is a solution of high-viscosity dimethiconol dispersed in low-viscosity dimethicone. Silanol terminals (Si–OH) form hydrogen bonds or dipole interactions with polar actives like humectants, UV filters and botanical extracts, increasing affinity and uniform distribution; the polydimethylsiloxane backbone maintains low surface tension for excellent spreadability, enabling easy application and uniform film; silicone content ≥99% and D4 <2% control cyclic residues for eco-safety; specific gravity 0.93 (25℃) ensures lightness; viscosity 4000mm²/s balances flow and residence; water solubility <0.1% guarantees oil-phase stability; clear liquid appearance does not affect product color. Performance Leap: From "Poor Compatibility, Uneven Spread" to "Silanol Affinity, High-Visc Spread" With IOTA1403, personal care formulations improve jointly: affinity enhancement—silanol groups anchor actives for even distribution and synergistic release; spread optimization—PDMS matrix lowers surface tension, improving extensibility and reducing pilling; sensory tuning—high-purity silicone solution provides silky non-greasy feel, avoiding pure silanol tack; safety—D4 <2%, silicone ≥99% reduce impurities; flash point 135℃ closed cup for processing safety; process adaptability—clear liquid easy to pump and meter, recommended homogenization after emulsification for uniform dispersion. Application Penetration: From Hand Care to Color Cosmetics, Sunscreen and Bath IOTA1403 covers five core scenarios. Hand and body lotions: enhance humectant/soothing active affinity and spread—emphasizing dry silky feel; trial by formula. Color cosmetics: assist pigment dispersion and film uniformity—emphasizing adherence; sunscreens: improve UV filter spread and even coverage—reducing whitening; moisturizing creams/emulsions: sensory modifier and active carrier—enhancing absorption feel; body wash: provide lubricity during rinse and silicone deposition conditioning; recommended to add with high-speed stirrer after emulsification and homogenize. ⚠️ Taboo: store ≤25℃ in original unopened container; not for medical, pharmaceutical, injection or edible use; avoid prolonged contact with strong acids/bases. IOTA Technical Guide: Post-Emulsion Addition, High-Speed Disperse, Low-Temp Storage IOTA1403 is a clear liquid. Recommended to add after cream emulsification using high-speed stirrer, then homogenize to uniform. Dosage determined by formulation trial. Store in original unopened container at ≤25℃, away from heat (flash 135℃ closed cup). Managed as general chemical, not for drug or food use. Industry Insight: Silanol-silicone blend selection is not the more silanol the better, but using silanol ratio for affinity anchor density, base silicone viscosity for spread and residence, D4 content for purity safety, and addition process for dispersion uniformity. For personal care formulators, IOTA1403 uses one ≥99% silicone, D4<2% silanol-PDMS solution across hand care, color cosmetics, sunscreen, moisturizing and body wash, taking active affinity, high-viscosity spread and low-cyclic safety as batch-checkable anchors, reducing phase separation, uneven spread and tacky rework.
