In formulation systems of daily chemicals such as skin care, color cosmetics, sunscreen, perfume, and hair care, the selection of solvent and volatile siloxane carrier directly determines the product's spreadability, skin feel, evaporation rate, and ultimate safety. While traditional linear volatile methylsiloxanes (e.g., D5) are widely used, they still suffer from insufficient spreading efficiency, occasional residual feeling after evaporation, or less-than-dry skin feel in some high-end formulations; meanwhile, ordinary organic solvents often face risks of skin irritation, purity fluctuation, or poor chemical stability, failing to meet the escalating demands of "tear-free, low-sensitivity, safe, and residue-free" cosmetic upgrades. With escalating demands for "colorless odorless, low viscosity, high volatility, purity ≥99.9%, good safety" volatile methylsiloxanes, sourcing a key carrier with "branched hexasiloxane skeleton, tetradecamethyl full wrapping, 3.5mm²/s ultra-low viscosity" has become the core gap for domestic high-end cosmetic formulation localization. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. officially launches IOTA 20576 Branched Tetradecamethylhexasiloxane (Chemical Name: Tetradecamethylhexasiloxane; Alias: Branched tetradecamethylhexasiloxane). Characterized by "colorless odorless transparent liquid; viscosity 3.5mm²/s (25℃); purity 99.9%; flash point 75℃; boiling point 250℃; 200L plastic drum or 1000L IBC packaging; Class C warehouse storage; 24-month shelf life", backed by "branched hexasiloxane skeleton + tetradecamethyl full wrapping + 99.9% ultra-high purity + 3.5mm²/s low-viscosity fast evaporation", it serves as the "light escape choice" for daily cosmetic formulation and volatile solvent fields. Molecular Architecture: Branched Hexasiloxane + Tetradecamethyl Dense Planting + Low-Viscosity Fast Evaporation

• Branched Structure Reduces Viscosity & Enhances Evaporation: Unlike the regular arrangement of linear siloxanes, the branched structure breaks the close packing between molecular chains, significantly reducing intermolecular forces and resulting in a viscosity of only 3.5mm²/s at 25℃; meanwhile, the branched topology grants excellent volatility — rapidly spreading and evaporating on skin surface without oily residue, delivering an "dry and silky" instant skin feel.
• Tetradecamethyl Full-Wrap Stability: All substituents on the molecule are methyl groups, forming a fully methylated inert shell that grants extremely high chemical stability and safety; the steric hindrance of methyl groups protects the Si-O-Si backbone from external acid/alkali erosion, ensuring long-term stability in formulation systems without decomposition.
• 99.9% Ultra-High Purity Safety Assurance: Purity reaches 99.9%; the extremely low impurity content effectively eliminates the risk of skin allergy or irritation caused by trace cyclic residues or pyrolysis by-products, fully meeting the stringent purity requirements of daily chemicals and adapting to high-end safety formulations such as sensitive skin and infant products.

Performance Leap: From "Linear Residue" to "Branched Refresh"

• Refreshing Skin Feel: Ultra-low viscosity of 3.5mm²/s brings excellent fluidity and spreadability; a lightweight texture is felt instantly upon application, saying goodbye to stickiness.
• Fast Evaporation No Trace: As a volatile methylsiloxane, it completely evaporates in a short time without leaving an oil film on skin or hair, especially suitable for color cosmetics, sunscreens, and hair products requiring "dry matte" effects.
• Safe & Gentle: High chemical stability and good safety, gentle and non-irritating to skin, can be safely used as a solvent, broadening the application boundary in leave-on skin care products.
• Colorless & Odorless: Pure product is a colorless odorless transparent liquid, which will not interfere with the fragrance design and appearance of the formulation itself, giving perfumers and formulators maximum creative freedom.
• Wide-Temp Stability: Flash point 75℃, boiling point 250℃, remaining stable within conventional daily chemical production temperature ranges; non-flammable and non-explosive (Class C storage), high production safety.

Application Penetration: From Skin Care to Precision Solvent

• Daily Chemical Formulation (Main Battlefield): Skin care (skin feel modifier for serums, lotions, creams), color cosmetics (spreading carrier for foundations, lipsticks, eyeshadows), sunscreen (solvent and uniform dispersion medium for UV filters), perfume (volatile carrier for fragrances), hair care (fast-drying conditioner for hair oils and mousses).
• Volatile Solvent: As a high-purity, high-stability organic solvent for industrial scenarios requiring fast evaporation and no residue, such as precision cleaning, electronic coatings, and laboratory analysis.
• Formulation Conditioner: Acts as a compatibility bridge in complex emulsion systems, improving the compatibility of silicone oils with esters and waxes, preventing formula stratification or precipitation.

IOTA Technical Guide: Class C Warehouse, Light Handling to Prevent Damage

• Application: Add directly according to formulation needs, as solvent, volatile carrier, or skin feel modifier; typical addition amount depends on the formulation system, freely compatible with various cosmetic raw materials.
• ⚠️ Taboo: Store in Class C warehouse; handle with care during loading and unloading, prevent damage to packaging and containers; avoid contact with strong oxidants.
• Storage: 200L plastic drum or 1000L IBC drum packaging; shelf life 24 months; store in a cool and ventilated place, avoid direct sunlight and high temperature.
• Handling: Colorless odorless transparent liquid with extremely low viscosity (3.5mm²/s); prevent splashing during feeding; use up as soon as possible after opening to maintain high purity.

Industry Insight: The three core metrics of volatile methylsiloxanes — purity, viscosity, and evaporation rate — determine the skin feel and safety ceiling of daily chemical formulations. IOTA 20576, with "branched tetradecamethylhexasiloxane + 99.9% purity + 3.5mm²/s low viscosity + 75℃ flash point + Class C safe storage", fills the key supply chain link for domestic branched volatile siloxanes in high-end daily chemicals and precision solvents, providing a mass-producible quality raw material solution for downstream daily chemical enterprises. This confirms domestic functional siloxanes are leaping toward "branched controlled evaporation", with growing technical say in the cosmetic siloxane field.
