In personal care formulations, traditional oils show poor spreadability, greasy feel and residue, tending to clog pores and cause comedones over time. Some volatile solvents improve spreadability but evaporate too fast, leaving short residence on skin or hair, failing to provide lasting silky feel, and potentially causing tightness or irritation by stripping surface moisture. In color cosmetics, solid pigment dispersion is difficult, requiring extra dispersants and resulting in heavy, non-breathable finish. Hair care products using heavy oils easily cause flatness and limpness. For specifications demanding "oil-free freshness, low-evaporation long residence, silky dry feel, easy spread, surface tension reduction, broad compatibility", a strictly controlled cyclohexasiloxane places sensory optimization and formulation compatibility at one carrier node. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. launches Dodecamethylcyclohexasiloxane IOTA-D6 (also named cyclohexasiloxane). Characterized by "colorless transparent liquid, odorless, non-irritating; color Hazen ≤20.0; D6 content ≥92.0%; (D5+D6) content ≥95.0%; moisture ≤0.025%; non-greasy fresh feel; low evaporation rate, long residence on skin/hair; good compatibility with various personal care ingredients; chemically stable; makes skin/hair silky and dry; reduces surface tension, assists solid pigment dispersion; good spreadability; used in skincare, sun care, color cosmetics, hair care, anti-perspirant/deodorant; 190kg/drum; store in ventilated cool place, prevent rain and sun exposure; brand IOTA", backed by "hexa-cyclic low-evaporation + oil-free silky + high-purity low-moisture", it serves as a volatile cyclo-silicone carrier for personal care. System Positioning: Hexa-Cyclic Siloxane Among Volatile Silicone Families Within volatile silicone families, IOTA-D6 is a hexameric cyclomethylsiloxane, distinct from D5 pentamer cyclosiloxanes (fast evaporation, short skin residence), linear volatile silicones (different spreadability and silky feel profile), and mineral oils/synthetic esters (greasy residue, non-volatile, comedogenic). IOTA-D6 uses a six-membered siloxane ring for lower evaporation rate and longer residence, and full methyl substitution for hydrophobic freshness and low surface tension. It positions as a shared volatile spreading carrier for "skincare/color cosmetics/hair care/anti-perspirant", rather than a functional active or occlusive oil. Molecular Architecture: Six-Siloxane Ring + Full Methyl Shell + Low Surface Tension + Low-Vol Long Residence IOTA-D6 is dodecamethylcyclohexasiloxane, a cyclic structure of six siloxane units, each silicon bonded to two methyl groups. The cyclic architecture imparts low surface tension, enabling easy spreading on skin/hair and assisting uniform pigment dispersion; the full methyl shell provides hydrophobicity, oil-free freshness and virtually no residue after evaporation; the hexamer molecular weight is higher than pentamer, giving lower evaporation rate and prolonged residence on substrates; high purity (D6 ≥92.0%, D5+D6 ≥95.0%) and ultra-low moisture (≤0.025%) ensure chemical stability, low irritation and batch consistency; color Hazen ≤20.0 guarantees clarity without affecting product appearance. Performance Leap: From "Greasy Residue, Fast-Evap Short Stay" to "Hexa-Cyclic Long-Retain Oil-Free Silky" With IOTA-D6, personal care formulations improve jointly: sensory—oil-free freshness brings soft, silky, dry feel to skin and hair; evaporation—low evaporation rate gives long residence, sustaining spreading and conditioning effects; compatibility—compatible with waxes, fatty acids, fatty esters, mineral oils, non-volatile silicone oils and absolute ethanol, enabling high formulation flexibility; stability—chemically inert, non-reactive with other ingredients; functionality—reduces surface tension, assists solid pigment dispersion, improving color cosmetic texture and uniformity; spreadability—enables easy application and film-forming, enhancing user experience. Application Penetration: From Skincare to Color Cosmetics, Hair Care and Anti-Perspirant IOTA-D6 covers four core scenarios. Skincare and sun care: replaces heavy oils as fresh base, improving spreadability and skin feel—emphasizing non-comedogenic oil-free texture; trial by formula. Color cosmetics: assists solid pigment dispersion, providing silky dry finish and reducing heaviness; trial by pigment ratio. Hair care: imparts soft silky feel without limpness—emphasizing long-residence conditioning; trial by hair-care system. Anti-perspirant and deodorant: volatile carrier for dry skin feel—emphasizing easy spread and quick film; trial by system. ⚠️ Taboo: store in ventilated cool place, prevent rain and sun exposure; specific dosage and method determined per formulation. IOTA Technical Guide: Broad Compatibility Blending, Trial by Formula, Cool Storage IOTA-D6 is a colorless transparent liquid in 190kg/drum. Compatible with waxes, fatty acids, fatty esters, mineral oils, non-volatile silicone oils and absolute ethanol; can be used alone or blended with other components. Specific dosage and method determined by individual formulation. Store in ventilated cool place, prevent rain and sun exposure; managed as general chemical. Industry Insight: Cyclosiloxane selection is not the faster evaporation the better, but using ring size for evaporation rate and residence time, purity for sensory and irritation, compatibility for formulation flexibility, and addition method for spreading and dispersion. For personal care formulators, IOTA-D6 uses one high-purity hexa-cyclic siloxane across skincare, color cosmetics, hair care and anti-perspirant, taking low-evaporation long-residence, oil-free silky and tension-reduction pigment-aid as batch-checkable anchors, reducing greasy residue, fast-evaporation and poor dispersion rework.
