In personal care formulation, traditional oils spread poorly with greasy feel; linear PDMS evaporates slowly leaving heavy residue; low-MW silicones migrate and reduce sunscreen/makeup durability; common volatile solvents have narrow compatibility with waxes and esters, limiting formulation freedom. For specifications demanding "cyclic siloxane moderate volatility + oil-free spread + broad compatibility + pigment dispersion + non-irritating", a strictly controlled cyclohexasiloxane places evaporation rate and sensory carrier at one siloxane node. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. launches IOTA D6 Cyclohexasiloxane (primarily single-component cyclic methylsiloxane hexamer). Appearance colorless transparent liquid, color ≤20, D6 content ≥92.0%, D5+D6 ≥95.0%, dry residue 150℃/3h ≤0.15%, acid value ≤0.01mg KOH/g, water ≤0.025%. Odorless non-irritating, easy spread, imparts soft lubricious feel to skin and hair, highly compatible with cosmetic ingredients, no residue after evaporation, reduces surface tension, aids pigment dispersion, excellent spreadability. Applications: skin care, sunscreen, make-up, hair care, antiperspirant, deodorant. Compatible with waxes, fatty acids, fatty acid esters, non-volatile silicones; miscible with alcohol; use singly or blended. Packaging: 190kg/drum. Store cool, dry, ventilated, lightless. Brand IOTA. System Positioning: Cyclohexasiloxane Among Volatile Silicone Families Within volatile silicones, IOTA D6 is a cyclic polydimethylsiloxane hexamer, distinct from cyclopentasiloxane (D5, faster flash-off, shorter skin feel), linear low-MW silicones (slow evaporation, residual film), isoalkanes (incompatible with silicones, dry feel), ester volatiles like neopentyl glycol dioctanoate (phase separation with silicones). IOTA D6 uses dodecamethylcyclohexasiloxane backbone for moderate evaporation—neither too fast like D5 nor too slow like linear oils—positioning as a multi-functional cyclic carrier for "skin care/sunscreen + make-up + hair care + antiperspirant/deodorant", rather than single solvent or pure oil substitute. Molecular Architecture: Cyclic Methylsiloxane Hexamer + D6 ≥92.0% + Dry Residue ≤0.15% + Acid ≤0.01 IOTA D6 core is cyclic hexamer siloxane structure, six-membered Si-O ring giving moderate polarity and ultra-low surface tension. D6 ≥92.0%, D5+D6 ≥95.0% ensure batch purity; dry residue ≤0.15% (150℃/3h) means near-zero after high-temp evaporation; acid value ≤0.01mg KOH/g and water ≤0.025% secure formulation stability and low irritation; color ≤20 maintains clarity; miscibility with alcohol, waxes, esters and non-volatile silicones grants wide formulation freedom. Performance Leap: From "Greasy Residue, Narrow Compatibility" to "Cyclic Volatility, Oil-Free Spread" With IOTA D6, seven-way synergy: oil-free feel—no oily film after evaporation, dry soft skin; volatility—moderate evaporation dwells on skin/hair for balanced residence and dry-down; compatibility—broad miscibility with waxes, fatty acids, esters, non-volatile silicones and alcohol; stability—ultra-low acid and moisture prevent rancidity and separation; sensory—low surface tension and excellent spread give lubricious clarity; pigment dispersion—aids uniform color payoff in make-up; safety—odorless non-irritating for sensitive skin. Application Penetration: From Skin Care to Make-Up, Hair Care and Antiperspirant IOTA D6 covers four scenarios.

• Skin care & sunscreen: creams, lotions, SPF—spread enhancement and feel; per total formula.
• Make-up: foundation, lipstick, eyeshadow—pigment dispersion and wear; trial per pigment load.
• Hair care: shampoo, conditioner, mask—lubricity and gloss; per system.
• Antiperspirant & deodorant: roll-on, spray, stick—carrier volatility and actives dispersion; per dosage form.

⚠️ Taboo: low irritation but avoid eye contact; store cool dry ventilated lightless; avoid heat, sun, prolonged open exposure causing evaporation loss; seal packaging. IOTA Technical Guide: 190kg/Drum, Cool Dry Ventilated Lightless Storage IOTA D6 in 190kg/drum. Use singly or blend with other cosmetic ingredients; miscible with alcohol for alcohol-based products; pre-heat disperse with waxes and esters before adding to oil or water phase. Fill clean container, store cool, dry, ventilated, lightless, sealed against evaporation. Industry Insight: Cyclic siloxane selection is not the faster evaporation the better, but using ring purity for batch stability, volatility window for sensory residence, acid/moisture for formulation safety, compatibility spectrum for formulation freedom. For personal care formulators, IOTA D6 uses one high-purity cyclohexasiloxane across skin care, make-up, hair care and antiperspirant, taking cyclic volatility and oil-free spread as batch-checkable anchors, securing evaporation rate and sensory experience simultaneously.
