In personal care formulation (skincare, makeup, haircare, sun care, antiperspirant/deodorant), "lightness" and "long-lasting effect" are a hard-to-balance pair. Traditional oils (mineral, vegetable) are heavy, pore-clogging, and greasy. Early volatile silicones (D4/D5) give instant freshness but evaporate too fast, leaving no lasting conditioning. With tightening regulations on lower cyclomethicones, sourcing a "hexamer-based, low-volatility long-lasting, non-greasy, traceless, highly compatible" cyclic volatile silicone has become the core proposition for personal care upgrade.
Addressing this,
Anhui IOTA Silicone Oil Co., Ltd. officially launches
Dodecamethylcyclohexasiloxane IOTA D6 (Alias: Cyclohexasiloxane; CAS 540-97-6; EINECS 208-762-8). Characterized by "colorless transparent liquid, odorless, non-irritating, D6≥92%, (D5+D6)≥95%, water≤0.025%, Hazen≤20, 190kg/drum", backed by "cyclic hexamer + low-volatility long-lasting + silky traceless", it is the "clarity" choice for personal care spreading and skin-feel modulation.
Molecular Architecture: Hexamer Ring + 12 Methyl Symmetry + Low Surface Tension
-
Hexamer Ring Backbone: Six (CH₃)₂SiO units forming a cyclic structure, providing unique volatility and low surface tension, distinct from non-volatile linear silicones.
-
12 Methyl Symmetry: Two methyls per silicon create a uniform hydrophobic film, delivering silky, dry touch without greasiness.
-
Low-Volatility Long-Lasting: As a hexamer, moderate MW, lower evaporation rate than lower oligomers, longer skin/hair residence time for continuous conditioning — "long-lasting clarity".
Performance Leap: From "Flash Evaporation" to "Long-Lasting Clarity"
-
Non-Greasy Freshness: Volatile, no residue, non-pore-clogging, soft silky feel on skin/hair.
-
Low-Volatility Long-Lasting: Slow evaporation, extended residence time, continuous conditioning.
-
Broad Compatibility: Compatible with waxes, fatty acids, esters, mineral oil, non-volatile silicones, absolute ethanol — high formulation flexibility.
-
Pigment Dispersion Aid: Lowers surface tension, assists solid pigment dispersion in color cosmetics.
-
Excellent Spreadability: Easy spreading and application.
Application Penetration: From Skincare to Color Cosmetics
-
Skincare & Sun Care: Light spreading, reduces sunscreen greasiness, improves application experience.
-
Color Cosmetics: Assists pigment dispersion, silky texture, prevents caking.
-
Hair Care: Silky, dry hair feel, non-greasy, easy combing.
-
Antiperspirant/Deodorant: Evaporative cooling, fresh feel, compatible with actives.
IOTA Technical Guide: Wide Compatibility, Cool & Shaded Storage
-
Formulation: Use alone or blended. Compatible with various cosmetic ingredients. Determine usage per formulation needs.
-
Taboo: Store in ventilated, cool place. Prevent rain and sun exposure.
-
Storage: 190kg/drum; routine handling.
Industry Insight: With evolving global regulations on cyclic silicones, D6's value in personal care continues to grow. Its "low-volatility long-lasting conditioning - traceless spreading" mechanism is well validated. IOTA D6, with "D6≥92% + long-lasting + non-irritating",
fills the key supply chain link for domestic high-purity cyclohexasiloxane in personal care, providing an import-substitution solution. This confirms domestic personal care silicones are leaping toward "hexamer long-lasting cyclic silicones", with growing technical say in high-end daily chemical silicones.
