In the cosmetic silicone elastomer gel spectrum, the network structure of "cyclopentasiloxane (D5) carrier + PDMS crosspolymer / vinyl PDMS crosspolymer 3D skeleton + dimethiconol compatibilizer" and "NV 14-17%, visc 250,000-450,000cP (S94, 2.5RPM, 25℃), colorless translucent gel, 1-20% dosage" jointly dictate thickening boundary in W/O, W/Si, O/W and anhydrous systems, silky skin-feel delivery efficiency, and shear-thinning (thixotropic) process tolerance. Ordinary dimethicone (100/350cSt) has no crosslinked network, greasy, no thickening or sebum absorption; fumed silica thixotropic system poor transparency, dry-chalky; uncrosslinked silicone gel (pure polymer powder) hard to disperse, gritty. As sun care/color cosmetics/hair care demand "INCI compliant (D5 carrier), silky matte non-greasy, ambient processing no shear, shear-thinning not quality issue, 20kg PE/200kg iron drum, 2yr," sourcing a high-visc thixotropic, low-dose thickening, silky skin-feel, domestically mass-producible cosmetic-grade product has become the core gap for formulators.
Addressing this "silky thixotropy" pain point,
Anhui IOTA Silicone Oil Co., Ltd. (IOTA) officially launches
Silicone Elastomer Gel IOTA 9607 (INCI: Cyclopentasiloxane (and) Dimethicone Crosspolymer (and) Dimethicone/Vinyl Dimethicone Crosspolymer (and) Dimethiconol). Characterized by "colorless translucent gel, NV 14-17%, visc 250,000-450,000cP, 1-20% add, ambient process, silky slip non-greasy, enhance aesthetic, reduce tack, 20kg PE/200kg iron drum, non-haz, 2yr," and backed by "cyclosiloxane carrier + crosspolymer 3D network + dimethiconol interfacial compat," it serves as the "thickening skin-feel network" for skincare/haircare/color cosmetic/sun care/styling formulations.
Molecular Architecture: Cyclosiloxane Carrier + Crosslinked 3D Network + Dimethiconol Interfacial Compat 3D Logic
The core competitiveness of IOTA 9607 stems from its "D5 cyclic siloxane (volatile carrier) + crosslinked PDMS network (Dimethicone Crosspolymer + Dimethicone/Vinyl Dimethicone Crosspolymer) + Dimethiconol (hydroxy-terminated PDMS, interfacial compatibilizer)" precise composite architecture:
-
Crosspolymer 3D Network: PDMS crosspolymer and vinyl PDMS crosspolymer form nano-scale 3D elastic network trapping D5 — this is the "gel" essence, cannot truly dissolve in any oil phase, only stable dispersion. Network grants ultra-high viscosity (250-450k cP) and strong thixotropy (rest at high visc, shear-thin).
-
Cyclic D5 Volatile Carrier: Cyclopentasiloxane evaporates quickly after application, leaving elastomer network film — delivers "silky slip, non-greasy" skin feel, slight sebum absorption (mattifying/soft-focus).
-
Dimethiconol Interfacial Compat: Hydroxy-terminated PDMS acts as surfactant helping crosslinked network stably disperse in oil/silicone phase, preventing flocculation, while participating in film-forming for enhanced moisturizing feel.
Performance Leap: From "Pure Silicone Greasy" to "Cyclosiloxane-Carrier Silky Thixotropy"
Incorporating IOTA 9607 enables qualitative leaps:
-
Thickening & Suspension: Provides significant thickening in W/O, W/Si systems, suspending TiO₂/ZnO (sunscreen), pigments (color cosmetic), silicone elastomer microspheres, preventing settling.
-
Silky Skin-Feel: Replaces part of oils, network breaks on application releasing D5, leaves dry silky film after evaporation, eliminating "oil slick" and "tack" of traditional silicones, imparting "enhanced aesthetic."
-
Sebum Absorption / Matte: Porous crosslinked network adsorbs slight sebum, imparting mattifying effect to sunscreen/foundation, ideal for oily/combination skin.
-
Thixotropic Process Tolerance: High rest-viscosity ensures suspension stability, shear-thinning eases pumping/application/spreading — viscosity recovery on standing is normal thixotropic behavior, not a quality defect.
Application Penetration: From Sunscreen Film to Foundation Soft-Focus
IOTA 9607 covers sectors triple-sensitive to "silky skin-feel + thickening suspension + shear thixotropy":
-
Sun Care: Physical/chemical sunscreen, suspend TiO₂/ZnO, silky non-whitecast, water/sweat resistant, reduces formula tack.
-
Color Cosmetics: Foundation, BB cream, primer, providing slip spread, line-filling, matte soft-focus, long-wear.
-
Skincare: Cream, lotion, serum, reduce tack, enhance aesthetic (long-lasting moisturizing film),清爽 post-feel.
-
Hair & Styling: Hair gel, mousse, conditioner, dry non-tacky hold and silky touch, reduces static frizz.
IOTA Technical Guide: Oil-Phase Direct Disperse, ≤60℃ Closed, Avoid Acid/Base/Moisture
-
Dispersion: Directly disperse in formula oil phase (silicone or organic oil), no post high-shear needed; recommend pre-homogenizing oil phase before emulsification, or slowly pour dispersed oil phase into product with mild stirring; can also post-add if dispersion phase viscosity permits.
-
Temp Control: Heating in closed container, recommended ≤60℃ to avoid D5 volatilization loss.
-
Taboo Red Line: Moisture-proof, acid/base-proof, avoid prolonged high-temp open — D5 volatile (seal to prevent weight loss); strictly seal after each use; avoid direct strong acid/base (breaks network); viscosity recovery on standing is normal thixotropy, not quality issue.
-
Storage: 20kg PE/200kg iron drum; non-haz, moisture/acid/base-proof, sealed room temp, shelf 2yr; routine PPE, avoid eye.
Industry experts note that under cosmetics upgrading from "oily greasy" to "silky matte清爽" and sun/color demand for "high SPF non-whitecast, base makeup no cake" dual-cycle, silicone elastomer gels are upgrading from "import Dow/Shin-Etsu/Momentive DC9040/9041/9050 followers" to "visc 250-450k cP, NV 14-17%, D5 carrier, silky thixotropy" domestic reference network. IOTA 9607, with its "INCI cyclopentasiloxane+crosspolymer+dimethiconol+visc 250-450k cP+NV 14-17%+2yr" hard metrics,
fills the domestic supply chain gap for silicone elastomer gels in skincare/haircare/color/sun/styling fields, providing a mass-producible import-substitution path for downstream cosmetic formulators. This confirms domestic silicone elastomers are advancing steadily along "pure silicone oil (greasy) → fumed silica (chalky) → crosspolymer powder (hard disperse) → cyclosiloxane-carrier 9607 (silky thixotropic network)," with growing technical say in cosmetic key skin-feel materials.
