In the cosmetic silicone elastomer gel spectrum, the network structure of "cyclopentasiloxane (D5) carrier + PDMS/vinyl PDMS crosspolymer 3D skeleton" and "NV 12.00-12.75%, visc 200,000-500,000cP (25℃), penetration 300-400 (1/10mm), colorless to slightly yellow transparent to translucent paste, 20kg PE/200kg iron drum, 1yr" jointly dictate thickening boundary in W/O, W/Si systems, dry-silky skin-feel delivery efficiency, and paste firmness process tolerance. Ordinary dimethicone (100-350cSt) has no crosslinked network, greasy, no thickening or sebum absorption; fumed silica thixotropic system poor transparency, dry-chalky. While IOTA 9607 (NV 14-17%, no penetration index) is also a D5-carrier elastomer gel, 9600D differentiates with more precise paste hardness control (penetration 300-400) and slightly lower solids (12-12.75%), positioning as "softer, easier to blend with dimethicone/cyclics/phenyl esters/hydrocarbons for visc reduction." As sun/color/haircare demand "INCI compliant (D5 carrier), silky dry non-greasy, ambient process no shear, controlled penetration, blendable with multiple oil phases, 1yr," sourcing a high-visc paste, defined penetration, blendable, domestically mass-producible cosmetic-grade product has become the core gap for formulators.
Addressing this "silky paste base" pain point,
Anhui IOTA Silicone Oil Co., Ltd. (IOTA) officially launches
Silicone Elastomer Gel IOTA 9600D (INCI: Cyclopentasiloxane (and) Dimethicone/Vinyl Dimethicone Crosspolymer). Characterized by "colorless to slightly yellow transparent to translucent paste, NV 12.00-12.75%, penetration 300-400, visc 200,000-500,000cP, ambient process, silky slip dry non-greasy, reduces tack, enhances cyclic silicone aesthetic, 20kg PE/200kg iron drum, non-haz, 1yr," and backed by "cyclosiloxane carrier + crosspolymer 3D network + controlled-penetration paste base," it serves as the "silky paste base" for skincare/haircare/color cosmetic/sun care/styling oil-phase formulations.
Molecular Architecture: Cyclosiloxane Carrier + Crosslinked 3D Network + Controlled-Penetration Paste Base 3D Logic
The core competitiveness of IOTA 9600D stems from its "D5 cyclic siloxane (volatile carrier) + PDMS/vinyl PDMS crosspolymer (3D elastic network) + high-Mw silicone blend matrix" precise composite architecture:
-
Crosspolymer 3D Network: PDMS/vinyl PDMS crosspolymer forms nano-scale 3D elastic network trapping D5 — the "gel" essence, cannot truly dissolve, only stable dispersion. Network grants ultra-high viscosity (200-500k cP) and paste form.
-
Cyclic D5 Volatile Carrier: Cyclopentasiloxane evaporates quickly after application, leaving elastomer network film — delivers "silky comfortable slip, dry non-greasy" skin feel, slight sebum absorption (mattifying/soft-focus). NV only 12.00-12.75% means ~87% D5, leaving an ultra-thin silicone film post-evaporation, lighter skin feel.
-
Controlled-Penetration Paste Base: Penetration 300-400 (1/10mm) places the paste in "soft ointment-semi-solid" range — softer and more spreadable than 9607, and can be blended with dimethicone, cyclics, phenyl silicones, fatty esters, hydrocarbons to actively reduce viscosity, flexibly adapting from cream to lotion formats.
Performance Leap: From "Pure Silicone Greasy" to "Cyclosiloxane Silky Paste Base"
Incorporating IOTA 9600D enables qualitative leaps:
-
Thickening & Suspension: Provides significant thickening in W/O, W/Si systems, suspending TiO₂/ZnO (sunscreen), pigments (color cosmetic), preventing settling.
-
Silky Dry Skin-Feel: Replaces part of oils, network releases D5 on application, leaves dry silky film after evaporation, eliminating "oil slick" and "tack."
-
Sebum Absorption / Matte: Porous crosslinked network adsorbs slight sebum, imparting mattifying effect to sunscreen/foundation.
-
Blendable Viscosity Reduction: Can blend with dimethicone, cyclics, phenyl silicones, fatty esters, hydrocarbons to lower viscosity — convenient for formulators to tune target format.
-
Vs 9607: 9607 NV 14-17%, no penetration spec, silky thixotropic network; 9600D NV 12-12.75%, penetration 300-400, softer and more blendable — together they form a "9607 high-solids thixotropic network / 9600D low-solids soft paste base" complementary pair.
Application Penetration: From Sunscreen Film to Styling Products
IOTA 9600D covers sectors triple-sensitive to "silky dry + thickening suspension + blendable flexibility":
-
Sun Care: Physical/chemical sunscreen, suspend TiO₂/ZnO, silky non-whitecast, water/sweat resistant, reduces tack.
-
Color Cosmetics: Foundation, BB cream, primer, silky spread, line-filling, matte soft-focus.
-
Skincare: Cream, lotion, serum, reduces tack, enhances cyclic silicone aesthetic benefit.
-
Hair & Styling: Hair gel, mousse, conditioner, dry non-tacky hold and silky touch.
IOTA Technical Guide: Oil-Phase Direct Disperse, ≤60℃ Closed, Blendable for Viscosity Cut
-
Dispersion: Directly disperse in formula oil phase (silicone or organic oil), stir uniform, no post high-shear needed; recommend pre-homogenizing oil phase or slowly pour dispersed oil into product with mild stir; can post-add if dispersion phase viscosity permits.
-
Blend to Cut Visc: For ease of use, can blend with dimethicone, cyclics, phenyl silicones, fatty esters, hydrocarbons to reduce viscosity.
-
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).
-
Storage: 20kg PE/200kg iron drum; non-haz, moisture/acid/base-proof, sealed room temp, shelf 1yr; routine PPE, avoid eye.
Industry Expert Insight:
Industry experts note that under cosmetics upgrading from "oily greasy" to "silky dry" and sun/color cosmetics demanding "high SPF non-whitecast, base makeup no cake" dual-cycle, low-solids, controlled-penetration silicone elastomer gels are upgrading from "imported Dow/Shin-Etsu/Momentive DC9040/9045 series followers" to "visc 200,000-500,000cP, penetration 300-400, NV 12.00-12.75%, D5 carrier, silky paste base" domestic reference product. IOTA 9600D, with its "INCI Cyclopentasiloxane + Crosspolymer + Penetration 300-400 + 1yr" hard metrics,
fills the domestic supply chain gap for low-solids controlled-penetration silicone elastomer gels in skincare/haircare/color cosmetic/sun care fields, providing a mass-producible import-substitution solution for downstream formulators. This confirms domestic silicone elastomers are advancing steadily along "pure silicone oil (greasy) → 9607 high-solids network (thixotropic) → 9600D low-solids paste base (controlled softness)", with growing technical say in cosmetic key skin-feel materials.
