In premium skincare and color cosmetics, how a sensory modifier "exists" on skin directly dictates application texture and visual blurring power. Conventional linear silicones spread too fast and leave an oily film—causing face creams to float oil, sunscreens to feel stuffy. Traditional silicone elastomer powders needed high-shear dispersion and risked pilling, limiting use in anhydrous and sensitive-skin formulas. As consumers demand "dry-silky, quick-absorbing, pore-blurring" effects, sourcing a translucent gel carried by cyclopentasiloxane (D5) with vinyl-crosslinked PDMS network, 14-18% non-volatile, 250-500k cP viscosity, has become the core gap for domestic silicone elastomer segmentation.
Addressing this "volatile carrier + network retention" pain point,
Anhui IOTA Silicone Oil Co., Ltd. (IOTA) officially launches
Silicone Elastomer Gel IOTA 96451 (INCI: Cyclopentasiloxane (and) Dimethicone/Vinyl Dimethicone Crosspolymer). Characterized by "colorless to translucent gel, 14-18% non-volatile, 250000-500000 cP (25℃), 1-20% wide dosing," and backed by "D5 fast spread carrying elastomer net + dry-touch tack-reduction + slight sebum cache," it serves as the "dry-touch anchor" for oil-control creams, pore-blurring primers, water-resistant sunscreens, and leave-in hair serums.
Molecular Architecture: D5 Carrier + Vinyl-Crosslinked Elastomer Biphasic Logic
The core competitiveness of IOTA 96451 stems from its sol-gel topology of "volatile cyclo-siloxane carrier + non-volatile crosslinked elastomer particles":
-
D5 Carrier Fast Spread: Cyclopentasiloxane (D5) as continuous phase—low surface tension (~17 mN/m), high spread coefficient—flash-liquefies on skin carrying the elastomer network evenly over dermatoglyphics; D5 flashes off in minutes, leaving zero oily residue.
-
Vinyl-Crosslinked Retention Net: Dispersed phase is Dimethicone/Vinyl Dimethicone Crosspolymer—vinyl groups participate in hydrosilylation forming 3D network. After D5 evaporates, the net collapses into a micron-thin, breathable, rebound-elastic silicone film that reads as "dry-silky powdery feel" not "waxy tight film".
-
Slight Sebum Absorption: Porous elastomer caches superficial sebum physically; immediate matte on oily skin without desiccating stratum corneum—safe for sensitive skin.
Performance Leap: From "Linear Silicone Sheen" to "Elastomer Dry-Touch"
Incorporating IOTA 96451 enables qualitative leaps:
-
Skincare Oil-Control: Non-emulsifying thickener in W/O or W/Si systems; 1-5% pushes cream to "sorbet texture", elastomer breaks on rub releasing D5 water-feel, leaves dry film; kills "oil-over-water float" and "tacky non-absorb" in rich moisturizers.
-
Color Cosmetic Blurring: 5-15% in primer, D5 carries network to fill fine lines and pores, creating smooth canvas for foundation; post-film resists water rinse and rub-friction, extending wear.
-
Sunscreen Spread & Durability: Inorganic/chemical sunscreens compounded—lifts spreadability, film forms even, reduces "whitening" and "pilling"; post-D5 evaporation, elastomer net boosts water/sweat resistance.
-
Hair Essence De-Tack: Replaces part of linear silicone oil in hair serum; no droopy oil, elastomer wraps cuticle for "dry shine" not "wet shine", improving combability.
Application Penetration: From Oil-Control Cream to Pore-Blurring Primer
IOTA 96451 covers formulation sectors doubly sensitive to "dry-touch + blurring":
-
Skincare: Refreshing moisturizer, oil-control lotion, primer, pore minimizer, sleep mask.
-
Color: Liquid foundation/cushion, concealer, setting products, lip products (reduce tack).
-
Sun Care: Chemical sunscreen milk, physical sunscreen stick, kids water-resistant SPF.
-
Hair: Leave-in essence, volumizing shampoo elastomer modifier.
IOTA Technical Guide: Cold Mix First, Seal Against Flash
-
Dispersion: Stir directly into oil phase (silicone/ester/hydrocarbon), room-temp slow agitation suffices—no homogenizer needed; in emulsions, homogenize oil phase 60-70℃ then cool below 40℃ before blending, or post-add into viscous emulsion.
-
Viscosity Cut: Pre-blend 1:1~1:3 with dimethicone (100-350 cSt), D5, phenyl silicone, or esters if original paste too stiff.
-
Heat Red Line: If heating mandatory, sealed vessel and ≤60℃ to prevent D5 loss and lumping; never open-kettle boil.
-
Storage Recovery: Surface crust or center lump after long rest is normal (micro D5 loss); light stir or sealed warm-back restores; no performance loss.
-
Safe Storage: 18kg plastic / 200kg iron drum, non-haz; moisture-proof, no acid/alkali, reseal strictly; 24 months at room temp sealed; storage temp ≤60℃.
Industry experts note that as the market shifts from "ingredient-watching" to "feel-watching," silicone elastomer gels are descending from imported prestige exclusives to standard modifiers in domestic creams and foundations. IOTA 96451, with "D5 + vinyl-crosslinked net" aligning with international first-line (Dow EL-8051, Shin-Etsu KSG-18 family) in INCI and viscosity band,
fills the domestic mass-production gap for dry-touch silicone elastomers in the oil-control and pore-blurring track, giving downstream firms a practical path to shorten high-end sensory raw-material procurement radius. This confirms domestic cosmetic silicones are advancing steadily along "block design → scenario validation → scale supply," with rising say in oil-control and fine-line-blurring technologies.
