In premium personal care and color cosmetics, how a sensory modifier "exists" on skin directly dictates luxury perception and wear time. Conventional linear silicones spread too fast and leave an oily film—causing face creams to float oil, foundations to migrate, and sunscreens to whiten upon sweat. Early silicone elastomer powders needed high-shear dispersion and risked pilling. As consumers demand "dry non-stuffy" creams, "velvet long-wear" foundations, and "sweat-resistant non-migrating" sunscreens, sourcing a translucent gel carried by cyclopentasiloxane (D5) with vinyl-crosslinked PDMS network, 15-25% non-volatile, 150-500k cP viscosity, has become the core challenge for domestic cosmetic elastomer substitution.
Addressing this "volatile carrier + network retention" pain point,
Anhui IOTA Silicone Oil Co., Ltd. (IOTA) officially launches
Silicone Resin Elastomer Gel IOTA 96004 (INCI: Cyclopentasiloxane (and) Dimethicone/Vinyl Dimethicone Crosspolymer). Characterized by "translucent paste, 15-25% non-volatile, 150000-500000 cP (25℃), 1-20% wide dosing," and backed by "D5 fast spread carrying elastomer net + slight sebum cache + velvet dry non-oily film," it serves as the "skin-feel anchor" for facial creams, long-wear foundations, sweat-proof sunscreens, and hair essences.
Molecular Architecture: D5 Carrier + Vinyl-Crosslinked Elastomer Biphasic Logic
The core competitiveness of IOTA 96004 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, trimethylsiloxysilicate nodes lending resinous rigidity. After D5 evaporates, the net collapses into a micron-thin, breathable, rebound-elastic silicone film that reads as "velvet press" not "wax tight".
-
Slight Sebum Absorption: Porous elastomer caches superficial sebum physically; immediate matte on oily skin without desiccating stratum corneum—safe for sensitive skin unlike strong oil-absorbing minerals.
Performance Leap: From "Linear Silicone Sheen" to "Elastomer Velvet Wear"
Incorporating IOTA 96004 enables qualitative leaps:
-
Skincare Cream Thickening-Silking: 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 velvet film; kills "oil-over-water" float in rich moisturizers.
-
Color Cosmetic Transfer-Resist: 3-8% in lip glaze lifts adhesion (no cup ring); 5-12% in foundation forms soft-focus elastomer net, pores blurred, sweat-wipe non-smear; eyeliner anti-smudge.
-
Sunscreen Sweat Film: Inorganic/chemical sunscreens compounded—D5 carries even spread, post-film resists water rinse and rub-migration; measured SPF decay drops 15-25%.
-
Hair Essence De-Weight: Replaces part of linear silicone oil in hair serum; no droopy oil, elastomer wraps cuticle for "dry shine" not "wet shine".
Application Penetration: From Sorbet Cream to Long-Wear Base
IOTA 96004 covers formulation sectors doubly sensitive to "feel + longevity":
-
Skincare: Refreshing moisturizer, oil-control lotion, primer, sleep mask.
-
Color: Liquid foundation/cushion, lip glaze, eyeliner pen, setting powder binder.
-
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.
Industry experts note that as the market shifts from "ingredient-watching" to "feel-watching," silicone elastomer gels have descended from imported prestige exclusives to standard modifiers in domestic creams and foundations. IOTA 96004, with "D5 + vinyl-crosslinked net" aligning with international first-line (Dow EL-5050, Shin-Etsu KSG-15 family) in INCI and viscosity band, not only localizes velvet dry-feel supply but also cuts formulator trial cost via its 1-20% wide window. This marks domestic cosmetic silicones' readiness to replace imports in the high-end sensory arena.
