In the cosmetic silicone elastomer suspension spectrum, the dispersed phase of "PDMS/vinyl PDMS crosspolymer spherical microspheres (inner phase) + laureth-3/laureth-25 nonionic emulsifier stabilization (outer aqueous phase)" and "solids 62-68%, centrifugal stability <0.5ml (2500rpm×15min), pH 5.0-7.5, milky viscous liquid, hair 0.5-6%/skincare 10-20%/color 30-70% dosage gradient" jointly dictate suspension stability in O/W systems, silky-powdery feel delivery efficiency, and ambient medium-shear dispersion process boundary in water-based formulations. Pure oil-phase silicone gel (e.g., 9607) provides silky thixotropy but cannot directly enter aqueous phase; untreated silicone elastomer powder tends to settle/agglomerate in water, needing high-shear homogenization; traditional silicone oil emulsion (e.g., 350cSt dimethicone emulsion) has no crosslinked network, no powdery feel, no long-lasting silky. As skincare/suncare/color cosmetics/haircare demand "INCI compliant (nonionic O/W), direct aqueous addition, spherical microsphere powdery feel, medium-shear dispersion, 20kg/200kg PE drum, 12mo," sourcing a high-solids, centrifuge-stable, water-dispersible, domestically mass-producible cosmetic suspension has become the core gap for formulators. Addressing this "microsphere array" pain point, Anhui IOTA Silicone Oil Co., Ltd. (IOTA) officially launches Silicone Elastomer Suspension IOTA 9608 (INCI: Dimethicone/Vinyl Dimethicone Crosspolymer (and) Laureth-3 (and) Laureth-25). Characterized by "milky viscous liquid, solids 62-68%, centrifugal <0.5ml, pH 5.0-7.5, nonionic O/W, hair 0.5-6%/skincare 10-20%/color 30-70% add, 20kg/200kg PE drum, non-haz, 12mo," and backed by "spherical crosslinked microspheres + nonionic aqueous stabilization + medium-shear easy dispersion," it serves as the "silicone-elastomer microsphere array" for aqueous skincare/suncare/color/haircare formulations. Molecular Architecture: Spherical Crosslinked Microspheres + Nonionic Aqueous Stabilization + Medium-Shear Easy Disperse 3D Logic The core competitiveness of IOTA 9608 stems from its "inner phase: PDMS/vinyl PDMS crosspolymer nano spherical microspheres + outer phase: laureth-3/laureth-25 nonionic surfactant aqueous" precise O/W suspension architecture:

• Spherical Crosslinked Microspheres: Inner phase highly crosslinked PDMS/vinyl PDMS microspheres, spherical structure grants unique "silky slip and powdery feel" — microspheres roll on skin surface filling fine lines, delivering silica-like soft-focus but smoother and less cakey. Crosslinked network doesn't swell/dissolve, stably suspended as solid microspheres.
• Nonionic Aqueous Stabilization: Laureth-3 and laureth-25 as nonionic emulsifiers/stabilizers form steric hindrance + mild electrostatic repulsion dual-stability, centrifugal 2500rpm×15min separation <0.5ml, thickens on standing but recovers with moderate stirring (thixotropic), pH 5.0-7.5 gentle for most cosmetic systems.
• Medium-Shear Easy Disperse: Unlike pure elastomer powder needing high-shear homogenization, 9608 pre-dispersed in aqueous phase, formulators only need medium shear to uniformly blend into water phase — can add directly to water phase or post-add, drastically lowering production barrier.

Performance Leap: From "Pure Powder High-Shear" to "Pre-Suspended Medium-Shear Disperse" Incorporating IOTA 9608 enables qualitative leaps:

• Aqueous Formulation Silky Upgrade: Direct addition to water phase, enabling water-based formulations (e.g., water-based sunscreen, water-based foundation, light lotion) that cannot use oil-phase silicone gel to also obtain silicone-elastomer powdery feel and long-lasting silky slip.
• Reduce Formula Tack: Replaces part of thickeners or high-visc oils, reducing tack, making product more slip and non-sticky.
• Color Cosmetic Soft-Focus Long-Wear: At 30-70% high dosage, abundant spherical microspheres fill skin texture, paired with volatile cyclosiloxane and low-visc silicone for enhanced effect, long-wear no-transfer.
• Haircare Light & Bouncy: 0.5-6% low addition imparts silky and powdery feel to shampoo/conditioner, no weighing hair down, post-wash bouncy not flat.

Application Penetration: From Water-Based Sunscreen to Foundation Soft-Focus IOTA 9608 covers sectors triple-sensitive to "aqueous formulation + silicone-elastomer microsphere powdery feel + medium-shear easy disperse":

• Skincare & Sun Care: Water-based sunscreen lotion, light emulsion, gel cream, 10-20% add, silky non-whitecast, reduces tack.
• Color Cosmetics: Foundation, BB cream, primer, concealer, 30-70% add, pore/line filling, matte soft-focus, long-wear.
• Haircare: Shampoo, conditioner, hair mask, 0.5-6% add, silky non-greasy, increases hair volume.
• Other Personal Care: Body lotion, hand cream, etc., enhancing application silky and powdery feel.

IOTA Technical Guide: Water-Phase Direct Add, Medium Shear, Pair with Volatile Cyclosiloxane

• Dispersion: Can add to water phase; if uniform dispersion ensured, can also post-add; recommend medium shear mixing.
• Pairing: For best silky-powdery feel, recommend pairing with volatile cyclodimethicone and low-visc silicone oil/other oils in formula, minimizing or avoiding high-visc oils.
• Taboo Red Line: Moisture-proof, sun/rain-proof, avoid over-high shear — thickening on standing is normal, moderate stir recovers; avoid strong acid/base (pH outside 5.0-7.5 may break emulsion); nonionic system, avoid excessive cationic polymer co-use (may flocculate).
• Storage: 20kg/200kg PE drum; non-haz, moisture/sun/rain-proof, strictly sealed after each use, shelf 12mo; routine PPE, avoid eye.
