In personal care fields such as 2-in-1 shampoos, conditioners, body washes, and skin care creams, the four-dimensional indicators of "internal phase viscosity — surfactant compatibility — silky skin feel — dry/wet combing" of silicone emulsions have always been the core contradiction restricting end-product wash care experience and consumer satisfaction. Traditional low-viscosity silicone emulsions, while providing basic lubrication, have insufficient internal phase molecular weight, forming thin films that are easily washed away, failing to achieve long-lasting softness. Ordinary cationic emulsions, while highly conditioning, have poor compatibility with anionic surfactants (main surfactants in shampoos), prone to oil floating and demulsification, affecting formulation stability. Some synthetic emulsions, while safe, lack the unique "fluffy silky feel" and foam stability of silicones. With the continuous upgrading of comprehensive consumer demands for "2-in-1 cleansing and care, silky gloss, easy combing, convenient application", finding an emulsified silicone with "high-viscosity dimethicone internal phase, laureth-3/9 emulsification, non-ionic O/W, solid content 50~57%" has become the core proposition for the refinement of domestic wash care silicones. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. officially launches IOTA 9505 Emulsified Silicone (INCI/CTFA Name: Dimethicone (and) Laureth-3 (and) Laureth-9). Characterized by "milky white liquid; solid content 50~57% (120°C × 2 h); pH 6.0~8.0; centrifugal stability ≤0.5 ml (2500 rpm × 15 min); non-ionic O/W emulsion", backed by "high-viscosity dimethicone internal phase + laureth non-ionic emulsification + fluffy silky conditioning", it serves as the "silky soft choice" for personal care, achieving the leap from "traditional silicone fake slip short retention" to "polyether emulsified silicone fluffy silky smooth". System Positioning: Non-Ionic O/W Polyether Emulsified Silicone vs. Traditional Cationic Silicone Emulsion IOTA 9505 belongs to the non-ionic oil-in-water (O/W) polyether emulsified silicone system, distinct from traditional cationic silicone emulsions. Traditional cationic emulsions rely on charge adsorption, easily neutralizing and demulsifying when encountering anionic surfactants, causing phase separation. IOTA 9505 innovatively adopts laureth-3 and laureth-9 as non-ionic emulsifiers, making the emulsion surface charge-free, with excellent compatibility with various surfactants (anionic, non-ionic, amphoteric), thoroughly solving the industry challenge of "silicone emulsion difficult to coexist with wash care surfactants". Molecular Architecture: High-Viscosity Dimethicone Internal Phase + Laureth Non-Ionic Emulsification + O/W Fluffy Silky The core competitiveness of IOTA 9505 stems from the precision structural design of polyether emulsified silicone:

• High-Viscosity Dimethicone Internal Phase: The internal phase is high-viscosity polyalkane (polydimethylsiloxane), with sufficient molecular weight, spreading on hair and skin to form a flexible protective film, providing long-lasting softness and silky smoothness and gloss, eliminating the "fake slip" that disappears after washing.
• Laureth Non-Ionic Emulsification: Laureth-3 and laureth-9 synergistically build a stable non-ionic emulsification layer, ensuring centrifugal stability ≤0.5 ml (2500 rpm × 15 min), no oil floating at high temperature, no stratification during long-term storage.
• O/W Fluffy Silky: The O/W system disperses silicone particles uniformly in the water phase, giving an instant silky feel upon contact; combined with moisturizing, breathability, good hydrophobicity, and anti-tack, providing a classic fluffy silky experience.

Performance Leap: From "Fake Slip Short Retention" to "Fluffy Silky Stable Foam" Introducing IOTA 9505 brings a qualitative leap to personal care formulations:

• Broad Compatibility: Good compatibility with various common cosmetic raw materials, seamlessly integrating into complex wash care systems without affecting stability.
• Excellent Conditioning: As an excellent conditioner for 2-in-1 shampoos, giving hair a silky smooth, glossy, soft feel — cleansing and conditioning in one.
• Excellent Dry/Wet Combing: Provides excellent dry and wet combability, greatly reducing combing resistance, reducing breakage and frizz.
• Moisturizing Breathable Anti-Tack: Moisturizing, breathable, strongly hydrophobic, forming a breathable waterproof film on hair/skin, anti-tack and non-greasy.
• Foam Stability: Good foam stability, ensuring dense and long-lasting cleansing foam for shampoos and body washes.
• Safe and Gentle: Safe, non-toxic, non-irritating, suitable for daily wash care and skin care creams.

Application Penetration: From 2-in-1 Shampoos to Skin Care Creams The application boundary of IOTA 9505 covers all personal care scenarios requiring "silky conditioning + surfactant compatibility + foam stability":

• 2-in-1 Shampoos (Main Battlefield): Added at 2~4%, achieving both cleansing and silky conditioning in one wash, with a fluffy silky feel.
• Hair Care Products: Added at 3~10%, deep softening, improving dry/wet combability, restoring healthy hair shine.
• Body Washes: Added at 2~4%, giving skin a silky feel after bathing, moisturizing and anti-tack.
• Skin Care Creams: Added at 3~10%, utilizing the non-ionic O/W system to improve cream spreadability and silky touch, breathable and non-comedogenic.

IOTA Technical Guide: Late-Stage Low-Temp Addition, Seal from Moisture

• Handling: Milky white liquid, pH 6.0~8.0 close to skin's weakly acidic environment; centrifugal stability ≤0.5 ml (2500 rpm × 15 min) indicates emulsion stability; solid content 50~57% (120°C × 2 h) convenient for dosing calculation; packaging: 50 Kg or 200 Kg plastic drum.

Industry Insight: In wash care silicone emulsions, the structural design of IOTA 9505 — "high-viscosity dimethicone internal phase + laureth non-ionic emulsification + O/W fluffy silky" — is the key path to achieving the trinity of "long-lasting silky + surfactant compatibility + foam stability" — the introduction of high-viscosity internal phase solves the industry pain point of traditional low-viscosity silicone: "fake slip short retention", while the non-ionic polyether emulsification system ends the application shortcoming of cationic silicone: "incompatible with anionic surfactants, easy demulsification". IOTA 9505, with "INCI Dimethicone (and) Laureth-3 (and) Laureth-9 + solid content 50~57% + pH 6.0~8.0 + centrifugal stability ≤0.5 ml" hard metrics, fills the key supply chain link for domestic polyether emulsified silicone in wash care (2-in-1 shampoo/hair care/body wash/skin cream), providing a mass-producible fluffy silky high-performance silicone emulsion for downstream daily chemical enterprises. This confirms that domestic wash care silicones are leaping toward "traditional silicone → cationic emulsion → non-ionic polyether emulsified silicone" in terms of silky feel and compatibility, with growing technical say in high-end personal care wash care fields.
