In personal care fields such as 2-in-1 shampoos and conditioners, the four-dimensional indicators of "internal phase composition — large particle spreading — surfactant compatibility — dry/wet combing" of silicone emulsions have always been the core contradiction restricting end-product hair care experience and consumer satisfaction. Traditional single dimethicone emulsions, while providing basic emollience, have low internal phase viscosity and thin films, resulting in short retention and difficult long-lasting softness. Ordinary amino silicones, while highly conditioning, are difficult to emulsify directly and have limited compatibility with anionic surfactants (e.g., shampoo main surfactants), prone to demulsification and oil floating. Some cationic polymers, while conditioning, lack the unique silky smooth feel and foam stability of silicones. With the continuous upgrading of comprehensive consumer demands for "2-in-1 efficient conditioning, silky gloss, easy combing, stable foam", finding a silicone emulsion with "high-viscosity dimethicone and amino silicone composite, large particle size, non-ionic O/W, solid content 57-63%" has become the core proposition for the refinement of domestic hair care silicones. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. officially launches IOTA 9504 (Aminopropyl Dimethicone (and) Dimethicone (and) Laureth-4 (and) Laureth-23) (INCI/CTFA Name as above). Characterized by "milky white viscous liquid; pH 5.5-7.5; centrifugal stability ≤0.5 ml (2500 rpm × 15 min); solid content 57-63% (120°C × 2 h); non-ionic O/W emulsion", backed by "high-viscosity dimethicone + amino silicone composite internal phase + large particle size + laureth emulsification", it serves as the "silk care choice" for hair care, achieving the leap from "single silicone short retention" to "amino silicone composite large-particle emulsion long-lasting conditioning". System Positioning: Non-Ionic O/W Composite Silicone Emulsion vs. Single Dimethicone Emulsion / Pure Amino Silicone IOTA 9504 belongs to the non-ionic oil-in-water (O/W) composite silicone emulsion system, distinct from single dimethicone emulsions and pure amino silicones. Single dimethicone emulsions have low internal phase viscosity, thin films, short retention. Pure amino silicones have poor compatibility with anionic surfactants after emulsification, prone to demulsification. 9504 innovatively composites high-viscosity dimethicone and amino silicone as the internal phase, combined with a laureth-4/laureth-23 non-ionic emulsification system — the composite internal phase balances emollience and amino conditioning, the large particle size enhances spreading coverage on hair, and the non-ionic nature ensures excellent compatibility with various surfactants (especially anionics), thoroughly solving the industry pain point of "difficult silicone emulsion-surfactant compatibility". Structural Architecture: High-Viscosity Dimethicone + Amino Silicone Composite Internal Phase + Large-Particle Non-Ionic O/W The core competitiveness of IOTA 9504 stems from the precision structural design of the composite silicone emulsion:

• High-Viscosity Dimethicone + Amino Silicone Composite Internal Phase: The internal phase is a composite system of high-viscosity dimethicone and amino silicone, combining the emollience and spreading of dimethicone with the adsorption and cross-linking of amino silicone; amino active groups form an elastic film on hair strands, providing long-lasting softness, silky smoothness and gloss.
• Large-Particle Silicone Emulsion: The large particle size allows silicone droplets to spread more uniformly on hair with larger coverage area, improving conditioning efficiency; meanwhile, large particles reduce penetration depth, avoiding flat roots and maintaining volume.
• Non-Ionic O/W Emulsion: Using laureth-4 and laureth-23 as non-ionic emulsifiers, the emulsion is near-neutral to weakly acidic (pH 5.5-7.5), with excellent compatibility with various surfactants in formulations, good foam stability, and easy to use.

Performance Leap: From "Short Retention Poor Compatibility" to "Long-Lasting Conditioning Stable Foam" Introducing IOTA 9504 brings a qualitative leap to hair care formulations:

• Excellent Compatibility: Good compatibility with various common cosmetic raw materials, especially compatible with anionic, non-ionic, and amphoteric surfactants, suitable for complex shampoo systems.
• 2-in-1 Efficient Conditioning: As an excellent conditioner for 2-in-1 shampoos, providing silky smoothness, gloss, and softness — cleansing and conditioning in one wash.
• Good Dry/Wet Combing: Provides excellent dry and wet combability, greatly reducing wet and dry combing resistance and reducing hair breakage.
• Moisturizing Breathable Hydrophobic Anti-Tack: Moisturizing, breathable, strongly hydrophobic, forming a water-resistant protective film on hair while preventing tackiness and greasiness.
• Foam Stability: Good foam stability without affecting the cleansing foam experience of shampoos.
• Easy to Use: Non-ionic O/W system, recommended to add in the late stage of formulation, addition temperature not exceeding 50°C, strong process compatibility.

Application Penetration: From 2-in-1 Shampoos to Conditioners The application boundary of IOTA 9504 covers all hair care scenarios requiring "conditioning + combing + foam stability":

• 2-in-1 Shampoos (Main Battlefield): Added at 0.5-5%, achieving both cleansing and conditioning in one wash, providing silky smoothness, gloss, and softness.
• Conditioners: Added at 1-10%, deep softening, improving dry/wet combability, restoring healthy hair shine.
• Hair Masks and Treatments: High solid content (57-63%) brings strong emollience, suitable for repairing severely damaged hair.
• Multi-Functional Wash Care: With good compatibility and foam stability, can be used in body washes and facial cleansers requiring mild conditioning.

Industry Insight: In hair care silicone emulsions, the structural design of IOTA 9504 — "high-viscosity dimethicone + amino silicone composite internal phase + large-particle non-ionic O/W" — is the key path to achieving the trinity of "long-lasting conditioning + dry/wet combing + foam stability" — the introduction of the composite internal phase solves the industry pain point of single dimethicone: "short retention", while the non-ionic large-particle system ends the application shortcoming of pure amino silicone: "poor compatibility with anionic surfactants, easy demulsification". IOTA 9504, with "INCI Aminopropyl Dimethicone (and) Dimethicone (and) Laureth-4 (and) Laureth-23 + pH 5.5-7.5 + centrifugal stability ≤0.5 ml + solid content 57-63%" hard metrics, fills the key supply chain link for domestic composite silicone emulsion in hair care (2-in-1 shampoos/conditioners/hair masks), providing a mass-producible silky conditioning high-performance silicone emulsion for downstream daily chemical enterprises. This confirms that domestic hair care silicones are leaping toward "single silicone emulsion → pure amino silicone → composite non-ionic large-particle emulsion" in terms of conditioning power and compatibility, with growing technical say in high-end hair care fields.
