In personal care fields such as skin care, sun care, color cosmetics, deodorants, antiperspirants, and hair conditioning, the four-dimensional indicators of "volatility — sensorial lightness — physiological inertness — formulation compatibility" of carrier oils and silicones have always been the core contradiction restricting end-product experience and consumer satisfaction. Traditional cyclic silicones (e.g., D6), while offering good volatility, face increasing regulatory pressure regarding environmental and safety concerns. Ordinary dimethicone, while relatively inert, has high molecular weight and low volatility, leaving a greasy after-feel. Some synthetic oils, though dry, have limited compatibility with organic UV filters, pigments, and actives, making them difficult to use as multifunctional carriers. With the Clean Beauty trend and continuous upgrading of comprehensive demands for "dry, non-greasy, highly compatible, non-irritating" products, sourcing a caprylyl trimethicone with "low molecular weight, specific gravity 0.830-0.850, viscosity 2-5 cSt" has become the core proposition for domestic personal care silicone autonomy. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. officially launches IOTA 9942 Caprylyl Trimethicone (INCI/CTFA Name: Caprylyl Trimethicone). Characterized by "colorless transparent liquid; specific gravity 0.830-0.850 (25°C); viscosity 2-5 cSt (25°C); refractive index 1.41-1.43 (25°C); physiological inertness; excellent solvent compatibility; excellent volatility", backed by "capryl low surface energy + trimethicone inert backbone + low molecular weight controlled volatility", it serves as the "fresh choice" for personal care, achieving the leap from "traditional silicone greasy residue" to "caprylyl trimethicone dry conditioning". System Positioning: Caprylyl Trimethicone vs. Traditional Cyclic Silicone / Ordinary Dimethicone IOTA 9942 belongs to the caprylyl trimethicone system, distinct from traditional cyclic silicones and ordinary dimethicone. Cyclic silicones (D6) volatilize quickly but face regulatory challenges. Ordinary dimethicone has high viscosity, does not volatilize, and easily forms an oily film causing stickiness. Caprylyl trimethicone innovatively introduces capryl side chains into a trimethicone backbone — the capryl group lowers surface tension, providing excellent spreadability and dry feel; low molecular weight ensures excellent volatility with no residue; the trimethicone backbone provides physiological inertness and high safety, thoroughly avoiding the application shortcomings of traditional silicones. Molecular Architecture: Capryl Low Surface Energy + Trimethicone Inert Backbone + Low MW Controlled Volatility The core competitiveness of IOTA 9942 stems from the precision molecular design of caprylyl trimethicone:

• Capryl Low Surface Energy: Capryl side chains grant extremely low surface tension, enabling easy spreading on skin and hair, forming a uniform ultra-thin film. The hydrophobic nature of capryl brings a silky touch, eliminating greasiness and giving skin and hair a "dry and fresh" experience.
• Trimethicone Inert Backbone: The main chain is trimethicone, highly physiologically inert, non-irritating to skin and hair. Refractive index 1.41-1.43 provides optical transparency, not affecting formulation appearance, suitable for colorless skin care and makeup products.
• Low MW Controlled Volatility: Low molecular weight organosiloxane structure with viscosity only 2-5 cSt, excellent volatility, rapidly volatilizing after application without sticky residue; ensuring sufficient time for actives penetration while presenting a dry feel in a short time.

Performance Leap: From "Greasy Residue" to "Dry Conditioning Non-Irritating" Introducing IOTA 9942 brings a qualitative leap to personal care formulations:

• Excellent Conditioning: Strong conditioning effect on skin and hair, improving hair combability and reducing frizz; forms a breathable protective film on skin, softening and moisturizing.
• Dry Non-Greasy Feel: Excellent volatility, quickly dry after use, no oily film residue, fresh and comfortable consumer experience.
• Physiologically Inert, Non-Irritating: Highly inert, no irritation to skin and hair, suitable for sensitive skin formulas and children's care products.
• Excellent Solvent Compatibility: Miscible with various organic solvents, serving as an ideal carrier and solvent, compatible with organic UV filters, pigments, essential oils, improving formulation stability and efficacy.
• Low Density Light Texture: Specific gravity 0.830-0.850, giving formulations a light texture, avoiding the heaviness of traditional oils.
• Low Viscosity Easy Processing: Viscosity 2-5 cSt (25°C), excellent fluidity, convenient for mixing, emulsification, and filling.

Application Penetration: From Skin Care to Hair Conditioning The application boundary of IOTA 9942 covers all personal care scenarios requiring "dry feel + conditioning + carrier":

• Skin Care & Sun Care (Main Battlefield): As carrier oil, improving spreadability of creams and lotions; in sunscreens, helping disperse organic UV filters, enhancing SPF while eliminating white cast, providing dry touch.
• Color Cosmetics: Used in foundations, lipsticks, eyeshadows, improving pigment dispersion, providing silky application and long-lasting wear; low refractive index reduces oily appearance.
• Deodorants & Antiperspirants: As actives carrier, quickly volatilizing to leave a dry film, reducing sticky discomfort.
• Hair Conditioning: Used in shampoos, conditioners, hair masks, improving wet and dry combability, reducing frizz, imparting natural shine and soft touch to hair.
• Emulsion Carrier: Can be used in water-based systems via emulsification, expanding to more aqueous personal care formulations.

Industry Insight: In personal care silicones, the molecular design of caprylyl trimethicone — "capryl low surface energy + trimethicone inert backbone + low MW controlled volatility" — is the key path to achieving the trinity of "dry feel + excellent conditioning + high safety" — the introduction of capryl solves the industry pain point of traditional dimethicone: "greasy residue", while the low molecular weight volatility ends the application shortcoming of cyclic silicones: "regulatory pressure". IOTA 9942, with "INCI Caprylyl Trimethicone + viscosity 2-5 cSt + specific gravity 0.830-0.850 + refractive index 1.41-1.43 + physiological inertness" hard metrics, fills the key supply chain link for domestic caprylyl trimethicone in personal care (skin care/sun care/color cosmetics/deodorants/hair conditioning), providing a mass-producible eco-friendly high-performance silicone oil for downstream daily chemical enterprises. This confirms that domestic personal care silicones are leaping toward "cyclic silicone → ordinary dimethicone → caprylyl trimethicone" in terms of sensorial experience and safety, with growing technical say in high-end personal care fields.
