In the two intersecting fields of personal care (skin care, color cosmetics, cleansing & hair care) and agrochemicals (pesticide tank-mixing, foliar spraying), the four-dimensional indicators of "spreading & diffusion — dissolution & solubilization — low surface tension — non-residue" of oil-phase ingredients have always been the core contradiction restricting end-product efficacy. Traditional silicones, while providing a smooth feel, have limited compatibility with other hydrocarbon oils, making it difficult to act as an "oil-soluble spreading agent" to significantly expand oil-phase coverage. Ordinary hydrocarbon additives, while low-cost, have high viscosity and slow diffusion, tending to leave a sticky, greasy feel on skin or leaves. Some synthetic esters, though light, lack the unique low surface tension and strong cleansing function of silicones. With the dual demands of "synergism and dosage reduction" in agrochemicals and "non-greasy, high-gloss, color-fast" in personal care, finding an oil-soluble spreading agent with "alkyl-modified trisiloxane, viscosity 2.5-3.5 mm²/s, specific gravity 0.830-0.850, refractive index 1.41-1.42, flash point 110°C" has become the core proposition for the cross-field refinement of domestic modified silicones.
Addressing this,
Anhui IOTA Silicone Oil Co., Ltd. officially launches
IOTA 210 Modified Silicone for Personal Care (alkyl-modified trisiloxane). Characterized by "colorless transparent liquid; viscosity 2.5-3.5 mm²/s (25°C); specific gravity 0.830-0.850 (25°C); refractive index 1.41-1.42 (25°C); flash point 110°C; insoluble in water, compatible with most organic oils such as ethanol and toluene", backed by "alkyl-modified low surface tension + trisiloxane low viscosity + oil-soluble spreading & solubilization", it serves as the "spread-reach choice" for personal care and agrochemicals,
achieving the leap from "traditional silicone limited spreading" to "alkyl-modified trisiloxane strong spreading oil-soluble expansion".
System Positioning: Alkyl-Modified Trisiloxane vs. Traditional Dimethicone / Ordinary Hydrocarbon Additives
IOTA 210 belongs to the alkyl-modified trisiloxane system, distinct from traditional dimethicone and ordinary hydrocarbon additives. Traditional dimethicone is a symmetric linear molecule with a narrow compatibility window with hydrocarbon oils, insufficient spreading and solubilizing capacity. Ordinary mineral oil and vegetable oil have high viscosity and slow diffusion, easily leaving sticky residue on skin or leaves. Alkyl-modified trisiloxane innovatively introduces alkyl side chains onto the trisiloxane backbone — the alkyl group grants natural affinity with hydrocarbon and vegetable oils, making it a "good solubilizer" for silicone and hydrocarbon oils; the trisiloxane backbone maintains ultra-low viscosity and low surface tension, bringing excellent spreadability and diffusion, thoroughly solving the industry challenge of "oil phase won't spread, won't dissolve".
Molecular Architecture: Alkyl-Modified Low Surface Tension + Trisiloxane Low Viscosity + Oil-Soluble Spreading
The core competitiveness of IOTA 210 stems from the precision molecular design of alkyl-modified trisiloxane:
-
Alkyl-Modified Low Surface Tension: The alkyl side chain synergizes with the siloxane backbone to give extremely low surface tension, excellent spreadability and diffusion, promoting skin absorption of personal care products and increasing leaf utilization of pesticides.
-
Trisiloxane Low Viscosity: The trisiloxane backbone lowers viscosity to 2.5-3.5 mm²/s (25°C), with excellent fluidity, rapidly spreading into an ultra-thin uniform film on skin or leaf surfaces, reducing dryness and providing a smooth touch.
-
Oil-Soluble Spreading & Solubilization: Insoluble in water but compatible with most organic oils such as ethanol and toluene, acting as an oil-soluble spreading agent and solubilizer to expand oil-phase coverage; non-residue avoids stickiness and greasiness.
Performance Leap: From "Limited Spreading" to "Strong Spreading Oil-Soluble Expansion"
Introducing IOTA 210 brings a qualitative leap to personal care and agrochemical formulations:
-
Oil-Soluble Spreading Agent: Good spreadability, as an oil-soluble spreading agent, significantly expanding oil-phase coverage on skin or leaf surfaces.
-
Low Viscosity Low Surface Tension: Viscosity 2.5-3.5 mm²/s, extremely low surface tension, rapid diffusion, promoting absorption and utilization of active ingredients.
-
Strong Solubilization: Good solubilizer for silicone and hydrocarbon oils, improving formulation compatibility and stability.
-
Smooth Non-Residue: Good smooth feel, reducing dryness, strong cleansing function, no sticky greasy residue after use.
-
Enhanced Lipstick Performance: Enhances lipstick gloss and color fastness, reducing stickiness and greasiness.
-
Enhanced Vegetable Oil Spreading: Improves spreadability of vegetable oils, reducing stickiness and greasiness while promoting skin absorption.
Application Penetration: From Personal Care to Agrochemical Spraying
The application boundary of IOTA 210 spans both personal care and agrochemical fields:
-
Personal Care (Main Battlefield): Used in skin care (moisturizers, styling hairspray, makeup removers, facial cleansers, sunscreens), color cosmetics (lipstick, eyeshadow), and hair care products; specific addition amount determined by formulation trials.
-
Color Cosmetics Enhancement: Enhances lipstick gloss and color fastness, reducing stickiness and greasiness.
-
Agrochemical Formulations: Added at 3-10% based on formulation; 0.03%-0.1% for tank-mix spraying; adding 5% oil-soluble adjuvant or mineral oil or methyl oleate further expands coverage.
-
Foliar Spreading: As an oil-phase spreading agent, enhances oil-phase spreading performance, giving pesticides better coverage and improving utilization.

Industry Insight: In cross-field applications of modified silicones, the molecular design of alkyl-modified trisiloxane — "alkyl-modified low surface tension + trisiloxane low viscosity + oil-soluble spreading" — is the key path to achieving the trinity of "strong spreading + high solubilization + non-residue" —
the introduction of alkyl solves the industry pain point of traditional dimethicone: "poor compatibility with hydrocarbon oils, insufficient spreading", while the trisiloxane backbone ends the application shortcoming of ordinary hydrocarbon additives: "high viscosity, slow diffusion, easy stickiness". IOTA 210, with "alkyl-modified trisiloxane + viscosity 2.5-3.5 mm²/s + specific gravity 0.830-0.850 + refractive index 1.41-1.42 + flash point 110°C" hard metrics,
simultaneously fills the key supply chain links for domestic modified silicone in both personal care (skin care/color cosmetics/hair care) and agrochemicals (formulation/tank-mix spraying), providing a mass-producible strong-spreading high-performance spreading agent for downstream daily chemical and agrochemical enterprises. This confirms that domestic modified silicones are leaping toward "dimethicone → hydrocarbon additives → alkyl-modified trisiloxane" in terms of spreading power and solubilization, demonstrating unique technical value in cross-field applications.
