In personal care fields such as color cosmetics, sun care, face and body products, antiperspirants & deodorants, and cuticle care, the multi-phase compatibility of "silicone-polyether-pigment-UV filter-lip keratin" has always been the core contradiction restricting product stability and consumer experience. Traditional polydimethylsiloxane, while spreadable, lacks polarity and has limited compatibility with organic UV filters and pigments, making it difficult to stably suspend powders in high-SPF sunscreens and heavy makeup formulas. Ordinary polyether-modified silicones, while improved in hydrophilicity, tend to feel sticky and lack sufficient affinity and moisturization for lip keratin, failing to balance the triple demands of "powder suspension + moisturization + gloss." With the continuous upgrading of comprehensive consumer demands for long-lasting makeup, high-SPF non-whitening sunscreen, and high-gloss lip care, finding a polyether-modified polydimethylsiloxane with "alkoxy ether functional groups, viscosity 40-60 mm²/s, refractive index 1.42, combining wetting, moisturization, and powder dispersion" has become the core proposition for the refinement of domestic personal care silicones.
Addressing this,
Anhui IOTA Silicone Oil Co., Ltd. officially launches
IOTA 25562 Personal Care Alkoxy Ether Silicone (INCI Name: Bis-Hydroxyethoxypropyl Dimethicone). Characterized by "colorless to pale yellow, transparent to slightly hazy liquid; viscosity 40-60 mm²/s (25°C); refractive index 1.42 (25°C); polyether-modified polydimethylsiloxane with alkoxy ether functional groups", backed by "alkoxy ether polar affinity + polyether chain wetting + polysiloxane backbone spreading", it serves as the "radiance choice" for personal care,
achieving the leap from "traditional silicone multi-phase incompatibility" to "alkoxy ether silicone full compatibility and powder suspension".
System Positioning: Alkoxy Ether Modified Polydimethylsiloxane vs. Traditional Dimethicone / Ordinary Polyether Silicone
IOTA 25562 belongs to the alkoxy ether functional group-bearing polyether-modified polydimethylsiloxane system, distinct from traditional dimethicone and ordinary polyether silicones. Traditional dimethicone is non-polar, with poor compatibility with organic UV filters and pigments, prone to powder floating and whitening. Ordinary polyether silicones introduce polyether segments to improve hydrophilicity, but improper ether chain ratio leads to sticky skin feel and insufficient lip affinity. Alkoxy ether silicone innovatively introduces bis-hydroxyethoxypropyl groups onto the polysiloxane backbone — the alkoxy ether functional groups grant excellent skin affinity and wetting, the polyether chain provides moisturization and fragrance retention, and the polydimethylsiloxane main chain maintains low surface tension and spreadability, thoroughly solving compatibility shortcomings in multi-phase formulations.
Molecular Architecture: Alkoxy Ether Polar Affinity + Polyether Chain Wetting + Polysiloxane Backbone Spreading
The core competitiveness of IOTA 25562 stems from the precision molecular design of bis-hydroxyethoxypropyl dimethicone:
-
Alkoxy Ether Polar Affinity: Bis-hydroxyethoxypropyl functional groups introduce polar hydroxyl and ether oxygen bonds, giving the molecule excellent affinity to skin stratum corneum and lip mucosa, providing deep moisturization and gloss; meanwhile, alkoxy ether groups form hydrogen bonds with organic UV filters and fragrance molecules, achieving excellent moisturizing and fragrance retention.
-
Polyether Chain Wetting: Polyether-modified segments lower surface tension, granting excellent wetting performance and easy spreadability on skin; wetting and encapsulating pigment surfaces to prevent powder agglomeration and improve dispersion stability.
-
Polysiloxane Backbone Spreading: The polydimethylsiloxane main chain provides low surface energy and high spreadability, forming a uniform breathable film on skin and hair; refractive index 1.42 gives suitable optical properties without affecting formulation transparency, suitable for colorless to pale yellow systems.
Performance Leap: From "Multi-Phase Incompatibility" to "Full Compatibility, Powder Suspension & Gloss"
Introducing IOTA 25562 brings a qualitative leap to personal care formulations:
-
Excellent Skin Affinity: Alkoxy ether functional groups highly compatible with skin stratum corneum, providing a soft touch and reducing formulation irritation.
-
Unique Compatibility: Achieves full compatibility in multi-phase systems of silicone-polyether-pigment-UV filter, avoiding phase separation and powder floating.
-
Superior Wetting & Moisturizing: Polyether chains absorb environmental moisture for long-lasting hydration; alkoxy ether groups lock fragrance molecules for extended scent retention.
-
Excellent Powder Dispersion & Suspension: Outstanding dispersion and suspension of pigments; as a suspending aid in powder formulations, significantly improves storage stability and anti-settling performance of color cosmetics.
-
SPF Enhancement: In sun care formulations, uniformly disperses organic UV filters, reduces filter agglomeration, improves UV blocking efficiency, thereby enhancing SPF value.
-
Lip Affinity & Moisturization: Excellent affinity to lip mucosa, providing deep moisturization and plumping effect, imparting natural gloss to lips.
-
Moderate Viscosity for Easy Processing: Viscosity 40-60 mm²/s (25°C), good fluidity, convenient for formulation mixing and emulsification.
Application Penetration: From Color Cosmetics to Cuticle Care
The application boundary of IOTA 25562 covers all personal care scenarios requiring "multi-compatibility + powder suspension + moisturization + gloss":
-
Color Cosmetics (Main Battlefield): Used as suspending aid in foundations, eyeshadows, blushes to prevent pigment settling and improve formulation stability; provides silky application and long-lasting wear.
-
Sun Care: Disperses organic UV filters, enhances SPF, reduces whitening, provides dry non-sticky sunscreen feel.
-
Face & Body Products: Used in creams, lotions, serums for wetting, moisturizing, and skin affinity, suitable for sensitive skin formulations.
-
Antiperspirants & Deodorants: As active carrier, improves spreadability and provides dry feel.
-
Cuticle Care: Used in conditioners, hair masks, leave-in serums to smooth cuticles, improve combability, and impart hair gloss.

Industry Insight: In personal care silicones, the molecular design of alkoxy ether modified polydimethylsiloxane — "alkoxy ether polar affinity + polyether chain wetting + polysiloxane backbone spreading" — is the key path to achieving the quadripartite unity of "multi-compatibility + powder suspension + moisturization + gloss" —
the introduction of alkoxy ether functional groups solves the industry pain point of traditional dimethicone: "multi-phase incompatibility", while the wetting and moisturizing of polyether chains end the application shortcoming of ordinary silicones: "insufficient powder suspension". IOTA 25562, with "INCI Bis-Hydroxyethoxypropyl Dimethicone + viscosity 40-60 mm²/s + refractive index 1.42 + alkoxy ether functional groups + polyether modification" hard metrics,
fills the key supply chain link for domestic alkoxy ether silicone in personal care (color cosmetics/sun care/face & body/antiperspirants & deodorants/cuticle care), providing a mass-producible refined high-performance silicone oil for downstream daily chemical enterprises. This confirms that domestic personal care silicones are leaping toward "dimethicone → polyether silicone → alkoxy ether silicone" in terms of multi-phase compatibility and sensorial experience, with growing technical say in high-end personal care fields.
