Dimethylsilanol Hyaluronic Ester, Silanized Hyaluronic Acid

Dimethylsilanol Hyaluronic Ester, Silanized Hyaluronic Acid

• Dimethylsilanol Hyaluronic Ester is a high-performance bio-silicone hybrid functional raw material modified by covalent grafting of dimethylsilanol groups on the basis of natural hyaluronic acid molecular skeleton.

• It breaks the limitation of traditional water-soluble hyaluronic acid that can only act on the skin surface and is easy to lose water. The product integrates the excellent transdermal hydration activity of hyaluronic acid and the hydrophobic film-forming stability of silicone groups, possessing unique amphipathic properties of lipophilic penetration and hydrophilic water locking.

• It can efficiently  penetrate the stratum corneum to replenish basal skin moisture, while forming a uniform, soft and breathable hydrophobic protective film on the skin surface. Different from conventional HA which fails in humid and dry environments, this silicone-modified HA derivative has outstanding water resistance and long-lasting moisturizing performance, which can stably lock skin moisture for a long time, reduce transepidermal water loss, strengthen the expression of skin barrier proteins, repair damaged fragile skin, and relieve dryness, redness and sensitivity.

• With mild biological activity, excellent system compatibility and no irritation, it is an upgraded core moisturizing and repairing raw material for long-acting stable skincare and long-wear comfortable makeup formulas.

Key Benefits

• Silicone-modified Amphipathic Structure, Dual-layer Hydration: Unique lipophilic silicone group assists transdermal penetration, hydrophilic HA skeleton locks water in depth, realizes dual-layer skincare of basal water replenishment and surface water locking, far exceeding the single surface moisturizing effect of traditional HA.

• Waterproof & Long-lasting Moisturizing, No Dry Rebound: The hydrophobic silicone film avoids moisture evaporation and external water washing loss, maintains stable skin hydration in dry air-conditioned rooms and humid sweaty environments, solves the problem of easy dry rebound of ordinary hyaluronic acid.

• Strengthen Skin Barrier & Repair Sensitivity: Effectively up-regulates skin barrier protein content, repairs damaged stratum corneum, relieves dryness, tightness, redness and sensitivity, improves skin tolerance, and is suitable for fragile sensitive skin care systems.

• Compatible with Oil-water Dual-phase, Wide Formula Adaptability: Different from single water-soluble traditional HA, it has both lipophilic and hydrophilic properties, can be stably dispersed in water phase, oil phase and emulsion systems, solving the compatibility problem of HA in oil-based formulas.

• Improve Makeup Fitting & Prevent Dry Caking: Forms a smooth and breathable moisturizing base film on the skin surface, optimizes skin smoothness, effectively improves foundation fitting degree, prevents dry lines, floating powder and caking, and enhances long-wear makeup comfort.

• High Safety & Mild Biological Activity: Natural HA matrix + inert silicone modification, non-irritating, low allergenic, non-comedogenic, retains the biological soothing activity of hyaluronic acid, compliant with clean and mild skincare standards.

Frequently Asked Questions (FAQ)

• Q1: What is the core difference between silanized HA and ordinary hyaluronic acid? 

A1: Ordinary HA is purely water-soluble, only moisturizes the skin surface, and is easy to lose water and fail when encountering water or dry environment. Dimethylsilanol Hyaluronic Ester adopts silicone graft modification, with amphipathic solubility and hydrophobic film-forming property. It realizes transdermal deep hydration and waterproof long-lasting water locking, with moisturizing duration 2-3 times that of traditional HA, and has unique barrier repair advantage.

• Q2: What is the recommended formula addition ratio? 

A2: 0.1%-0.5% for moisturizing skincare essence/lotion, 0.2%-0.6% for barrier repair products, 0.1%-0.4% for long-wear base makeup, 0.1%-0.3% for sunscreen products, adjustable according to formula moisturizing strength and long-acting maintenance requirements.

• Q3: Is it suitable for oily and sensitive skin formulas? 

A3: Yes. The product has light texture, breathable film formation without greasiness, can regulate skin water and oil balance, will not cause oil accumulation and stuffy skin. Its mild repair activity can soothe sensitive skin and strengthen barrier, suitable for all skin types including oily skin and fragile sensitive skin.

• Q4: Can it be compounded with traditional HA series? 

A4: Absolutely yes. It can be perfectly compounded with macromolecular, medium and small molecular hyaluronic acid, acetylated HA and hydrolyzed HA to build a three-dimensional layered moisturizing system of surface locking, middle layer nourishing and deep penetration, realizing full-dimensional long-acting hydration and repair.

• Q5: Why can it improve makeup endurance? 

A5: It forms a smooth and breathable moisturizing protective film on the skin surface, which can continuously replenish and lock water, prevent the skin from drying and shrinking during long-term makeup wearing, effectively avoid dry lines, floating powder and caking, and significantly improve the docility and durability of base makeup.

• Q6: Does it support stable bulk supply and technical services? 

A6: Standardized high-end cosmetic grade modification production with stable grafting rate, solubility and moisturizing activity, sufficient inventory, supports long-term bulk supply and global export, and provides professional formula debugging, layered moisturizing system optimization and barrier repair effect customization technical support.
