Hydroxypropyl Dimethicone Behenate

Product Description

Hydroxypropyl Dimethicone Behenate is an advanced silicone-wax hybrid polymer, synthesized as a high-purity functional ingredient for the premium B2B cosmetic market. By grafting behenic acid (C22 fatty acid) onto a silicone backbone, this material bridge the gap between silicone silkiness and the protective barrier properties of natural waxes. As modern formulations trend toward "long-wear" and "breathable barrier" technologies, this direct factory supply ingredient provides formulators with a non-greasy, high-melting-point solution for skin-adherent textures.

Key Benefits & Applications

• Unique Sensory Hybrid: Delivers the initial slip and cushion of silicones followed by the lasting, velvety after-feel of premium waxes.
• Moisture Lock & Barrier Support: Forms a hydrophobic, breathable film that prevents trans-epidermal water loss (TEWL) without the heaviness of petrolatum.
• Pigment Dispersion: Excellent compatibility with inorganic filters (ZnO/TiO2) and color pigments, improving the stability and spreadability of sunscreens and foundations.
• Stick Strengthening: In lipsticks and stick deodorants, it enhances structural integrity while providing a smooth, "no-drag" application experience.
• Wash-off Resistance: Increases the durability of sun care and protective hand creams against water and friction.

Formulation Guidelines

• Recommended Usage: 1.0% – 5.0% depending on the desired texture and barrier effect.
• Incorporation: Should be added to the oil phase and heated to 50°C – 60°C to ensure complete melting and uniform blending.
• Stability: Chemically inert and highly resistant to oxidation compared to pure vegetable waxes.
• Compatibility: Widely compatible with dimethicones, cyclomethicones, and a variety of cosmetic esters and oils.
• Synergy: Combine with Ceramide NP to reinforce the skin's lipid barrier while providing an elegant, smooth protective seal that prevents moisture evaporation.
