High-performance silicone emulsifier enabling stable, low-viscosity aqueous silicone dispersions.
Offers excellent compatibility with anionic, nonionic, and cationic systems in multi-component formulations.
Delivers superior film-forming capability and durable surface hydrophobicity on treated substrates.
Designed for easy incorporation—requires no high-shear mixing or pre-dilution for most applications.
Low foaming profile supports efficient processing in industrial coating, textile, and personal care manufacturing.
Textile softeners and fabric finish formulations for enhanced hand feel and wrinkle resistance.
Architectural coatings and exterior paints to improve water repellency and stain resistance.
Personal care emulsions including leave-on conditioners and skin protectant lotions.
Industrial maintenance coatings for concrete, masonry, and metal substrates.
Agrochemical adjuvants enhancing spray droplet retention and foliar coverage.

Q1: What is the primary function of DOWSIL FB-2540 in formulations?
A: DOWSIL FB-2540 is a ready-to-use silicone emulsifier blend designed to stabilize silicone-in-water emulsions, enabling uniform dispersion and improved compatibility of dimethicone and other non-polar silicones in aqueous systems.
Q2: In which types of end-use products is FB-2540 commonly applied?
A: It is widely used in personal care emulsions such as lotions, creams, and conditioners, as well as in industrial applications including textile softeners, coatings additives, and water-based release agents—where stable silicone delivery and sensory enhancement are required.
Q3: How should FB-2540 be incorporated into a formulation?
A: It is typically added during the aqueous phase or at the oil-in-water emulsification stage, with gentle mixing to avoid excessive shear. Pre-dilution with water or co-solvent may improve dispersion in high-viscosity systems.
Q4: Is FB-2540 compatible with common preservatives and electrolytes?
A: Yes, FB-2540 demonstrates good compatibility with a broad range of cosmetic preservatives (e.g., parabens, isothiazolinones) and moderate levels of electrolytes, though stability testing under final formulation conditions is recommended for critical applications.
Q5: What is the typical dosage range for effective emulsion stabilization?
A: Dosage depends on the silicone type, concentration, and desired emulsion stability, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the total formulation.
