SF‑1017｜Low‑Odor W/Si Emulsifier: The Stabilizer for Silicone‑in‑Water Cream Formulas

If you are seeking low‑odor, high‑activity polyether‑modified silicone for cold‑process cream formulations, SF‑1017 deserves a spot in your formulation portfolio.

Product Introduction

SF‑1017 is a polyether‑modified silicone surfactant developed by Topwin Technology. It functions primarily as a W/Si (silicone‑in‑water) emulsifier and is also compatible with W/O (water‑in‑oil) systems.

INCI Name: PEG‑10 Dimethicone Product Type: Low‑odor silicone emulsifier

As a linear polyether‑modified silicone with de‑odorizing treatment, it is optimized for cold‑process formulations. It features an HLB value of 4.5 tailored for W/Si systems. It exhibits excellent compatibility with silicone oils and delivers non‑sticky cream texture with silky‑smooth skin feel.

Key Benefits for Formulators

✅ Low odor & good storage stability: De‑odorized treatment prevents off‑odor generation during long‑term storage or high‑temperature ageing. ✅ Powerful emulsifying capacity: Blended with KSG series, it produces stable W/O face creams with high water loading. ✅ Refreshing skin feel: Generates relatively large water‑phase droplets for non‑greasy sensory performance. Low molecular weight brings non‑tacky creams without viscosity drop. ✅ Broad application scope: Suitable for skin care, color cosmetics, sun care, antiperspirants, hair care and pigment dispersion. ✅ Cold‑process friendly: Ideal for water‑break cream systems; drying time adjustable via volatile siloxanes. ✅ Excellent carrier performance: Serves as great carrier and spreading aid for emollients, humectants, UV filters, antiperspirant actives and pigments.

Recommended Dosage & Application Scenarios

• Recommended dosage: 0.1‑4 %; typical working dosage 0.5‑3 %; 2‑3 % for patented formulations.
• Typical applications: lotions, face creams, serums, foundations, eyeliners, sun‑care products, hair‑care items, pigment dispersion.

Stability Reference: Formulation with 3 % SF‑1017 remains homogeneous without phase separation after 90‑day storage at 45°C. Water dispersibility: >95 % dissolution rate in water at 25°C. 0.5 % loading forms uniform transparent system with no obvious sediment after 72 h.

Packaging & Storage

• Packaging: 25 kg plastic drum, 200 kg steel drum, 1000 kg IBC tank.
• Storage: Store sealed, protected from light in cool location below 25°C; keep away from heat and ignition sources.
• Shelf life: 12 months from delivery date under proper conditions.

Safety & Regulatory

Chemically stable under recommended handling and storage; no hazardous reaction reported.
