SF‑1090: Classic High‑Performance Water‑in‑Oil Emulsifier, an All‑Rounder for Formulators

Product Overview

SF‑1090, INCI name: Cetyl PEG/PPG‑10/1 Dimethicone, is a non‑ionic silicone‑based W/O emulsifier.

Key Advantages

• High emulsification efficiency at low dosage: Stable W/O emulsions achieved with only 1.5%‑2.5% addition level
• Silky skin feel: Delivers light‑weight, non‑tacky sensory experience upon application
• High compatibility with actives: Great compatibility with vegetable oils, UV filters and botanical extracts
• Outstanding heat‑freeze‑thaw stability: Works reliably from ‑25 ℃ to +60 ℃
• Co‑emulsifier‑free system: No additional co‑emulsifier required; small amount of wax can be added to boost viscosity
• Compatible with diverse cosmetic oils: Easily emulsifies mineral oils, ester oils and silicone oils
• Liquid at room temperature: No melting by heating required for convenient handling

Application Performance: From Sun Care to Foundation

1. W/O Creams & Lotions

SF‑1090 excels at producing light‑weight W/O lotions. It works for formulas with or without mineral oil esters, and shows good tolerance to high‑load vegetable oils and active ingredients. Recommended dosage: 1.5%‑2.5% based on total emulsion weight. No co‑emulsifier needed. Up to 2% thickening wax (hydrogenated castor oil, high‑melting hydrocarbon wax or beeswax optional) can be incorporated. Optimal oil‑phase loading ranges 22%‑35%.

2. Multiple Emulsion Systems

SF‑1090 supports manufacturing of W/O/W and O/W/O multiple emulsions. Its polymeric structure significantly improves interfacial stability, which is valuable for sustained‑release skin care and functional cosmetics.

3. Sun Care Products

It efficiently emulsifies formulas loaded with high levels of organic and physical UV filters, ideal for sunscreen creams and lotions. Suggested dosage in sun‑care formulas: 1.5%‑3.5%. For example, 1.50% SF‑1090 combined with multiple UV filters and oils delivers high‑protection performance in SPF50+ PA++++ sunscreen.

4. Foundation & Color Cosmetics

In W/O foundation formulas, SF‑1090 helps resist sweat‑triggered makeup removal while maintaining light skin feel, suitable for sports‑use cosmetic products.

Why Choose SF‑1090?

Within the W/O emulsifier market, SF‑1090 combines powerful emulsifying capacity with premium sensory performance. Conventional W/O emulsifiers often result in heavy, greasy texture. Thanks to its silicone‑based polymeric structure, SF‑1090 secures emulsion stability while offering light, silky skin feel — a highly desired feature for premium skin‑care and sun‑care items.

Moreover, broad oil compatibility and co‑emulsifier‑free simplicity expand formulation flexibility for cosmetic chemists. It is a reliable classic option for premium sunscreen, skin‑friendly foundation and functional multiple‑emulsion development.
