Description & Benefits

PEG-10 Dimethicone is a lipophilic polyether-polydimethylsiloxane copolymer with outstanding water-in-silicone (W/Si) and water-in-oil (W/O) emulsifying properties. It delivers a silky, non-sticky skin feel, making it ideal for premium personal care formulations. Its low operating temperature and ease of emulsification simplify production processes. The product appears as a colorless to yellowish, transparent to translucent liquid with a slight characteristic odor.

Applications
Widely used in:

• Skin care: Enhances texture and spreadability.

• Color cosmetics: Improves pigment dispersion and long-wear performance.

• Sun care: Stabilizes formulations with UV filters.

Usage Guidelines

1. Emulsification Process:

   • Thoroughly mix the oil phase and emulsifier before slowly adding the water phase under rapid stirring.

   • For liquid-based systems, room-temperature emulsification is feasible without homogenization; vigorous stirring ensures stability.

2. Stability Optimization:

   • Add electrolytes (e.g., 0.5–2% NaCl) to the water phase for improved storage stability.

   • Incorporate antifreeze agents (e.g., propanediol, glycerin) to enhance low-temperature resistance.

   • Adjust water content to modulate viscosity.

Recommended Dosage

• Primary Emulsifier: 1–4% of total formulation.

• Co-Emulsifier: 0.1–1.5% for synergistic stabilization.

Key Advantages

• Efficiency: Reduces energy consumption with low-temperature processing.

• Sensory Benefits: Imparts a smooth, luxurious finish.

• Versatility: Compatible with electrolytes and common cosmetic additives.

Ideal for formulators seeking high-performance, sensory-enhanced emulsions with streamlined production.
