Bis-PEG/PPG-16/16 PEG/PPG-16/16 Dimethicone

What is Bis-PEG/PPG-16/16 PEG/PPG-16/16 Dimethicone?

Bis-PEG/PPG-16/16 PEG/PPG-16/16 Dimethicone is a synthetic silicone polyether, consisting of dimethicone (polydimethylsiloxane) with bis(PEG/PPG-16/16) chains attached to both ends. This structure blends hydrophobic silicone properties with hydrophilic PEG/PPG segments, enabling water dispersibility and compatibility in diverse formulations. Primarily used in rinse-off and leave-on cosmetics like shampoos, conditioners, lotions, and creams, it functions by reducing surface tension for better spreading, stabilizing oil-water emulsions through interfacial film formation, and delivering emollient effects that enhance skin and hair softness without residue. Its surfactant capabilities support gentle cleansing, while the conditioning action improves texture and flexibility, making it ideal for multi-phase products requiring stability and sensory appeal.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Skin conditioning agent

Maintains skin softness, smoothness, and flexibility.

Surfactant

Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.

Emulsifying agent

Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Emollient

Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.

Benefits

Enhances skin smoothness and softness for a silky feel.

Stabilizes emulsions to maintain consistent product texture.

Supports effective cleansing with low surface tension.
