Bis-PEG/PPG-14/14 Dimethicone

What is Bis-PEG/PPG-14/14 Dimethicone?

Bis-PEG/PPG-14/14 Dimethicone is a synthetic silicone polyether copolymer derived from polydimethylsiloxane modified with polyethylene glycol (PEG-14) and polypropylene glycol (PPG-14) chains on both ends. Produced through polymerization of siloxanes with ethylene oxide and propylene oxide, it is water-dispersible and commonly incorporated into skincare, haircare, and color cosmetics. In formulations, it acts by lowering surface tension to promote wetting and spreading, creating stable oil-in-water emulsions, and forming lightweight films that deliver a non-greasy, velvety texture. This multifunctional ingredient supports even distribution of active components, improves product playtime during application, and contributes to conditioning effects on skin and hair surfaces, making it ideal for lotions, serums, shampoos, and foundations.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

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.

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.

Skin conditioning agent

Maintains skin softness, smoothness, and flexibility.

Benefits

Delivers a silky, smooth application feel while softening skin texture.

Stabilizes emulsions for consistent lotion and cream consistencies.

Supports skin conditioning to promote a flexible, supple surface.
