Science
Mechanism of Action
This ingredient operates by establishing a gas-permeable film on the skin's surface, effectively minimizing transepidermal water loss and shielding against environmental irritants. Its polyethylene glycol (PEG) chains confer humectant properties, enabling it to attract and retain water, thereby boosting skin hydration. Additionally, it contributes to a visibly smoother complexion by subtly filling fine lines and pores. Within formulations, PEG-6 Dimethicone acts as an emulsifier and wetting agent, ensuring the stability of oil-in-water mixtures and improving product spreadability.

Stability
Related compounds, such as PEG-12 Dimethicone, exhibit stability in neutral to mildly acidic or alkaline aqueous solutions. Stability is compromised by exposure to strong acids or strong alkalis. It can also serve as a plasticizer for hair resins and contributes to dense, stable foam in aqueous products.

Safety
Safety Profile
The CIR Expert Panel has affirmed PEG-6 Dimethicone (as part of the dimethicone copolyol class) as 'safe as used' in cosmetics. A comprehensive review confirmed the safety of dimethicone polymers when formulated to be non-irritating. However, data remains insufficient for uses involving incidental inhalation, such as airbrush applications, therefore Moumoujus recommends adherence to dermal contact applications only. The maximum reported concentration in dermal products is 85%.
