Science
Mechanism of Action
This ingredient operates by establishing a non-occlusive, protective film on the skin's surface, which significantly reduces transepidermal water loss and sustains optimal hydration levels. Concurrently, it acts as a conditioning agent, bestowing a desirable softness and silky texture to both the skin and the formulation itself. Its ability to impart slip also aids in detackifying sticky components in a product.

Stability
For optimal stability, formulations should maintain a pH between 5.5 and 8.5. It is recommended to add the ingredient to the water phase, ensuring the temperature does not exceed 50°C (125°F). In emulsion systems, it can be integrated once the temperature has cooled to this threshold.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated related dimethicone and PEG-8 Dimethicone compounds, concluding safety for cosmetic use at concentrations up to 5.6%, provided products are formulated to be non-irritating. A specific caution is noted for products intended for airbrush application where incidental inhalation could occur.
