Mechanism of Action
This ingredient forms a breathable, permeable film on the skin, a property characteristic of silicone resins. This film helps to lock in other ingredients, extend the wear of makeup by resisting transfer, and enhance water resistance in formulations such as sunscreens. Furthermore, like other silicones, it imparts a desirable 'slip' and a subtle sheen, improving the sensorial experience and spreadability of products.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined that Dimethiconyl Silicate, falling under broader categories of Dimethicone and Silicate ingredients, is safe for use in cosmetics as long as it is formulated to be non-irritating and, for products that may be incidentally inhaled, contains less than 0.1% crystalline silica or shows no adverse effects in repeated dose inhalation studies. Specific maximum concentrations for Dimethiconyl Silicate were not identified; however, related silicones have been used up to 85% and silica up to 44% in various cosmetic applications. The SCCS did not issue a firm safety decision for some nano-forms of silica due to insufficient evidence, but this does not directly apply to Dimethiconyl Silicate. There is no specific FDA status for this ingredient as a cosmetic additive.
