Dimethyl Oxobenzo Dioxasilane is a silicone-based compound commonly used in cosmetic and personal care products for its film-forming, smoothing, and water-repellent properties. It is valued for its ability to enhance the texture and performance of formulations, providing a smooth, silky finish and improving product spreadability.

Chemical Composition and Structure:
Dimethyl Oxobenzo Dioxasilane is characterized by:

Dimethyl Groups: These contribute to the compound’s silicone characteristics and affect its film-forming abilities.
Oxobenzo Dioxasilane Core: Consists of a benzene ring with dioxasilane groups, which provide the compound's stability and film-forming properties.
Silicon-Oxygen Bonds: These contribute to its silicone nature and ability to create a flexible, breathable film on the skin.

The chemical structure includes a combination of silicon, oxygen, and carbon atoms arranged to allow for effective film formation and smooth application.

Physical Properties:
Dimethyl Oxobenzo Dioxasilane is typically a clear, colorless liquid with a slightly oily texture. It is non-volatile, meaning it does not evaporate quickly, and is soluble in other silicone and oil-based substances. It enhances the sensory feel of products, giving them a smooth and silky texture.

Production Process:

Synthesis: Dimethyl Oxobenzo Dioxasilane is synthesized through chemical reactions involving dimethyl silanes and benzoic acid derivatives.
Purification: The synthesized compound is purified to remove any residual impurities or by-products.
Formulation: The purified Dimethyl Oxobenzo Dioxasilane is incorporated into various cosmetic and personal care products during the formulation stage.

Applications:

Cosmetics: Used in products such as foundations, primers, and creams to improve texture, enhance spreadability, and provide a smooth, matte finish.
Skincare: Included in serums and lotions to create a protective, water-repellent layer on the skin, enhancing hydration and overall product performance.
Hair Care: Utilized in styling products to provide a sleek appearance, reduce frizz, and improve the manageability of hair.

Environmental and Safety Considerations:

Environmental Impact: The production of Dimethyl Oxobenzo Dioxasilane should adhere to sustainable practices, including efficient use of resources and proper waste management to minimize environmental impact.
Safety: Generally regarded as safe for topical use in recommended concentrations. Safety assessments should be conducted to ensure efficacy and to prevent any potential allergic reactions or adverse effects.

INCI Functions:


Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
