INCI:Â Dimethicone
Dimethicone, a polydimethylsiloxane, is a clear, colorless, and odorless silicone oil available in various viscosities. Its chemical structure features repeating dimethylsiloxane units, forming a linear polymer. This versatile silicone is known for its inert nature, meaning it does not react with other ingredients, and its non-comedogenic properties make it ideal for acne-prone or sensitive skin.
Dimethicone serves multiple functions in personal care formulations. It acts as an emollient, providing a silky, velvety texture to the skin while forming a hydrophobic barrier that repels water and retains moisture. In hair care, it conditions and improves hair texture and manageability. Additionally, dimethicone smooths formulations, reducing the appearance of fine lines and wrinkles. Its heat-resistant and stable nature ensures consistent performance, making it a valuable ingredient in both skincare and hair care products.
Chemical Structure:
Physical Form:
Benefits:
Inert Nature: Dimethicone is chemically inert, meaning it does not react with other ingredients in formulations.
Non-Comedogenic: It is non-comedogenic, making it suitable for formulations targeting individuals with acne-prone or sensitive skin.
Hydrophobic: Dimethicone is hydrophobic, creating a barrier on the skin that helps to repel water.
Heat Resistance: It exhibits high-temperature stability.
Emollient: Dimethicone is widely used as an emollient to soften and smooth the skin. It imparts a silky and velvety texture.
Occlusive Agent: Its hydrophobic nature makes dimethicone effective as an occlusive agent, forming a protective barrier on the skin to reduce water loss and enhance moisture retention.
Conditioning Agent: In hair care products, dimethicone provides conditioning benefits, improving the texture and manageability of hair.
Surface Smoothing: Dimethicone contributes to the smoothness of formulations, minimizing the appearance of fine lines and wrinkles.
Dimethicone is a versatile ingredient found in a wide range of personal care and cosmetic products, including moisturizers, lotions, creams, sunscreens, hair conditioners, and makeup products.
While generally well-tolerated, individuals with a history of silicone sensitivity may want to perform patch tests.
Store in a cool, dry place away from direct sunlight. Ensure the container is tightly closed when not in use to prevent contamination and moisture absorption.
