Brief description: Dimethicone, also known as polydimethylsiloxane (PDMS), is a type of silicone oil that's widely used in cosmetic products. It provides a smooth, silky feel and helps to form a protective barrier on the skin or hair.

Benefits: Conditions and protects the hair and skin, reduces frizz, enhances shine, provides a smooth feel, and helps to prevent moisture loss.

Skin type suitability/concerns: Suitable for all hair and skin types. Particularly beneficial for dry or damaged hair and dry or sensitive skin.

Target audience: Anyone looking for improved hair manageability, skin hydration, and a smoother feel to hair or skin.

Chemical composition: Dimethicone is a silicone-based polymer, specifically a linear silicone oil that is polymerized siloxane.

Physical aspect: It's a clear, odorless, and tasteless viscous oil. In cosmetic products, it's incorporated into a wide range of formulation types, from creams and lotions to serums and conditioners.

Compatibility: Compatible with most other ingredients used in cosmetic formulations. It's particularly effective when used in combination with other conditioning and moisturizing ingredients.

Concentration: The concentration can vary depending on the product type and desired effect, but it's often used at levels between 1% and 10% in cosmetic formulations.

Side effects/adverse reactions: Generally considered safe and non-irritating. However, some people with sensitive or acne-prone skin may find that it causes breakouts or irritation, particularly at high concentrations or in leave-on products.

Regulatory status: Considered safe for use in cosmetics by the FDA and the CIR Expert Panel.

Sustainability/ethical considerations: Dimethicone is synthetically derived. While there are no major ethical concerns related to its production, silicones have raised some environmental concerns due to their non-biodegradable nature.
