Phenyl trimethicone is a silicone derivative used in cosmetics and personal care products. It is safe for use as per Cosmetic Ingredient Review (CIR) and has a low hazard rating from the Environmental Working Group (EWG). It reduces foam formation, enhances hair appearance, and acts as a skin conditioning agent. Phenyl trimethicone is a derivative of silica and belongs to the siloxane group of chemicals. It functions as a hydration-sealing occlusive and conditioning agent, contributing to a product’s silky texture and feel on skin.
Hydration: Phenyl trimethicone helps to keep skin hydrated by forming a barrier on the skin's surface that slows the loss of water. Non-oily emollient: It provides a non-greasy, velvety feel to the skin without clogging pores. Anti-whitening properties: Phenyl trimethicone is used in antiperspirants to prevent the formation of white residue. Spreadability: It improves the spreadability and application of skincare products. Compatibility: Phenyl trimethicone is compatible with a wide range of other ingredients, making it easy to formulate with. Film forming: It forms a thin, protective film on the skin that helps to seal in moisture and protect against environmental stressors. Water repellency: Phenyl trimethicone has water-repellent properties that help to keep skin dry in humid conditions. Softness: It imparts a soft, silky feel to the skin. Silkiness: Phenyl trimethicone gives hair a silky, shiny appearance.

Phenyl trimethicone is used as an antifoaming agent, hair conditioning agent, and skin conditioning agent – occlusive in cosmetics and personal care products. It has a higher viscosity and a drier finish than some other silicone ingredients. Phenyl trimethicone is often used to enhance the texture of a product, contributing to a product’s silky feel on the skin and reducing the tackiness and stickiness in creams and lotions. Furthermore, phenyl trimethicone allows for even distribution of active ingredients on the skin surface. Phenyl trimethicone has a drier finish than dimethicone, another common silicone used in skincare products, making it a great for formulations that shouldn’t be sticky or tacky. Phenyl trimethicone provides heat resistance in haircare applications, as well as non-oily "emolliency and anti-whitening properties in antiperspirants" (National Institutes of Health). It also slows the loss of water from the skin by forming a barrier on the skin’s surface.
