- Phenyl Trimethicone is a derivative of silica, which is a natural component of quartz and opal.
- Phenyl Trimethicone is a white, silicone fluid. In cosmetics and personal care products, Phenyl Trimethicone is used in the formulation of a wide variety of products.
- Phenyl Trimethicone reduces the tendency of finished products to generate foam when shaken. It also enhances the appearance and feel of hair, by increasing hair body, suppleness, or sheen, or by improving the texture of hair that has been damaged physically or by chemical treatment.
- Phenyl Trimethicone slows the loss of water from the skin by forming a barrier on the skin’s surface.
Phenyl Trimethicone is considered a safe ingredient; the Cosmetic Database rates it as a low hazard and it is CIR approved, although data gaps are noted. Although silicone compounds can be toxic if ingested (and when injected, in some cases), and have been shown to cause allergic reactions in some studies, Phenyl Trimethicone, when applied topically in hair care and skin care products is generally considered safe.
