Trideceth-10

Trideceth-10 is a non-ionic surfactant derived from tridecyl alcohol. It functions as a cleansing agent in skincare formulations, helping to remove excess sebum, makeup, and environmental debris from the skin's surface.As a mild surfactant, it works by reducing the surface tension between water and oil-based substances, allowing them to mix and rinse away. It appears in roughly 0.4% of skincare products, typically in cleansers and micellar solutions where its gentle nature suits sensitive formulations.

Trideceth-10 is a non-ionic surfactant, meaning it carries no electrical charge. This structure makes it less likely to disrupt the skin's natural barrier compared to harsher anionic surfactants. It works by surrounding oil molecules and allowing them to be rinsed away with water, without leaving behind a heavy residue.Because it is non-ionic, it tends to be milder and better tolerated by sensitive skin types, making it a favoured choice in gentle cleansing formulations.

Trideceth-10 is typically encountered in cleansing products rather than leave-on treatments. Use as directed on the product label—usually as part of a twice-daily cleanse. For sensitive skin, you may prefer products containing this ingredient over harsher surfactants, as it is formulated to minimise irritation.

Trideceth-10 is generally well-tolerated and considered safe for cosmetic use. It is non-ionic and milder than many alternative surfactants, making it suitable for sensitive skin.
