Ceteth-24

Ceteth-24 is a non-ionic surfactant derived from cetyl alcohol, a fatty alcohol commonly used in skincare. It functions as a cleansing agent and emulsifier, helping water and oil-based ingredients blend together smoothly in formulations.In cleansing products, it works to lift away dirt and oil from the skin's surface without the harshness associated with stronger detergents. Its mild nature makes it suitable for regular use across a range of skincare categories, from gentle cleansers to moisturisers.

Ceteth-24 is a surfactant, meaning it has a dual nature: one end attracts water while the other attracts oil. This allows it to surround oil and dirt particles on the skin, suspending them so they can be rinsed away during cleansing.In formulations, it also acts as an emulsifier by stabilising the mixture of water and oil-based ingredients, preventing them from separating. This dual role makes it a workhorse ingredient in both rinse-off cleansers and leave-on skincare products.

Ceteth-24 is typically found in cleansing products that you would use during your daily routine — simply follow the instructions on the product label. In most formulations, it is one of several ingredients working together, so you do not need to adjust its use based on concentration. If using a cleanser containing this ingredient, follow with a moisturiser appropriate for your skin type.

Ceteth-24 is generally well-tolerated and approved for use in cosmetics across most regulatory bodies. Some individuals with significant sensitivity may occasionally experience mild irritation, though this is uncommon.
