C12-14 Alketh-12

C12-14 Alketh-12 is a non-ionic surfactant derived from coconut or palm oil-based fatty alcohols. It functions as an emulsifier, helping to stabilise mixtures of oil and water-based ingredients that would otherwise separate. In skincare products, it allows formulators to create stable creams, lotions and serums with varied textures.This ingredient is relatively uncommon in skincare, appearing in fewer than 1% of formulated products. It is a gentler type of surfactant compared to harsher cleansing agents, making it better suited to leave-on skincare products rather than rinse-off cleansers.

Surfactants are molecules with one end that attracts water and another that attracts oil. C12-14 Alketh-12 positions itself at the boundary between oil and water phases, preventing them from separating and creating a stable emulsion. This is purely a functional role in the formulation rather than a treatment mechanism for skin.

This ingredient is not something you need to seek out or avoid based on efficacy; it serves a functional purpose in products rather than delivering active benefits. Simply use products containing it as directed by the manufacturer. It is well-tolerated in leave-on formulations at typical concentrations.

C12-14 Alketh-12 is generally well-tolerated in skincare products. Some individuals may experience mild transient irritation, though this is uncommon at the concentrations used in skincare formulations.
