Science

Mechanism of Action

This ingredient functions as a surfactant by effectively reducing the surface tension of a formulation, facilitating the mixing of oil and water. As a cleansing agent, it encapsulates oil and dirt particles, enabling their removal from the skin. It also acts as a conditioning agent, an emollient to soften, and an emulsifier to stabilize formulations, with additional benefits as a foam booster, hydrotrope, and antistatic agent. It may offer antioxidant benefits by helping to mitigate oxidative damage.

Sensitization risk Moderate

The CIR Expert Panel considers this ingredient safe for cosmetic use when formulated to be non-sensitizing. It is deemed safe for rinse-off products at concentrations up to 4.0%. However, due to insufficient dermal penetration data, it is considered unsafe for leave-on products. Concerns exist regarding impurities, such as 3,3-dimethylaminopropylamine (DMAPA), and the potential sensitizing nature of related compounds. High concentrations have been associated with moderate skin irritation and severe eye irritation in animal studies.
