Mechanism of Action
Octoxynols, including Octoxynol-6, exert their effects by acting as surfactants. They reduce the surface tension of substances, which facilitates the formation of stable emulsions. Additionally, they enhance cleaning by allowing water to effectively mix with oil and dirt, enabling easier rinsing from skin and hair.

Key findings
- 01 In a 24-hour occlusive patch test, formulations containing 2% Octoxynol-9 were classified as moderately to minimally irritating.
- 02 Octoxynol-9 at a 1% concentration was classified as a nonirritant in a clinical study involving nine subjects patch tested over 4 consecutive days.

Safety
Safety Profile
The CIR Expert Panel considers Octoxynol-6 safe for use in rinse-off products and safe at concentrations of 5% or less in leave-on formulations. However, particular caution is advised: short-chain octoxynols (including Octoxynol-6) should be avoided in products for the eye area due to potential ocular irritancy. Products must be formulated to ensure non-irritation, and trace impurities such as 1,4-dioxane and ethylene oxide should be rigorously minimized.
