Concern level
High concern
Octyldodeceth-16 is a nonionic ethoxylated fatty alcohol (PEG/ether surfactant) used mainly as an emulsifier, solubilizer, and texture-enhancing agent in cosmetic formulations. It helps blend oil and water phases and can improve spreadability and product feel. It is generally considered low-risk and is typically used in rinse-off and leave-on products at low to moderate levels.

Interactions
incompatible with: No major direct ingredient incompatibilities are established, May be less desirable in formulas intended for extremely irritated or compromised skin if used at higher levels, As a nonionic surfactant, performance can be affected by very high electrolyte loads or extreme pH
Risks & Warnings
Generally low hazard when formulated non-irritating, but as a PEG-derived surfactant it may cause mild irritation in very sensitive skin, especially at higher concentrations or in compromised-barrier products. Like many ethoxylated ingredients, it is not ideal in products requiring very high purity control if manufacturing contamination is a concern.
