Tridecyl alcohol (CAS 27458-92-0, C13H28O) is a C13 fatty alcohol, commonly supplied as the branched oxo isomer isotridecanol. It is used as a surface-active agent, a lubricating agent, and a fragrance ingredient.

Frequently Asked Questions

What is tridecyl alcohol used for?

Tridecyl alcohol (CAS 27458-92-0, C13H28O) is a C13 fatty alcohol used as a surface-active agent and surfactant feedstock, a lubricating-agent additive, and a fragrance ingredient and emollient.

What is isotridecanol used for?

Isotridecanol is the branched oxo isomer of tridecyl alcohol and is the common commercial form. It is used as a surfactant feedstock (notably for alcohol ethoxylates), a lubricant additive, and a fragrance/emollient ingredient.

What is tridecyl alcohol ethoxylate used for?

Ethoxylating tridecyl alcohol produces alcohol ethoxylate nonionic surfactants (the trideceth series), used as wetting agents, emulsifiers, and detergents. Tridecyl alcohol itself is the C13 feedstock for that ethoxylation.

Is tridecyl alcohol the same as tridecane?

No. Tridecyl alcohol (C13H28O) is a C13 fatty alcohol with a hydroxyl group, whereas tridecane (C13H28) is the corresponding saturated hydrocarbon with no oxygen. They are different compounds with different CAS numbers and uses.

How do I source bulk tridecyl alcohol?
