Uses
C 16 C 18 - FATTY ALCOHOL 25 EO can be used as an antistatic agent and emulsifier in cosmetics, but it has a high possibility of causing skin irritation and acne.
C 16 C 18 - FATTY ALCOHOL 25 EO, 7 moles is a non-ionic surfactant belonging to the ethoxylated fatty alcohol group.
C 16 C 18 - FATTY ALCOHOL 25 EO is part of a group of surfactants based on lauryl alcohol with C12-C14 carbon distribution.
The ethoxylation process also tends to increase the water solubility of the material.
Products that typically contain C 16 C 18 - FATTY ALCOHOL 25 EO include cosmetics, laundry detergents, surface cleaners and personal care products.
Synthesis
KOH（1g） and dodecanol (24.8 g ) were heated to 85° C in the reactor, then vacuumed and filled with nitrogen for 2 to 3 times.
The mixtrue was heated to 120 ℃～130℃, and added with ethylene oxide (EO), propylene oxide (PO) or their mixture.
After the reaction is completed, the solution was neutralized with H2SO4(98%) and filtered to give C 16 C 18 - FATTY ALCOHOL 25 EO.
