This is due to the fact that the ingredients in laureth-4 may irritate the skin.
[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 Laureth-4.
