LAURETH-4 Chemical Properties,Usage,Production

Description

Laureth-4 is a synthetic polymer used in a number of different cosmetic and skin care products using to improve the texture and feel of formulations. It is primarily used as a surfactant and emulsifier. It can be found in products such as bath, cleansing, hair and sunscreen products. It is also used in cuticle softeners, deodorants and moisturising products.

Chemical Properties

Laureth-4 is a defoamer, and it is non-toxic, odorless, non-irritating, and has a hard water and acid and alkali resistance, and a excellent compatibility. Also its antifoaming performance is quite good .

Uses

Laureth-4 can be used as an antistatic agent and emulsifier in cosmetics, but it has a high possibility of causing skin irritation and acne.

Flammability and Explosibility

Not classified

Safety

Developmental toxicity, multigenerational and fertility data and mutagenicity data for Laureth-4 were negative. The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Laureth-4 can only be used in cosmetics when formulated to be non-irritating can be safely used in cosmetics. 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.
