How It Works

Laureth-7 is a nonionic surfactant with a water-loving PEG head and an oil-loving lauryl tail, so it sits at the oil–water interface, wrapping oil droplets to form and stabilize emulsions and to solubilize small amounts of oil into water.

Formulating with Laureth-7

Laureth-7 is used at low levels as an emulsifier/solubilizer, often with a co-emulsifier to reach the target HLB. Observe good manufacturing and preservation practice.

Safety Analysis

Laureth-7 is well tolerated at typical use levels. As always, substantiate the finished product’s safety (e.g. patch / HRIPT testing) in line with MoCRA requirements.
