Uses of Laureth-7 in cosmetics

Laureth-7 acts as an emulsifier and surfactant.

Emulsifier

Emulsifier

Emulsifiers are necessary for products containing oil and water, you can easily imagine how oil and water mix together when we shake vigorously they will disperse oil or water droplets but when stopped they stop detached.

To solve this problem, an emulsifier will be added to the mixture to help the droplets disperse and create a stable emulsion. Laureth-7 has the property of being one hydrophilic and one hydrophobic, the hydrophilic head towards the water phase and the hydrophobic end towards the oil phase.

This helps laureth-7 to reduce surface tension by keeping itself in place at the oil, water or air interface, which has a stabilizing effect on the emulsion.

Surfactants

Surfactants

Laureth-7 also functions as a surfactant, which can reduce the surface tension between two compounds such as solid and liquid. In cosmetics, this substance has the function of reducing and emulsifying oils and fats, removing dirt.

Laureth-7 can attract oil, dirt, and other impurities that accumulate on the skin and clean them. Because of this function, laureth-7 is found in many detergents and shower gels.

The Cosmetic Review Panel (CIR) has concluded laureth-7 is safe only when used in non-irritating cosmetics, so it has the potential to cause skin irritation.

In particular, the ethoxylation process can contaminate 1,4-dioxane, which is a carcinogen in animals, and also causes skin allergies.

According to a study by the Environmental Working Group (EWG) , a famous American environmental working group rated Laureth-7 with a score of 3 out of a total of 10 points, in which 1 point is the lowest level of health hazard, level 10 is the highest level.
