Question 1

What does SODIUM LAURETH-12 SULFATE do in a cosmetic formula?

Accepted Answer

This ingredient is a primary anionic surfactant used to create foam, lift oil and soil, and drive cleansing performance in shampoos, body washes, and facial cleansers.

Question 2

Is SODIUM LAURETH-12 SULFATE clean?

Accepted Answer

From a clean-beauty perspective, it has friction because it surfactants can be drying or irritating for some users, especially at higher active levels. It is also ethoxylated, so clean standards often scrutinize residual 1,4-dioxane and ethylene oxide control.

Question 3

Is SODIUM LAURETH-12 SULFATE sustainable?

Accepted Answer

This material is typically made from a fatty alcohol source that may be coconut, palm, or petrochemical-derived, plus petrochemical ethylene oxide. It is generally biodegradable, but its palm-linked sourcing and aquatic surfactant load create sustainability caveats.

Question 4

Is SODIUM LAURETH-12 SULFATE COSMOS-approved?

Accepted Answer

It is not generally aligned with COSMOS-natural or COSMOS-organic because ethoxylated ingredients are not accepted in those standards. Its biodegradability helps its Green Chemistry profile, but petrochemical processing and residue controls keep it outside strong natural-standard alignment.

Question 5

How does SODIUM LAURETH-12 SULFATE work chemically?

Accepted Answer

The molecule has a C12-rich fatty alcohol tail, an average of about 12 ethoxy units, and a terminal it salt, which gives it strong anionic character and high water solubility. It is commonly used in rinse-off cleansers at roughly 5 to 20% active surfactant, with viscosity often adjusted through salt and amphoteric co-surfactants.
