Question 1

What does TEA-Dodecylbenxenesulfonate do in a cosmetic formula?

Accepted Answer

This ingredient is an anionic surfactant used for cleansing, wetting, soil removal, and foam in rinse-off products. It brings strong detergency, so it is usually balanced with milder co-surfactants.

Question 2

Is TEA-Dodecylbenxenesulfonate clean?

Accepted Answer

From a clean-beauty perspective, it has friction because it is a relatively strong synthetic cleanser with higher eye and skin irritation potential than many amphoteric or nonionic alternatives. Formulators also need tight impurity controls around amine-related nitrosamine formation.

Question 3

Is TEA-Dodecylbenxenesulfonate sustainable?

Accepted Answer

This material is generally petrochemical-derived, made through sulfonation and neutralization rather than renewable, low-processing routes. Grades with a linear alkyl chain are typically biodegradable under aerobic wastewater conditions, but they can still add aquatic stress before treatment and dilution.

Question 4

Is TEA-Dodecylbenxenesulfonate COSMOS-approved?

Accepted Answer

It is generally not permitted in COSMOS natural or organic formulas because it is a synthetic petrochemical surfactant. Its Green Chemistry profile is mixed, with efficient performance at low active levels and biodegradability in linear grades, but limited renewable sourcing and more intensive chemical processing.

Question 5

How does TEA-Dodecylbenxenesulfonate work chemically?

Accepted Answer

The molecule combines an aromatic sulfonate anion, a C12 hydrophobic chain, and an amine-based counterion, which gives high water solubility, strong surface-tension reduction, and dense foam. It is typically used in rinse-off cleansing systems at low single-digit to mid-range active levels, is stable across mildly acidic to alkaline pH, and is generally incompatible with cationic conditioning polymers unless carefully formulated.
