FAQ about sulfates

Do sulfates cause allergies?

Sulfates are not classified as allergens, but they can cause irritations, especially for individuals with sensitive skin.

What are the most commonly used sulfates?

The sulfates most commonly used in skincare are sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES).

What can be used as a substitute for sulfates?

Sulfates can be substituted with sugar derivatives such as glucosides or glutamates, which are gentler surfactants.

Do sulfate-free shampoos produce foam?

Yes, sulfate-free shampoos do produce foam, but in significantly lesser amounts than those with sulfates. However, this does not mean they are less effective.

How do sulfates work?

Sulfates function as surfactants: they enable the mixing of water and oils, thus aiding in the removal of impurities and sebum. When they come into contact with water, they produce foam, which assists in dissolving dirt and rinsing it away easily.
