Sulfates in cosmetics: understanding, choosing and protecting your skin
"Sulfate-free": this statement has become an essential selling point on the labels of shampoos, shower gels and facial cleansers.
But do you really know what lies behind this term?
Sulfates are often singled out… sometimes wrongly, sometimes rightly.
In this article, we will:
- Explain precisely what sulfates are and their role in cosmetics.
- Separating fact from fiction about their effects on skin and hair
- Helping you know when and how to avoid them
- To show you how Cattier uses them expertly and safely
Sulfates: powerful and ubiquitous cleaning agents
Sulfates belong to the family of surfactants, molecules capable of trapping impurities and sebum so they can be rinsed away with water. They are valued for their foaming power and cleansing effectiveness, which explains their presence in many cleansing products: shampoos, shower gels, toothpastes, and also facial cleansers.
In conventional cosmetics, they provide a quick and pleasant wash, with abundant lather that gives an immediate feeling of cleanliness. But this effectiveness has a downside: if used incorrectly or alone, sulfates can weaken the hydrolipidic film of the skin and hair.
Why do they have a bad reputation?
Their detergent power, which is their strength, can also become a weakness: by removing too many protective lipids, sulfates can cause dryness, tightness, itching, or even redness.
Analysis apps like Yuka or INCI Beauty often flag products containing sulfates as "mediocre", without always distinguishing their origin or formulation context.
However, when they are of plant origin and combined with milder surfactants, they can be perfectly well tolerated.
The problem therefore lies not only in their presence, but in their quality, dosage and combination with other ingredients.
When and why should we limit sulfates?
Certain situations require greater vigilance:
- Colored hair, because sulfates can accelerate color fading.
- Curly or very dry hair is naturally more fragile.
- Atopic or ultra-sensitive skin, for which a very gentle cleanser is preferable on a daily basis.
In these cases, choosing a sulfate-free cleansing base or one with very gentle plant-based surfactants can preserve skin hydration and comfort.
Sulfates in organic cosmetics: another approach
Contrary to some misconceptions, organic cosmetics do not systematically exclude sulfates.
Labels like COSMEBIO allow the use of Sodium Lauryl Sulfate (SLS) and Ammonium Lauryl Sulfate (ALS) of plant origin, obtained via environmentally friendly processes and without ethoxylation.
These plant-based versions, made from raw materials such as coconut or palm kernel oil, are biodegradable, less aggressive and integrated into balanced formulas that limit any risk of irritation.
Conversely, Sodium Laureth Sulfate (SLES), produced using an ethoxylated process, is prohibited in organic-labeled formulas for environmental and health reasons.
Cattier's expertise: efficiency, gentleness and safety
At Cattier, our expertise of over 55 years allows us to use sulfates in just the right measure. We systematically combine them with gentle surfactants and protective active ingredients such as organic aloe vera, wheat protein or honey, in order to preserve the balance of skin and hair.
All our products undergo rigorous dermatological and ocular testing.
And because every skin is unique, we also offer a sulfate-free range to meet the needs of even the most sensitive skin and scalps, without compromising on the pleasure of use.
In summary: what you need to remember
Sulfates are not the enemies we imagine. Their tolerability depends primarily on their origin, their dosage, and the overall formulation of the product.
By choosing organic or well-formulated skincare products, you benefit from their cleansing effectiveness while respecting your skin and hair.
