It foam at POLYMEX

"Sulfate free" - What if we checked ??


Sulfates are very common in the formulation of our shampoos, shower gels and hygiene products for their foaming properties, but also their low production cost.

These compounds are today in turmoil and are the subject of various controversies. They are now classified as "aggressive" surfactants, irritating to the skin and scalp.
Many products thus refers to a formulation "Without sulfates," but are they really "sulfate free"?


Thanks to its UPLC / TOF-MS, the Polymex laboratory can offer you a broad screening of your hygiene products, in particular sulphates known as "Aggressive":
- SLS - Sodium Lauryl Sulfate [151-21-3]
- SLES - Sodium Laureth Sulfate [9004-82-4]
- ALS - Ammonium Lauryl Sulfate [2235-54-3]
- SMS - Sodium Myreth Sulfate [25446-80-4]
- SLSA Sodium Lauryl Sulfoacetate [1847-58-1]
- ...

Whether your research is on a Sulfate, or any other chemical family of surfactant type,
the POLYMEX team is at your disposal to best solve your problems!
