CHEMICAL ANALYSES – PRESERVATIVES

Cosmetic products are subject to European regulation, particularly in relation to any preservatives they may contain.
When they are put on the market, their ingredients are stated and the efficacy of their preservation system is challenge tested.
Following this, it is up to the laboratory that owns the brand to ensure that the product is always manufactured in the same way and that its composition is stable while consumers are using it.

Biogalenys provides analytical support in this area, and as such we check thousands of batches every year.

  • We check that the presence of controlled preservatives falls within regulatory limits.
  • We check the absence of preservatives that have been declared as not being present.
  • We check that manufacturers have complied with your specifications when quantifying the preservatives added.

These dosage checks are carried out in our laboratories using suitable and validated chromatography methods (HPLC-DAD, HPLC-UV, GC-MS-EI).

You can put your trust in our ISO 22716 and ISO 9001 accredited laboratory.
