Your essential ingredient

Glyoxo HighPure 50 is a high-performance semi-permanent hair straightener, removing the toxicity associated with formulations featuring formaldehyde, traditionally used in hair-care.


Glyoxylic Acid reacts with the amino groups present in Keratin, delivering a straightening effect without damaging hair or irritating skin. It gives your customers a semi-permanent smooth look and feel for a longer period of time.

It also allows you to leverage the “Free-of-Glyoxal” grade for cosmetics regulations in your formulations, creating higher-performing and more consumer-friendly products.
