New aryl alkenone from Sytheon
Sytheon has expanded its range of aryl alkanones with the launch and patenting of Synoxyl AZ (INCI: Methyl Acetyl Zingerone).
This has a phenolic function and can selectively chelate iron and copper ions but not the skin- and scalp-friendly zinc or calcium ions, thus reducing the oxidising Fenton reaction.
According to Sytheon, aryl alkanones are the first products in this category identified with selective chelating ability, which can protect hair fibres and the scalp by reducing the oxidative stress generated during hair dyeing, as well as bleaching, repeated shampooing, perming or other oxidative treatments.
This is the third patent the company has taken out. The last before it, in December 2020, was for Synoxyl AZ (INCI: Acetyl Zingerone), which disclosed a formulation of one or more aryl alkanones, at least one other skin lightening agent (optional) and a dermatologically acceptable carrier to even skin tone and lighten normal and/or hyperpigmented skin.
