AkzoNobel Surface Chemistry has introduced Recentia plant serum fractions, a new line of bioactive ingredients based on cutting-edge Zeta Fraction technology. With conventional plant extraction, botanical extracts are isolated from dried plants using chemical solvents as separation media.
This results in plant cell degradation that enables only a narrow band of ingredients to be extracted, and leads to a host of other limitations. These limitations include poor reproducibility, low specific activity, deteriorated odour, poor shelf-life stability, minimum product differentiation, and inconsistent incoming raw materials. Zeta Fraction technology selectively isolates intracellular components from living plants and marine sources to produce a much wider range of bioactive cosmetic ingredients able to capture the powerful synergy that exists within plant cells. Also instead of using external solvents as separations media, Zeta Fraction technology preserves the inherent osmotic pressure of the plant cell juice and uses it as a separations medium. Targeted fractions are mechanically and gently separated based on their electrokinetic (zeta) potential. The result is a wide range of multi-targeted benefits which are not always obtained through conventional plant extraction technology, including: minimising formation of reactive oxygen species and free radicals (DPPH: 2,2-diphenyl-1-picrylhydrazyl), preventing oxidative damage from sunlightgenerated singlet oxygen, ensuring photostabilisation of active product ingredients susceptible to UV radiation, showing increased effectiveness of cosmetic ingredients, showing COX-2 inhibitory activity, demonstrating MMP-9 inhibitory activity.
