INCI: Xylitol

Our skin is the largest organ in the human body. It plays a key role as a protective barrier for the body and is home to an ecosystem of microorganisms. Most of these microorganisms that reside on the skin are beneficial to skin health.

Disturbances in the stratum corneum and the composition of the skin microbiome have been linked to skin health. Find out more.

The skin microbiome has only recently emerged as a focus area for the beauty and personal care industry, shifting from a static view to a dynamic and complex ecosystem of microbes living on the skin.

GENENCARE® XL is an active ingredient of upcycled, sustainable origin, easily dissolved in water and suitable for applications in skin care, hair care, hygiene products and solid cosmetics.

From the Forest to the Skin: GENENCARE® XL Sustainability Profile

GENENCARE® XL is a xylitol upcycled from a wood processing side stream. The beech wood raw material is sustainably sourced and and certified Forest Stewardship Council (FSC) and Programme for the Endorsement of Forest Certification (PEFC). We are committed to a circular economy from sourcing to production, and use minimal amounts of energy and chemicals compared to conventional xylitol.


A Benchmark for Sustainable Xylitol

Extracted via catalytic hydrogenation without the use of any solvents, the production of GENENCARE® XL follows the woodbased circular economy concept, unique to IFF.
