Results showed that while the growth of pure cultures of pathogenic Staphylococcus aureus and Cutibacterium acnes strains linked to skin conditions were inhibited by xylitol.
A study published in the Korean Journal of Microbiology1 showed Xivia Xylitol from DuPont Nutrition & Biosciences (Kantvik, Finland) has a positive effect on skin microbial growth. The researchers’ aim was to investigate whether Xivia Xylitol could have a potential role in skin microbial growth. The growth of certain skin bacteria, as pure cultures, was measured in the presence of xylitol. Results showed that while the growth of pure cultures of pathogenic Staphylococcus aureus and Cutibacterium acnes strains linked to skin conditions were inhibited by xylitol, the growth of skin commensal Staphylococcus epidermidis strain was not affected.
“In Finland we have a long history in the sustainable production of xylitol as well as research into the health benefits of xylitol, and in particular, its caries-preventing activities,” said Kirsti Tiihonen, PhD, senior research and development manager, DuPont Nutrition & Biosciences, in a press release. “DuPont’s xylitol manufacturing technology allows the use of a minimum amount of chemicals, water, and energy and thus, shows a lower carbon footprint compared to conventional processes.”
“Xylitol is utilized due to its hydrating properties within skin care products, and the research is showing interesting abilities for xylitol to protect the skin barrier,” explains the study’s co-author Heli Anglenius, PhD, in a press release. “The study results demonstrated that xylitol also has benefits not only to control oral pathogen Streptococcus mutans but also to controlling skin microbes. The results are interesting, as xylitol could benefit in situations where there is a dysbiosis in the skin microbiota and how to balance it.”
“This new data is certainly exciting to help promote the use of our Xivia Xylitol outside of the traditional space of chewing gum and oral-care applications,” said Christopher Spontelli, global product line manager, sweeteners, DuPont Nutrition & Biosciences.
