About
A blend of the polysaccharide levan with simple sugars (fructose, glucose, sucrose) — a humectant/film-former that gives soft hydration and skin feel.
This ingredient is a fermented mixture of levan (a fructose-based biopolymer made by certain microbes such as Zymomonas or Bacillus) plus residual fructose, glucose, and sucrose from the fermentation feedstock. Levan acts as a humectant and forms a thin, breathable film on skin, contributing soft tactility and modest water-binding. The simple sugars are skin-compatible humectants. No CMR, endocrine, or GHS hazards; safety is generally inferred from related polysaccharide ingredients used in food and skincare. Adequate preservation is required because the sugar fraction can support microbial growth.
