What it is
Lactobacillus/Arundinaria Gigantea Leaf Ferment Filtrate is produced by fermenting the leaves of giant cane, a North American bamboo, with Lactobacillus and filtering the broth. The fermented filtrate is used as a botanical-derived conditioning and water-binding ingredient that supports skin softness and comfort. It typically appears in the water phase of a formula at modest levels.
Safety & warnings
Ferment filtrates of this kind are generally well tolerated at cosmetic use levels. As with other fermentation-derived botanicals, occasional contact sensitivity is possible in susceptible individuals; a patch test is reasonable for very sensitive skin.
Origin & sourcing
Natural-derived via fermentation; leaves of Arundinaria gigantea (giant cane bamboo) are fermented with Lactobacillus bacteria and the liquid is filtered to produce the ingredient.
