Safety score · 0–100

Fine

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A rice and rice-bran ferment filtrate made with Saccharomyces yeast. Rich in amino acids and peptides — widely used, generally well-tolerated.

Saccharomyces/Rice/Rice Bran Ferment Filtrate is the filtrate of a yeast fermentation on rice and rice bran substrate. The liquid contains amino acids, low-molecular-weight peptides, B-vitamins, and beta-glucans that contribute to skin conditioning and hydration. EU CosIng lists it as skin conditioning / humectant / antioxidant. No CMR, genotox, or endocrine flags; long use history via SK-II-style pitera descendants. Ferment composition is batch-dependent, which is the main quality concern. Score at upper Fine tier — strong tolerance profile, modest controlled-efficacy evidence.
