Is Oryza Sativa  Lees Extract clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally well accepted and is not a common restricted-list concern.

Accepted Answer

It is a complex extract containing carbohydrates, amino acids, peptides, organic acids, minerals, and phenolic antioxidant compounds from fermented grain residue. Supplier use levels are commonly in the 0.5% to 5% range, and it is best handled in preserved water-based systems at skin-friendly pH with attention to color, odor, and batch variability.
