Is Rhizobian Gum a Good Ingredient?

Good, because it's a stable, fermentation-derived polysaccharide that forms a flexible film to improve the hydration feel and texture of a formula, with a low likelihood of irritation. Its inert, water-soluble nature makes it perform consistently across different formulations, which is what earns the Good rating even though its role is mainly textural.
