Riboflavin ●
TL;DR. This ingredient is primarily used as a yellow colorant and skin-conditioning agent in personal care formulas. It can also support antioxidant positioning, although its visible color and light sensitivity usually drive practical use levels.
What does Riboflavin do in a cosmetic formula?
This ingredient is primarily used as a yellow colorant and skin-conditioning agent in personal care formulas. It can also support antioxidant positioning, although its visible color and light sensitivity usually drive practical use levels.
Is Riboflavin clean?
This ingredient is generally well tolerated and does not sit on major clean-beauty restricted lists. The main formulation considerations are potential yellow staining at higher levels and the need to manage light exposure.
Is Riboflavin sustainable?
This material can be produced by fermentation, which gives it a favorable renewable-sourcing profile when that route is used. It is water soluble, used at low levels, and not associated with persistence or bioaccumulation concerns.
Is Riboflavin COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic standards when made through accepted natural or fermentation-based processes and documented accordingly. From a Green Chemistry perspective, it aligns well when sourced by fermentation, with low use levels and good biodegradability.
How does Riboflavin work chemically?
The molecule is a water-soluble isoalloxazine chromophore attached to a ribityl side chain, which explains its strong yellow color and sensitivity to light. It is typically used at very low color-correction or conditioning levels, is more stable in acidic to neutral systems, and should be protected from strong light and alkaline pH.
