Riboflavin ●
TL;DR. This ingredient is primarily used as a yellow colorant and skin-conditioning vitamin in beauty and personal care products. It can also support antioxidant-positioned formulas, although its practical role is often color and claims support rather than preservation.
What does Riboflavin do in a cosmetic formula?
This ingredient is primarily used as a yellow colorant and skin-conditioning vitamin in beauty and personal care products. It can also support antioxidant-positioned formulas, although its practical role is often color and claims support rather than preservation.
Is Riboflavin clean?
It is generally well tolerated at cosmetic use levels and has little clean-standard friction. The main formulation caveat is sensitivity to light, which can affect color and potency over time.
Is Riboflavin sustainable?
This material can be made by fermentation from carbohydrate feedstocks or by synthetic routes, so sourcing depends on the supplier. It is water-soluble, used at low levels, and is not known for environmental persistence or bioaccumulation concerns.
Is Riboflavin COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulas when the grade meets the standard’s source, processing, and non-GMO requirements. It aligns best with Green Chemistry when produced by fermentation, with renewable inputs, low use levels, and good biodegradability.
How does Riboflavin work chemically?
The molecule is a water-soluble, conjugated heterocycle with a ribityl side chain, which gives it strong yellow coloration and light sensitivity. It is typically used at very low levels for color or skin-conditioning claims, and it is more stable in acidic to neutral systems than in alkaline formulas or clear, high-light packaging.
