Anthocyanins ●
TL;DR. This ingredient is used mainly as a natural colorant, especially for pink, red, purple, and blue tones that can shift with formula pH. It may also add antioxidant activity, but its primary formulation role is pigmentation.
What does Anthocyanins do in a cosmetic formula?
This ingredient is used mainly as a natural colorant, especially for pink, red, purple, and blue tones that can shift with formula pH. It may also add antioxidant activity, but its primary formulation role is pigmentation.
Is Anthocyanins clean?
From a clean-beauty perspective, this ingredient is generally well tolerated and not a common restricted-list concern. The main quality considerations are plant-source consistency, residual extraction solvents, and possible trace impurities from agricultural sourcing.
Is Anthocyanins sustainable?
This material is typically derived from renewable botanical sources such as fruit, vegetable, or flower materials, including potential food-industry side streams. It is expected to be biodegradable and has low persistence concerns, with sustainability depending mostly on farming inputs and extraction methods.
Is Anthocyanins COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic standards when obtained from approved plant sources using permitted extraction processes. Its Green Chemistry profile is strongest when produced by water or ethanol extraction from renewable biomass, with low persistence and minimal processing burden.
How does Anthocyanins work chemically?
The molecule is a water-soluble polyphenolic glycoside with a pH-sensitive charged aromatic system, which is why color can move from red in acidic systems toward purple, blue, or less stable forms as pH rises. Typical use depends heavily on extract strength, but it is usually used at low colorant levels, and stability improves with acidic pH, chelators, oxygen control, and protection from heat and light.
