Red 40 Lake ●
TL;DR. This ingredient is a synthetic colorant used to give products a stable bright red shade. Because it is insoluble, it is useful in anhydrous products, pressed powders, sticks, and coated tablets where color migration needs control.
What does Red 40 Lake do in a cosmetic formula?
This ingredient is a synthetic colorant used to give products a stable bright red shade. Because it is insoluble, it is useful in anhydrous products, pressed powders, sticks, and coated tablets where color migration needs control.
Is Red 40 Lake clean?
Clean-beauty programs often flag it because it is a synthetic colorant and may require batch certification for trace impurities or metals. It is allowed in conventional cosmetics within regulatory limits, but it has more restricted-list friction than mineral or plant-derived colorants.
Is Red 40 Lake sustainable?
This material is generally made from petrochemical feedstocks and then converted into an insoluble pigment form. It is not a strong fit for biodegradability or renewable-sourcing goals, although use levels are usually low.
Is Red 40 Lake COSMOS-approved?
This ingredient is not aligned with COSMOS-natural or COSMOS-organic standards because synthetic colorants of this type are not permitted. From a Green Chemistry view, the main drawbacks are fossil-based feedstocks, multi-step synthesis, and limited biodegradability.
How does Red 40 Lake work chemically?
The molecule belongs to the synthetic azo colorant family and is rendered insoluble by binding the soluble dye to an aluminum-based substrate. Typical use is at low color-adjustment levels, often below 1 percent, and it is selected when formulators need better bleed resistance than a water-soluble colorant can provide.
