Blue 1 Lake ●
TL;DR. This ingredient is a synthetic colorant used to give cosmetics and personal care products a stable it shade. It is used where an insoluble pigment is preferred, such as pressed powders, makeup, soaps, and coated products.
What does Blue 1 Lake do in a cosmetic formula?
This ingredient is a synthetic colorant used to give cosmetics and personal care products a stable it shade. It is used where an insoluble pigment is preferred, such as pressed powders, makeup, soaps, and coated products.
Is Blue 1 Lake clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic colorant and is excluded by many natural-focused standards. It is generally used at very low levels, but brands may review it for colorant compliance, trace impurity controls, and regional use permissions.
Is Blue 1 Lake sustainable?
This material is typically derived from petrochemical dye chemistry and mineral-based aluminum processing. It is not a strong fit for biodegradability-focused formulas because it is designed to be color-stable and insoluble.
Is Blue 1 Lake COSMOS-approved?
It is not permitted in COSMOS-natural or COSMOS-organic products because the standard does not allow this type of synthetic cosmetic colorant. Its Green Chemistry profile is weak due to nonrenewable feedstocks, multistep synthesis, and limited biodegradability.
How does Blue 1 Lake work chemically?
The molecule is an anionic triphenylmethane dye immobilized on an aluminum-based insoluble substrate, which improves dispersion in solid and anhydrous systems and reduces bleeding versus a soluble dye. Use levels are typically very low and adjusted by shade target, and formulators must check pH, dispersibility, and regional colorant limits for the product category.
