FD&C Blue 1 Lake ●
TL;DR. This ingredient is an insoluble colorant used to give products a vivid it shade. It is mainly used in makeup, personal care, and some hygiene formulas where stable visual color is needed rather than skin benefit.
What does FD&C Blue 1 Lake do in a cosmetic formula?
This ingredient is an insoluble colorant used to give products a vivid it shade. It is mainly used in makeup, personal care, and some hygiene formulas where stable visual color is needed rather than skin benefit.
Is FD&C Blue 1 Lake clean?
From a clean beauty perspective, it often has restricted-list friction because it is a synthetic certified color additive with specification limits for trace metals and manufacturing residues. It is generally used at low levels, and sensitivity is uncommon but possible in color cosmetics and leave-on products.
Is FD&C Blue 1 Lake sustainable?
This material is petrochemical-derived and produced through multi-step synthesis, then made insoluble on a mineral substrate. It is not a strong fit for biodegradability-focused standards because synthetic dyes and their insoluble pigment forms can persist in wastewater and sludge streams.
Is FD&C Blue 1 Lake COSMOS-approved?
It is not permitted in COSMOS-natural or COSMOS-organic formulations because synthetic color additives fall outside the standard’s allowed colorant approach. Its Green Chemistry fit is limited by nonrenewable feedstocks, multi-step processing, and weak biodegradability alignment.
How does FD&C Blue 1 Lake work chemically?
The molecule is a synthetic triarylmethane dye converted into an insoluble pigment form by association with an aluminum-containing substrate, which improves bleed resistance versus the soluble dye. Use levels are typically low and shade-driven, and formulators must manage dispersion quality, regulatory color-additive limits by region and product type, and potential color shift in very reactive systems.
