D&C Green No. 5 ●
TL;DR. This ingredient is a synthetic colorant used to give products a it hue, especially in rinses, gels, lotions, and other water-containing formats. It has no skin-care function beyond visual tinting.
What does D&C Green No. 5 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give products a it hue, especially in rinses, gels, lotions, and other water-containing formats. It has no skin-care function beyond visual tinting.
Is D&C Green No. 5 clean?
From a clean-beauty perspective, it often creates friction because many clean frameworks limit or exclude synthetic petroleum-derived color additives, even when they are legally approved and batch-certified. Sensitization is not the main concern, the issue is more about sourcing, processing controls, and restricted-list positioning.
Is D&C Green No. 5 sustainable?
This material is synthetically produced, typically from petrochemical feedstocks, rather than being plant, mineral, or fermentation derived. Like many synthetic organic dyes, it is not a strong fit for biodegradability-focused formulations and may be relatively persistent in wastewater compared with simpler, readily biodegradable ingredients.
Is D&C Green No. 5 COSMOS-approved?
It is not permitted in COSMOS-natural or COSMOS-organic formulas because it is a synthetic organic colorant outside the allowed colorant set. Its petrochemical origin and limited biodegradability fit poorly with it Chemistry preferences for renewable feedstocks, simpler degradation pathways, and lower-impact processing.
How does D&C Green No. 5 work chemically?
The molecule is a water-soluble, anionic synthetic anthraquinone colorant, typically supplied as a salt and used at very low levels because only trace amounts are needed for visible tint. It is generally compatible with aqueous systems, but final shade and clarity can shift with pH, ionic strength, and interactions with cationic polymers or surfactants.
