CI 77742 ●
TL;DR. This ingredient is a violet inorganic colorant used to tune shade in makeup, nail products, soaps, and some personal-care formulas. It contributes opacity and color rather than skin-care activity.
What does CI 77742 do in a cosmetic formula?
This ingredient is a violet inorganic colorant used to tune shade in makeup, nail products, soaps, and some personal-care formulas. It contributes opacity and color rather than skin-care activity.
Is CI 77742 clean?
From a clean-beauty perspective, it is generally a low-reactivity mineral-type pigment with low skin-sensitization concern when cosmetic grade and contaminant-controlled. The main scrutiny is purity, especially trace metals, and whether the formula's use area is permitted by local color-additive rules.
Is CI 77742 sustainable?
It is a synthetic inorganic pigment made from mined mineral-derived feedstocks, and production involves high-temperature processing. It does not biodegrade like an organic molecule, but its very low solubility limits mobility and bioavailability in rinse-off pathways.
Is CI 77742 COSMOS-approved?
It is permitted as a mineral or inorganic colorant under COSMOS-natural and can be used in COSMOS-organic products as an allowed non-organic ingredient when grade and use conditions fit the standard. Its Green Chemistry profile is mixed: durable, low-reactivity, and used at low levels, but not renewable and dependent on mined feedstocks and heat-intensive processing.
How does CI 77742 work chemically?
Technically, it is an insoluble inorganic crystalline pigment built from manganese, ammonium, and phosphate units, with color coming from transition-metal electronic structure rather than soluble dye behavior. It is stable across typical anhydrous and emulsion systems, is used as a dispersed solid rather than dissolved, and needs good milling or dispersion control to prevent specking and shade drift.
