Question 4

Is INDIGOFERA TINCTORA LEAF EXTRACT COSMOS-approved?

Accepted Answer

It is generally compatible with COSMOS-natural and COSMOS-organic frameworks when the plant material and extraction process meet the standard’s requirements. It fits Green Chemistry best when made with approved solvents such as water, ethanol, glycerin, or plant oils and with minimal processing.

Question 5

How does INDIGOFERA TINCTORA LEAF EXTRACT work chemically?

Accepted Answer

This compound is a complex botanical extract containing phenolics, flavonoids, and indoxyl glycosides such as indican, which can generate blue chromophores after enzymatic cleavage and oxidation. It is typically used at low cosmetic levels, often in the 0.1% to 5% range depending on extract strength, and color-related fractions can be sensitive to light, oxidation, and formulation pH.
