TL;DR. This ingredient is used primarily as a natural colorant, adding pink, red, purple, or brownish tones depending on pH and formulation context.
What does Grapecolour Extract do in a cosmetic formula?
This ingredient is used primarily as a natural colorant, adding pink, red, purple, or brownish tones depending on pH and formulation context.
Is Grapecolour Extract clean?
From a clean-beauty perspective, it is generally viewed as low-friction because it is plant-derived and not a common restricted-list ingredient. Sensitivity is uncommon, but color extracts can bring batch variability and trace botanical impurities that depend on processing quality.
Is Grapecolour Extract sustainable?
This material is renewable and often sourced from fruit-skin or pomace streams, which can support byproduct use. It is expected to be biodegradable, with the main sustainability variables being farming inputs, extraction solvent, and concentration method.
Is Grapecolour Extract COSMOS-approved?
It is generally permitted in COSMOS-natural and can qualify for COSMOS-organic when the agricultural input, extraction solvents, and preservatives meet the standard. It fits Green Chemistry best when made with water or ethanol extraction, low-residue processing, and responsible agricultural sourcing.
How does Grapecolour Extract work chemically?
This material is a botanical color extract rich in anthocyanin-type polyphenols, whose visible shade shifts with pH, metal ions, light exposure, and oxidation. It is typically most color-stable in acidic systems, and formulators often pair it with chelators, antioxidants, and opaque packaging to reduce fading.
