Nordihydroguaiaretic Acid ●
TL;DR. This ingredient is used primarily as an antioxidant, helping slow oxidation of oils, fragrance components, and other oxidation-prone materials in a formula. It is most relevant in leave-on products where small amounts can support formula stability.
What does Nordihydroguaiaretic Acid do in a cosmetic formula?
This ingredient is used primarily as an antioxidant, helping slow oxidation of oils, fragrance components, and other oxidation-prone materials in a formula. It is most relevant in leave-on products where small amounts can support formula stability.
Is Nordihydroguaiaretic Acid clean?
From a clean beauty perspective, this is a high-scrutiny antioxidant rather than a routine choice because of its history of food-use restrictions and dose-related oral safety findings. In cosmetics, it is typically used at low levels, with irritation and sensitization assessed through the finished formula.
Is Nordihydroguaiaretic Acid sustainable?
This material can be plant-derived or synthetically made, so its sustainability profile depends heavily on sourcing and purification. Plant sourcing needs traceability, while synthetic routes add solvent and processing considerations; public biodegradation data are limited.
Is Nordihydroguaiaretic Acid COSMOS-approved?
It is not a straightforward COSMOS-organic fit as an isolated antioxidant unless the supplier can document compliant natural-origin sourcing and processing. From a Green Chemistry view, it has a favorable role as a low-dose oxidation stabilizer, but alignment depends on renewable feedstock, solvent choice, and waste control.
How does Nordihydroguaiaretic Acid work chemically?
The molecule is a bis-phenolic lignan, and its antioxidant behavior comes from phenolic hydrogen donation that helps interrupt radical oxidation pathways. It is generally used at very low concentrations, often around 0.01 to 0.1 percent, and works best when solubilized in the oil phase or a suitable solvent system.
