2-Bromo-2-Nitropropane-1 ●
TL;DR. This ingredient is a preservative used to control bacteria and fungi in water-based personal care formulas. It is typically used at very low levels because it is a formaldehyde-releasing system.
What does 2-Bromo-2-Nitropropane-1 do in a cosmetic formula?
This ingredient is a preservative used to control bacteria and fungi in water-based personal care formulas. It is typically used at very low levels because it is a formaldehyde-releasing system.
Is 2-Bromo-2-Nitropropane-1 clean?
This ingredient has significant clean-standard friction because it is a formaldehyde donor and can be associated with sensitization in some users. It also has formulation restrictions because nitrosamine formation is a concern when paired with certain amine-containing ingredients.
Is 2-Bromo-2-Nitropropane-1 sustainable?
This material is synthetic and not a renewable plant or mineral-derived input. It is not valued in sustainability frameworks because of its halogenated structure, reactive breakdown pathway, and aquatic-impact concerns.
Is 2-Bromo-2-Nitropropane-1 COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. From a Green Chemistry perspective, it has weak alignment because it relies on nonrenewable synthetic chemistry and a preservation mechanism tied to reactive decomposition products.
How does 2-Bromo-2-Nitropropane-1 work chemically?
The molecule is a small brominated nitroalcohol that preserves by releasing reactive antimicrobial species, including formaldehyde under use conditions. Typical regulatory use is up to about 0.1% in cosmetics, and formulators generally keep it away from amines and strongly alkaline conditions because stability and nitrosamine-control issues become more relevant.
