Bumetrizole ●
TL;DR. This ingredient is primarily a UV absorber and light stabilizer, used to protect formulas, dyes, fragrances, and packaging-sensitive components from UV-driven discoloration or degradation. It is not typically treated as a consumer-facing sunscreen active in many markets.
What does Bumetrizole do in a cosmetic formula?
This ingredient is primarily a UV absorber and light stabilizer, used to protect formulas, dyes, fragrances, and packaging-sensitive components from UV-driven discoloration or degradation. It is not typically treated as a consumer-facing sunscreen active in many markets.
Is Bumetrizole clean?
From a clean-beauty perspective, this ingredient faces friction because it is a synthetic UV-absorbing stabilizer with persistence concerns and limited alignment with ingredient-restriction frameworks. It is not a low-concern botanical, mineral, or readily biodegradable material.
Is Bumetrizole sustainable?
This material is synthetically produced, generally from petrochemical feedstocks, and is not considered readily biodegradable. Its environmental profile is the main sustainability drawback, especially where persistent UV absorbers are screened conservatively.
Is Bumetrizole COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards for typical cosmetic use. From a Green Chemistry lens, it scores poorly on renewable sourcing and biodegradability, even though it can improve product stability at low levels.
How does Bumetrizole work chemically?
The molecule is a small, lipophilic heteroaromatic UV absorber with phenolic and triazole-type ring features that dissipate absorbed UV energy through photostable tautomerization pathways. It is used at low stabilizing levels, is poorly water-soluble, and is more relevant in oil phases, coatings, plastics, or color-protection systems than in water-rich formulas.
